How to spot a fake locksmith before they cost you £600.

Why this matters more than for any other trade

Plumbers are regulated by Gas Safe. Electricians have NICEIC. Builders have FMB and TrustMark. Locksmiths have nothing. There is no statutory register, no licence, no required qualification, and no obligation to carry insurance. The bar to call yourself a locksmith in the UK is buying a set of cheap pick tools online and putting "24/7 LOCKSMITH" on a website.

That regulatory gap is why this trade is overrun with bait-and-switch outfits. They prey on people in distress (locked out at midnight, panicking, unable to research properly) and they rely on the customer not knowing what a fair price looks like. Citizens Advice and Trading Standards receive thousands of complaints a year about locksmith overcharging, but enforcement is weak because there’s no licensing body to revoke a licence from.

The seven warning signs

1. The "from £49" or "from £29" advert

Nobody in the UK profitably operates a locksmith business at £49 a call-out. Diesel, insurance, tools, replacement cylinders, time on standby: the genuine economic floor is around £80 to £100 for a daytime call-out, more out of hours. If the headline price is below that, it is bait. The figure on the website is not the figure you’ll be charged on the doorstep.

2. No fixed-line phone number

Real local businesses have either a landline or a UK mobile that has been the same number for years. Scam call-centre operations route every call through rotating mobile numbers and auto-forwarding services. If the number is a non-geographic 0800, 0844 or 0333 with no business name attached anywhere on the public web, treat it as a red flag.

3. Generic "24 hour locksmith" branding with no business name

A real locksmith will tell you the company name on the phone, and that name will appear on Companies House. Bait-and-switch operators use generic phrases like "London Locksmith Services" or "North London 24/7 Locksmiths" with no specific trading entity behind them. If you ask for the registered business name and they can’t give you one, end the call.

4. Identity not visible on arrival

On arrival a real trader can prove who they are: a printed business card, a quote sheet with the trading name on it, an invoice book matching the company you rang. Bait-and-switch outfits routinely turn up with no documentation at all, because the same operator is working for half a dozen brand fronts that day. Ask for the printed company name on the doorstep. If they cannot produce it, that is the cue to refuse the work.

5. Demanding cash up front, before any work is done

No legitimate trader takes payment before the job is finished. Cash up front is how rogues neutralise card chargebacks: once you’ve handed over £400 in £20 notes, getting it back through legal means is hard. A genuine locksmith takes payment by card, cash or bank transfer on the doorstep, after the door is open. Never up front, never into a personal bank account named anything other than the trading entity.

6. Drilling a perfectly pickable lock

Around 80% of domestic lockouts in the UK can be opened non-destructively by a locksmith with proper picks and time. Drilling is a last resort, not a first option. If a "locksmith" arrives, glances at your lock for under a minute, and announces that drilling is the only way, ask them to attempt picking first. If they refuse, do not let them touch the door. Drilling is a five-minute job that lets the rogue charge for a replacement cylinder at four times its real cost.

7. The price changes between phone and doorstep

This is the single most important test. The price you’re quoted on the phone should be the price written on the receipt. If the trader on your doorstep starts saying "well, I see you’ve got a special lock, that’s an extra £180", stop, ring the original number from your phone in front of them, and ask for written confirmation of the original quote. If they get cagey, they’re running the scam.

How to verify a locksmith is genuine, in two minutes

1. Companies House. Go to find-and-update.company-information.service.gov.uk and search the trading name. A real business will have a company number, a registered office address, a date of incorporation, and filed (or about-to-be-filed) accounts. TT Locksmith’s entry is publicly listed under company number 16953411.
2. Master Locksmiths Association register. The MLA maintains a public list of vetted members at locksmiths.co.uk. MLA membership is a positive signal, but absence is not automatically negative; many honest local traders skip the membership fee. Use it as one signal among several.
3. A real address. Plug the business address into Google Street View. A legitimate trader has a registered address that is either a real residential property, a small commercial unit, or an obvious accountant’s office. Bait-and-switch operations register at virtual office services like Hoxton Mix or rented Mailbox addresses with hundreds of unrelated companies at the same building.
4. Cross-check the phone number. Type the number into Google in quotes (for example "07939 979 445"). If the same number appears on dozens of unrelated locksmith sites under different trading names, it’s a call-centre lead-aggregator, not a local business. If it appears only on one consistent business presence, that’s a real trader.
5. Pricing transparency. Real traders publish their full price table. Scam outfits hide behind "call for a quote". My full price table is published. If a locksmith won’t name a price on the phone before they leave, expect to be ambushed on the doorstep.
6. Reviews on independent platforms. Look on Trustpilot, Yelp UK, Nextdoor and Checkatrade, not just Google. Bait-and-switch operations farm Google reviews aggressively but tend to neglect the more moderated platforms. Read the one-star reviews, not the five-star ones, and look for the same phrases recurring (signs of templated complaints, which usually means real victims).

If you’ve already been scammed

1. Stop the payment. If you paid by card, ring your bank’s 24-hour line tonight and request a chargeback under "service not as described". Provide the phone quote vs the actual charge. Most major UK banks accept these chargebacks routinely on locksmith bait-and-switch.
2. Don’t hand over more cash. If they’re still on your doorstep demanding more, refuse, lock yourself in, and ring 999 if they become threatening. This is rare but it happens.
3. Report to Trading Standards via Citizens Advice on 0808 223 1133. They keep a national database of locksmith complaints and pass evidence to local authorities. Even if your complaint doesn’t lead to action, it builds the dossier.
4. Report to Action Fraud at actionfraud.police.uk. If destruction of your property was involved, this is criminal damage as well as misrepresentation.
5. Document everything publicly. Trustpilot, Yelp, Nextdoor, and any local Facebook groups. Scam outfits spawn new fake business names every few months; your warning helps the next person catch them under the new name.
6. Get a real locksmith to inspect the work. A common after-effect is a wrecked cylinder, a damaged door frame, or a non-functioning lock that "passed" the rogue’s sign-off. Document everything photographically before any further work.

Why this trade looks the way it does in North London

Tottenham, Wood Green, Edmonton, Enfield, Walthamstow and Hackney all have unusually high concentrations of UPVC doors fitted in the 1990s and 2000s, and those doors are now reaching the age where key-stuck calls, cylinder wear and handle-mechanism failures happen regularly. That demand draws scam outfits like a magnet, and it’s why "from £49" leaflets land on every front door in N17 some weeks.

I started TT Locksmith as a direct response to this. The published price table, the named company, the Companies House registration, the doorstep-only payment policy: every one of these is a deliberate inversion of how the scam outfits operate. If you want to confirm the legitimacy of any locksmith in this area, including me, run the seven checks above before you let anyone in.
