The protection of Critical National Infrastructure is something CLD Fencing Systems has been doing for over 40 years with it’s innovative Rigid Mesh Fencing Systems that offer guaranteed delay against attack thanks to being accredited to LPS 1175.


Whether you are working in the Water, Gas, Electric or Nuclear Utilities Industry, our range of permanent and temporary utilities fencing and gate systems will keep your next project secured.


From Security Rated Fencing and Gates, to specially designed and manufactured Non Conductive GRP Isolation Panels and Gates for use on electric sites, every systems comes backed by years of experience in providing the best utilities fencing solutions across the UK.

How does GRP Fencing work for the Utilities Sector?

With electrical conductivity remaining the number 1 risk in the Utilities and National Infrastructure sectors, it goes without saying that good electrical resistance is key when it comes to perimeter fencing at these locations. In most cases, traditional metal fencing will simply not do and so GRP (Glass Reinforced Plastic) fencing is often the sought-after solution. Offering strength and flexibility but most importantly, boasting non-conductivity, frangibility and radio transparency, GRP Fencing such as that we manufacture here at CLD Fencing Systems is crucial.

What are the requirements for Utility & National Infrastructure perimeter fencing?

All perimeter fencing installed at Utility and National Infrastructure sites must be UK Government approved and hold appropriate security ratings. Governed by the CPNI (Centre for the Protection of National Infrastructure), perimeter fencing and gates at these high-risk areas should follow a certain set of requirements, in order to achieve a safe work environment by:

  • Delineating the boundary
  • Deterring intruders
  • Providing a delay to an intruder
  • Acting as a barrier to vehicles
  • Enabling external view through the fence line

Whatever the purpose of your perimeter fencing, it must provide suitable security. It is therefore recommended that perimeter fencing at Utility sites is used in conjunction with other security measures such as CCTV or security lighting for instance. Where possible, there should be a limited number of gates to minimise the number of access points available to potential trespassers.

All perimeter fencing must be regularly reviewed to ensure they remain fit for purpose.

What is the importance of utility fencing?

Utility fencing is of paramount importance not only for maintaining a secure environment but also for a range of other aspects, including:

  • Defining perimeters to highlight the extent of a site or building
  • Defining access points where it is safe to both enter and exit
  • Defining sterile zones
  • Deterring a breach in security
  • Detection of suspicious behaviour
  • Detection of unauthorised intrusions
  • Detecting threats early to allow for appropriate response and verification
  • Delaying how long it takes for an attacker to breach the perimeter
  • Delay or prevent an attack
  • Minimising the impact of an attack

There are a number of reasons why we’re the go-to for GRP utility fencing, so to find out more about how we can help – get in touch with our team today!

A world first…

CLD Fencing Systems are the only manufacturer in the world who are able to offer LPS 1175 SR3 gates in both Sliding and Swing options to the Utilities Industry.


Our range of gate solutions are specifically designed to offer guaranteed delay against attack, allowing you to secure a site and deploy assets and detection technology in the best locations.


What is more, the Lockmaster SR3 is the only Panic Out Emergency Exit Gate to hold a delay of at least 5 minutes against bolt cutters, drills and crowbar attacks, whilst still being able to be used as an emergency utilities exit point for high risk areas.

Keeping the country running…

The danger to life of losing or contaminated utilities is why it is one of the classified Critical National Infrastructures across the UK. For over 40 years, CLD Fencing Systems has helped to keep the country running and safe with its range of Utilities Fencing.

The big four, Electric, Gas, Water and Nuclear have all benefited from being protected by CLD Fencing Systems LPS 1175 range of Utilities Fencing and Gates. However, as the world changes to alternative renewable sources of energy we have developed new systems to provide the right level of protection.

Designing Utilities Fencing systems to protect sites ranging from Solar to Hydraulic Fracturing requires working alongside clients, security consultants and main contractors to make sure the right level of layered protection is provided.

But it isn’t just the big four we work with, from railways to ports, if your next project needs a dedicated level of protection speak with us to find out how we can help to assist you.
