First Facts: What is LPS 1175?

07 July 2025Appears in First Facts

When securing a critical site, how can you be sure your fence will actually stand up to an attack? The answer lies in a specific security benchmark: LPS 1175. Far more than just a label, this standard, developed by the Loss Prevention Certification Board (LPCB), represents a product's proven ability to resist a forced entry. Read on to find out exactly what LPS 1175 is, how the rating system works, and why choosing a certified fence is crucial for guaranteeing the security and compliance of your perimeter.

What is the LPS 1175 Security Fencing Standard?

LPS 1175 is a security standard developed by the Loss Prevention Certification Board (LPCB). It sets out performance requirements and testing procedures for physical security products, such as fencing systems, doors, barriers, and more, to resist forced entry attacks.

The goal of LPS 1175 is to provide a trusted, consistent measure of resistance against forced entry. It helps specifiers, security professionals, and property owners understand how well a product can delay or deter intruders using real-world attack tools and tactics.

How it Works

Products are physically tested against a set of attack scenarios.
Each scenario uses defined tool kits and timeframes to simulate how long it would take an intruder to gain entry.
Products are then rated with a Threat Level (A-H) and an Attack Delay time (1-20 minutes).
For example, a product rated C5 resists a moderate level of attack (Tool Category C) for 5 minutes.

Security Ratings

Products are classified into Security Ratings (SRs) or Threat Levels based on:

The tools used (ranging from simple hand tools to power tools).
The time an attacker is assumed to have.

Example: SR1 / A1 resists opportunistic attacks with basic tools for 1 minute; SR5 / E10 withstands more experienced attackers using heavy-duty tools for 10 minutes.

Why does the LPS 1175 Standard Matter?

Choosing a fence with an LPS 1175 rating helps ensure compliance with security regulations, risk assessments, and insurance requirements. It also provides peace of mind that the perimeter has been tested against credible threats.

Where are LPS 1175 Rated Products Commonly Used?

Government and military facilities
Utilities and critical infrastructure
Data centres and high-security commercial sites
Airports, prisons, and police stations
