Choosing the right builder in London: 10 questions to ask
Planning building work in London? Choosing the right builder is one of the most important…
Learn moreWe're in Master Builder magazine this month, talking cowboy builders, one tiling job that went badly wrong, and why we think licensing can't wait.
We’re in Master Builder magazine, this time, with Pencil and Brick director Seàn talking about cowboy builders and why we think licensing can’t come soon enough.
We’ve heard plenty of these stories over the years, from clients who’ve had bad experiences before they came to us, and from Seán’s time on the Federation of Master Builders London Board, where dodgy builders come up more often than anyone would like. In the magazine, Seán talks about one particular tiling job that went badly wrong, and cost far more than money. It cost time, and it cost trust. But it’s never just tilers. The same thing plays out across every trade, whenever someone’s hired without any real way of knowing what they’re actually getting.
If you want the full story, and you can find it here: “Ridding of the Rogues”.
Right now, that’s genuinely true. There’s no entry standard, no accountability, and nothing stopping someone who’s been thrown off one job from simply opening up under a different name down the road. Bodies like the FMB and TrustMark hold their members to real standards, but there are only around 7,000 FMB members against a UK builder population many times that size. So most of the market sits well outside any oversight at all.
Because of that gap, homeowners end up carrying all the risk. If it goes wrong, there’s often no one to complain to and no way to get your money back.
A mandatory scheme would raise the bar at entry, so it’s harder for someone with no training or track record to set up shop overnight. It would give homeowners a proper route to redress when work goes wrong, rather than a shrug and a closed Facebook group. And it would help unlock work that’s currently being put off altogether, since a lot of homeowners are simply too nervous to commit without some kind of guarantee they’re hiring the right person.
It’s a case that’s gaining ground too. The FMB has picked up support from MPs across the Commons, helped shape a Private Members’ Bill on the issue, and kept up a steady conversation with government departments about how licensing would actually work in practice. Seán’s part in that campaign, and the standards-first approach he brought over from his years as an architect, is what earned him a seat on the FMB London Board.
Until licensing exists, the job of vetting a builder properly falls on homeowners, and most people have never really been shown how to do that well. So we put together a guide for exactly this free guide: 10 Questions Every London Homeowner Should Ask Before Hiring a Builder. It covers what to look for in a quote, how payments and contracts should be structured, and who’s actually accountable for your project once work starts.
A 2026 study by the FMB and HomeOwners Alliance put a figure on it: lack of trust in builders is costing the UK economy £11.2bn a year, with 19% of homeowners putting off essential work because they can’t find someone they trust to do it.
82% said they’d pay more for a licensed builder, and 68% said licensing would give them more confidence to hire one at all. A separate FMB survey from 2025 found 37% of British adults had hired a builder who turned out to be unreliable or unqualified, at a cost of £14.3bn over five years.
