I want to get my attic and walls insulated this year but due to lack of funds, can't afford both. Bascially, I floored the centre part of my attic last year. The insulation guy who looked at my house suggested not going for the Grant as due to regs, it would be more costly to insulate over that part, that or I would have to remove the flooring. Eitherway, it's more costly to put in walkways. This guy suggested insulation the outer portion of the attic and the walls without going for the Grant. I can't afford to fund the whole job right now and was wondering if anyone can tell me if I were just to do one job, which would be more beneficial - to insulate the cavity walls or to insulate the attic.
