Nobody thinks about locksmith costs until they’re standing outside their own front door at 11pm with no key. That’s honestly the worst time to be guessing.So here’s a straight answer. Locksmith services in the UK typically cost between £65 and £150 depending on the job type, time of day, and lock complexity. At JW Security, we’ve been doing this work across South London and Surrey since 1991, so we know exactly what fair pricing looks like.
The market has changed a lot over the past decade. More services, more lock types, more variables in pricing, and unfortunately, more rogue traders too. Knowing the numbers upfront puts you in a much stronger position.
What Affects the Price More Than Anything
Before getting into specific figures, it’s worth understanding what actually moves the price around. Because two locksmith jobs that look identical on the surface can come out at very different costs.
The biggest factors are time of day, lock type, and job complexity. A standard lock change during business hours costs significantly less than the exact same job at midnight on a bank holiday weekend.
Standard Hourly Rates Across the UK
During normal working hours, which is roughly 8am to 6pm Monday to Friday, the average locksmith hourly rate in the UK sits around £65. That’s the starting point for most residential call-outs.
After 6pm things shift. Evening rates between 6pm and 8pm typically run around £75 per hour. Between 8pm and midnight you’re looking at roughly £85 per hour. Late-night call-outs after midnight can reach £120 per hour or more, and weekend and bank holiday rates follow similar patterns.
Service-by-Service Cost Breakdown
Different jobs carry different price tags, so here’s what you can realistically expect to pay.
Emergency lockout during daytime hours typically costs between £60 and £120. That covers the call-out and the work to get you back in without damaging the door or lock. A standard Yale lock replacement on a front door runs around £100. Replacing a mortice lock starts from around £137 and rises depending on the brand and security grade required.
UPVC door cylinder replacement tends to sit between £70 and £150 depending on the cylinder grade. Rekeying an existing lock rather than replacing it costs less, usually £59 plus parts in most cases. Key cutting and duplication is the most straightforward service, starting from just £5 for a basic key right up to £20 for more complex cuts.
For context, the average job price recorded by one of the UK’s leading locksmith networks in 2024 came out at £155, covering everything from basic key cutting to multiple high-security lock changes on a single property.
What London Actually Costs
This is genuinely different from the rest of the UK and it’s not just because London locksmiths charge more for the sake of it.
Congestion charges, ULEZ fees, parking costs in central zones, and higher overheads all feed into the final quote. Emergency locksmith rates in London typically start from around £122 per hour during the day, rising to £153 per hour after midnight. So if you’re planning ahead, booking during standard hours saves real money.
If you need reliable locksmith services London property owners actually trust, the key is finding an MLA-approved team that’s transparent about pricing before any work starts, not after.
The Signs You’re About to Get Overcharged
This is important. There’s no government licensing requirement for locksmiths in the UK, which means anyone can call themselves one. That creates real problems.
Watch out for any locksmith quoting an unusually cheap rate on the phone without asking any questions about your door or lock type. The classic “£49” advertised rate is one of the most common setups in the industry, where the headline price balloons once they’re on site. Always ask for a full quote that breaks out the call-out fee, labour rate, parts cost, and VAT separately before agreeing to anything.
Additionally, check whether the locksmith is approved by the Master Locksmiths Association. MLA-approved technicians go through regular inspections, criminal record checks, and maintain insurance cover. That vetting process genuinely matters when someone is working on your locks.
When It’s Worth Spending More
Cheap lock installation from an unqualified tradesperson can leave your property more vulnerable than before the job was done. Incorrect fitting of a euro cylinder, for example, can leave it exposed to snapping attacks, which are one of the most common break-in methods in the UK.
Investing in a British Standard BS3621 compliant lock, fitted correctly by a qualified locksmith, is often a building insurance requirement. Getting it wrong can invalidate a claim entirely.
Final Thoughts
Locksmith costs are genuinely manageable when you know what you’re looking at and who you’re calling. The trap is always the same, cheap quote upfront, big bill at the end.
The team at JW Security offers transparent pricing, MLA-approved workmanship, and over three decades of experience across residential and commercial properties. Whether you need emergency door opening, lock replacement, or a full security upgrade, we provide professional locksmith services London homeowners and businesses have relied on since 1991.
