The Difference Between BS Standard Locks & Regular Locks – Why It Matters for Your Security.

When it comes to protecting your property, not all locks are created equal. At Vastora Group, our locksmiths often see customers surprised by how much difference a British Standard (BS) lock can make — both in terms of security and insurance protection.

Let’s break it down

What Is a BS Standard Lock?

A BS Standard lock, marked with the British Standard Kitemark (BS3621, BS8621 or BS10621), meets rigorous security and durability tests set by the British Standards Institution (BSI).

This certification ensures:

Strong resistance against picking, drilling, and forced entry

High-quality materials designed to withstand years of use

Compliance with most UK home and business insurance requirements

If your insurance policy mentions “locks must conform to BS3621”, this is exactly what they’re referring to.

Regular Locks – The Hidden Risk

Regular, non-BS locks might look the same on the outside but usually don’t undergo any form of testing.

They may:

Be easier to pick or snap

Lack anti-drill or anti-bump protection

Potentially invalidate your insurance if a break-in occurs

In short, while cheaper at first, they can cost much more in the long run.

Why BS Locks Are Worth It

Upgrading to BS-approved locks is one of the simplest ways to improve your property security.

At Vastora Group, we recommend them for:

Front and back doors (BS3621 for mortice or euro cylinders)

Flats and HMOs (BS8621 for keyless internal exit)

Commercial units needing compliance and durability

They’re also ideal for landlords looking to meet insurance and safety obligations.
