Grant and funding check across County Durham
We cover 13 towns in County Durham, including Darlington, Hartlepool, Stockton-on-Tees, Durham, Chester-le-Street and more.
Funded schemes in England open and close through the year, so we check what is running now rather than relying on old leaflets. We never charge to check funding for County Durham homes, and we do not pass your details to claims companies.
Building Regulations in England
Filling an existing cavity wall is notifiable building work in England. Either a building notice goes to building control before the work, or the installer self-certifies it through a government-approved competent person scheme such as CIGA's CWISC scheme. The insulation used must also be suitable for the wall it goes into, which is why the survey checks construction, condition and exposure first.
Funding in England
- ECO4, the energy-supplier scheme, has been extended to 31 December 2026 and government has said there will be no successor supplier obligation.
- The Great British Insulation Scheme closed as planned on 31 March 2026.
- Warm Homes: Local Grant supports low-income households in England through councils, and the January 2026 Warm Homes Plan sets out fully funded upgrades for low-income homes, with more detail still being published.

If you do not qualify
On a suitable wall, the Energy Saving Trust says most households recoup the cost of cavity wall insulation within about five years, and installing it in a home is currently zero-rated for VAT. We give a fixed price after a free survey.
