How to Choose a Reliable Locksmith in London

Updated 1 February 2026

Why Choosing the Right Locksmith Matters

The locksmith industry in the UK is unregulated — anyone can call themselves a locksmith. This means there are untrained individuals and scam operations advertising locksmith services. Choosing the wrong locksmith can result in damaged doors, overcharging, poor-quality locks, and even security risks. Taking a few minutes to check credentials can save you hundreds of pounds and a lot of stress.

Check Google Reviews

Google reviews are the single best indicator of a locksmith's reliability. Look for a high number of reviews (50+) with a rating of 4.5 or above. Read recent reviews — they should mention fair pricing, professionalism, and quality work. Be cautious of companies with very few reviews or reviews that all appeared at the same time, as these may be fake.

Ask About Call-Out Fees Before They Arrive

One of the most common complaints about locksmiths is unexpected charges. Before booking, ask: Is there a call-out fee? What's the estimated total cost? Is VAT included? Does the price include the lock? A reputable locksmith will give you a clear estimate over the phone. If they're vague about pricing or refuse to quote, find someone else.

Look for a Local Locksmith

National locksmith call centres often appear in Google Ads. They take your call, then dispatch the nearest available person — who may be an inexperienced subcontractor with minimal training. The call centre takes a cut, so the actual locksmith charges more to compensate. A genuine local locksmith knows the area, builds their reputation locally, and has a direct interest in doing good work.

Red Flags to Watch For

Watch out for these warning signs: no fixed business address, they won't give a price estimate, they arrive in an unmarked van, they immediately suggest drilling the lock (rather than trying non-destructive methods first), or they demand cash only. Legitimate locksmiths carry ID, have branded vehicles or uniforms, and accept card payments.

Questions to Ask Before Booking

Ask these questions when calling a locksmith: How long have you been trading? Can I see your ID when you arrive? Do you carry insurance? What's your estimated arrival time? What payment methods do you accept? What guarantee do you offer on your work? A professional locksmith will answer these confidently.
