Choosing Builders: How to Pick a Contractor Who Delivers

When you start a home extension or a new conservatory, the first big decision is who will actually do the work. Picking the wrong builder can cost time, money, and a lot of stress. Below is a straightforward, step‑by‑step way to narrow down the field and choose a builder you can trust.

Check Credentials and Insurance

Start by looking at the builder’s licences and certifications. In the UK, a reputable builder should be a member of a recognised body such as the Federation of Master Builders (FMB) or have a valid CSCS card. Ask for proof of public liability insurance and employer’s liability coverage – this protects you if something goes wrong on site.

Read Real Reviews and Ask for References

Online ratings are useful, but they can be vague. Ask the builder for at least three recent client references and call them. Real homeowners will tell you how communication was, whether the project stayed on schedule, and if any hidden costs appeared. Look for patterns – multiple people mentioning the same positive or negative points can be a red flag.

Get Detailed Quotes and Compare Scope

A solid quote should list every element of the job: materials, labour, disposal, and a clear timeline. Beware of estimates that are too low – they often hide extra charges later on. Compare at least three quotes side by side, looking not just at price but at what’s included. If a builder can’t explain a line item, ask for clarification before you sign anything.

Don’t forget to ask how they handle changes. A clear change‑order process will prevent surprise costs if you decide to tweak the design halfway through.

Visit Ongoing Sites

If possible, ask to see a current site the builder is working on. You’ll get a feel for site cleanliness, safety practices, and how the crew interacts with the homeowner. A tidy, well‑organized site usually means the builder respects the client’s property.

Ask About Guarantees and After‑Care

Any reputable builder will offer a warranty on workmanship. Find out how long the guarantee lasts and what it covers. Some builders also partner with manufacturers to provide product warranties, which adds extra peace of mind.

After the work is finished, a good builder will do a walkthrough with you, point out maintenance tips, and answer any lingering questions. This post‑project support can save you headaches down the road.

Trust Your Instincts

Finally, go with your gut feeling. If a builder is hard to reach, avoids answering questions, or pushes you to sign a contract quickly, take a step back. A trustworthy contractor will be transparent, patient, and willing to give you time to decide.

Choosing the right builder isn’t rocket science, but it does need a bit of homework. Follow these steps, use the resources on our site, and you’ll be on your way to a smooth, successful build.
