Security fencing is only effective if specified and installed correctly.

Security fence height plays a crucial part in this process.

There are many factors to get right when considering fence height, from understanding the level of protection required, to adhering to local guidelines on security fence height.

The height of your security fence not only affects the aesthetic appearance of the property, but it is also paramount in determining it’s effectiveness in delaying successful intrusion.

This blog aims to explore the importance of correctly specifying your security fence height to ensure it is as efficient as possible.


The Role Of Security Fence Height


Companies specify security fences to act as perimeter security for their premises. Perimeter security’s main objective is to prevent theft, trespassing, hostile vehicle access and other criminal activity.

A security fence that is too low can be The dangers of this can be detrimental to your business. A fence height that is too low can make your site vulnerable to security breaches, affecting property, assets and the safety of individuals.

An incorrectly specified security fence can also damage the reputation of your business. In the event of an intrusion, the resulting fallout draws unnecessary attention to your business and could highlight your poor security measures to the community and/or industry.

Therefore, efficiently specifying your security fence height is a crucial cog in your overall security system.


How Security Fence Height Impacts Design


Although the height of a security fence will mainly influence the level of protection it provides, design is also a factor to be considered.

In our previous design blog that delves into the colour of fencing and how this impacts specification, we explain the importance of design to your site. Check it out here.

A fence that is too high can restrict or block the view of the surroundings areas from your site. Additionally, this can have a negative impact on those passing by, if the fence becomes an eyesore. A fence that is too high will struggle to blend in with its surroundings, regardless of the colour or style of the fence.

Specifying the right fence requires a balance between functionality and design, that complies with local regulations. An efficient security fence will work as a deterrent for intruders.



How Location Can Determine Fence Height


Weather is something that all fence specifiers need to take into consideration.

It is advisable for all fence contractors and specifiers to have wind load calculations done to determine the foundations for the fence structure. For example, wind loading calculations may determine that foundations need to be larger in windy locations.

Locations that are affected by high winds, such as those near the coast or on a hill, will need to consider their fence structure to ensure it is safe.

Are any advertisements going to be affixed to the security fence? This could add to the sail effect and ultimately create a risk for personal and property safety. Furthermore, this may compromise the security of the site, as they may act as foot holds to make climbing the fence easier.


Regulations And How They Affect Fence Height


It’s crucial to make sure that your fence adheres to local regulations in order to avoid penalties and complications during planning permission.

In the UK, a fence over the height of 2 metres will require planning permission. There are factors that can affect this application such as:

  • The site is near a protected area such as an EU-protected site
  • The fence is going to be close to public land (a fence near a public footpath needs permission if it is to be over 1.8m)
  • The fence requires lighting that could affect neighbouring residents


Site owners, security managers, security consultants and anyone else in charge of security should consult local planning authorities in the first instance to establish the relevant planning requirements.

They must submit a planning application where required, providing detailed site plans, specifications, and design requirements. It is vital to ensure the planning application complies with the local planning laws’ strict requirements to avoid claims of infringement or legal disputes.

Of course, this element can affect the type of fence you choose and who you choose to purchase from.
