Refurbishment and demolition work
Extensions, loft conversions, rewires and full strip-outs all disturb building fabric. A refurbishment and demolition survey is intrusive and should be scoped to the works — a single bathroom and kitchen strip-out does not need the whole house opened up, and the quote should say so.
Contractors will normally ask for the report and register before mobilising, so it is worth instructing the survey once the scope of works is settled rather than the week work is due to start.
