I read that as NO dodgy cash job as its all I've ever done on our property ;) my guy is great though, not a single error ever and owns up to mistakes but he is foreign.
Same here... decent bunch of lads, that pic I posted is as much as we have planned for a weeks work. Same with bathroom, although I spent a fair bit of time deciding on fittings...
The problem with dodgy cash jobs is if something goes wrong you have zero comeback.
OK for smaller jobs, not sure I'd want to do it for something as big as a loft conversion.
A legit builder with a contract drawn up, paying VAT, gives you a degree of protection.
