🛡️ Why Mortice Locks & Nightlatches Matter for Timber Doors
Your front door is your first line of defence — but is it actually up to standard? For timber doors especially, having the right locking system in place isn’t just good practice — it’s a British Standard requirement. If your home still relies on a single basic latch or out-of-date lock, you could be at risk without even knowing it.

🔐 The difference between a mortice lock and nightlatch
A mortice lock is embedded into the door and generally operated with a key from both sides. It’s one of the most secure locking methods for timber doors — offering a deep-set bolt that resists force and tampering.
A nightlatch, meanwhile, is mounted on the inside surface of the door. It offers quick access and auto-locking features, ideal for convenience, but it’s best used alongside a mortice for added strength.
📏 What BS3621 means — and why it matters
BS3621 is a British Standard that ensures your lock has passed rigorous testing for burglary resistance. Insurance companies often require it — and if your locks don’t meet the standard, you could risk invalidating your home insurance.
Look for the British Standard Kitemark stamped on the lock faceplate. If you don’t see it, it’s time to upgrade.

Timber doors should ideally be secured using both a 5-lever mortice deadlock and a BS3621-rated nightlatch. This combo helps protect against forced entry, lock manipulation, and other common burglary methods.
If you’re unsure what type of locks you currently have, a quick inspection by a professional can save you a lot of risk down the line.
