Hi. I am at completion/exchange stage which will happen in next few weeks. Had mortgage valuation survey done, they mentioned to ensure Building Regs were in place. House is 1910 with classic lounge through diner. Current owners dont know anything about it and have offered indemnity insurance which will cover any enforcement action costs but not any remedial action costs. Both my solicitor and the vendors have failed to locate any permission, is it possible that this just doesnt exist? Surveyor agreed building is sound but obvioulsy has to cover himself. What should I do? Get Building Regs in now? Will this cost? Will they want to open up wall etc to check for RSJ etc? Under time pressure as place I am in now goes in Sept so need to get sorted asap. Thanks for any advice or experience.
