Free Insulation & Energy Grants in Bristol
Last updated:
Bristol has over 206,000 homes (ONS 2023) and declared a climate emergency in 2018 with a target to be carbon neutral by 2030. EPC Register data shows 30% of recently assessed Bristol properties are rated Band D or below. The city's Georgian and Victorian stone-built terraces are particularly expensive to heat without proper insulation — and three major government grants are currently open.
Bristol declared a climate emergency in 2018 and has set a target to be carbon neutral by 2030. Despite this ambition, around 14% of Bristol households are in fuel poverty, with particularly high rates in areas like Hartcliffe, Withywood, and Lawrence Hill.
Bristol's housing is a mix of Georgian and Victorian terraces in Clifton and Redland, interwar council estates in south Bristol, and post-war social housing. Many of the older stone-built properties have solid walls that are costly to insulate, making government grants particularly valuable in the city.
Similar government-funded energy grants are available in nearby areas including Plymouth, Cardiff and Swansea. Each council sets its own eligibility criteria, so it's worth checking the specific rules for your area.

What happens after you're approved in Bristol?
A qualified assessor visits your home (1–2 hours) to check your walls, loft, windows, and heating system.
Within 1–2 weeks, you receive a report detailing which improvements qualify for funding and your estimated energy savings.
Approved installers carry out the work free of charge. Cavity wall insulation typically takes 2–4 hours, loft insulation is usually done within a day, external wall insulation takes 1–2 weeks for a semi-detached house, and internal wall insulation takes 3–5 working days.
After installation, your property gets a new EPC certificate showing the improved energy rating.
