For this house for the last 33 years I have only ever used builders that are personal friends - working on a time and materials basis, after they have given me a ball park price for the job. On a fixed price deal if the builder encounters problems ( of their own making or there is no opportunity to recover additional costs from you, they will likely as not cut corners). Selecting a builder on a lowest quote basis may not always be the cheapest option.
I have always done the Planning / Building regs/structural calcs separately so you have control.
It all depend on how much oversight and project management time you intend to put in. If you are working from home it will be an ideal opportunity to upset the builders from constant supervision:)
