Improving your home’s energy efficiency, for example, by adding insulation - is vital to reducing bills, combating the climate crisis, and addressing fuel poverty. Residents have told us that cost is the main barrier to upgrading their home’s energy efficiency, with many expressing a desire for more financial support from the Council. In November 2023, we launched the Energy Upgrade Loan to help.

Energy Upgrade Assessment Requirements

To receive funding, applicants needed a valid Energy Performance Certificate (EPC), and all improvements applied for had to be recommended in one of these energy reports:
