Other insulation services

[1] British Gas installs in mainland Great Britain only. Free installations are through the Energy Companies Obligation and are subject to assessment, technical survey and eligibility criteria. The funding available is to cover insulation and if needed extra specialist equipment i.e. scaffolding and vents. Some properties require more specialist equipment which can't always be covered so if you need more you have the option to pay the extra. Tenants must seek landlord's permission.
