Best GivEnergy Alternatives UK 2026 — Battery Storage Options After Administration
Updated: May 2026 | Written by Depth of Light Ltd — MCS & NAPIT Certified Installers
⚠ GivEnergy administration — quick summary
GivEnergy Ltd entered administration in 2026. Existing batteries continue to work, but warranties are at risk and the GivEnergy app and cloud services may eventually be discontinued. If you are looking to install a new battery system, a GivEnergy alternative is now the sensible choice. Full GivEnergy administration guide here.
The GivEnergy Situation in 2026
GivEnergy was one of the UK's most popular home battery brands, with tens of thousands of systems installed across the country. The company entered administration in early 2026 after a period of well-publicised financial difficulties — many customers had already noticed disruption to support, firmware updates and the GivEnergy online portal.
If you had GivEnergy installed, your battery continues to work — the hardware is unaffected by the administration. But going forward, new GivEnergy system installations make no sense, and existing customers face legitimate concerns about warranty coverage, firmware support, and app availability.
This guide focuses on the best alternatives for people who need a new battery installation — whether because they are switching away from GivEnergy or buying a home battery for the first time. We install all of the systems below and can give you impartial advice based on your specific situation.
The Best GivEnergy Alternatives in 2026
GivEnergy was popular for good reasons: modular sizing (you could start small and add capacity), competitive pricing, and a capable monitoring app. A GivEnergy replacement should ideally offer similar advantages. Here are the four systems we recommend most.
1. SigenStor by SigEnergy Best Overall Alternative
SigenStor is our top recommendation as a GivEnergy alternative, and for good reason: it is the most direct like-for-like replacement available in the UK right now. SigEnergy is a well-capitalised, publicly listed manufacturer — a stark contrast to GivEnergy's financial situation.
Why SigenStor is the best GivEnergy replacement
- Modular sizing: 5kWh, 10kWh, 15kWh and 20kWh configurations — exactly what GivEnergy users valued. Start with what you need and expand later.
- V2H (Vehicle-to-Home) ready: If you have a compatible EV (e.g. Nissan Leaf, Kia EV6), SigenStor can power your home from your car battery. No GivEnergy product supported this.
- Integrated hybrid inverter: Single unit handles solar, battery and grid — simpler installation and fewer points of failure.
- Strong warranty: 10-year product warranty and 10-year performance warranty from a financially stable manufacturer.
- Competitive price: 10kWh system starts from around £4,500–£5,500 installed — comparable to what GivEnergy charged.

5kWh SigenStor: from £3,500 installed | 10kWh: from £4,500 | 15kWh: from £5,500. All prices include 0% VAT. Full SigenStor service page →
Best for: Homeowners who valued GivEnergy's modularity and want a reliable alternative with V2H capability and strong financial backing behind the brand.
2. Fox ESS Best Budget Choice
Fox ESS is a Chinese-manufactured battery system that has gained a solid reputation in the UK installer community. It sits at the more affordable end of the market without compromising significantly on quality.
Why Fox ESS works as a GivEnergy alternative
- Price: A 5kWh Fox ESS system can be installed from around £3,000–£3,500 — the most affordable quality option in the UK market.
- Modular: Like GivEnergy, Fox ESS batteries can be stacked to increase capacity.
- Compatible with existing solar: Fox ESS works well as a retrofit to most existing solar installations via AC coupling.
- Monitoring app: The FoxCloud app provides real-time monitoring, though it is less polished than GivEnergy's or Tesla's apps.
- UK presence: Fox ESS has a dedicated UK operation with UK-based support.
Best for: Homeowners looking for the most cost-effective option who can accept a less premium app experience and do not need V2H capability.
Not ideal for: Those who want the most reliable long-term support or the most polished monitoring experience.
3. Tesla Powerwall 3 Best Premium Option
At the top end of the market, the Tesla Powerwall 3 is the best-supported, highest-output home battery available in the UK. It costs significantly more than GivEnergy did, but the gap in quality, software and long-term support is substantial.
What makes the Powerwall 3 stand out
- 13.5kWh capacity: Larger than most GivEnergy configurations. Covers a typical UK home overnight comfortably.
- 11.5kW continuous output: More than double what GivEnergy could deliver. Powers high-demand appliances like EV chargers and heat pumps without throttling.
- Built-in solar inverter: The Powerwall 3 handles both solar and battery in a single unit — no separate inverter needed.
- Whole-home backup: During a power cut, Powerwall 3 switches seamlessly to island mode and keeps your whole home running from solar and battery.
- Tesla app: The best monitoring app in the home battery market — real-time data, Storm Watch, time-based control, SEG optimisation.
- 10-year warranty: Backed by Tesla, a well-capitalised manufacturer with no financial concerns. Warrants 70% capacity retention at 10 years.
Installed cost: £9,500–£10,500 for a single Powerwall 3. Up to 4 units can be stacked. 0% VAT applies.
Best for: Homeowners who want the best available system with no compromises — best app, best backup capability, best long-term manufacturer support. If the budget is there, this is the easiest decision.

4. SolarEdge Home Battery Best for Existing SolarEdge
If you already have SolarEdge solar panels, the SolarEdge Home Battery is the cleanest retrofit option. It integrates natively with the SolarEdge inverter system and requires no additional inverter hardware.
- Native SolarEdge integration: Uses your existing SolarEdge inverter — no additional hardware required if you already have a compatible SolarEdge system.
- 9.7kWh and 19.4kWh options: Available in two sizes, or stacked for up to 38.4kWh.
- mySolarEdge app: Integrates fully with your existing SolarEdge monitoring dashboard.
Best for: Homeowners with existing SolarEdge solar installations who want the simplest, most integrated battery retrofit.
Not ideal for: New installations without existing SolarEdge equipment, or those wanting the most competitive pricing.

What If I Already Have a GivEnergy Battery?
If you have an existing GivEnergy system, here is an honest assessment of your situation:
Your battery still works — for now
The physical hardware is not affected by the administration. Your GivEnergy battery will continue to charge and discharge normally. In the near term, nothing changes from a day-to-day perspective.
Risks to be aware of
- Warranty claims: GivEnergy's product warranties were issued by GivEnergy Ltd. With the company in administration, warranty claims may be difficult or impossible to enforce. Check your original installation contract — your installer's workmanship warranty (usually 2–5 years) may provide some protection.
- Firmware and app: GivEnergy regularly pushed firmware updates that improved performance and fixed bugs. These updates will stop. The GivEnergy app and cloud portal may eventually be taken offline.
- Replacement parts: If a component fails outside warranty, sourcing genuine replacement parts may become difficult over time.
What to do now
For most existing GivEnergy owners, the practical advice is: keep using your system, monitor its performance, and plan for eventual replacement. There is no urgency to rip out a working battery. But if you are planning a solar or battery upgrade in the next 1–2 years, budget for a replacement rather than trying to expand a GivEnergy system.
If you bought GivEnergy through a reputable MCS installer who is still in business, contact them about your warranty position. If your installer was IWA Approved, your deposit and workmanship guarantee were protected by FCA-regulated insurance — contact IWA directly for advice.
IWA protection — check if you are covered
If your GivEnergy system was installed by an IWA Approved Installer, your 6-year workmanship guarantee is backed by FCA-regulated insurance. Visit iwa.biz to check if your installer was registered and to make a claim if needed.
Frequently Asked Questions
The best GivEnergy alternative in 2026 is SigenStor by SigEnergy for most homeowners — it is modular, competitively priced, V2H capable, and backed by a financially stable manufacturer. For a premium experience with whole-home backup, Tesla Powerwall 3 is the clear choice. For budget-conscious buyers, Fox ESS offers the best value.
This is unclear. GivEnergy's product warranties were issued by GivEnergy Ltd. With the company in administration, enforcing warranty claims is likely to be difficult. Your installer's workmanship warranty may provide some protection — check your original paperwork. If your installer was IWA Approved, your workmanship guarantee is backed by FCA-regulated insurance. Check your home insurance policy as well, as some policies cover product failures.
Yes — existing GivEnergy batteries continue to work normally. The hardware is not affected by the administration. The main risks going forward are: firmware updates will stop, the GivEnergy app and cloud portal may eventually go offline, and warranty claims may be unenforceable. For most homeowners, day-to-day operation is unchanged for now.
Fox ESS systems start from around £3,000–£3,500 installed (5kWh). SigenStor starts from £3,500 installed (5kWh) or £4,500 for 10kWh. Tesla Powerwall 3 (13.5kWh) costs £9,500–£10,500 installed. All residential battery installations attract 0% VAT in the UK until March 2027.
No — GivEnergy batteries are proprietary and cannot be mixed with other brands. If you want to expand your storage, you would need to add another GivEnergy battery unit (if any remain available through distributors), or replace the entire system with a different brand. Given the administration, replacing the whole system is the more sensible long-term approach.
