UK Security Rated Building Materials – An Explanation


For every business, security is an essential aspect that cannot be overlooked, and depending on the value of the contents, one must source adequate security. The ratings are based on tests that are carried out by the Loss Prevention Certification Board (LPCB), and they issue a Loss Prevention Standard (LPS) for each product they test.

Loss Prevention Security Levels

The following are current LPS levels, along with a description of the test conditions and also the tools used:

  • LPS 1 – An opportunist attack using only physical force and minimal tools.
  • LPS 2 – A determined opportunist attack using tools that offer a mechanical advantage.
  • LPS 3 – A deliberate attempt at forced entry using a wide range of attack approaches.
  • LPS 4 – Multiple experienced attempts at forced entry with a range of standard tools.
  • LPS 5 – Experienced attempts at forced entry using specialist tools.
  • LPS 6 – Professional attempts at forced entries using effective tools.
  • LPS 7 – Determined professional attempts using the best tools available.
  • LPS 8 – Extreme attempts at forced entry using all available equipment, but falling short of using vehicles, firearms, or explosives.

As a guideline, a small retail outlet with low value stock would use LPS 1, while a jewellery store would be looking at LPS 7 or even 8. Of course, many other industries would require something in between, and if you are unsure about the level to choose, just ask the supplier, as they would have a wealth of experience and can advise you accordingly. Many businesses would opt for SR3 security doors, as they offer a more than adequate level of security, and anything above that would not be necessary, and of course, the higher the level, the more expensive the item will be.

List of Tools Used

Each test uses a specific set of tools, which would range from Class A – G, with the former consisting of screwdrivers, wrenches, pliers and other gripping implements, while for Class G, the list of tools used includes concrete chainsaws, diamond tip cutters, and oxy-acetylene cutting equipment. It is generally accepted in the construction industry that these tests are a strong indication of the security properties of a steel door or walling, and this benchmark allows the consumer to accurately assess a product and purchase something suitable for the intended use.

Secure Ventilation

For many experienced commercial burglars, any access point that has ventilation would be an obvious target, mainly because a louvre design would compromise the strength of the steel, yet there are products that are tested to the above levels. This type of screening would be ideal for pumping station, boiler rooms, or heavy plants that house generators, and often the situation demands bespoke solutions.

If your business needs protection, there are online suppliers of security rated doors and screenings, and if you are unsure about the level of protection you need, the supplier would be happy to advise you on all aspects of security.
