Does your door meet the standard your insurer names?

If your final exit door is wooden, this is the line in your policy that matters — and you can check it yourself before calling anyone.

Many home insurers require a British Standard kitemarked lock on wooden final-exit doors. It hides in the small print under “security requirements” or “endorsements” — and a missing kitemark can shrink a claim exactly when you need it most.

• Kitemark on the faceplate. Open the door and look at the metal edge of the lock — British Standard locks carry a stamped kitemark. No stamp, no standard.
• “5 lever” on a mortice deadlock. It should say five levers on the faceplate — the 3-lever locks fitted to thousands of older doors rarely satisfy insurers.
• A night latch alone isn’t enough. A Yale-type latch is convenience, not security — insurers usually want a kitemarked deadlock alongside it.

Not sure what you’re looking at? Send us a photo of the lock’s faceplate — we’ll tell you in minutes what it is and whether it satisfies the wording.

Composite door? Behind that timber-look skin, most composite doors lock with a uPVC-style multipoint mechanism — so gearbox failures and alignment problems belong on our uPVC & multipoint page. If it’s the cylinder or the handles, you’re in the right place — and we’ll point you at the honest fix either way.

Wooden & composite door locks, honestly answered.

Wouldn’t it be cheaper to just replace the whole door?

Almost never. A new composite door, supplied and fitted, costs many times more than even our most thorough lock work — repairing or upgrading the locks on a sound door is a fraction of that. And if the door itself is genuinely beyond saving, we’ll tell you — and we can point you to a joiner we trust, at cost, no referral fee.

Will fitting a mortice lock damage my door?

Not when it’s done properly. Where there’s an existing mortice pocket we reuse it, enlarging only if the new lock truly needs it; a fresh fit is marked out, drilled and chiselled by hand to the size of the lock — no oversized routing, no split stile, dust sheet down. Period doors keep their face and their original furniture.

What’s the difference between a night latch and a deadlock?

The night latch is the Yale-type lock that clicks shut behind you — convenience, held by a spring. The mortice deadlock is the key-operated bolt buried in the door’s edge — the one doing the real security work, and the one insurers care about. Most wooden front doors should have both, and we’ll tell you straight if yours only needs one.

Does my insurance really require a British Standard lock?

Many policies require one on wooden final-exit doors, but not all — the honest answer lives in your policy wording, usually under security requirements or endorsements. We’ll read that section with you before recommending anything; there’s no upsell in fitting a kitemark your policy doesn’t ask for.

My composite door won’t lock — is that this page?

Probably not, and it’s worth knowing why: behind the timber-look skin, most composite doors lock with a uPVC-style multipoint mechanism. If the handle lifts but the key won’t turn, or the door only locks when you lean on it, that’s a mechanism job — our uPVC door locks page covers it. Cylinders, handles and the wooden-door locks belong here.

One door sorted — what about the other ways in?

A calm, door-by-door check of the whole house, with written recommendations ranked by what actually matters. No pressure, no follow-up calls.
