My neighbour had it done with a British Gas offer.... wondered whether anyone had any experience to pass on... and also whether anyone views the cost to pay back in a decent period on reduced heating bills?
We recently moved into a 70s built house (6 bedrooms!) and on the few cold days we have had so far since moving, it feels a cold house already....
I am also considering the other things like new windows and loft insulation, which the house also needs.
Thanks, Nick.
