Hire Builder: How to Choose the Right Builder for Your Project

Thinking about a new extension, a garden room, or a full house rebuild? The first step is finding a builder you can trust. It can feel overwhelming, but breaking the process down into simple steps makes it manageable. Below you’ll get practical advice on where to start, what to check, and how to keep the relationship smooth from day one.

Where to start your search

Start with people you know. Ask neighbours, friends, or family who have recently built or renovated. Personal recommendations cut through the noise of endless ads and give you a real sense of reliability. If you don’t have a direct contact, look at trusted online directories that list builders with verified reviews. Focus on firms that specialize in the type of work you need – a builder who knows conservatories or loft conversions will understand the details better than a general contractor.

Checking credentials and references

Once you have a shortlist, verify that each builder is properly registered with the relevant UK bodies. Look for a valid CSCS card, a membership with the Federation of Master Builders, or any local authority registration. Ask for a list of recent projects and call at least two past clients. A quick phone call can reveal how the builder handled deadlines, budgets, and unexpected issues. If a builder hesitates to provide references, that’s a red flag.

Next, request written quotes that break down labour, materials, and any subcontractors. Compare the numbers, but also compare how detailed each quote is. Vague totals often hide hidden costs that surface later. Ask the builder to explain any line items you don’t understand – a good professional will be happy to walk you through the figures.

Before signing a contract, read the fine print. Make sure the agreement covers the scope of work, timelines, payment schedule, and a clear process for changes. Include a clause that outlines what happens if the builder misses a deadline or the work isn’t up to standard. Having these details in writing protects both parties and sets clear expectations.

During the build, maintain regular communication. A short weekly check‑in can catch small issues before they become big problems. Take photos of key stages and keep a notebook of any decisions made on site. This habit helps you track progress and provides evidence if a dispute arises.

Finally, think about after‑care. Ask the builder what warranty they offer on workmanship and materials. A reputable builder stands behind their work and will address any post‑completion hiccups promptly. By following these steps, you’ll increase the chances of a smooth project, stay on budget, and end up with a space you’re proud of.
