Protecting the UK’s utilities with adequate fencing and security measures is critical when it comes to the safe and continual running of the country’s infrastructure. There’s nothing safer for this job than ‘government-approved’ fencing solutions and systems, which hold the appropriate security ratings.

At CLD Fencing, we have more than 40 years of experience in protecting our national – and critical – utilities infrastructure. We use Securus SR1 and Securus AC government-approved fencing, which are innovative rigid mesh systems, proven to provide guaranteed delays against attacks.

These particular systems have been designed and manufactured in line with Loss Prevention Standard (LPS)1175 UK standards, recognised for providing protection to assets from forced entry.

But which utilities are involved in this critical infrastructure network, and why is it is necessary to protect them with fencing?


What are the main utilities used in the UK?

In the UK, we have a number of utilities which are considered critical to the infrastructure of our country. The ‘big four’ are:

  • electric
  • gas
  • water
  • nuclear
  • How important is fencing to protect utilities?

    As utilities are viewed as critical national infrastructure within the UK and a security breach at one of these sites could potentially have serious national security implications, it’s imperative that the fencing and security around utility sites is of the highest quality.

    Your utilities fencing should:

    • precisely define the boundary to the site
    • clearly outline the access and exit sites
    • deter any intruders and breach in security
    • detect early threats to allow for immediate response
    • delay any potential forced entry
    • minimise the impact of an attack
    • act as a barrier to vehicles
    • provide a clear view through the fence line

    You can also review your fencing solutions using the 5 Ds of effective perimeter security to defend assets.

    Working on the ‘onion skin’ principle, the 5 Ds relate to implementing various layers of security – such as fencing, gates and access control – to work together, not only preventing access to your utilities site but also providing you with the time needed to respond quickly and efficiently.

  • The 5 Ds:

    1. Deter

    The first line of deterrence would be to include something visual, to warn off any potential intruders or criminals. These features could include signs attached to the perimeter fencing and strong security lighting.

    In many circumstances, the mere sight of a high security fencing system can deter intruders from attepting to gain access. Specific system selection, security toppers and heights of said fence can act as looming forces to scare off potential threa

    1. Detect

    Motion detectors, CCTV and electronic surveillance/recording systems will enable you to detect anyone encroaching on your site.

    1. Deny

    Denying access to trespassers is essential and this can be achieved by implementing measures such as manned security access points or electronic card swipe systems.

    These systems can be easily used in conjunction with effective access control. It’s easier to deny access or monitor visitors with a high security gate.

    1. Delay

    Interior barriers, road blockers and parking controls can all help to slow down security breaches, giving you time to respond and take the appropriate action.

    1. Defend

    As the final layer, defending your utilities site would perhaps include a security team or intervention from the police. In some cases, your utilities site could be vulnerable to vehicle-borne attack. You would need to ensure hostile vehicle mitigation measures are put in place.

    These may include PAS 68 and IWA 14 certified crash-rated fencing, barriers, bollards and gates.

    Utilities fencing requirements

    Without a doubt, the most important requirement for utilities fencing is that it provides suitable security in line with the specifications of the site you are protecting.

    To have a robust security plan in place, you must firstly undertake a thorough risk and threat assessment, which will then give you some idea of what your utilities fencing requirements are.

    You should also bear in mind that your utilities fencing should be erected with the future in mind, so you don’t have to go to the added expense of replacing it any time soon, ensuring high-value assets are protected to the highest standard.

    The Centre for the Protection of National Infrastructure (CPNI) highlights that all fences and gates should be regularly inspected, to ensure continued fit-for-purpose.

What can CLD Fencing do for you?

As the only manufacturer in the world able to provide LPS 1175 SR3 gates in sliding and swing options to the utilities sector, here at CLD Fencing we have also developed our own range of GRP non-conductive utilities fencing, railings, and gate solutions.

We manufacture all of our solutions to meet requirements set out in UNI EN ISO 9124/04 standards in relation to heat, cold, and moisture-induced ageing tests. Our products also meet the standards in ASTM G1534-06 regarding exposure to UV rays, ensuring your utilities fencing remains fit-for-purpose for years to come.

Our gate solutions are specifically designed to offer guaranteed delay against physical attack, including the Lockmaster SR3 – the first ‘panic out’ emergency exit gate to hold a delay of at least five minutes against bolt cutters, drills and crowbar attacks.

As the first LPS 1175 SR3 security-rated emergency exit gate in the world, the Lockmaster SR3 has been designed for use on high-security / utilities sites.

Helping to keep the country safe with utilities fencing for the last 40 years, CLD Fencing not only provides protection for the ‘big four’ but also works with other services, including railways and ports.
