I've just got a quote from Miller Pattison (via British Gas) to do cavity wall insulation in a 3-bed chalet bungalow (where about 25-35% of it already has some because it's a new extension).
They have quoted £250 basically, plus £45 to fit a vent in the sitting room (required apparently because there is a fireplace). I think I am getting something fairly minor like £25 off from British Gas.
I'm sure I heard that a building like this could be done for something like £125 with the grants available. I know this varies from region to region, but does anyone have any general advice on how to find out if this is the best I can get, or does anyone in Wilts have any specific advice on grants?
By the way, does it seem odd to anyone else to go to all that trouble insulating a house and then punch a dirty great air vent in one room? He hinted that many people gaffer-tape them up when he's left.
