Same sort of thing happened to me recently. Went and quoted on a flat rewire the flat was being fully refurbished bathroom and kitchen swapping possessions etc. went through everything with the customer cable routes,bonding as services where being moved ,new board location, replace switch fuse and new sub cable, etc. Didn't hear anything back although I had put a half decent price in as a hospital job (was going to use it to keep a few lads busy in between jobs). About 10weeks later get a phone call so pop over all been rewired, plumbed, decorated, carpeted, new kitchen, new bathroom, etc and has the cheek to tell me her dad has rewired it and done the lot but now needs a cert to keep building control off her back. I did have to chuckle when I declined, Cheeky mare! She couldn't understand why I wouldn't give it a cert even after repeatedly telling her why.
