Hi There, Been lurking for a few weeks and have a question for someone in the know.
We bought our BISF house about 6 years ago and realised very quickly that during the autumn / winter it would get very cold (our heating bills were astronomical for that first year) we decided to have the entire house externally cavity walled.
We got planning permission and had everything done correctly (proper foundation work, a DPC layer 2 or 3 bricks up, anchored to the house correctly, concrete lintel by the waste, full insulation in between)
We are now selling the property and the buyers valuation surveyor has come back saying that he wont value the property because the air bricks are in the wrong place (initially he said that he wouldn’t value it because there wasn’t evidence of a certificate (which he refused when I offered it to him when he came round to do the survey) and he said there were no air bricks (of which there are 4 near the kitchen)).
Firstly I haven’t seen any other BISF houses that have an external cavity wall, and secondly where should air bricks in a cavity wall be located?
Thanks for any advice.
