We tested and compared response times of multiple locksmith services across London, including highly-rated providers like Premier Security London, to discover who truly delivers the fastest urgent locksmith response in the city.
The efficiency of job completion, the professionalism of the locksmith, and the ability to handle various lock types also matter significantly.
Average arrival time
Response time consistency
Availability during peak and off-peak hours
Coverage of Greater London

We conducted unannounced tests across Central, North, South, East, and West London, during weekdays, weekends, and overnight hours.
Each scenario simulated a genuine emergency: locked out, broken key, or a jammed lock.
Average Arrival Time: 17 minutes
Fastest Response: 11 minutes (near Holborn)
Slowest Response: 29 minutes (around Southbank during rush hour)
Most Reliable: Companies using GPS-dispatched mobile units
Average Arrival Time: 23 minutes
Common Challenges: Traffic on A406, fewer locksmiths stationed north of the river
Top Performer: Providers offering real-time ETAs via app or SMS
Average Arrival Time: 20 minutes
Peak Hours Delay: Slight increase in the morning (up to 30 minutes)
Notable Detail: 24/7 locksmiths had better coverage in Southwark and Lambeth

Premier Security London markets itself as a top-tier emergency locksmith provider, promising fast, professional, and round-the-clock services.

Job Completion Speed: Excellent – resolved lockouts in 7–12 minutes
Customer Experience: Highly professional, uniformed, with ID displayed
Extra Services: Door frame repair, boarding-up after break-ins, digital lock installations
While their arrival times were not the absolute fastest, their consistency, professionalism, and added services make them a standout choice for those needing more than just entry assistance.
Companies with multiple mobile locksmiths stationed strategically across zones (e.g., W1, N7, SE1) consistently delivered arrival times under 20 minutes.
The best locksmith services offer real-time GPS tracking, similar to Uber. Clients receive accurate ETAs and technician details, improving both safety and satisfaction.
Locksmiths that arrive in fully-equipped vans solve problems faster. Whether dealing with uPVC door locks, mortice locks, or digital entry systems, having the right tools eliminates the need for follow-ups.
A real urgent locksmith response should never come with surprise charges. Clear price brackets (e.g., £59–£89 for non-destructive entry) indicate a professional operation.
Ignoring these signs could result in lock failure at a critical moment, potentially locking you out, or worse, inviting intruders in.
30-minute response time or better
24/7 availability (including holidays)
