I have a semi with a suspended ground floor wood boards. When I was under the house the other day, I noticed none of the central heating pipes where lagged. Can I do this? Should I do this?
If the answer is yes, can I use basic B&Q type pipe insulation with duct tape? Is this the quickest/cheapest/best solution?
Also when I had the cavity wall insulation done, half of the air bricks under the house were blocked. Should I unblock all of them?
