Planning a home extension is exciting; it adds space, comfort, and value to your property. But choosing the right builder can make the difference between a smooth project and a stressful one. With so many contractors available, knowing what to ask before signing a contract is key. Here’s how to find a reliable builder and avoid common pitfalls.
Check experience and qualifications
Start by asking how much experience the builder has with extensions similar to yours. An experienced builder will understand planning permissions, building regulations, and structural requirements. Don’t hesitate to ask for evidence of qualifications or memberships in recognised bodies, and search for builders near you on Trust A Trader, where traders are vetted and reviewed by real customers.
Ask to see previous work
A reputable builder will be proud to show you examples of completed projects. Ask to see photos or, if possible, visit a current site to see the quality of their workmanship. Speaking with past clients can give valuable insight into how reliable, tidy, and communicative the builder is throughout the process; thoroughly reading reviews can also give you a great insight into how the builder operates and what you can expect from them.
Get multiple written quotes
Never rely on verbal estimates. Request at least three written quotes so you can compare like for like. Be wary of quotes that are significantly cheaper than others; this may mean corners will be cut or additional costs will appear later. A detailed quote should include materials, labour, timeframes, and any subcontractors involved (such as electricians or plumbers).
Clarify planning and permissions
Ask whether planning permission or building control approval is needed for your extension. While smaller extensions may fall under permitted development, it’s always best to confirm before the work starts, as failing to do so could result in expensive complications. A professional builder should be happy to guide you through the process or recommend a reliable architect or surveyor if needed.
Discuss timelines and payments
Agree on a realistic start and completion date and make sure payment terms are clear from the beginning. Avoid paying large sums in advance. Instead, stage payments tied to progress milestones keep both sides secure. Always get a written contract detailing the schedule, cost, and expectations.
Check insurance and warranties
Ensure your builder holds public liability insurance and, ideally, contract works insurance. This protects you and your property should something go wrong. Reputable builders often provide warranties on their work, giving you added peace of mind.
Choosing a builder for your extension is a major decision, but taking time to research and ask the right questions will pay off. By selecting a vetted professional through a trusted platform like Trust A Trader, you’ll ensure your project runs smoothly, stays on budget, and delivers the home you’ve been dreaming of.
