We are looking at a listed house. The seller re-covered the roof and the listed building consent required them to use a certain, expensive material.
There is no building regs sign-off and we can't tell whether it is the right material. But the seller has confirmed in writing (via the EA) that it was.
Would that be good enough for you?
Asking this because the seller made it clear during the viewing that they had a relaxed attitude to rules, so we're a bit paranoid that they might have broken some!
