What do you guys think about this. We've had someone come to give us a quote for a new boiler + installation + update of our current plumbing system. He claims to be Corgi registered but won't give us his Corgi number until we've gone ahead on the quote and he says this is normal practice. Is that correct? Sounds dodgy to me, but just wondered if anyone has any experience/knowledge on this sort of thing...
Thanks!
Thanks!
