Utilities fencing


Keeping the UK’s critical services protected

The risk of ‘danger to life’ of losing or contaminated utilities, is why the sector is classified as one of the  ‘Critical National Infrastructures’ across the UK. Protecting Critical National Infrastructure is something that CLD Systems has been helping to do for over 50 years. 

Whether it’s water, gas, electric, nuclear or renewables, our range of permanent and temporary fencing will keep your next project secured.


From Security-rated fencing and gates, to specially designed and manufactured non-conductive GRP isolation panels and gates, every CLD System comes backed by years of experience in providing the best physical security systems for the utilities sector.

We have frameworks in place across the UK, meaning CLD can offer the perfect fencing system for your utility site, on either a permanent or temporary basis.

The main four utilities: gas, electric, water, and nuclear have all benefited from being protected by products supplied by CLD Systems, including permanent and temporary solutions. And, as the world changes to renewable sources of energy, our research and development team is also focused on delivering ever more sustainable solutions. We also ensure our products meet the latest security challenges, both during the construction and operational phases of a site.

Utilities FAQs

Electrical conductivity remains the number 1 risk in the Utilities and National Infrastructure sectors. So, it goes without saying that good electrical resistance is key when it comes to perimeter fencing in such environments.

In most cases, traditional metal fencing will simply not do. In fact, GRP fencing (Glass Reinforced Plastic) is often the sought-after solution. The GRP solution offers strength and flexibility but most importantly, it boasts non-conductivity. It is frangible and offers radio transparency. GRP Fencing that we manufacture at CLD Systems is therefore crucial.

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

  • Delineating or indicating the boundary
  • Deterring any potential intruders
  • Providing a delay to any intruders
  • Acting as a barrier to vehicles
  • Enabling external view through the fence line

Whatever the environment your perimeter fencing is in, it must provide suitable security. It is recommended that perimeter fencing on Utility sites is used in conjunction with other security measures. This can include CCTV or security lighting. Where possible, there should be a limited number of access points to the site. As this minimises the points available to possible trespassers ad intruders.

All perimeter fencing must be regularly reviewed to ensure it remains fit for purpose.

Utility fencing is of the utmost importance for maintaining a secure environment. But it also has other benefits:

  • Defining perimeters which identify the size of the building or site
  • Defining access points, where authorised personnel can enter and exit the site
  • Defining sterile zones
  • Deterring a breach in security
  • Detecting any suspicious activity
  • Detecting any unauthorised intruders
  • Detecting threats early allows for the appropriate response and verification
  • Delaying intrusion for any unauthorised personnel
  • Delaying and preventing an attack
  • Minimising the impact of an attack
