How to Choose a Builder in Wales

Wales covers a wide range of towns and cities, including Cardiff, Swansea, Newport and Wrexham, each with its own local council and, often, its own mix of period and modern housing - so the right builder for your project often depends on what kind of property you have as much as what work you need done.

Look for local experience, specifically

A builder who has worked on several jobs in your specific town - rather than just "Wales" generally - will already understand the local council's typical approach to permit applications for skips and scaffolding, common foundation issues in the area's older housing, and which conservation areas apply. Ask directly: "have you done a job like this nearby, or on a similar street?"

Check the basics before anything else

• Public liability insurance - ask to see the certificate, not just be told it exists.
• Recent, verifiable reviews - ideally with photos of similar work, and from customers you could plausibly contact.
• A written quote that breaks down labour, materials and any provisional sums, not a single lump figure.
• Who's actually doing the work - some builders subcontract everything; that's not necessarily a problem, but you should know upfront.

Get more than one quote, on the same brief

Give every builder you approach the same written description of the job, rather than a slightly different explanation each time - it's the only way to compare quotes fairly. A wide spread between quotes for the same brief is usually a sign either the cheapest builder has missed something, or the most expensive one is pricing in more risk than the others - worth asking both why.

Trust, verified

On builderfinder.uk, builder profiles show real completed projects, reviews from people who've actually hired them, and - where the business has been checked - Companies House verification, so you can shortlist builders who cover your town before you ever pick up the phone.
