Knowlege is power (forgive the pun!)
Many of the questions you may be thinking about are answered below. We think it's important that things are black & white.
01.
What does supplied 'at cost' actually mean?
‘Supplied at cost' means you are given one fixed price that reflects the genuine, real-world cost of supplying the Battery Energy Storage System — and nothing more.
That price includes the manufacturer’s factory cost, international shipping and logistics, UK import duties, compliance and certification, required insurance, and the essential administration needed to operate properly and transparently. These are unavoidable costs.
A small contingency is built in to absorb normal variations such as currency movements, freight changes, or customs timing, so the price you are quoted remains the price you pay.
There are no mark-ups, commissions, or profit margins. No sales incentives, no hidden extras. The price exists solely to cover the true cost of supply.
The outcome is a clear, fair, fixed price that removes uncertainty and avoids inflated retail pricing.
02.
Why is this so much cheaper than big brands?
If you’re comparing prices with well-known battery brands, the difference comes down to how the system is supplied, and the fact that large manufacturers have shareholders to satisfy and profit targets to meet.
With most big brands, the price you see includes several layers of cost added along the way. By the time it reaches a household, you’re paying not just for the battery, but for the way it has been packaged, distributed, and sold. That’s why 13.5 kWh systems from GivEnergy are commonly around £10,000–£12,000, and Tesla Powerwall systems around £8,000–£10,000.
Here, the system is bought directly from the manufacturer, shipped in container volumes, and supplied at cost, with no added commercial layers. The result is a 15 kWh system at roughly a quarter to a third of typical branded pricing, while still meeting UK compliance requirements and including warranty cover. The lower starting price simply means you have far less to recover before the system starts paying for itself.
03.
Who is GeePower?
GeePower is an established energy technology manufacturer supplying battery systems to both residential and commercial markets internationally.
Engagement with GeePower began in 2024, followed by a factory visit in February 2025 to review manufacturing processes, quality control, and safety systems first-hand. Throughout 2025, GeePower has been committed to developing the Terra A Series Battery Energy Storage System specifically for the UK market, aligned with local regulatory and grid-connection requirements.
The Terra A Series Battery Energy Storage System has now been independently tested to the required UK standard and is listed by the Energy Networks Association (ENA). This confirms it has been assessed against the appropriate criteria and can be used in compliant UK installations when configured correctly. Systems are genuine, tested, traceable, and supplied with a full manufacturer warranty — giving you confidence on par with established commercial suppliers.
04.
Why do I only receive my invoice after installation?
You pay on order as you normally would for anything purchased online. Your payment confirms your order, secures your system, and allows everything to progress as planned. You receive the usual payment confirmation and receipt, exactly as you would expect.
The only document that comes later is the formal VAT invoice, and that timing is simply to protect you. Under UK VAT rules, the 0 % rate only applies once a Battery Energy Storage System has been fully installed. Issuing the VAT invoice after installation safeguards the 20 % VAT saving that would otherwise apply.
In practical terms, nothing is delayed and nothing is missing. Your order is confirmed, your payment is properly recorded, and your system moves forward as normal. Once installation is complete, a single VAT invoice is issued covering the finished system — locking in the VAT relief and keeping your overall cost as low as possible.
05.
Will I have to pay VAT?
No. Battery Energy Storage Systems installed in residential properties currently qualify for 0 % VAT under UK energy-saving materials rules.
The VAT position is determined by what is supplied: a qualifying battery system installed as part of a residential energy-saving upgrade. The formal VAT invoice is issued after installation so it accurately records the supply of a completed, installed system, which is what the legislation requires.
For you, the outcome is simple and beneficial. The correct structure protects the 20 % VAT saving that would otherwise apply, without changing how you order or pay. Everything works as you would normally expect — the VAT treatment simply reflects the finished installation and keeps your overall cost as low as the law allows.
06.
How do payments work?
When you place your order, payment is taken in the same way you would expect for any standard online purchase. You receive a clear order confirmation and receipt, and your payment is recorded against your system.
Your payment is held in a ring-fenced client account and released only at defined stages to the manufacturer. An initial portion is released once manufacturing is scheduled, with the balance released to the manufacturer only when the system has been completed and cleared for shipment. This staged release follows standard international manufacturing practice, allowing for production checks, batch inspection, and verification before final payment. All shipments are fully insured door-to-door, from the factory through to arrival in the UK.
You also receive a clear sales agreement setting out these arrangements in writing. If you pay by credit card or approved finance, your purchase is covered by Section 75 of the Consumer Credit Act, which applies in the same way it does to other qualifying purchases. Taken together, this means payments are handled in a clear, controlled, and familiar way from order through to delivery.
07.
Would I be eligible for a government loan?
Possibly — and the good news is that the scheme is intended to be available to all households, not just those on low incomes.
Under the UK Government’s Warm Homes Plan, government-backed, low- and zero-interest loans have been announced to support home energy upgrades, including batteries. The intention is to make clean energy technologies more accessible to everyone by spreading the upfront cost over time.
Eligibility rules, application routes, and timings are set by government and may change, so the final decision will always sit with the scheme provider at the time you apply. When a loan option is live, we’ll explain how it works alongside purchasing outright, but the most up-to-date eligibility check will always be through the official scheme itself.
08.
What if I change my mind?
You are protected by UK consumer cancellation rights, which allow you to change your mind before any manufacturing or shipping commitments are made on your behalf, and receive a refund in line with those protections. By default, we do not start processing your order during the 14-day cooling-off period.
If you request that your order is processed immediately, we can begin arranging manufacturing, logistics, and other services straight away. In that case, your right to cancel may be reduced or lost once those services have been carried out, as permitted under consumer law. This option is there so your order can move forward without unnecessary delay if that’s what you prefer.
Everything about cancellations and refunds is set out clearly in your sales agreement before you confirm your order. By default, we do not begin processing your order during the 14-day cooling-off period, so you can cancel within that time and receive a full refund. If you ask us to start processing your order immediately, cancellation is no longer available once that work has begun, as permitted under consumer law. There are no hidden conditions or penalties — just a clear choice, clearly explained.
09.
Can I spread payments?
Possibly — this depends on how you choose to pay.
The organisation does not provide finance or credit facilities directly. However, many customers choose to spread the cost of their purchase using options made available by their own bank, card provider, or an independent finance provider.
Some debit and credit card providers offer instalment features or payment plans, and customers may also choose to use third-party finance providers independently, subject to the terms offered by those providers. Any such arrangement is made directly between you and your lender and is separate from your purchase with the organisation.
From time to time, government-backed schemes may also be available to support household investment in energy efficiency and low-carbon technologies, including programmes offering low- or zero-interest loans, such as those announced under the Warm Homes Plan. Availability, eligibility, and terms are set by the scheme provider and may change, so customers should check current government guidance or speak to their chosen provider for details.
If you choose to pay by credit card or regulated finance, you may also benefit from the protections offered by your card issuer or finance agreement, in line with their terms and applicable consumer credit law.
10.
What if prices change prior
to delivery?
Once your order is accepted, the price set out in your sales agreement is fixed.
There are no hidden extras and no post-order price increases, even if exchange rates, shipping costs, or other external factors change after you’ve ordered.
This price certainty is possible because your order is placed and costed at the time of purchase, with payments handled on an order-specific, ring-fenced basis and supplier commitments made for that shipment.
A small contingency is included within the at-cost price to help manage normal external cost movements without passing them on to customers.
As a result, households are not exposed to day-to-day market fluctuations once an order has been placed, and the price you agree is the final price you pay.
11.
How long does delivery take?
From the point your system enters production, delivery to the UK typically takes around 7–10 weeks. This reflects the normal end-to-end timeline for manufacturing, international transport, and UK intake for equipment of this type.
That period covers the full journey: factory build, testing and packing, sea freight, customs clearance, and onward transport to the UK warehouse. Large battery systems are moved in scheduled container shipments, which is the most reliable and cost-effective way to transport heavy equipment internationally and keep costs down for everyone in the buying group.
As your order progresses, you’ll receive automatic updates at each stage, so progress is always visible rather than assumed. This allows you to see where your system is in the process, understand what’s happening next, and plan installation and delivery arrangements with confidence rather than uncertainty.
12.
What if shipping is delayed?
International shipping is generally reliable, but as with any global freight movement, it can occasionally be affected by factors outside anyone’s control, such as weather conditions, port congestion, or routine customs checks.
If a delay does occur, your system remains fully insured throughout the entire journey, from the point it leaves the factory until it arrives at the UK warehouse. Insurance and tracking remain in place during transit, so the system itself is protected even if timelines move slightly.
If schedules change, you’ll be kept informed with clear updates and revised expectations. The important point is that progress remains visible and managed throughout, so even when shipping takes a little longer than planned, you’re never left uncertain about where your system is or what’s happening next.
13.
How do I receive my system once it arrives in the UK?
When your system arrives in the UK, it is delivered to an independent third-party warehouse. Once it has been received and logged, you’ll be notified that it is ready for release.
From that point, collection or onward delivery is arranged directly between you and the warehouse provider.
You may collect the system yourself, or your installer can collect on your behalf. Collection is booked directly with the warehouse. In some cases, a small picking or handling fee may apply, which is agreed and paid directly to the warehouse provider.
If you prefer home delivery, this can be arranged anywhere in mainland UK. Delivery is organised and paid for directly with the warehouse or its nominated carrier at their standard rate.
This structure is deliberate. Just like installation, we remove ourselves from the logistics stage to keep costs low and avoid acting as a middleman. You arrange collection or delivery directly, which means no bundled margins and no unnecessary layers. It also gives you flexibility to agree timings that suit you and adjust dates easily if plans change, while we continue to manage the collective purchase and documentation in the background.
14.
Who installs my battery system?
Installation is carried out by a qualified electrician chosen by you. This means you can work with someone you already know and trust, agree the installation price directly, and arrange a date that suits your household.
If you do not already have an installer, you can select one from the Which? Trusted Traders directory. Customers are able to use this recognised service to find an independently vetted installer, while remaining free to choose who carries out the work in their home.
Once you have agreed the installation price and a provisional date, your installer completes a simple onboarding form confirming the agreed amount. For administrative and VAT purposes, the installer is then engaged as a subcontractor for that specific installation. This ensures the correct documentation is in place and that the combined supply and installation qualifies for the current 0% VAT treatment under UK rules.
We deliberately do not bundle installation into a fixed package. By allowing you to appoint your own electrician — or select one through Which? — you stay in control of timing, costs, and who is working in your property. You agree the labour cost and installation date directly with your installer (no mark-up), while we manage the formal contracting, invoicing, and compliance framework in the background so everything remains properly structured and documented from start to finish.
15.
How long does installation take?
Each system is supplied with a pre-wired connection hub. This standardises the installation layout, reduces on-site complexity, and ensures the system arrives factory-prepared for straightforward connection.
Because the system is pre-wired and ready-configured, installation is typically efficient and well-defined. In most cases, it is completed within a few hours and ordinarily on the same day.
A pre-wired setup also helps keep installation costs clear and predictable. You agree the installation price directly with your chosen electrician based on a defined scope of work, rather than an open-ended configuration process.
Your installer carries out the work in accordance with UK electrical standards, including BS 7671, and completes the required electricity-network notification as part of the documented completion stage.
Installation funds are held securely and are only released once you confirm that the work has been completed satisfactorily. This ensures payment follows completion and gives you reassurance that everything is properly finished before funds are released.
16.
What is the connection hub, do I have to pay extra?
Other brands do, but we do NOT. The connection hub is a pre-assembled, factory-tested control panel that forms part of your Battery Energy Storage System. It is included within your system price, so there is no additional charge.
It contains the mandatory protection and switching devices required for safe installation and is prepared in line with UK standards, including G99 compliance. This means the core control components are already correctly configured before arriving at your property.
Because the hub is supplied ready-made, your electrician does not need to source individual components or assemble a control panel from scratch. This helps reduce installation time, avoid unnecessary cost, and ensure consistent national safety standards are met.
We deliberately include the connection hub as standard. By providing a properly configured, factory-tested unit within the system price, we support safer installations, cleaner wiring layouts, and a more efficient on-site process — without adding hidden extras.
17.
How does invoicing work?
When you place your order for your Battery Energy Storage System, you pay the full system price and receive a clear order confirmation and payment receipt. The full Customer Sales Agreement is available to review before you proceed, so the structure and responsibilities are set out in writing from the beginning.
Installation is arranged separately. You agree the installation price directly with your chosen electrician, keeping control of cost and timing. Once your installer completes a simple onboarding step and confirms the agreed amount, you receive a payment request for that exact price — with no mark-up added.
When you pay the installation amount, you receive a receipt and the funds are held securely on your behalf. They are only released once the required installation evidence has been provided and you confirm the work has been completed satisfactorily.
After completion is confirmed, the installer submits their invoice and you are issued with a single coordinated invoice covering both the system and the agreed installation amount together, keeping everything properly structured under current UK VAT rules.
In short, you can review the agreement before committing, you receive a receipt each time you pay, installation funds are safeguarded until you are satisfied, and the final invoice is issued once everything is complete — preserving the current 0% VAT treatment (no VAT added).
18.
Do I need planning permission?
In almost all homes, no additional permission is required. The system is designed for indoor or properly protected installation and does not alter the external appearance of your property.
The unit is compact — approximately 650mm (W) × 396mm (D) × 830mm (H) — similar in footprint to a slim domestic appliance. It is typically installed inside a garage, utility room, or another sheltered internal space.
We have carefully considered long-term durability in UK conditions. While many products focus heavily on IP ratings (protection against water ingress), prolonged UV exposure can have a far greater long-term impact on plastics, seals, and external components. For that reason, our system is not designed for outdoor exposure, and we deliberately chose not to produce an external IP-rated version. Our priority is longevity, reliability, and safety — which is best achieved indoors or in a properly protected structure.
Because installation is internal and does not change the building’s outward appearance, the process is normally straightforward.
If you live in a listed building or designated conservation area, it is sensible to check with your local planning authority. For most households, however, no separate planning consent is required.
19.
Does my insurer need to know i have a battery?
Yes — it’s always sensible to inform your home insurer once your Battery Energy Storage System has been installed.
A home battery is a fixed addition to your property, similar to solar panels or other built-in systems. Letting your insurer know ensures the equipment is properly noted on your policy and that your building cover reflects its value. This avoids any uncertainty if you ever need to make a claim.
In most cases, insurers simply record the installation. Where systems are professionally installed to UK standards, approval is usually straightforward. Some policies may adjust slightly to reflect the added value of the equipment, while others remain unchanged.
Our system uses Lithium Iron Phosphate (LFP) battery chemistry, recognised as one of the safest available. In addition, every battery module and the inverter contain integrated fire suppression modules. In the highly unlikely event of a thermal issue, an automatic aerosol-based suppression system activates within the enclosure itself, extinguishing the issue at source before it can develop further. This built-in protection provides an additional layer of reassurance when speaking with your insurer.
20.
What is G99 certification? And why does it matter?
G99 is the official UK engineering standard that governs how generation and storage systems connect safely to the electricity grid. It ensures your system operates correctly alongside the national network and prevents risks such as voltage disturbance, back-feed, or interference with other users.
The Energy Networks Association (ENA) manages the national Type Test Register. When a product appears on that register, it confirms the equipment has been independently tested and approved for UK grid connection.
Every Terra A system supplied through us is fully G99 compliant and listed on the ENA Type Test Register. This means it has already passed the required safety, compatibility, and performance testing for use anywhere in the UK.
For you, this brings two important benefits. First, your installer can complete a straightforward installation rather than a complex pre-approval process. Second, you know your system is recognised by every UK Distribution Network Operator, protecting compliance, insurance clarity, and long-term peace of mind.
Not all products meet these standards. Whatever system you consider, it is always sensible to ask: Is it G99 compliant and listed on the ENA Type Test Register?
21.
How safe are home battery systems?
The Terra A system uses Lithium Iron Phosphate (LFP) chemistry, widely regarded as the safest form of lithium-ion technology currently available. It is specifically chosen for its thermal stability and suitability for domestic indoor environments.
LFP cells are significantly more stable than older chemistries used in many consumer batteries. They resist overheating, do not release oxygen in the unlikely event of failure, and have an extremely low fire probability. Industry data suggests the annual fire risk for modern home battery systems is around 0.005% per system per year, often comparable to — or lower than — common household appliances such as tumble dryers.
In addition, every battery module and the inverter contain integrated aerosol-based fire suppression. In the highly unlikely event of a thermal issue, the suppression system activates automatically within the enclosure, extinguishing the issue at source. Continuous electronic monitoring through the Battery Management System (BMS) provides further protection against overcharging, overheating, and abnormal operation.
The result is a multi-layered safety design that meets UK standards and is intended for safe installation inside normal residential properties.
22.
Can the system send (export) power back to the grid?
No — the system is intentionally configured as non-exporting. This is a deliberate and strategic decision for your benefit.
Our system is designed to store lower-cost off-peak electricity and use it during more expensive peak periods. This keeps the setup simple, compliant, and focused entirely on reducing your household energy bills.
Selling electricity back to the grid is usually linked to larger and more expensive rooftop solar installations, and export payments are often modest, meaning your actual payback is a decade from now.
Our approach is practical: buy electricity cheaply at night, store it, and use it yourself when prices are higher — keeping the savings within your home rather than exporting energy for comparatively small returns.
The inverter is PV-ready, which simply means it has dedicated inputs that allow solar panels to be connected in the future. It is not configured for export, but it can accept solar charging.
For example, in the event of a power outage, a suitable portable solar panel — similar to those used for camping or emergency backup — could be connected to provide gentle trickle charging. This adds flexibility and resilience, without changing the system’s core purpose of bill reduction through smart energy storage.
23.
What’s in the box(es)?
Every delivery contains everything needed for a complete home Battery Energy Storage System, except property-specific cabling.
You will receive:
- Three × 5 kWh Lithium Iron Phosphate (LFP) battery modules (15 kWh total), each with integrated fire suppression and its own Battery Management System (BMS).
- A programmable inverter, also fitted with its own integrated suppression and control electronics.
- A pre-wired, G99-compliant connection hub with the required protection and switching devices already assembled.
- Heavy duty caster wheels for safe positioning and movement.
- Connectors, documentation, and manuals for installation and operation.
- A happy smile, knowing that your bills are about to plummet!
Because every home’s wiring layout is different, your electrician supplies the appropriate cabling locally. This ensures the correct length and specification for your property, avoids unnecessary materials, and keeps installation efficient and properly tailored to your home.
24.
What if energy prices fall?
Energy prices fall? It’s possible — and pigs might fly — but the system does not depend on prices rising to work.
Your Battery Energy Storage System is designed around timing, not prediction. It works by buying electricity when it is cheaper and using it when it would otherwise cost more. As long as there remains a gap between lower off-peak rates and higher daytime rates — which continues to underpin UK smart tariff policy — the opportunity to save remains.
Even if overall prices reduce, suppliers still differentiate between peak and off-peak demand. That pricing spread is what the system leverages. You store energy when it is cheapest and use it later, reducing exposure to higher daytime rates.
The benefit therefore comes from control and load-shifting, not speculation. Whether prices rise, soften, or move unpredictably, the model is built around practical tariff flexibility — focusing on repeatable, everyday savings within your control.
25.
How does this compare to solar + battery?
A typical UK solar-plus-battery installation (4–6 kW array with 13 kWh+ storage) commonly costs £12,000–£16,000, with premium brands reaching £18,000–£22,000+.
That is a significant upfront commitment, and the entire five-figure sum has to be recovered before you see any true net gain. Performance also depends on roof position, ability to clean them, daylight hours, weather, and seasonal variation.
Our approach is deliberately different. The Battery Energy Storage System is built around tariff timing, not sunshine. It stores lower-cost off-peak electricity and uses it during higher-priced periods. Our aim is to keep the system price around £2,999 (subject to exchange rates, material costs, and shipping) — but roughly a quarter of many major-brands.
With savings of around £1000 per year, and higher-use homes seeing up to £1,500 per year, payback is often around 24-36 months, depending on tariff and usage.
Don’t rely on headline figures. Look at the total installed cost, realistic annual savings, and how many years it takes before you are genuinely ahead. Then decide which route makes financial sense for your household.
Being candid, from our perspective solar technology just isn’t there yet, with mid-priced solar panels only 19-22% efficient, and that’s before they get dirty! Do your homework - it doesn't make sense. (Not yet)
26.
How does my order support the community?
Every order supports the wider public-benefit purpose of The 22:23 Community Interest Company.
Your system is priced “at cost.” Instead of adding a retail profit margin, a small contingency allocation (approx 5%) is included within the total price.
This is not profit. It is a protective buffer designed to absorb fluctuations in exchange rates, shipping costs, insurance, or compliance requirements — ensuring that once you place your order, your price remains stable and the shared container shipment can be completed smoothly.
When a container is delivered and reconciled, any unused portion of that contingency does not become private profit. As a Community Interest Company with no shareholders, any surplus is retained within the organisation to build prudent reserves and support its public-benefit objectives, including hardship-related support aligned with relieving fuel poverty.
In this way, a mechanism designed for financial stability also reinforces our wider mission. Your order protects the integrity of the buying group, helps maintain stable pricing for all participants, and — where surplus arises — contributes to long-term community resilience rather than private gain.
27.
Is the organisation registered?
Yes. The 22:23 Community Interest Company is a UK-registered Community Interest Company (CIC), registered in England and Wales.
A CIC is a regulated legal structure designed for organisations that operate for public benefit rather than private profit. The company has no shareholders and does not distribute profits. Any surplus is retained within the organisation to support its stated public-benefit objectives.
Directors and members are legally responsible for ensuring that funds are handled properly, that accurate financial records are maintained, and that conflicts of interest are managed transparently. The organisation operates under company law and CIC regulations, and annual accounts and a Community Interest Report are filed publicly.
For households, this means your order and payment sit within a formal framework of legal accountability. There are no private owners extracting dividends — only a regulated structure designed to operate in the public interest.
That governance framework is what distinguishes the organisation from a typical commercial supplier: transparency, reporting, and public-benefit purpose are built into the legal structure itself.
28.
What happens to unused contingency funds?
If a shipment completes and not all of the contingency allocation is required — for example, if shipping, insurance, or compliance costs come in lower than expected — the unused portion does not become profit.
As a Community Interest Company with no shareholders, any surplus is retained within the organisation and applied strictly in line with its public-benefit objectives, including hardship-related support connected to relieving fuel poverty and household energy difficulty.
Support is allocated through a structured and accountable process with clear internal criteria focused on genuine need, vulnerability, and meaningful impact. All decisions are formally authorised and recorded to ensure proper oversight.
Although a CIC is only required to meet specific statutory reporting standards, our intention is to report beyond the minimum. We aim to operate with transparency, integrity, and community spirit — publishing clear information about financial stewardship and public-benefit delivery so participants can see how funds are handled.
In this way, contingency funds that are not required operationally strengthen the organisation’s wider social purpose rather than becoming private gain.
29.
What if I change supplier, or even move house?
The system is designed to be flexible.
If you switch electricity supplier or move to a new time-of-use tariff, you can simply adjust the charging and discharge windows through the control screen or app. This allows the system to align with your new off-peak periods, ensuring it continues to charge when electricity is cheapest and discharge when prices are higher.
Because the model is built around tariff timing rather than any specific supplier, you are free to change providers as the market evolves. The system adapts with you.
If you move house, you also have options. The system can remain installed — potentially increasing your property’s appeal to buyers — or it can be professionally disconnected and relocated to your new home. Its modular design and wheeled base make removal and reinstallation straightforward.
If you relocate the system, guidance is available to ensure safe reinstallation and continuity of records. If you leave it in place, ownership details can be updated accordingly.
In short, whether you change tariff, supplier, or address, your investment remains flexible and transferable.
30.
What protections are built into the system?
Every system is designed with multiple independent safety layers to protect both you and your property.
These include automatic shutdown in the event of overheating, overload, or short-circuit conditions, along with continuous monitoring through the integrated Battery Management System (BMS). If any abnormal condition is detected, the unit isolates itself immediately and will not restart until conditions are confirmed safe.
Each battery module and the inverter also contain integrated aerosol-based fire suppression modules. In the highly unlikely event of a thermal issue, the suppression system activates automatically within the enclosure, extinguishing the issue at source.
The system uses Lithium Iron Phosphate (LFP) chemistry, widely regarded as one of the safest battery chemistries available. Industry data indicates that modern home battery systems have an extremely low fire probability — often comparable to, or lower than, common household appliances such as tumble dryers.
Installations comply with UK wiring regulations (BS 7671) and the IET Code of Practice for Energy Storage Systems, and the equipment is G99 compliant for UK grid connection. The result is a layered safety design combining chemistry choice, electronic protection, physical suppression, and regulatory standards — suitable for indoor domestic installation.
31.
Do I need an electric vehicle to have a battery system at home?
No — you do not need an electric vehicle to install or benefit from a home Battery Energy Storage System.
Many electricity suppliers now offer time-of-use (often called “smart”) tariffs. These provide lower-cost electricity during off-peak hours, typically overnight, and higher rates during peak daytime periods.
A home battery allows you to store electricity during those lower-cost hours and use it later in the day. That benefit applies whether or not you own an electric vehicle.
If you decide to move onto a time-of-use tariff, you simply inform your electricity supplier that you have a home battery system and wish to switch. Suppliers now routinely support this. The battery works independently of vehicle ownership and integrates with your home’s existing electrical setup once installed by a qualified electrician.
In short, an electric vehicle is not required — the system works perfectly well as a standalone way to manage when and how you use electricity in your home.
32.
Won’t major suppliers or government bodies try to stop this?
No. In fact, wider adoption of home energy storage aligns directly with current UK energy policy.
Government and regulators actively encourage demand shifting, grid flexibility, and greater household participation in managing energy use. Time-of-use tariffs exist specifically to move consumption away from peak periods and reduce strain on the national grid. A Battery Energy Storage System simply enables households to respond to those signals more effectively.
Major suppliers design tariffs that reward off-peak usage. This system operates entirely within those structures — connecting under established grid standards and complying with UK wiring and safety regulations.
The difference is accessibility. Large suppliers often package storage within higher-cost, capital-heavy installations. Our model focuses on affordability and tariff optimisation, lowering the barrier to entry and allowing more households to participate.
In that sense, this approach doesn’t challenge policy — it accelerates it. By making storage accessible to ordinary households, it supports the same goals: smarter energy use, reduced peak demand, and greater resilience across the network.
