Made to measure, made to comply and made to provide high levels of real physical security against forced attack. The steel doorset is a strong and secure door in quite basic form, but there is an increase in the requirements for steel doorsets used in commercial and residential buildings to conform to specific levels of certified security ratings, all based on independent UK third party testing.
Insurers and building owners are specifying high levels of security all round in 2025 and the doors are an obvious and specific target for any building. Insurance certified, security rated doors are needed to conform to LPS1175 Issue 8 ratings at either B3 (SR2), C5 (SR3) or D5/D10 (SR4) levels more and more in the UK. (issue 7 reference in brackets)
A1 (SR1) level security is almost the basic format these days in any security related door
Secured by Design and PAS24 are also relevant in many applications and for some buildings the European RC ratings are also requested.

Basic Information on Security Door Ratings
The majority of UK buildings using steel doors are requesting security certification under LPCB and LPS1175 ratings. It is the most popular rating system currently and most UK manufacturers have developed doors around this testing and rating system. PAS24 is still quite relevant, but mainly for residential properties and then there are other high security ratings from European standards such as the RC ratings. RC2 for example comes from the European standard EN 1627. It’s used across Europe to test security products like doors, windows, shutters, and grilles.
What is LPS1175?
LPS 1175 is a globally recognised security standard developed by the Loss Prevention Certification Board (LPCB) for testing and certifying intruder-resistant building products and in this case steel doorsets. The LPS1175 standard evaluates a doors ability to resist forced entry by simulating real life break-in attempts with various tools and time taken at different test levels.
The certification provides buyers and specifiers with a measurable 3rd party tested and verified benchmark for steel doorsets. It is also an ongoing auditing system and ensures the manufacturers building the doors do so in exactly the same way every single time. Certified products are listed in the LPCB Red Book Live.
How are LPS 1175 Security Ratings actually Measured?
The standard uses different tool kits and variable attack durations in order to categorise the security rating a product achieves after testing and approval..
Overall the ratings are split into 8 different ratings but for steel doorsets in the majority of cases there are SR1, SR2, SR3 and SR4. Beyond SR4 is extremely high level security and hugely costly with SR1 - SR4 satisfying the majority of clients needs. The latest LPS1175 standard is issue 8 and under this Issue 8 standard the SR references are now more exacting but in effect below are the basic test requirements and categories.
A1 (SR1)
Tool type A, 1 minute attack, max test duration 10 minutes
Opportunist attack using small, easily concealed tools, typically used for domestic and low commercial risks.
B2 (SR2)
Tool type B, 3 minute attack, max test duration 15 minutes
More determined opportunist attack using tools of greater mechanical advantage, typically used for domestic and low commercial risks such as office buildings, schools and small shops.
A1 C5 (SR3)
Tool type C, 5 minute attack, max test duration 20 minutes
Deliberate forced entry using a wide selection of commonly available tools, typically used for higher commercial risks and infrastructure.
D10 (SR4)
Tool type D, 10 minute attack, max test duration 30 minutes
Experienced attempts at forced entry, typically used for high commercial risks and critical infrastructure.
Certisecure and STS202 Burglary Resistance (BR)
The STS 202 rating is another UK security standard to certify products like doors based on their ability to resist a burglary attempt. The scale is from BR1 to BR6 in this case with simulated attacks on the product in question using different tools and time once again for the tests and rating results.

A quick overview:
B1 and BR2
These are lower ratings, designed to resist attacks by opportunistic burglars. Tests at these levels use tools like screwdrivers, pliers, and crowbars, and physical force, with the attackers likely trying to avoid making much noise.
To attain BR1, a product must resist attack for one minute, while BR2 requires three minutes.
BR3 and BR4
These ratings indicate resistance to more determined burglars who are prepared to make noise and take risks. Attack tools in these tests include large hammers, chisels, and axes.
Certification requires resistance for five minutes at BR3 and ten minutes at BR4.
BR5 and BR6
These are the highest ratings and are designed for high-risk, high-security properties.
Tests for these levels use powerful tools, including power tools, and assume attackers are not concerned with noise. Both these test levels will require a product to resist attack for a maximum of ten minutes.
