Choosing the Right Lock for Your Home
Your front door lock is the single most important piece of security hardware on your home. Yet many UK homes still rely on basic Euro cylinder locks that can be defeated in seconds. In this guide, our experienced locksmiths break down the best types of door locks available in 2026 and help you choose the right one for your property.
1. Anti-Snap Euro Cylinders — Best for uPVC and Composite Doors
If your home has a uPVC or composite door (as most modern UK homes do), it almost certainly uses a Euro cylinder lock. Standard Euro cylinders are vulnerable to lock snapping — the most common burglary method in the UK.
Why choose anti-snap: Sacrificial break points protect the internal mechanism. The best models include anti-drill, anti-pick, and anti-bump protection too. Brands like ABS, Avocet ABS, Brisant Ultion, and Yale Superior offer excellent protection.
Read our full anti-snap Euro cylinder guide for detailed comparisons.
2. British Standard BS3621 Deadlocks — Best for Timber Doors
For traditional timber doors, a 5-lever mortice deadlock conforming to BS3621 remains the gold standard. Most UK insurance policies require this standard as a minimum. These locks are significantly harder to pick or force than standard 3-lever mortice locks.
Top picks: ERA Fortress, Union 2134, Chubb 3G114. All meet BS3621 and are insurance-approved.
See our BS3621 deadlock guide for more details.
3. Smart Locks — Best for Convenience and Keyless Entry
Smart locks have come a long way and now offer genuine security alongside convenience. The best models for UK homes work with existing door types and don't require complex installation.
Best options for UK homes: Yale Conexis L2, Nuki Smart Lock 4.0, Samsung SHP-DP609. Look for models with Sold Secure or BS ratings.
Our complete smart lock buying guide covers compatibility, features, and what to watch out for.
4. Multipoint Locking Systems — Best Overall Security
Multipoint locks engage hooks, bolts, and rollers at multiple points along the door frame. They're standard on modern uPVC and composite doors and provide excellent resistance against forced entry. If your multipoint lock is failing, see our guide on uPVC door lock problems.
5. Night Latches (Yale-Type Locks) — Best as Secondary Locks
A night latch on its own is not sufficient security, but paired with a deadlock, it provides convenient daily locking. Look for BS3621 rated night latches for best protection. The Yale 89 Deadlocking Nightlatch is a popular choice.
What Lock Do Insurance Companies Require?
Most UK home insurance policies require:
- Final exit doors: BS3621 mortice deadlock or equivalent
- uPVC/composite doors: Anti-snap cylinder meeting TS 007 3-star rating
- Patio doors: Multi-point locking with key operation
Check your policy documents or call your insurer to confirm. Fitting non-compliant locks could void your cover.
