You may be eligible for energy efficiency and low carbon heating to your home depending on your income, tenure of your property (privately rented or owner occupier), the Energy Performance Certificate rating (needs to be D, E, F or G).
However, there are varying eligibility criteria for different sources of grants, so we would encourage you to call the Warmer Homes Advice Service, who can advise you whether you are likely to qualify for the grant.
Social housing tenants are not eligible apart from shared ownership.
