Why Insurance Companies Require Specific Locks
Insurers assess risk. Properties with weak locks cost more in claims — so they set security requirements.
The Consequence for You
If your locks don't meet the specified standards and you're burgled, your insurer may refuse to pay out — leaving you to cover the full loss yourself. Average Belfast burglary loss: £3,000–£5,000. High-value burglaries: £10,000–£50,000+.
Common Insurance Lock Requirements
BS3621 Mortice Deadlocks
The most widely required lock standard. Tested for resistance to drilling, picking, sawing, and pulling. Deadlocking action — can't be opened with a credit card. Minimum 1,000 key differs.
BS8621 Nightlatches
Similar to BS3621 but designed so no key is needed from inside — ideal for final exit doors. Increasingly required alongside deadlocks on main entrance doors.
5-Lever Mortice Deadlocks
Traditional mortice locks with at least 5 levers. Still a common requirement, particularly on older Belfast properties. Significantly more secure than 2 or 3-lever versions.
Anti-Snap Euro Cylinders
Modern policies increasingly require BS EN 1303 certified anti-snap cylinders. Standard cylinders can be snapped in under 30 seconds — anti-snap versions like the ASEC Vital 6-Pin resist this attack.
What is British Standard BS3621?
BS3621 is the British Standard for thief-resistant locks. To earn this certification, locks undergo rigorous independent testing.
Look for the BSI Kitemark on the lock face — this confirms genuine BS3621 certification.
Anti-Snap Cylinders & Insurance
Cylinder snapping has become so common that many insurers now specifically require anti-snap euro cylinders on UPVC and composite doors.
What Insurers Look For:
Important: If your insurer requires anti-snap cylinders and you have standard ones, a successful cylinder-snapping burglary may result in a rejected claim.
How to Check Your Insurance Requirements
Read Your Policy Documents
Your policy will contain a 'Security Requirements' section. Look for phrases like 'British Standard locks', 'BS3621', '5-lever mortice', 'anti-snap cylinders', or 'BS EN 1303'.
Contact Your Insurer
Call your insurance company and ask: What lock standards do you require? Do you require anti-snap cylinders? Are there additional security requirements?
Check Your Current Locks
Look for British Standard certification marks on your existing locks. Do your euro cylinders have anti-snap protection or BS EN 1303 markings? Not sure? We check for free.
Book a Free Assessment
We'll review your requirements, inspect all external doors, check locks against standards, and give you a clear no-obligation quote for any upgrades needed.
What Happens If Your Locks Don't Comply?
Rejected Burglary Claims
You're burgled. The insurer finds your locks don't meet requirements. Your claim is rejected. You receive nothing.
Reduced Payouts
Even without full rejection, insurers may reduce the payout if security requirements weren't met.
Policy Invalidation
In serious non-compliance cases, insurers may invalidate your entire policy — leaving you completely uninsured.
Renewal Problems
At renewal, insurers may ask for proof of compliant locks. Without it, they may refuse to renew or significantly increase your premium.
