You're ready to refresh your living room. Maybe you need a carpenter to fit new built-in wardrobes, or a painter to transform your hallway. You find someone on a local directory, they seem friendly, quote looks reasonable. Then work starts and you realise too late that they're not properly insured, they've done shoddy work, or worse, they disappear halfway through the job.
This happens more often than you'd think. Trading Standards received over 20,000 complaints about cowboy traders in 2022, and many cases go unreported because people are embarrassed or don't know where to complain. When you're investing in your home, whether it's a small repair or a full refurbishment, checking legitimacy isn't paranoid. It's sensible.
Before anything else, ask for proof of business registration. In the UK, most legitimate traders operate as either sole traders, partnerships, or limited companies. If they're a limited company, you can check Companies House online in seconds. Type their name and you'll see registration date, filing history, and directors' details. If they won't give you a company number or their details don't match what's on file, walk away.
For sole traders, ask for their tax registration or UTR number. They should have one if they're declaring income to HMRC. A legitimate business won't be cagey about this.
Next, ask where they're based. Get an actual address, not just a mobile number or "based in the area". Visit Google Maps and check if the address exists. You'd be surprised how many cowboys operate from nonexistent locations or use their mate's garage as a fake office address.
This is where many people slip up. You assume if someone's trading, they must have insurance. They don't. Plenty operate without it, banking on the fact that most customers won't ask.
Request proof of public liability insurance. The certificate should show the trader's name, the insurer, the policy number, and the cover amount (usually £1 million to £10 million depending on the trade). Ring the insurance company if you're unsure. They'll confirm whether the policy is active.
If they're handling electrical work, they should be qualified and insured for that specifically. Carpentry on fitted furniture, plumbing, electrics, gas work, all need appropriate qualifications. If someone's doing work outside their stated expertise without proper credentials, that's a red flag.
Never accept an excuse like "I'm too small for insurance" or "it's a cash job so I'll do you a discount without it". That discount isn't worth being liable if something goes wrong on your property.
The best trades have memberships with recognised bodies. A qualified electrician might be registered with NICEIC or the Electrical Contractors' Association. A surveyor or structural engineer might belong to RICS. A plumber could be Gas Safe registered if they work with gas.
You can verify most of these online. Gas Safe register has a public search tool. NICEIC lets you check registered electricians. These aren't fancy marketing claims. They're real accountability.
If someone works with fitted furniture, fitted kitchens, or bespoke wardrobes, they might belong to the Kitchen, Bedroom & Bathroom Specialists Association or similar trade bodies. These memberships mean they've agreed to follow standards and dispute resolution processes.
Ask specifically what qualifications they hold and ask to see them. A Level 3 in carpentry, a City & Guilds in electrics, whatever's relevant to the job. Legitimate traders keep these accessible.
Phone previous customers. Don't just accept names on a piece of paper. Use Google, ask on local Facebook groups, check Trustpilot or Which? Trusted Traders. You're looking for patterns, not one odd review.
If they've been trading for 10 years with consistent positive feedback, that's worth something. If they've just started and have no reviews, that's fine too, but understand you're taking a gamble. If they have loads of complaints about missed deadlines, poor finishes, or not returning deposits, avoid them.
When you call references, ask specific questions. How long did the job take? Were there unexpected costs? Did they clean up after themselves? Would you hire them again? A real customer will give you an honest answer.
A professional tradesperson will visit your property to assess the work properly. If someone quotes over the phone without seeing the job, they're not taking it seriously. Fitted furniture jobs especially need proper measurement and planning.
The quote should be written down. It should include what's included, what isn't, timescales, payment terms, and any guarantees. If it's vague, they're either inexperienced or setting you up for add-ons later.
Check whether they want a large deposit upfront. Some ask 25 to 50 percent on signing, which is fair. If someone wants 90 percent before any work starts, that's suspect. There's too little incentive for them to finish properly.
A good tradesperson will happily provide references, insurance documents, and answers to every question you ask. If they seem annoyed by your questions or evasive, that tells you something.
Sometimes you just feel something's off. They're rushing you to decide. They offer an unbelievably cheap price. They only accept cash. They can start tomorrow but won't commit to finishing by a deadline.
Your gut reaction usually has something to it. You're not being unfair by asking questions or taking your time. This is your home and your money.
A legitimate tradesperson, whether they're a one-person operation or a team, will understand that you need confidence in them. They'll expect you to check them out. The ones who resent being questioned are the ones to avoid.
