Solar in Stowmarket: autumn 2026 update

Three things changed this autumn that matter if you’re weighing up panels here: bills went up again, local installs kept climbing, and DIY plug-in solar became legal.

1. The price cap rose 4% — again

The price cap rose 4% on 1 October to £1,723 a year for a typical home — the fourth winter running above pre-crisis prices — and it resets again on 1 January. For a home in Stowmarket, that maths is direct: a 4 kW roof here makes about 4,242 kWh a year, and every one of those units is one you stop buying at 26.32p — roughly £500–£830 a year kept in your pocket at current rates.

2. Mid Suffolk keeps installing

Installs across Mid Suffolk grew about 30% between 2023 and 2025, and 15.3% of local homes now generate their own power (DESNZ official statistics). That’s not early-adopter territory any more — it’s your neighbours’ roofs quietly paying for themselves.

Suffolk’s council-backed group-buying scheme has put up 32,000 panels and counting — Mid Suffolk is one of the east’s strongest solar areas.

3. Plug-in solar is now legal

Since 27 August 2026, UK households can legally self-install small plug-in solar kits: up to 800W through a standard socket, using approved kits on the ENA type-test register, with a simple online notification to your network operator afterwards. Renters can formally request permission too. It won’t power a whole house, but it’s the cheapest legitimate way into solar yet — our DIY & plug-in guide covers the rules and our tested kit.

Help is still there for eligible households: the ECO4 scheme for eligible homes, plus 0% VAT on panels and batteries UK-wide.
