How to check a London locksmith before you call

Start with the fact that changes everything else on this page.

Locksmithing is not a licensed or regulated trade in the United Kingdom. More precisely, locksmiths are not covered by the Private Security Industry Act 2001 and require no Security Industry Authority licence. The SIA covers door supervisors, security guards and similar roles — not the person you are about to let take your front door apart. The Master Locksmiths Association confirms this directly.

Anyone may lawfully advertise as a locksmith today, with no training, no qualification and no register to be removed from. So “are they licensed?” is not a question that can help you. These are the questions that can.

Check at the source, not in the advert

A trade body logo on a website is a picture. Membership is a fact, and it is checkable on that body’s own register. Look the firm up on the register itself rather than trusting the badge, and look for a real, findable address rather than a postcode area.

This matters more than it used to. The newest reported variant of the overcharging scam is rogue firms impersonating genuine long-established traders, which defeats the usual “they have traded for years” reasoning. Verifying at the source is what survives that.

The full sequence — address, trade body register, the business on paper, whether the reviews behave like real reviews, and the phone call itself — is in how to check a locksmith is genuine, in about two minutes.

The phone call is a test, and it is free

Ask for the total you will pay for the job as you have described it, including callout, labour, parts and VAT. Ask what would make that number change. Ask whether they expect to open the lock without drilling it.

A firm willing to answer all three has told you a great deal. A firm that answers only “from £49” has told you something as well. The bands to compare their answer against are on what it costs.

The signal almost nobody knows to look for

A reputable locksmith will ask you to prove you have the right to be in the property — a driving licence, or a utility bill or bank statement with your name and that address on it.

This is the most useful quality signal in the trade, and it is inverted from what people expect. Being asked for proof is reassuring. A locksmith who will open a stranger’s door without asking anything at all is the warning, because the same indifference tends to show up in the invoice and in the standard of the work.

What they may and may not do, and what you are entitled to do yourself, is set out in what a locksmith may and may not do.

We point at registers, not at firms

We name no locksmiths and recommend none. There is no advertising here, no affiliate arrangement and no sponsorship, and nobody can pay to appear.

That is deliberate. Nearly every other result for these searches is either a locksmith or a site selling your call to one, and a recommendation from a page with a commercial interest in the answer is worth nothing. Pointing you at a register you can check yourself is worth something.
