As a local locksmith, I know that peace of mind at home starts with a secure front door. In the UK, many homeowners rely on the British Standard Kitemark as a trusted symbol of quality and security for their door locks. But what exactly is the Kitemark, and is it important?

The Kitemark is a registered certification trademark operated by the British Standards Institution (BSI), an organisation that sets industry standards across various sectors. When it comes to locks, the Kitemark signifies that a product has undergone rigorous independent testing to meet specific British Standards (BS) for security, durability and performance.

The Importance of the Kitemark

There are several good reasons to choose Kitemark approved locks for your home.

1. Enhanced Security

Kitemark testing puts locks through their paces. It evaluates their resistance to common break-in methods like lock snapping, drilling, and picking. A Kitemark lock offers a significantly higher level of protection compared to an unrated lock, potentially deterring burglars and safeguarding your home.

2. Independent Verification

Unlike many manufacturer claims, the Kitemark signifies a product’s compliance with independent, unbiased testing. This provides homeowners with peace of mind knowing the lock’s security features have been rigorously assessed.

3. Meets Insurance Requirements

Some insurance companies offer better prices or discounts for homes with Kitemark-approved locks. This incentive reflects the reduced risk of break-ins associated with these locks.

4. Durability

Kitemark testing goes beyond just resistance to break-ins. Locks are also assessed for wear and tear, ensuring they function smoothly and reliably over an extended period. This means a longer life for your locks and potentially fewer locksmith call-outs.

5. Standardised Security Levels

The Kitemark system employs a star rating system, typically ranging from 1 to 3 stars. Each star represents a higher level of security achieved through a combination of lock features and their performance during testing.

Look for the distinctive Kitemark logo, a kite-shaped symbol with a BS number embedded within it, on the lock faceplate or packaging. The specific BS standard the lock meets (e.g., BS 3621) might also be displayed.

Popular Kitemark Standards for Locks

  • BS 3621: This is the most common standard for Kitemark locks used on residential doors.
  • TS 007


It is clear that fitting secure locks at home can give you peace of mind as they offer a strong first line of defence against intruders. However, while the Kitemark is definitely a good indicator of lock quality, it’s not the only factor you need to consider. That’s why it is always best to get in touch with a good locksmith for professional advice on choosing the most suitable lock for your door type and budget.
