Appointing a builder in Bath
Bath builders spend much of their time on listed and conservation-area property, where stone, lime and joinery skills matter as much as price. Check that a builder has worked on listed buildings before shortlisting.
Property you'll be working with in Bath
Georgian Bath stone terraces and crescents in the centre, Victorian villas on the slopes, and interwar and post-war houses on the outskirts. Steep sites and restricted street access are common.
Planning in Bath
The whole city is a World Heritage Site and much of it is listed or in a conservation area, so materials, windows and roofs are tightly controlled and listed building consent is often needed.
What builders charge in Bath
£2,600 to £3,600 per square metre for a mid-finish extension shell in 2026; stone and lime work and restricted access push listed projects higher.

How to choose a builder in Bath
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 Bath 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.
