Construction Site Security
Construction sites are among the most targeted locations for theft in the UK. Plant machinery, copper cabling, building materials and tools disappear overnight, and the cost goes beyond what was taken. A single incident can stall your programme for days, complicate your insurance position and damage your relationship with a client who is watching the clock. USSG provides construction site security across the United Kingdom with directly employed, SIA licensed officers who know how build sites work and what it takes to keep them properly protected. Every officer is vetted to BS 7858 standard before their first shift on any site.
Why Construction Sites Need Specialist Security
A guard without construction experience creates gaps that organised criminal groups are very good at finding. Build environments have risks and procedures that are specific to the sector. Managing subcontractor access, handling visitor sign-in during active hours, knowing what a CDM site manager needs from a security team, these are things that come from working on sites, not from reading about them. An officer who does not understand these things will cause problems rather than prevent them.
Our construction site security officers have genuine experience on active build sites across the UK. They understand SIA licensed security guarding in build environments specifically, not just in theory. They know how to manage access points during working hours and how to secure a site properly for overnight and weekend closure. They maintain site records that hold up to scrutiny, and they know how to identify and report hazards as well as security incidents. That depth of knowledge is what separates a proper construction site security operation from someone with a badge standing at a gate. Their experience on active sites allows them to work alongside wider Security Services UK operations, ensuring site protection remains consistent throughout every stage of the project.
Construction Site Security Services from USSG
Every build site carries different risks at different stages of the project. We assess yours and build a plan around what we actually find, not around a standard package.
Static Manned Guarding
A dedicated SIA licensed officer stationed at your construction site for the agreed shift. Our static guards control access at the site entrance, carry out regular perimeter patrols and respond to incidents in real time. Every officer is directly employed by USSG, vetted to BS 7858 standard and briefed on your specific site before their first shift. For sites with significant plant or materials on site, a permanent presence is the most effective deterrent available.
Mobile Security Patrols
Our patrol vehicles visit your construction site at set times and randomised intervals through the night and at weekends. On each visit the officer checks gates, perimeter fencing, plant compounds, material stores and welfare facilities, then provides a written patrol report. Mobile patrols work well for lower-risk sites and as a complement to static guarding on larger or multi-phase developments where full-time guarding costs need to be managed.
Alarm Response
If your construction site has an existing intruder alarm, our key holding and alarm response service means one of our officers attends whenever it activates. We check the full site, liaise with police where required and secure the premises properly before leaving. A written attendance report follows every call-out. Our response team is available every hour of every day, including weekends and bank holidays, with no exceptions.
What Construction Site Theft Actually Costs UK Contractors
Plant theft costs the UK construction industry over £800 million every year according to the Construction Equipment Association. That figure does not include copper theft, fuel theft, material theft or vandalism, all of which continue to rise. In 2026, organised criminal groups are using drone reconnaissance to map construction sites before targeting them. They know where the plant is parked, which gates are left unsecured at weekends and which sites have a proper security presence and which ones rely on a padlock and hope.
The direct financial loss from a theft is rarely the biggest problem. A concrete pump stolen on a Friday night can shut down a pour scheduled for Monday morning. Materials stripped from a half-built structure can set a programme back by weeks. When you add management time spent dealing with insurance claims, the cost of temporary replacement equipment and the reputational pressure on your client relationship, the case for proper construction site security from day one is straightforward.
What to Expect When You Work With USSG
Before we place a single officer on your site, we carry out a proper assessment. We look at the perimeter, the access points, the location of high-value plant and materials, the welfare facilities and any specific risks your principal contractor or site manager has flagged. We talk to the people who know the site day to day, not just the person who signed the contract.
From that assessment we build a security specification that fits your site and your budget. We provide a fixed written quotation with no hidden extras before anything is agreed. Most contracts are up and running within 24 to 48 hours of written confirmation. Once you are live, you have one account contact who knows your site and your team. If there is a problem, you call one number and reach someone who can act on it.

Frequently Asked Questions About Construction Site Security
Common questions from businesses looking for construction site security across the UK.
Construction site security involves protecting build sites from theft, vandalism and unauthorised access. It typically combines SIA licensed static guards, mobile patrol visits, CCTV towers, alarm response and access control. The right mix depends on the size of the site, the value of plant and materials on site and how long the project runs. USSG carries out a proper site assessment before recommending anything.
Static guarding starts from approximately £14 to £22 per hour for an SIA licensed officer. Mobile patrol packages are charged per visit or on a fixed monthly basis. CCTV tower hire is typically charged on a weekly basis. USSG provides fixed written quotations with no hidden extras, tailored to your specific site and what it actually requires.
Yes. Overnight construction site security is one of our most commonly requested services. Our SIA licensed officers are trained for the specific risks that arise outside working hours, including plant theft, copper cable theft and access by organised criminal groups who increasingly use drone reconnaissance to identify targets before moving on them.
USSG can typically have SIA licensed officers on your site within 24 to 48 hours of written confirmation. For genuine emergencies, same-day deployment is sometimes possible. Call 0330 341 2124 and we will confirm availability and a start time straight away.
