Genuinely really chuffed with the level 3 survey we have just had back on a 300 year old house. Doesn't seem like the surveyor has seen any serious or expensive defaults. It's more what he couldnt see. There is a big list of '3, urgent' rated areas, only due to not being able to declare them safe. E.g. oil tank looks in good order but would need a specialist to check hence level 3. Drainage seems fine but should be inspected with CCTV. Roof may not have adequate insulation, and timbers can't be seen to assess for condition, no reason particularly to suggest bad condition, but needs investigation. Electricity has a sticker that says last inspected v recently, but you should get an electrician to inspect for you before purchase to be sure. Etc.
My questions are: is this normal?
How much of the extra trades did you then bring in? (Electrician, chimney specialist, oil specialist, drainage specialist, wood boring insects specialist, and someone to quote for investigating structure of room and options for better ventilating roof have all been mentioned). This will cost a lot and be a lot to arrange. Would you do it all?
Will insurance require it,having been listed as a 3?
