GivEnergy battery after the administration: warranty, support and what to do

Where GivEnergy stands, checked 14 and 28 October 2026

GivEnergy is several companies, and each is in a different position:

Two things follow for anyone with a GivEnergy battery on the wall or in a basket. The battery itself is independent of all this: it charges and discharges without the company or a subscription. What has gone is everything that depended on GivEnergy Ltd standing behind it: warranty claims, spare parts, firmware support and phone support.

What GivEnergy sold

On 14 October 2026 GivEnergy’s own batteries page listed three families: the Giv-Bat 9.5 and Giv-Bat 5.12, both low-voltage LiFePO4 batteries, and high-voltage stackable batteries from 10.2 to 20.4 kWh per stack, rated IP65 with 100% depth of discharge. The product most buyers meant by “the GivEnergy battery” was the All in One, a single unit holding the battery and inverter.

The All in One’s datasheet, from March 2025, gives it 13.5 kWh of usable energy and 100% depth of discharge, in four removable packs. It comes as an AC-coupled 3.6 kW or 6.0 kW unit, delivers 7.2 kW peak and 6 kW continuous when running the home off the grid, is rated IP65 and weighs 173.7 kg. Whole-house backup in a power cut needs GivEnergy’s Gateway, an extra, as our whole-house backup page explains for every brand.

That is a capable specification on paper: 13.5 kWh usable is the same capacity as a Tesla Powerwall 3, and the AC-coupled design is a common choice for retrofitting a battery to existing solar. The questions about a GivEnergy battery in 2026 are not about the hardware.

What the 12-year warranty said

The headline warranty on the datasheet is 12 years. GivEnergy’s warranty overview, correct as of 13 February 2024, set the conditions that went with it:

• Capacity: at least 70% of usable capacity retained over the warranty period.
• Health checks: mandatory performance checks at years 5, 8 and 10.
• Connectivity: the system must stay online. If it is offline more than 10% of the time since installation, the warranty may drop to 12 months.
• Fair use: a limit of 10 MWh for every 1 kWh of stored capacity if the battery is controlled by a third party or used for grid trading; cycles are unlimited for self-consumption.
• Who gives it: GivEnergy Ltd, the company in administration, and the owner must have accepted the licence agreement with GivEnergy Software Limited.

The administrator’s statement of April 2026 says no further hardware warranties will be honoured. The Energy Storage Association says warranties can only be enforced against GivEnergy itself, so owners are likely unable to claim, and Which? reported the same in May. So the years and percentages on the datasheet describe a promise whose maker can no longer keep it. A buyer today is relying on the seller instead.

On the same day, at least one installer review we read still described GivEnergy’s warranty and cycle life without mentioning the administration, and GivEnergy’s own batteries page does not mention it either. A date on a warranty claim is worth checking against 9 April 2026.

The app, the cloud and the subscription

GivEnergy Software, the separate company that runs the app and cloud, announced a paid tier in spring 2026. On its pricing page the free Standard tier gives app access only when your phone is on the same home network as the inverter, with manual scheduling, power flow and battery state of charge. Premium costs £4.99 a month including taxes and fees and adds the web portal, access and control from anywhere, automatic tariff optimisation, historic graphs and reports, and management of multiple systems. The page says Premium covers software only, not warranties or support, and that the hardware keeps working without a subscription.

Two risks sit behind that. The company’s control changed hands in August and it received a strike-off notice in September that Companies House recorded as suspended on 30 September, with its accounts and confirmation statement still overdue, so the cloud is not guaranteed to outlive the year. And automation tied to it, such as tariff optimisation on Agile, would stop if it does. The distributor Midsummer launched a subscription-free app in June 2026, called Smug, which reads the inverter over home Wi-Fi through a £40 display unit; that is one route to local control if you rely on scheduling.

Octopus Flux and a GivEnergy battery

Octopus Flux does not care which brand of battery you have, provided you have solar and a battery and meet its other conditions, so a GivEnergy owner can use the standard tariff. Octopus still lists GivEnergy among the batteries compatible with Intelligent Octopus Flux, where the tariff controls the battery, but that tariff is currently open only to customers who bought solar panels and a battery from Octopus. The Octopus Flux rates page lists what the standard tariff pays in each region.

If you own one

1. Keep your paperwork: the invoice, the MCS certificate, the electrical installation certificate and any network notification. You will need them for a claim and when you sell the house.
2. Contact the installer or supplier first. That is the administrator’s own advice, and a company that sold and installed the system may have obligations to you. If you paid by credit card, you may be able to claim from the card provider under section 75 of the Consumer Credit Act 1974.
3. Write down your settings and schedules while the app still shows them.
4. Do not open, move or diagnose the unit yourself. If you ever see damage, smoke or hear hissing, leave the area and call the fire service.

The GivEnergy administration explainer has the full dated timeline and the administrator’s contact route.

If you are thinking of buying one

Treat a GivEnergy battery as a battery without a manufacturer warranty. Ask the seller in writing what cover they give, for how long, and what happens if the seller itself ceases to trade; ask for the installation to be done by an MCS-certified installer who will register the work. Then price the alternatives, because the price gap may be smaller than the warranty gap. On Octopus’s April 2026 battery-only list, a Fox ESS EVO or Enphase battery is £3,947 for about 5 kWh and £5,336 for about 10 kWh, and a Tesla Powerwall 3 is £7,999, against the official median of £890 per kWh for batteries of 6 to 11 kWh. See the Fox ESS and Enphase pages for their warranties and the conditions that go with them, and compare at least two battery storage quotes for your own home.

If you want an AC-coupled battery to add to existing solar, as the All in One was, ask installers which AC-coupled options they quote and see the AC against DC guide.
