I already have cavity wall insulation, and was lucky to have an unusually large cavity that meant I got more insulation than most.
If I added the correct amount of loft insulation and triple glazed all the windows the property would I be close?
I would love to install heat exchnagers and make the house airtight etc. But I guess this would be very exspensive?
