SR1 / A1 Security Fencing in London

SR1 / A1 Security Fencing for London

If you are looking for SR1 / A1 security fencing in London, Collinson Fencing welcomes enquiries from businesses, main contractors, facilities managers and security professionals planning commercial or industrial perimeter projects. Based in Laindon, near Basildon in Essex, we take enquiries for fencing projects across London and the wider South East.

Where a project specification requires an LPS 1175 SR1 or A1 classification, it is important to check the exact standard edition, classification, certification and permitted installation configuration. SR1 and A1 should not be treated as automatically interchangeable; confirm the requirement against the project specification. We can discuss your project requirements and the information available for the proposed fencing system.

Whether you are working on a new commercial development, improving an existing site boundary or following a security consultant's specification, please contact us with the site location and details of the required fencing.

What Is LPS 1175 SR1 / A1 Security Fencing?

LPS 1175 is a standard used to assess products against defined attempts at forced entry under specified test conditions. SR1 is a security designation associated with earlier editions of the standard, while A1 is a classification used in the newer Issue 8 system. A1 is commonly associated with the earlier SR1 level, but the classifications are not automatically interchangeable for every product or project. The applicable rating and edition should always be checked against the product's certification.

Classification terminology has changed between editions of LPS 1175. Do not assume that a rating name corresponds directly to a classification in another edition. Check the exact product certificate, applicable standard edition and requirements in the project specification.

Not every mesh, palisade or steel security fence is LPS 1175 certified. Certification applies to the assessed product and its permitted configuration, rather than to a general style of fencing. The proposed system must meet the requirements specified for the project.

Commercial and Industrial Fencing Projects in London

London has a wide range of commercial and industrial premises with different perimeter security requirements. The appropriate fencing system depends on the site's risk assessment, the assets being protected, access arrangements and the security specification.

Projects may include:

• Commercial premises and business parks
• Industrial units and warehouse boundaries
• Distribution and logistics facilities
• Commercial developments with specified security requirements
• Operational sites requiring perimeter protection
• Projects where an architect or security consultant specifies a tested fencing system

These are examples of potential applications, not a claim that every SR1 product is suitable for every site. The specification and product certification should guide the selection.

Choosing the Right SR1 / A1 Security Fence

When planning SR1 / A1 security fencing in London, consider the complete perimeter rather than the fence panels alone. The proposed system needs to suit the site's layout, ground conditions, access points and security objectives, while matching the relevant product certification.

Important considerations include:

• Product certification: Check the exact LPS 1175 classification and the configuration covered by the certificate.
• Fence height and layout: Ensure the proposed system meets the project's specification and site requirements.
• Gates and access points: Consider entrances and gates as part of the overall perimeter design.
• Ground conditions: Account for foundations, gradients and installation constraints.
• Maintenance: Understand the inspection and maintenance requirements of the completed system.

Where an LPS 1175 rating is mandatory, confirm the product certificate, permitted configuration and installation requirements before ordering or installing the system.
