How to Choose the Right Mortice Lock for Different Rooms

Mortice locks remain the gold standard for timber door security in British homes. However, not every room requires the same level of protection. Choosing the right mortice lock for each application ensures security without unnecessary expense. Here is Keys4U's room-by-room guide.

Front and Back Doors: Maximum Security

Your front and back doors are the primary entry points and demand the highest security. Install a British Standard BS3621 five-lever mortice deadlock on each final exit door. These locks are tested against picking, drilling and force attacks, and they satisfy virtually all UK home insurance requirements.

For additional security, consider a BS3621 sashlock that combines a deadlock with a latch, allowing the door to close and latch without needing to deadlock it every time. This is convenient for everyday use while maintaining full security when locked.

Bedrooms and Bathrooms: Privacy Locks

Internal rooms requiring privacy but not high security need simpler solutions. A three-lever mortice sashlock or even a tubular latch with privacy function is adequate. Three-lever locks offer basic security suitable for internal doors where forced entry is unlikely and insurance compliance is not required.

For bathrooms, privacy thumb-turn locks allow emergency access from the outside if necessary, a safety consideration especially for households with young children or elderly residents.

Home Offices and Studies

If your home office contains valuable equipment, confidential documents or client data, upgrading to a five-lever mortice lock is wise. Even though it is an internal door, the contents may justify stronger protection than a basic privacy lock provides.

For properties used as business premises, insurance may require specific lock standards on rooms containing business assets. Check your policy requirements and install compliant locks accordingly.

Garages and Outbuildings

Garages and sheds often contain tools, bicycles and equipment that burglars target. A five-lever mortice deadlock on a solid garage door connecting to the house is essential. For standalone outbuildings, a heavy-duty padlock on a hasp and staple or a mortice lock on a reinforced door provides appropriate protection.

Understanding Lever Counts

The number of levers in a mortice lock affects its security:

• Two-lever: Minimal security, suitable for cupboards and wardrobes only
• Three-lever: Basic security for internal doors where privacy is the primary concern
• Five-lever: High security for external doors, meeting British Standard BS3621 and insurance requirements
