tdgeek:How suitable is your house for renting? Does it comply with the new regulations for dry and insulated rentals? Landlords can be up for biggish money if they have sub standard houses, I imagine yours might be good as you live in it
Good question. Double insulation in the roof, but not wall or underfloor insulation, and windows are single-glazed. The reason there's no underfloor insulation is that the sub floor is too tight to get under there and do it, so I don't think getting an exemption for that would be a problem.
We did have some quotes for home ventilation systems a while ago, but opted against it at the time as multiple people who came in to quote commented that the house felt quite dry. It seems the only real benefit would be less window condensation for a couple of month each year.
