Appointing a builder in Surrey

Surrey builders work on larger extensions, basement and garage conversions and high-specification refurbishments, usually on detached houses with good access. Specification, not access, drives the price here.

Property you'll be working with in Surrey

Interwar and post-war detached houses and bungalows on generous plots in Guildford, Woking, Epsom and Esher, plus period property in the villages.

Planning in Surrey

Green Belt covers much of the county and limits extension volumes, the Surrey Hills National Landscape adds design and materials conditions, and each borough publishes separate householder guidance.

What builders charge in Surrey

£2,800 to £3,900 per square metre for a mid-finish extension shell in 2026, and £1,300 to £2,100 per square metre for a full high-specification refurbishment.

How to choose a builder in Surrey

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.

  1. Give every builder the same drawings, specification and programme, then compare line by line.
  2. Check the company at Companies House, and ask how long the team has worked together.
  3. Visit a current site, not just a finished photo.
  4. Ask for public liability insurance and, where relevant, a warranty or guarantee.
  5. Agree a payment schedule tied to stages completed, never a large payment up front.

What builders in Surrey 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.
