Why Choose British Standard Locks in Leeds?

British Standard locks- are designed to meet strict safety and performance criteria, offering a higher level of security for your home or business. Recognised by insurance providers, these locks are tested against forced entry techniques such as drilling, picking, and snapping. Look for the BS3621 or BS8621 kitemark, which guarantees compliance with UK security standards.

BS- Night Latches

British Standard Night Latches – Extra Security for Your Doors

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, 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. 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.

BS-Mortice Locks

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. 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 in Leeds, we supply and install a wide range of BS-approved locks across Leeds. Stay secure—choose locks that meet the British Standard.

Frequently Asked Questions BS Locks:

Do I need British Standard locks for my home insurance?

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.

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.

Can you upgrade my locks on the same day?

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

What’s the cost of upgrading to British Standard locks?

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.

Will a BS 3621 Lock Reduce my Insurance?

Most home insurance won’t offer cheaper insurance for BS3621 locks though as this is usually a standard requirement. Again we recommend checking with providers to see if having your locks to meet this standard will reduce your cost of insurance.

What Are British Standard Locks?

British standard locks meet rigorous requirements set out by the British standard Institution (BSI) to ensure resistance against common burglary techniques like drilling, picking, and forced entry. The most common standards include:

BS3621: Common for wooden doors with mortice or night latches

BS8621: Internal thumb turn lock – ideal for fire exits

BS10621: External key lock with internal override — added convenience and security

Look for the Kitemark symbol – it proves your lock meets British Standards.
