How to Choose a Builder in Soho

With Soho covered by the City of Westminster's planning rules and a housing stock that ranges from Victorian terraces to newer apartments, 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

Genuine Soho experience - not just "London" broadly - means a builder already knows the practical detail: how the Soho conservation area - Westminster has 57 in total, covering around 78% of the borough restricts what's allowed, typical foundation depth on the older terraces, and how the City of Westminster tends to handle skip and scaffold permits on narrower streets. A direct, useful question to ask is whether they've worked near Carnaby Street and Old Compton Street or on a comparably tight 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, every builder's ID is automatically checked through Noviqent IdCheck, with a manual review by our team as a fallback if anything doesn't come back clean, and their profile shows real completed projects and reviews from people who've actually hired them - so you can shortlist builders who cover Soho before you ever pick up the phone.
