How to Choose a Builder in Cardiff
30 Jul 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.
