I have a couple of builders for a 10k ish job. One will offer a contract as part of their SOP. The other seemingly isn't.
According to Fair Trading, it's necessary?
I wasn't aware of this when I did another expensive job (aircon) but I haven't had any serious issues with them which might need a contract.
Should I be pushing for a contract for the other builder?
Use the one that offers you the written contract.
