Why Change a uPVC Door Lock?
Common reasons include:

Cost Breakdown: Parts, Labor, and Extras
1. Lock Types and Prices
uPVC doors typically use Euro cylinder locks, which vary in price based on security ratings:
- Basic Euro cylinder: £10–£30 (suitable for low-risk areas).
- Anti-snap (3-star Kitemark): £30–£100 (meets insurance requirements).
- Smart locks: £150–£300+ (keyless entry, app-controlled).
Multi-point locking systems (integrated into the door) may cost £100–£400+ if the entire mechanism needs replacing.
2. Labor Costs
Professional locksmith charges typically include:
- Call-out fee: £50–£100 (covers travel and assessment).
- Hourly rate: £30–£60/hour.
- Total estimate: £80–£150 for a standard Euro cylinder replacement. Emergency or after-hours services may cost 20–50% more.
3. DIY vs Professional Installation
- DIY: Costs just the lock price (£10–£100), but requires skill. Risks include improper fitting or voiding warranties. Always measure the cylinder size (e.g., 40/40mm) before purchasing.
- Professional: Recommended for complex systems or high-security locks. Ensures compliance with insurance standards.
Factors Affecting the Cost
- Lock type: High-security or smart locks increase costs.
- Urgency: Emergency call-outs cost more.
- Location: Prices in London/Southeast may be 10–20% higher.
- Door condition: Older doors may need adjustments or repairs.
Choosing a Locksmith: Tips
- Check credentials: Look for MLA (Master Locksmiths Association) affiliation.
- Read reviews: Trustpilot or Google reviews highlight reliability.
- Get quotes: Compare 2–3 estimates to avoid overcharging.
- Ask about VAT: Ensure quotes include taxes.
Is Upgrading Your Lock Worth It?
Investing in an anti-snap Euro cylinder (with a BS EN 1303:2015 rating) can deter break-ins and meet home insurance criteria. Smart locks add convenience but may not suit all budgets.
Average Total Cost Estimate
- Basic lock replacement: £80–£120 (parts + labor).
- High-security upgrade: £120–£200.
- Full multi-point system replacement: £200–£500+.
