Hi all, our builder has offered a £500 discount on some work (£4000 instead or £4500), if we pay cash. I normally prefer the security of paying via bank transfer, but we're on a budget and this discount would make a massive difference. The builder seems legit, we've had recommendations and have gone to view previous jobs, checked out companies house details etc. The work comes with 5 year guarantee. Does this sound OK? Or would you be wary?
