How to choose a builder in South West England
You appoint a builder once the scope is defined. If you invite builders before the drawings and specification are settled, every quote prices a different job and you cannot compare them.
- Give every builder the same drawings, specification and programme, then compare line by line.
- Check the company at Companies House, and ask how long the team has worked together.
- Visit a current site, not just a finished photo.
- Ask for public liability insurance and, where relevant, a warranty or guarantee.
- Agree a payment schedule tied to stages completed, never a large payment up front.
What builders in South West England typically work on

Common questions
- How many builders should I ask to quote?
- Three is enough, provided all three price the same written scope. More quotes on a vague brief produce a wider spread, not better information.
- Why do quotes for the same job differ so much?
- Usually because they include different work. Compare the inclusions, exclusions and provisional sums before you compare the totals.
