What is LPS 1175?

LPS 1175 is part of the Loss Prevention Certification Board’s (LPCB) suite of Loss Prevention Standards, widely recognised across the global fire and security industries. This specific standard focuses on the physical protection of building components against forced entry. Among LPCB’s 75+ standards covering various aspects of fire and security, LPS 1175 uniquely addresses the classification and testing of intruder-resistant products such as security enclosures, strong points, and free-standing barriers.

Products evaluated under LPS 1175 include access covers, bars, cabinets, enclosures, cladding, gates, shutters, sliding doors, walls, and windows. Testing also encompasses all integrated hardware—such as locks, hinges, and padlocks—ensuring that the entire product meets the required security resistance.

Importantly, the certification applies to complete systems rather than individual components. Components must be tested separately under relevant LPCB standards to gain individual certification.

Installation methods are also assessed. The product must be mounted onto a substrate with appropriate strength to withstand attack, in line with its intended specification.

How the LPS 1175 Testing Process Works

Testing begins with a product being submitted to LPCB for evaluation. The manufacturer or supplier specifies the target security classification. This classification includes a letter (indicating the toolset used) and a number (indicating the duration of resistance in minutes).

For instance, a product that withstands a 10-minute attack using Toolkit D is classified as D10.

This system allows customers and specifiers to easily understand the level of protection provided and choose products that match their specific security requirements.

LPS 1175 Issue 8: What’s New?

Issue 8 of LPS 1175 introduced major enhancements, offering greater flexibility in how security classifications are defined. Previously, products were grouped under Security Ratings (SR1–SR8). Now, classifications range from A1 to H20, reflecting both the toolset and resistance time more granularly.

Here’s how the new ratings correspond to the older SR system:

• A1 = SR1
• B3 = SR2
• C5 = SR3
• D10 = SR4
• E10 = SR5
• F10 = SR6
• G10 = SR7
• H20 = SR8

This expanded framework allows specifiers to independently select the threat level (toolkit) and resistance time, enabling highly customised solutions. It also supports the use of layered security approaches—combining products with varying ratings to achieve a cumulative delay time. For example, three layers rated C3, C3, and C5 can offer an 11-minute delay against Category C tools.

Issue 8 also introduces scenarios involving multiple attackers for classifications using toolkits F, G, and H, reflecting real-world threats more accurately.

Global Adoption of LPS 1175

Although not a nationally mandated standard, LPS 1175 is widely used across international markets by stakeholders who prioritise advanced protection. Its relevance lies in its focus on deterring unauthorised access attempts involving physical tools—without relying on noise, vehicles, explosives, or firearms.

That said, LPS 1175 is not designed to assess resistance to mass attacks, such as riots. While products certified under LPS 1175 often perform better than those tested to standards like PAS 24, they are not specifically evaluated for the stresses of mob assaults.

For comprehensive protection, physical barriers should be complemented by early detection systems—ideally at the perimeter. Traditional systems like PIR sensors may only activate once an intruder is already inside. Early-warning systems can significantly extend the time available for an effective security response.

Summary of Key Benefits

BRE’s infographic on LPS 1175 Issue 8 illustrates the wide spectrum of security ratings available, supporting diverse security strategies.

Effective protection is not just about physical resistance. It involves a multi-layered approach—delay, detection, response—and projecting a strong deterrent to potential attackers. The perceived difficulty and risk of an attempted breach should outweigh the perceived reward.

LPS 1175-rated products provide robust assurances for the physical resistance of perimeter barriers (fences, gates, turnstiles), façade elements (doors, windows, walls, roofing), and secondary measures (shutters, grilles, cabinets, and enclosures). Certification confirms their capability to delay and deter unauthorised access while supporting detection and response efforts.
