The extension on a house I’m looking at doesn’t have building regs. I called the local authority today for advice (which is the advise on the website to do first) and was told that if the extension is more than 10years old then not to bother with regularisation. And they won’t look at it because it’s too old and would require too much opening up of works. It’s conflicting with all the information I’ve read online. And the surveyor recommended regularisation. Has this happened to anyone else?
