What happens to your battery warranty when the manufacturer fails

The short answer

A home battery does not stop working when the company that made it stops trading. The unit on your wall is self contained. It carries on charging from your solar, carries on discharging into the house, and needs nobody's permission to do either. What ends is the paper. A manufacturer warranty is a contract with a company, so when that company ceases to exist, the cover ceases with it, and a fault that would have been a free replacement last year becomes a bill.

What happened to GivEnergy

GivEnergy was, for several years, the best known domestic battery brand in Britain. Its All in One unit gave 13.5 kWh of usable capacity at a full depth of discharge with 7.2 kW peak output, and its gateway delivered whole home backup with a 20 millisecond switchover, which was competitive kit sold in volume through a large installer network. On 9 April 2026 GivEnergy Ltd entered administration and ceased trading.

• Administration date 9 April 2026, with the company ceasing to trade and all 74 staff made redundant.
• Unsecured creditors were owed more than £17,000,000.
• The administrator's Statement of Proposals, filed in late May 2026, recorded no confirmed buyer for the business.
• No further hardware warranties are being honoured by GivEnergy Ltd.
• The UK Energy Storage Association issued guidance for owners, and the consistent instruction was to go back to your installation team in the first instance.

The warranty on paper had been one of the strongest in the market. Systems installed from 11 September 2023 carried 12 years with unlimited cycles and a 70% capacity retention guarantee. The Gateway 2 hardware carried a separate 15 year term excluding switchgear. Both were real commitments when they were written. Neither survives as a manufacturer promise anyone can now claim against, which is the whole lesson of the episode: a long warranty from a company that does not outlast it is worth less than a shorter one from a company that does.

The three layers of cover, and which one failed

Most homeowners think of a battery as having one warranty. It has three separate layers, written by three different parties, and only one of them was destroyed in 2026. The manufacturer product warranty covers the hardware itself and is a claim against the factory. Your installation team's workmanship guarantee covers the fitting, the cabling and the commissioning, and is a claim against the company that came to your house. An insurance backed guarantee is designed to stand behind that workmanship guarantee if the installing company stops trading. A manufacturer failing takes out the first layer and leaves the other two intact.

What owners should check now

If your installation team has gone as well

This is the harder case, and it is why the insurance backed guarantee layer exists. Dig out the certificate, because it will name the insurer and set out what has to happen to make a claim, including any time limits. Where no such certificate was issued, the practical route is a competent local firm willing to work on the hardware. A battery module is not exotic, and a system that runs is worth maintaining even without a warranty behind it. Checking that whoever you bring in is properly certified matters more than ever, and our guide to checking MCS certification shows how to verify it in a couple of minutes.

How to reduce this risk on your next purchase

1. Ask for the warranty document for the exact model on the quote, dated, rather than a link to a brand page or a comparison site.
2. Ask how long the manufacturer has traded in the UK, who owns it, and where the support operation sits.
3. Weigh the term against the counterparty. Tesla warrants the Powerwall 3 in the UK for 10 years at 80% retained capacity with unlimited cycles for self consumption, time of use and backup. Enphase publishes 15 years or 6,000 cycles on the IQ Battery 5P. Fox ESS publishes 12 years across its EQ range. The right question is not only which number is biggest, but which company is most likely to be there when you claim.
4. Check every box separately. The battery, the inverter, the gateway and any EV charging module can each carry a different term, and the shortest one is your real exposure.
5. Confirm the installation team's workmanship guarantee and any insurance backed guarantee in writing before you sign, because those are the layers that survive a manufacturer failing.
6. Keep cycle limits in perspective. At one full cycle a day, a 6,000 cycle cap is more than sixteen years of use, so the years usually run out before the cycles do and the counterparty question matters more than the cycle count.

None of this makes home batteries a bad purchase. The 2026 collapse removed a promise, not a technology, and the units fitted before it carry on doing the job they were bought for. If you are choosing a system now, our battery storage guide covers capacity, output and backup in detail, and every county page in our coverage area carries a local calculator so you can see what a given size would do on your own usage and tariff. For anything the guides do not answer, the help centre is the fastest route to a straight answer.
