A further 300 Surrey households could get help to make their homes warmer and cut energy bills as part of a “Green Jump Surrey” initiative.
More than 500 Surrey residents have already signed up to the scheme run by energy efficiency service Action Surrey.
Additional funding of £3m from the Government is allowing another 300 households to take part, up to a limit of £15,000 each.
Surrey County Council is also contributing up to £680,000, to allow measures to be fully funded up to the £15,000.
Eligible owner-occupied households can install energy efficiency improvements including loft, solid wall, cavity wall, park home and underfloor insulation.
Air source heat pumps, solar hot water systems and solar photovoltaics can also be funded in addition to insulation works.
Residents could be eligible if they are living in a hard-to-heat home and are in receipt of an eligible means-tested benefit or have a total gross annual household income of less than £30,000.
With the latest funding, the income eligibility criteria have been extended so that those with two or more children, or high housing costs, can have mortgage costs and the number of dependent children taken into account.
Ten of Surrey’s boroughs and districts are taking part, including Reigate & Banstead.
The funding is time-limited. Eligibility can be checked by calling Action Surrey on 0800 783 2503 or using a form on their website.
