As an insurance expert, I understand the importance of ensuring that your property is protected by high-quality, secure locks. One key standard that many insurers require policyholders to meet is the British Standard BS3621. In this article, we will dive deep into the specifics of BS3621, including the types of locks covered, where they can be used, and how to test their effectiveness. We’ll also guide you through checking if your current locks meet these standards and what steps to take if they don’t.

What is BS3621?

BS3621 is a British Standard that specifies the minimum performance requirements for thief-resistant locks. The standard applies to locks that are typically used on external doors and windows in residential, commercial, and industrial settings. It covers various aspects such as physical security, durability, and key-related security. Locks that meet the BS3621 standard have been rigorously tested for their resistance to common burglary techniques, including picking, drilling, and forced entry.

For further reading on BS3621, you can refer to the official BSI website.

Types of Locks Covered by BS3621

The BS3621 standard applies to several types of locks, including:

  1. Mortice Deadlocks: These are locks that require a key to operate from both the inside and outside. They are commonly used on wooden doors.
  2. Mortice Sashlocks: Similar to deadlocks, these locks also feature a latch operated by a handle, providing additional convenience.
  3. Rim Locks (Nightlatches): These locks are mounted on the surface of the door and usually have a deadlocking mechanism to prevent slipping or “loiding” with a credit card or other flat object.

How to Check if Your Locks Meet BS3621 Standards

To determine if your current locks meet the BS3621 standard, follow these steps:

  1. Look for the kitemark: Locks that adhere to the BS3621 standard will typically display the British Standard kitemark, which is a heart-shaped symbol with the letters ‘BS’ inside it. You should also see the number ‘3621’ printed near the kitemark.
  2. Check the lock’s features: Ensure that your lock has the following features, as required by the BS3621 standard:
    • A minimum of five levers (for lever-operated mortice locks)
    • Anti-picking mechanisms
    • Hardened steel plates or rollers to resist drilling
    • A bolt throw of at least 20mm into the door frame
  3. Consult a professional locksmith: If you’re unsure whether your locks meet the BS3621 standard, consult a professional locksmith who can assess your locks and provide expert advice.

What to Do If Your Locks Don’t Meet BS3621 Requirements

If your locks fail to meet the BS3621 standard, it’s essential to take action to ensure your property’s security and comply with your insurance policy requirements. Here’s what you can do:

  1. Upgrade your locks: Consult a professional locksmith to recommend and install locks that meet the BS3621 standard. This will not only improve your property’s security but may also result in lower insurance premiums.
  2. Review your insurance policy: Check your insurance policy to confirm whether meeting the BS3621 standard is a requirement. If it is, notify your insurer once you’ve upgraded your locks to ensure your policy remains valid.
  3. Maintain your new locks: Regularly inspect and maintain your new locks to ensure they continue to meet the BS3621 standard and provide optimal security.

In conclusion, understanding and complying with the BS3621 standard is crucial for maintaining your property’s security and meeting your insurance requirements. By checking your current locks against the standard, upgrading them if necessary, and consulting a professional locksmith, you can ensure that your property is well-protected and that your insurance policy remains valid.
