Swindon has emerged as one of the most active solar markets in Wiltshire, with installation rates accelerating sharply since 2023. The town's predominantly modern housing stock — much of it built during the rapid expansion of the 1980s and 1990s — features simple, south-facing roof designs that are ideal for solar panel installation. Combined with the South West's high solar irradiance levels, Swindon offers some of the best solar economics in the region.
Is Solar Worth It in Swindon?
The short answer is yes — for the majority of Swindon properties. Swindon sits at the eastern edge of the South West region and benefits from solar yields of approximately 960–1,050 kWh per kWp per year. This is marginally below the Somerset and Bristol averages but still well above the national UK average, making Swindon a strong solar location.
At current electricity prices (approximately 24–28p per kWh in 2026), a typical 4.5kWp system in Swindon will generate approximately 4,320–4,725 kWh of electricity per year. Of this, a household that self-consumes around 50% will save approximately £520–£660 per year on electricity bills. When combined with Smart Export Guarantee income (typically £100–£200/year) and battery storage, total annual savings can reach £900–£1,400.

Swindon's Housing Stock and Solar Suitability
Swindon's housing is predominantly post-war semi-detached and detached properties with simple pitched roofs. Areas including West Swindon (Freshbrook, Toothill, Westlea), North Swindon, and the newer Wichelstowe and Kingsdown developments all have housing types that are particularly well suited to solar installation — good roof pitch, minimal shading, and simple installation access.
The older housing stock in the town centre and around the railway village is generally more complex but still suitable in many cases. D&R Energy conducts a thorough roof survey for every property to confirm suitability before committing to any costs.
Grants Available in Swindon
Swindon homeowners can access the same national grants as the rest of England: 0% VAT on solar panels and batteries until March 2027, the Smart Export Guarantee, and — for eligible lower-income households — the Warm Homes: Local Grant (up to £15,000, replacing ECO4 which closed March 2026). Wiltshire Council has also supported solar PV through its Climate Strategy, though direct local grant funding for residential solar is limited.
