These high-security locks are commonly required for insurance compliance and provide significantly improved protection against common break-in methods such as lock snapping and forced entry.
Upgrading to British Standard locks is one of the most effective ways to improve the security of your home or business, giving you greater peace of mind that your property is properly protected.
Why Choose British Standard Locks?
British Standard locks are designed to meet strict UK security regulations. If you live in Leeds, upgrading to a BS3621 or TS007 approved lock improves home security, satisfies insurance requirements, and reduces the risk of forced entry.
Insurance Approved & BS3621 Compliant:
Most UK insurance providers require British Standard locks on external doors. BS3621 mortice locks and TS007 3-Star cylinders meet recognised security standards, helping Leeds homeowners stay compliant and protected.
Enhanced Protection Against Lock Snapping & Forced Entry:
Modern British Standard locks (TS007 3-Star cylinders) are built with anti-snap, anti-drill and anti-pick technology. This makes them far more resistant to burglary methods commonly used across Leeds, especially on Upvc and composite doors.
British Standard Night Latches – Extra Security For Your Doors
British Standard Night Latches – Extra Security for Your Doors:
British Standard night latches provide an added layer of security for front doors and wooden entrance doors. Designed to meet recognised UK security standards, they help prevent forced entry while offering convenient everyday locking
British Standard (BS3621) night latches offer a strong layer of security for wooden doors and are highly recommended by insurance companies.
Unlike basic night latches, BS-approved models include reinforced locking mechanisms, anti-drill plates, and a deadlocking function, which means the latch cannot be slipped open from the outside once locked with a key.
Fitting a BS3621 night latch helps protect against forced entry and ensures your property meets modern insurance requirements. They’re ideal for both homes and businesses, offering the convenience of quick locking while providing the assurance of a secure, accredited design.
At 247Locksmiths in Leeds , we supply and fit a range of high-quality BS night latches designed for strength, durability, and peace of mind.
If you’re upgrading your front door security, a British Standard night latch is one of the most effective ways to deter intruders and improve overall door protection.
Standard VS British Standard Night Latches:
While standard night latches provide a basic level of security, they often lack the reinforced features that protect against modern break-in methods.
Most non-BS models can be slipped or forced open using simple tools, making them unsuitable for insurance compliance.
In contrast, British Standard night latches (BS3621 or BS8621) are independently tested for resistance to drilling, picking, and tampering.
BS8621 & Insurance-Compliant Night Latches:
Many British Standard night latches comply with BS8621 regulations, meaning they are key-operated from both sides. They include a deadlocking feature, meaning once locked with a key, the internal latch cannot be retracted from outside.
This greatly improves your property’s overall security rating and is a key requirement for home insurance policies.
Upgrading from a standard latch to a British Standard model gives you the peace of mind that your door meets the latest insurance-approved security standards, helping to protect your home and family around the clock.

Benefits Of British Standard 5-Lever Mortice Locks
When it comes to securing external doors, a British Standard 5-lever mortice lock (BS3621) is one of the strongest and most reliable options available.
Anti-Pick, Anti-Saw, and Anti-Drill Protection:
These locks are built to rigorous security standards and include features such as anti-pick, anti-saw, and anti-drill protection, making them extremely resistant to forced entry.
In comparison, non-BS or 3-lever mortice locks provide only basic internal security and are not usually approved by insurance providers.
A 3-lever lock typically has fewer locking mechanisms and thinner materials, making it easier to manipulate or break open. Non-BS models also lack the hardened steel plates and reinforced deadbolt required for true burglary resistance.
Upgrading to a BS3621 5-lever mortice lock not only meets most home insurance requirements but also gives you peace of mind that your property is properly protected. It’s a worthwhile investment that significantly increases door strength and overall home security.
Upgrading to British Standard locks not only improves protection but may also be a requirement for valid home insurance policies.
At 247Locksmiths, we supply and install a wide range of BS-approved locks across Leeds. Stay secure—choose locks that meet the British Standards.

British Standard Locks.

Yes – most UK home insurance providers require BS3621 locks on external doors. If you’re unsure, we’re happy to check your locks and advise.
Q: How can I tell if my lock meets British Standards?
Look for the British standard Kitemark (a heart-shaped symbol with the BSI logo). We can also confirm it during a home security check.

Absolutely. We carry all common British standard locks in stock and can usually upgrade them in one visit.

It depends on the type of lock, but prices are fair and include a 12-month warranty, no VAT, and no hidden call-out fees.

Euro Cylinder Locks – TS007 3 Star Security, With Built In Anti-Snap Technology
TS007 3 Star Euro Cylinder locks offer the highest level of protection against modern burglary methods such as door lock snapping , drilling, and bumping.
These locks meet the British Standard Kitemark TS007 and are approved by major insurance companies as the recommended standard for Upvc, composite, and aluminium doors.
What is SS312 Diamond?
SS312 is a Sold Secure test specification for lock cylinders. SS312 has 2 main grades: Diamond and Gold.
- SS312 Diamond is the highest grade a lock cylinder can achieve, but is deemed as equivalent to a British Standard Kitemark 3 Star cylinder in terms of building regulations.
- SS312 Gold is equivalent to a British Standard Kitemark 1 Star cylinder, and should be combined with SS301 handles or escutcheons, approved at Bronze or higher.
A 3 Star Euro lock combines anti-snap , anti-pick, and anti-drill technology within a reinforced core design. Even if part of the cylinder is snapped, the lock’s internal mechanism remains secure, keeping your door locked and your property safe.
In contrast, standard, or 1-star cylinders, with no anti-snap protection, offer limited resistance and can often be bypassed in seconds by experienced intruders.
What Types Of Locks Can Be Approved To SS312 Diamond Standard?
Any lock cylinder can be tested to SS312, however currently SS312 Diamond standard is only applicable to Euro Profile Cylinders.
If you have lock cylinder fitted to your front or back door, having a SS312 diamond approved cylinder will ensure you have the highest level of protection.
At 247Locksmiths, we supply and fit a range of high security 3 & 1 Star Euro Cylinders that comply fully with TS007 and British Standards. Upgrading your existing cylinder is a quick, cost-effective way to dramatically improve home security.
