How to check a locksmith is genuine — in about two minutes

Start from the uncomfortable fact: locksmithing is not a licensed trade in the United Kingdom. There is no legal qualification, no compulsory register, and no licence that can be taken away. Someone who has never opened a door in their life can advertise as a locksmith tomorrow, entirely lawfully.

Nobody checks on your behalf. So here is how to check, in the time it takes to boil a kettle.

Check 1 — Is there a real address?

Look at the website footer and the contact page for a street address in London, not a list of forty boroughs “covered”.

A genuine local locksmith has premises, or at minimum a registered trading address. A lead-generation site has neither, because there is nothing to have premises for.

Paste the address into a map. A workshop, a shopfront or a unit is a good sign. A mailbox service shared with eleven other companies is a different signal.

Check 2 — Trade body membership, verified at the source

The main trade association in Great Britain is the Master Locksmiths Association (MLA). Membership is not a legal licence — no such thing exists — but the MLA vets and inspects its members, which is far more scrutiny than the law requires.

The critical step: verify from the association’s side, not the company’s.

A logo on a website is an image file. Anyone can save one. Search the MLA’s own find-a-locksmith directory at locksmiths.co.uk for the company name. If it appears there, the badge is real. If it does not, the badge is decoration.

The same logic applies to every other scheme or accreditation claimed: check on the scheme’s own website, every time.

Check 3 — Is the business real on paper?

For a limited company, search the name on Companies House. It is free and takes thirty seconds.

What you are looking for:

• The company exists and is active, not dissolved.
• How long it has traded. Everyone starts somewhere, but a company incorporated three weeks ago and already dominating search results is worth a second thought.
• A pattern of the same director dissolving and reopening companies in the same trade is a genuine warning sign.

Sole traders will not appear, which is normal and fine — but then checks 1, 2 and 4 have to carry more weight.

Check 4 — Do the reviews behave like real reviews?

Do not count the stars. Read them.

Real reviews name a specific problem, a specific area, and often a specific person. They are spread over months and years. Some are lukewarm. The company replies to the bad ones like an adult.

Manufactured reviews arrive in clusters on the same few days, use the same adjectives, mention no detail you could check, and are uniformly five stars from accounts with no other history.

Look particularly for reviews mentioning that the price matched the quote. That is the thing you actually care about.

Check 5 — The phone call itself

The final check catches everything the others miss, and you already have the script:

“What is the total I will pay, including callout, labour, parts and VAT? Please text me that figure before you set off.”

A genuine locksmith does this routinely. They have priced a thousand lockouts and know what a standard one costs.

The answers that should end the call:

• “The engineer will price it on arrival.”
• “It depends” — with no range offered, twice.
• Any pressure to commit before you have a figure.
• Irritation at being asked to put a number in writing.

On the doorstep

• Ask for identification and the name of the company they work for. Check it is the company you rang. If it is not, ask why before they start.
• Photograph the vehicle, discreetly if you prefer. It is a record.
• Confirm the figure you were texted still stands, out loud, before tools come out.
• Ask whether they intend to drill, and if so, why the lock cannot be opened without damage.
• Keep the old lock and the new packaging. If you paid for a TS007 3-star or Sold Secure Diamond cylinder, the box proves what went into your door.

The three-second version

Real address. Membership verified on the association’s own site. Total price in writing before they travel.

A locksmith who clears all three is very unlikely to be the problem. One who fails all three has saved you the trouble of finding out the expensive way.
