We’re considering purchasing a flat which has an EPC rating of D. The EPC says it can be made C, but the first step is to provide cavity wall insulation. To do this I believe we would need the freeholder’s permission. What is the situation regarding the rerquirement to have a rating of C or above from 2025 if the freeholder won’t provide this permission?
The freeholder is the local council, so I doubt they will be in a hurry to upgrade the entire estate. Whereas we would be happy to fund it.
