Used BestBuilders to find a loft specialist near Blyth - highest-priced quote actually had the cheapest spec - the breakdown told the story. Builder did the structural drawings and party wall notices in-house. Cash-flow staged in 6 milestones rather than just two big bites. Final bill ยฃ47320. Insurance happy with the structural certificate.
