Winter Home Security: A Simple Check of Your Doors, Windows and Locks

Start with the lock cylinder

Most uPVC and composite doors use a euro cylinder, the part your key goes into. Older, basic cylinders can be vulnerable to a common forced-entry method called lock snapping.

Anti-snap cylinders are designed to resist it. Look for cylinders tested to TS007 3-star or rated Sold Secure Diamond (SS312). Swapping a cylinder is usually a quick job that does not involve changing the rest of the lock.

Lock it properly, every time

On a multi-point door, the hooks and bolts only engage when you lift the handle fully and then turn the key. A door that is just pulled shut is held by the latch alone. Many home insurance policies expect doors to be locked with the key when the house is empty, so check your policy.

Keys and letterboxes

Do not leave keys on a hook or table that can be seen or reached from the letterbox. A letterbox cage or internal guard stops anyone reaching through, and it also helps with draughts.

Windows count too

Ground-floor and easy-to-reach windows should have locking handles, and the keys should be kept somewhere other than in the handle. Check that every window shuts and locks fully. A window that needs a shove to close is often out of adjustment, and the locking points may not be engaging.

A quick winter checklist

• Anti-snap cylinders on front and back doors
• Every door locked with the key, not just pulled shut
• No keys visible or reachable from the letterbox
• Window locks working on every ground-floor window
• Doors and windows closing without force
• Outside lights working at the front and back
