We are buying a house with a garage extension but apparently no building regulations consent for the extension. I have been advised to take out an indemnity insurance to cover prosecution, but we are worried about buildings insurance. Do we have to declare this fact to the insurers that the garage was built without builidings regulation consent? The garage looks fine, I think it's safe and everything, but I am thinking of potential problem when we come to selling the house. Any advice will be appreciated.
