Appointing a builder in Cambridge

Cambridge builders mainly price rear extensions, loft conversions and refurbishments of Victorian terraces and interwar houses, plus a steady flow of energy-efficiency upgrades. Labour is in demand here, so book further ahead than you would elsewhere.

Property you'll be working with in Cambridge

Gault brick Victorian terraces in Petersfield and Romsey, interwar and post-war housing in the outer wards, and newer estates on the fringes.

Planning in Cambridge

Cambridge City Council applies conservation area control across much of the centre and inner suburbs, with additional design guidance for extensions. South Cambridgeshire handles the villages separately.

How to choose a builder in Cambridge

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.

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.
