Hello. We are just about to go into contract with our builder and I would appreciate any advice on what type of contract to use and to what level of detail. Our builder has proposed that we use their standard contract which I am wary of. Our self build mortgage provider recommends using a JCT contract which I have been looking at but it's not clear exactly what details and level of detail to incorporate into the contract. We have costings from the builder but they are not detail to the point of which ASH pump will be used, what bricks are to be used, wood cladding material and style of installation..etc etc.. Can anyone help shed some light on what seems to be a minefield.
