What insurers usually require
Most home insurance policies in the UK ask for British Standard BS3621 locks on final exit doors, the doors you leave the house by. On uPVC and composite doors they expect a working multipoint lock and increasingly an anti-snap cylinder. The exact wording varies, but BS3621 is the phrase to look for. Our lock standards explained page covers what BS3621 and the star ratings actually mean.
Why it matters for a claim
If your policy specifies approved locks and you do not have them, an insurer can reduce or refuse a payout after a break-in, even if there is no connection between the lock and how the burglar got in. It is one of the most common reasons a claim gets pushed back, and it is a horrible thing to discover at the worst possible moment. Meeting the standard keeps your cover solid and your mind at rest.
How to check your own policy in five minutes
Open your policy document and search for the words lock, security or BS3621. Look in the conditions, endorsements or warranties section, not just the headline cover, because that is where the requirement usually hides. If it asks for British Standard or approved locks, check your final exit doors for the Kitemark symbol on the faceplate. If you cannot find it, your locks probably do not qualify, and it is worth sorting before you ever need to claim.
Common pitfalls we see
A nightlatch on its own, the simple Yale-style latch, usually does not meet BS3621 unless it is a British Standard rated version, so many front doors fall short without the owner knowing. Old euro cylinders on uPVC doors are another, easily snapped and rarely anti-snap. And a back door or patio door is just as much a final exit door as the front, so it needs to comply too. People secure the front beautifully and leave the patio door on a builder’s basic cylinder.
Tenants, landlords and shared homes
If you rent, your contents policy still expects the doors to meet the standard, so it is worth asking your landlord in writing to confirm the locks comply. If you are a landlord, fitting BS3621 locks protects both your tenants and you, and it is a small cost against a void or a dispute. We are happy to advise either way.

Frequently asked questions
What does insurance approved locks mean?
It usually means British Standard BS3621 locks on your final exit doors, plus a working multipoint lock and ideally an anti-snap cylinder on uPVC doors. Check your policy wording for the exact requirement.
Can my claim be refused over my locks?
Yes. If your policy requires approved locks and you do not have them, an insurer can reduce or refuse a payout after a break-in, even if the lock was not how the burglar entered.
How do I check what locks my policy needs?
Read the conditions, endorsements or warranties section of your policy and search for lock, security or BS3621. Then check your exit doors for the Kitemark symbol.
Does a Yale latch meet the standard?
A standard nightlatch usually does not meet BS3621 unless it is a British Standard rated version. Many front doors fall short without the owner realising.
Do back and patio doors need to comply too?
Yes. Any door you can leave the house by counts as a final exit door, so back and patio doors need to meet the same standard as the front.
I rent my home, whose responsibility is it?
Your contents policy still expects compliant locks, so ask your landlord in writing to confirm the locks meet British Standard. Landlords benefit from fitting them too.
