If you are not on benefits you may still be eligible for core Warmer Homes funding under the ECO Flexible Eligibility scheme of the Greater London Authority. You should contact the Mayor’s Warmer Homes Advice Service for further information, and they will be able to tell you if you meet the eligibility criteria.
For the Sustainable Warmth element of the funding you must have a household income of £20,000 or less after income tax, national insurance and rent or mortgage costs.
