Best Locksmiths in London
A curated list of London's finest locksmiths, selected for their workmanship, professionalism and customer service.
Buying Guide: How to Choose the Best Locksmith in London
Finding the best locksmiths in London requires more than a quick Google search. This guide walks you through everything you need to know to make an informed decision — from what qualifications to look for, to how much you should expect to pay, to the warning signs that should make you walk away.
London has no shortage of locksmiths, but quality varies enormously. The best locksmiths share certain characteristics: they hold proper qualifications (MLA (Master Locksmiths Association), City & Guilds Locksmithing, DBS checked, Public liability insurance), carry adequate insurance, have a track record of satisfied customers, and communicate clearly from the first phone call to the final invoice.
This guide is updated annually. The businesses featured in our Best Locksmiths in London list have been selected based on direct experience, customer feedback, professional qualifications, and overall reputation. We don't accept payment for inclusion — every business earns their place.
What to Look For
Qualifications & Accreditation
A top locksmith in London should hold MLA (Master Locksmiths Association), City & Guilds Locksmithing, DBS checked, Public liability insurance. These aren't just pieces of paper — they demonstrate that the locksmith has been trained, assessed, and is accountable to a professional body. Always ask for proof.
Insurance
Never hire a locksmith who isn't insured. Public liability insurance of at least £2 million is essential. If something goes wrong — property damage, injury, or faulty work — you need to know you're covered. Ask to see the insurance certificate.
Experience with Your Property Type
London has an incredibly diverse housing stock — from Victorian terraces to modern apartments. The best locksmith for your project will have experience with your specific property type. Ask about similar jobs they've completed in your area.
Reviews & References
Online reviews are useful, but they're not the whole story. Ask the locksmith for references from recent London jobs. A professional locksmith will be happy to put you in touch with satisfied customers.
Communication
From the first enquiry, pay attention to how the locksmith communicates. Do they respond promptly? Do they arrive on time for appointments? Do they explain things clearly? Poor communication early on is a red flag for the project ahead.
Pricing Transparency
The best locksmiths provide written, itemised quotes. Be wary of vague estimates, day rates without a cap, or quotes that seem too good to be true. A professional locksmith will explain exactly what's included and what isn't.

When comparing quotes, make sure you're comparing like for like. A lower price might mean fewer services included, cheaper materials, or a less experienced locksmith. Always ask what's included in the price and what might be extra.
