Securing Your Site: Heras Fencing, Hoarding & Perimeter Options

An unsecured construction site is a liability in every sense — legally, financially and morally. You have a duty to keep the public out and the site safe, theft and trespass cost the construction industry heavily every year, and an accident involving a member of the public (especially a child) on an unsecured site is a nightmare no contractor wants. Getting your perimeter right is one of the first jobs on any site. Here’s a guide to the main options and when to use each.

Why Site Security Is a Legal Duty, Not a Choice

Under CDM 2015 and general health and safety law, contractors must take reasonable steps to prevent unauthorised access to a construction site. That means securing the perimeter so the public — particularly children, who are drawn to sites — can’t wander in. It’s not just best practice; failing to secure a site can bring HSE enforcement and leave you liable if someone is hurt.

Beyond compliance, there’s the hard commercial case: construction sites are targets for tool, plant and material theft, and metal theft. A secure perimeter is your first and cheapest line of defence.

The Main Perimeter Options

Temporary mesh fencing (Heras-type) The workhorse of site security. Freestanding steel mesh panels slot into rubber or concrete feet and clip together, forming a quick, movable perimeter. Ideal for:

• Fast setup and takedown
• Sites where the boundary changes as work progresses
• General perimeter control on most construction and groundworks sites

Look for anti-climb specification, and secure panels together with proper clips so they can’t simply be lifted apart — poorly clipped mesh fencing is easily defeated.

Hoarding Solid timber or steel panel fencing, typically taller and fully enclosed. Chosen when you need:

• A visual screen (public-facing sites, high streets, retail frontages)
• Higher security and a more permanent-feeling boundary
• A surface for branding or safety signage
• Dust and debris containment

Hoarding is the go-to for town-centre and public-facing sites where mesh fencing would look unfinished and offer less screening — it pairs naturally with the kind of retail and shopfitting projects where the site meets the public.

Pedestrian and vehicle barriers For controlling movement rather than sealing a boundary — separating pedestrians from vehicle routes, managing access points, and directing foot traffic safely around or past a site. Often used alongside fencing rather than instead of it.

Choosing the Right Option

Ask:

• Public exposure? High-street or public-facing → hoarding. Remote or fenced-off → mesh fencing usually suffices.
• How long is the site running? Short jobs → mesh fencing’s speed wins. Long, high-profile projects → hoarding.
• Does the boundary move? Evolving groundworks → movable mesh panels. Fixed footprint → hoarding.
• Theft risk? High-value plant and materials → higher-security options and consider access control at entry points.
• Screening needed? Dust, mess or public sightlines → solid hoarding over open mesh.

Many sites use a combination: hoarding on the public-facing frontage, mesh fencing around the rest, and barriers to manage the access point.

Don’t Overlook Secure Storage

Fencing keeps people out of the site, but tools and materials left in the open inside the perimeter are still vulnerable. Secure storage containers on site give you a lockable, steel home for valuable kit overnight — a sensible pairing with your perimeter fencing, and available as part of the same site equipment offering.

Set the Whole Site Up in One Go

Perimeter security is one element of getting a site operational — it sits alongside welfare facilities, storage, and waste collection or skips. Sourcing fencing, welfare and waste from one nationwide provider means a coordinated setup and a single point of contact, rather than chasing three suppliers to get a site open on time.

Select A Skip supplies perimeter fencing and site equipment across the UK. Get in touch with your site details and we’ll help you secure it properly from day one — we reply the same working day.
