I am going to apply for grants for BER, cavity wall insulation, roof insulation and upgrade of a gas boiler and controls. I know what the grant values are , but I am just wondering approx how much all of this work would cost on a 3 bed semi D approx 900sq ft. I want to know if it worth my while applying as I may not be able to afford the work if its too expensive. Also, if anyone knows anyone in Bray that can do this work and is reputable i would appreciate the advice. Thanks.
