What Happens to Your Warranty When the Manufacturer Goes Under

A 25-year or 40-year warranty is only as good as the company still standing behind it, and 2026 gave UK solar and battery buyers two real examples of what happens when that company doesn’t make it.

Two cases from this year

GivEnergy, a UK battery brand, went into administration on 9 April 2026. Maxeon Solar Technologies, the panel manufacturer behind the SunPower Maxeon brand, filed for judicial management in Singapore on 1 April 2026; Nasdaq suspended trading in its stock the following month and formally delisted it in September. Neither company disappeared from UK roofs overnight. Panels and batteries already installed keep working exactly as before, but the warranty behind them is a different question.

What actually happens to the hardware already on your roof

Nothing, mechanically. A battery or panel doesn’t stop generating or storing power because the company that made it is in administration. What changes is who, if anyone, is on the other end of the phone if something fails under warranty. Administration doesn’t automatically void a warranty, but it does mean the business honouring it might now be a successor company, an insurer, or nobody, depending on how the administration or delisting plays out. GivEnergy’s hardware warranties, for example, are no longer being honoured by the company following its administration.

How to actually check before you buy

Ask your installer who backs the warranty, not just what the warranty promises. A manufacturer in good financial health standing behind its own 25-year promise is a different proposition to a warranty underwritten by a separate insurance product, which is worth asking about specifically, since that’s the part that can still pay out even if the manufacturer doesn’t. Our guide to comparing panel and battery brands covers what to check per brand beyond the headline spec sheet.

The bigger pattern

Two insolvencies in one year isn’t a reason to avoid solar or battery storage. It’s a reason to treat “40-year warranty” as a claim worth verifying rather than a number to take at face value, the same way you’d check any other long-term promise from a company you’re about to hand several thousand pounds to.

Frequently asked questions

What happened to GivEnergy in 2026?

The UK battery brand went into administration on 9 April 2026. Existing GivEnergy batteries keep working, but hardware warranties are no longer being honoured by the company.

Is my Maxeon or SunPower panel warranty still valid?

Maxeon Solar Technologies filed for judicial management in Singapore on 1 April 2026 and was delisted from Nasdaq by September 2026. Installed panels keep generating, but check with your installer who's actually standing behind the warranty now rather than assuming the original promise still holds.

How do I check if a warranty will survive if the manufacturer goes under?

Ask whether the warranty is backed by the manufacturer directly or by a separate insurance-backed guarantee. The insurance route is more likely to still pay out if the original company no longer exists.
