Front Door Lock Recommendations

For most timber front doors, insurers expect a nightlatch plus a BS3621 mortice deadlock as a minimum. That means a British Standard deadlock alongside a British Standard nightlatch, both correctly fitted and aligned.

Recommended setups:

• Timber doors: BS3621 5‑lever deadlock + British Standard nightlatch (auto‑deadlocking preferred).
• uPVC/composite doors: well‑aligned multipoint mechanism with an anti‑snap euro cylinder, fitted and sized correctly.

If you want a new front door lock installation or a home lock upgrade service, we’ll advise on cylinders, nightlatches and deadlocks that match your door and insurance terms. For stronger security or smart options, see our security upgrades.

Need an existing lock changed to meet policy wording or after lost keys? Our lock change service handles that with proper key control and tidy finishing.

Call 020 8138 8488 for advice on your specific door type.

Bedroom & Bathroom Door Locks

Bedrooms and bathrooms use different knobset types depending on privacy and safety needs. Choose the function below to match the room and how it’s used.

• Entrance (keyed): Key outside with a thumb‑turn inside. Good for bedrooms needing security or a home office. Ideal for a bedroom lock replacement when you want controlled access.
• Privacy (thumb‑turn): No key, just an internal turn with an emergency release from outside. The standard for bathroom door lock fitting.
• Passage (no lock): Latch only, for kitchens, hallways, or cupboards where locking isn’t required.

If a handle sags or the latch sticks, we can often repair instead of replacing. See our lock repair options for stiff latches, misaligned keeps and loose spindles.

Landlord Lock Change Service

Between tenancies, changing or rekeying locks protects the property and helps meet insurer expectations. It also provides a fresh key set and a clean handover record.

We can:

• Rekey or replace cylinders on exit.
• Supply labelled key sets for tenants and management.
• Document work for your files and advise on BS3621 compliance for timber front doors.

Portfolio quotes and scheduled visits are available for multiple properties. We’re fully insured, used to working to deadlines, and keep disruption low. Start with a call, or book a visit through our lock change service.

Internal Door Lock Fitting

Internal doors benefit from the right hardware for the job. We supply and fit:

• 3‑lever mortice locks for general internal security.
• Sash locks (latch + lock) where you want a handle and key in one set.
• Bathroom privacy locks with an internal turn and emergency release.
• Internal door privacy knobsets for simple, tool‑free privacy.

Whether it’s a home office, a guest room, or a utility cupboard, we’ll match the lock case to your door thickness and furniture, and keep the finish consistent across the house.

Home Lock Maintenance Tips

A little care goes a long way. Use these quick checks to avoid bigger issues later.

• Lubricate cylinders every 6–12 months with a graphite or PTFE spray. Avoid oil‑based sprays that gum up pins.
• If a uPVC or composite door only locks when you lift the handle hard, the door may be misaligned. Early adjustments prevent gearbox wear — we handle this in our uPVC lock repair service.
• Replace or rekey locks after moving in, losing a key, or if a tradesperson kept a copy.
• Watch for signs of wear: keys catching, a spongy nightlatch, handles that won’t return, or screws working loose.
• Don’t force a key. Withdraw it, re‑insert fully, and try gently — forcing can snap the key and damage the cylinder.
• Windows matter too. Stiff handles, failed espags and loose stays should be fixed promptly — see our window lock repair options.
