Appointing a builder in Kent

Kent builders handle extensions and whole-house refurbishments across a very mixed housing stock, from Victorian terraces in the towns to timber-framed and ragstone property in the villages. Traditional materials are the main cost variable.

Property you'll be working with in Kent

Victorian terraces and interwar semis in Maidstone, Canterbury and the Medway towns, plus tile-hung, weatherboarded and timber-framed cottages in the Weald where specialist repair applies.

Planning in Kent

The Kent Downs National Landscape and numerous conservation areas apply materials and design conditions, and each district council runs its own householder guidance. Listed timber-framed property needs consent for work most owners assume is routine.

What builders charge in Kent

£2,300 to £3,100 per square metre for a mid-finish extension shell in 2026. Clay tile, lime and oak-frame work sits above those ranges.

How to choose a builder in Kent

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.
