Hi,
We've just had a quote of £190 to add cavity wall insulation to a 4 bed house. Is it worth having it done? What I mean is will we be able to feel a difference (or see a difference in our fuel bills) or is it just another one of these things that's just not really worth doing but the general public have been convinced is.
What I am hoping it will do is make the house cool down more slowly when the heating goes off - at the minute the house gets freezing cold within an hour.
Thanks, Graham
