By the numbers
Typical yearly generation, per kW of panels
≈1,020 kWh per kWp a year — roughly 5% above the UK average
For every kilowatt of panels, a well-placed Swindon roof generates about this much a year. Your own total depends on roof direction, pitch and shading — the roof check estimates it for your address.
How the sun falls across the year
Sunlight peaks in summer and dips in winter — a system is sized for the whole year, not just the peak. Estimated from PVGIS climate data for your postcode area; a roof survey confirms your exact figure.

Local context
Swindon grew as a Great Western Railway town and has kept expanding, so its roofs span railway-era terraces through to brand-new estates:
Grants & support
Solar and battery installations across the UK are currently zero-rated for VAT until 31 March 2027 — a straight saving on the installed price for every household, with no application needed. In England, ECO4 and the Warm Homes scheme can help eligible lower-income households with energy-efficiency measures through their energy supplier or local council.
Eligibility for grant schemes depends on your income, home and circumstances, and the schemes change. We keep the current picture on one page rather than guess what you'll qualify for.
Common questions
Most domestic installations are permitted development. Swindon's Railway Village conservation area and the old town have listed and protected buildings where visible panels can need consent. A local installer knows the Swindon Borough Council position, and a survey confirms suitability first.
Swindon prices track the UK average. A typical 4 kWp system lands in the £4,800 to £6,800 range installed, with battery storage adding roughly £3,000 to £6,000. Solar and battery are zero-rated for VAT until 2027. The on-roof survey gives the firm figure.
Generally yes. The large modern developments such as Wichelstowe and the north Swindon estates tend to have simple, unshaded pitched roofs that suit a clean panel layout and rarely need consent. Direction and shading still decide the yield, so a survey is worth booking.
This page covers Swindon borough, the town, its western fringe and Highworth (SN1 to SN6, SN25 and SN26). The SN postcode spreads across rural Wiltshire, so Marlborough, Devizes, Calne, Chippenham and Malmesbury are kept separate as their own areas.
