Mortice Deadbolts

A traditional and highly secure lock fitted into the door itself. BS3621 mortice locks are the insurance industry’s gold standard for front door security.

Rim Nightlatches

The classic Yale-style latch, surface-mounted and ideal for adding secondary security to timber front doors alongside a mortice lock.

Multipoint Locks

Standard on uPVC doors, multipoint systems lock at three or more points simultaneously, providing much stronger security than a single-point lock.

High-Security Locks

For maximum protection, we fit certified high-security locks with enhanced drill, pick, and bump resistance — ideal for vulnerable properties or commercial use.

Common Reasons

When Do You Need a
Lock Change?

You don’t need to have had a break-in to change your locks. Here are the most common situations where a lock change is the right decision.

🏡

Moving into a new property

You have no idea how many copies of the old keys exist. A full lock change is essential when moving into any new home or flat.

🔑

Lost or stolen keys

If your keys are lost or stolen, your home is potentially vulnerable. A same-day lock change gives you immediate peace of mind.

👤

Tenant or lodger has left

Landlords and homeowners should always change locks when a tenant moves out, regardless of whether keys are returned.

💔

Relationship breakdown

When a partner or family member moves out and you want to ensure only authorised people can access your home.

🔓

After a break-in or attempted entry

Following a burglary or attempted break-in, lock changes are an urgent priority to restore proper security.

📋

Insurance requirements

Many home insurance policies require BS3621-approved locks. We can upgrade your existing locks to meet insurer specifications.
