Solar & battery in Stowmarket: the local numbers

Why Stowmarket works for solar

Around 15% of homes in Mid Suffolk already generate their own power — one of the highest rates in Britain. That matters twice: it proves panels work here, and it makes Stowmarket one of the UK’s best places to add a battery to existing solar, because most of those systems went in before home batteries were affordable.

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.

0% VAT applies to panels and batteries UK-wide, and council-backed group-buying rounds in the east have cut install prices further.

What the sums look like

At the current capped electricity rate of 26.32p/kWh (Ofgem, Oct–Dec 2026), a well-sited 4 kW system in Stowmarket producing 4,242 kWh a year is worth roughly £500–£830 a year in avoided imports, depending on how much you use as it’s generated — batteries push you toward the top of that range. Export payments add more on top.
