How to Choose a Builder in Cardiff

08 Aug 2026

Cardiff's dense Victorian terraces in Cathays and Roath, the more affluent streets of Pontcanna and Llandaff, and the newer housing further out each suit different builder experience - a specialist in tight terraced extensions isn't necessarily who you want for a Llandaff conservation area project.

Ask about the specific area

"Have you worked on a property like this nearby?" is more useful than a general "do you cover Cardiff?" - genuine local experience means knowing whether a street sits inside a conservation area and how Cardiff Council tends to handle applications for that type of property.

Before you commit

  • Public liability insurance - see the actual certificate.
  • Recent, verifiable reviews - ideally with photos, from contactable customers.
  • A written, itemised quote - labour, materials and provisional sums separated out.
  • Familiarity with Welsh planning rules - worth confirming they understand these differ from England's.

Compare like with like

Give every builder the same written brief. A wide spread between quotes for identical work usually means one has missed something.

Frequently asked questions

How do I know a builder actually knows my part of Cardiff?

Ask whether they've worked on a property like yours nearby - genuine local experience means knowing whether your street sits inside a conservation area and how Cardiff Council handles applications for that property type.

Should a Cardiff builder understand Welsh planning rules?

Yes - it's worth confirming they understand that Wales' planning rules, under the Planning (Wales) Act 2015, differ from England's.
