GivEnergy Administration 2026 — Guide for UK Solar Engineers

Last updated 2026-06-13 · For UK solar and battery engineers

What happened

GivEnergy Ltd entered administration on 9 April 2026. Christopher Brooksbank of CB Business Recovery Ltd was appointed administrator. All 35 employees were made redundant immediately. The company ceased trading with immediate effect.

The administration applies to GivEnergy Ltd only. GivEnergy Software Ltd — which runs the app and cloud portal — is a separate legal entity and is not in administration. GivEnergy Commercial Ltd (the commercial and C&I division) also continues to trade.

The financial picture: GivEnergy recorded an operating loss of £6.5m in 2024, down from a £6.2m profit the year before. Around £9m was spent on software development over two years with limited outcomes. Unsecured creditors are owed more than £17m.

Do installed systems still work?

Yes. Installed GivEnergy inverters and batteries operate using locally stored firmware, independent of the company. Solar conversion, battery charging and discharging, and grid export all continue. The Energy Storage Association confirmed: systems should continue to work as normal.

There is no remote kill switch. A running GivEnergy system should be left running.

Field advice: Screenshot or export the current system settings from the cloud portal now — charge schedules, SoC thresholds, export limits. If cloud access later degrades, these can be used to reconfigure a replacement system.

App and cloud monitoring

The GivEnergy app and cloud portal (givenergy.cloud) continue to operate, managed by GivEnergy Software Ltd. As of June 2026 there is no expected impact to app functionality.

From May 2026, GivEnergy Software moved to a paid cloud model. Local control over the home network via the app remains free. Remote access, historical data, and API access (including Octopus tariff integration) moved to a paid monthly subscription.

The long-term funding of GivEnergy Software Ltd remains unconfirmed. Advise technically capable customers about the local monitoring fallback.

Local monitoring fallback — GivTCP: GivEnergy inverters expose a Modbus TCP interface on port 8899. The open-source GivTCP tool integrates this with Home Assistant for full local monitoring and control, independent of the GivEnergy cloud. This continues to work even if cloud services are later wound down.

Warranties

Warranties are not being honoured.CB Business Recovery stated explicitly: "As the Company has ceased to trade, no further hardware warranties will be honoured by GivEnergy Ltd."

Most UK GivEnergy systems are still within their stated warranty period (5, 10, or 12 years depending on product). No official claims process is open from GivEnergy Ltd.

Routes that remain open:

Advise customers to retain all documentation: MCS certificates, serial numbers, warranty registration confirmations.

Fault support

GivEnergy Ltd support lines are closed. No manufacturer technical support is available from GivEnergy Ltd.

Midsummer Energy delisted GivEnergy products following the administration. Contact your distributor account manager for current spare parts availability. Stock is finite and depleting with no restocking.

For fault diagnosis on existing systems, the installer is the primary route. Independent remote diagnosis is available from third-party solar support services.

If a GivEnergy battery fails

GivEnergy batteries communicate with GivEnergy inverters over a proprietary CAN bus protocol. A third-party battery (Pylontech, FoxESS, SolaX, etc.) cannot be substituted directly into an existing GivEnergy inverter. The protocol is incompatible.

If a matching GivEnergy battery can be sourced from remaining distributor stock, like-for-like replacement is the cleanest path. Act early — stock will deplete.

If no GivEnergy battery is available, the realistic path is a full system replacement: new inverter plus new compatible battery from a supported brand.

Adding AC-coupled storage: If the GivEnergy hybrid inverter is still working, an AC-coupled battery (Tesla Powerwall 3, Huawei LUNA, AC-coupled Growatt or Sunsynk) can be added on the AC side without touching the existing GivEnergy system. There is a small efficiency penalty vs DC-coupled, but it avoids a full system replacement.

If a GivEnergy inverter fails

First establish whether the fault is repairable. Some GivEnergy faults are component-level failures (capacitors, relays, fuse, CT clamp, GivHub WiFi module) that can be sourced and repaired without a full inverter swap.

If a matching GivEnergy inverter can be sourced, the existing GivEnergy battery will pair with a same-generation replacement. Verify model and firmware compatibility before ordering.

If no replacement GivEnergy inverter is available, a third-party hybrid inverter (FoxESS, Sunsynk, SolaX, Growatt SPH, Solis) must be paired with a new compatible battery from the same brand. The existing GivEnergy battery cannot be reused with a different-brand inverter.

Key checks when replacing with a different brand: verify MPPT input range matches the existing string configuration; refit the CT clamp for the new inverter; reapply the DNO export limit; submit a new MCS commissioning certificate. Octopus API integration does not carry over — the customer needs a new monitoring setup for the replacement brand.

Alternative brands UK installers are moving to

Following the administration, UK installers have been moving to Solis hybrid inverters with Pylontech batteries, FoxESS, Sunsynk, SolaX, and Growatt SPH. Tesla Powerwall 3 is a premium option for AC-coupled retrofits where the existing system is still operating.

When selecting a replacement, prioritise brands with a long trading history, depth of UK distributor coverage (Segen, Midsummer, BMS, Youless), and an open local API or Modbus interface for Octopus tariff integration.
