Emergency Lockout Costs
Across London, a standard daytime lockout using non-destructive entry typically costs between £95 and £200. Night-time and weekend call-outs usually run £100–£250, depending on the locksmith and area. These prices assume the lock can be picked or bypassed without drilling. If destructive entry is required (rare), expect to pay more as a new lock will be needed. Some locksmiths charge a separate call-out fee on top — always ask before booking. The more competitive London locksmiths include the call-out in their price.
Lock Change and Replacement Costs
A basic cylinder lock change in London typically costs £120–£250 including labour and the new lock. The lower end of this range is what you'd expect from a local independent locksmith, while national call centres and premium brands push costs higher. A BS3621 insurance-approved mortice lock replacement ranges from £160–£300 before VAT depending on the lock brand and door preparation needed. Multipoint locking systems are more complex — a gearbox replacement starts from around £190 and a full system replacement can reach £300–£500. Premium cylinder brands like Ultion, ABS, or Mul-T-Lock will always sit at the higher end of any range.
Lock Repair Costs
Most London locksmiths include lock repairs within their standard labour charge. If the job runs longer than expected, additional time is typically charged in half-hour increments — expect £25–£50 per extra half hour depending on the company. If the lock is beyond repair, a reputable locksmith will advise replacement and quote the new lock separately rather than charging for a repair that won't last.
Safe Opening and Repair Costs
Safe opening costs vary significantly based on the safe type and method required. Basic key-operated safes start from around £120–£300 across London. Digital and commercial safes typically cost £240–£600 depending on the brand and security grade. High-security safes (grade 4 and above) can start from £500 and go well above £1,000 for specialist work. Non-destructive methods are always attempted first by reputable safe engineers. If a new lock or combination reset is needed afterwards, that's usually quoted separately.
Security Upgrade Costs
Anti-snap cylinders — the minimum recommended standard — typically cost £35–£80 per lock fitted across London. Higher-rated cylinders (1-star to 3-star) range from £50–£120 per lock. Window lock installation runs £30–£70 per lock depending on the type and fitting difficulty. Some locksmiths offer a free property security assessment when you book upgrade work, though others charge a consultation fee. It's worth asking upfront.
What Affects the Price?
Several factors influence what you'll pay: time of day (night and weekend rates are typically 20–50% higher), lock type and brand, whether destructive entry is needed, the number of locks being changed, and your location in London. Central London locksmiths tend to charge more than those in outer boroughs. Reputable locksmiths will always provide a clear quote before starting work. Be wary of companies advertising prices under £50 for a lockout — hidden fees and inflated final bills are common with cheap-looking operators.
How to Avoid Being Overcharged
Always get a quote over the phone before the locksmith arrives. Ask specifically about call-out fees, VAT, and any potential additional charges. Check Google reviews — real customers will mention pricing. Use a local locksmith rather than a national call centre, as call centres often add a middleman fee of £30–£60 that goes straight to them, not the tradesperson. Look for locksmiths with Checkatrade or similar verified memberships, and confirm they carry the locks they might need so you're not charged extra for a second visit.
