When it comes to securing your home with mortice locks, brand matters. Not all locks are created equal, and choosing a trusted manufacturer can mean the difference between reliable protection and a false sense of security. Having fitted thousands of mortice locks across the UK, our locksmiths have seen which best mortice lock brands consistently deliver quality, durability, and resistance to attack. This guide covers the top door lock brands UK homeowners should consider.
1. Yale
Yale is arguably the most recognised name in home security worldwide. Their mortice locks, particularly the Yale BS 5-lever sashlocks and deadlocks, are British Standard approved and widely trusted. Yale mortice lock products are known for smooth operation, consistent build quality, and excellent availability of replacement parts. They are a safe choice for any homeowner looking for the best front door lock brand.
2. ERA
ERA has been manufacturing locks in the UK for over 180 years. Their mortice range includes high security 5-lever locks that meet BS3621 standards. ERA is particularly popular among locksmiths for the ERA Fortress series, which offers exceptional pick resistance and hardened steel plates to resist drilling. The ERA 5 lever lock is a staple for residential properties. ERA also celebrated a milestone of 500,000 Nightlatch units sold, testament to their enduring popularity.
3. Chubb (now part of Union/Assa Abloy)
The Chubb name carries enormous weight in British security. Their 3G110 and 3K74 mortice locks were once considered the gold standard. While the brand is now part of larger groups, the original Chubb designs remain highly regarded. Union-branded successors continue to offer detainer-based locking mechanisms that provide excellent resistance to manipulation. For Chubb lock replacement, Union-branded equivalents are the direct successors.
4. Union (Assa Abloy)
Union is a professional-grade brand favoured by locksmiths for commercial and high-security residential applications. Their 2134E and 2234E 5-lever mortice locks are BS3621 certified and built to withstand sustained attack. Union locks are known for precise engineering and long service life. They are a top choice among insurance approved lock brands.
5. Asec
Asec offers excellent value without compromising security. Their Asec 5-lever mortice deadlocks and sashlocks are BS3621 approved and popular for both residential and light commercial use. Asec locks are a go-to choice for landlords and property managers who need reliable high security door locks at competitive prices.
6. Briton
Briton is another Assa Abloy brand that focuses on robust, dependable locks. Their mortice deadlocks are particularly popular in commercial settings but work equally well in residential properties. Briton locks are known for their heavy-duty construction and anti-saw bolts that make forced entry significantly harder.
7. Legge
Legge has been part of the Allegion group and offers a solid range of mortice locks at mid-market prices. Their Legge 5-lever locks are widely available and well-reviewed by locksmiths for their consistent performance. They are a reliable choice for standard residential applications.
8. Securefast
Securefast is a British manufacturer known for value and compliance. Their BS3621 mortice locks offer good security at lower price points, making them popular for rental properties and budget-conscious homeowners.

9. ISEO
ISEO is an Italian brand that has gained traction in the UK for its precision engineering. Their mortice locks feature smooth mechanisms and high-quality materials. ISEO is particularly strong in the master keying and keyed-alike systems, making them popular for blocks of flats and commercial properties.

Best known for their padlocks, Abus also produces a smaller but respected range of mortice locks. Their focus on innovation and materials science results in locks with excellent wear resistance and anti-pick features. Abus is a brand to watch as they continue expanding their UK presence among British Standard lock brands.
What to Look for in a Mortice Lock Brand
Regardless of brand, always verify these three things when choosing the best mortice lock brands for your home:
- BS3621 or TS007 certification for insurance compliance
