Construction sites across the UK can contain valuable plant, tools, fuel, copper, building materials and equipment. With sites often left unattended outside working hours, having the right level of security can help reduce the risk of theft, trespassing and damage. In 2026, construction site security typically costs around £15 to £30+ per hour for an SIA-licensed security guard, depending on the location, risk level, working hours and duties involved. Some providers publish rates around £16–£23 per hour, while higher-risk sites and areas with higher operating costs can reach £30 or more per hour. Other options, such as mobile patrols, CCTV monitoring, key holding and alarm response, are priced differently. This guide explains the typical construction site security cost in the UK, what affects the price and what you should consider when comparing security companies. How Much Does Construction Site Security Cost in the UK? Construction security does not have one fixed UK price. Security companies normally price a site according to the type of protection required, the number of hours, site conditions and level of risk. For budgeting purposes, current UK pricing gives a useful starting point. How Much Does a Construction Security Guard Cost? Manned guarding is one of the most common security options for UK construction sites. A security officer can control access, monitor deliveries, check visitors, carry out patrols and record incidents. Current UK pricing sources put construction guarding broadly between £15 and £30+ per hour, with many published construction-specific rates sitting around £16–£28 per hour. Key points Guards deployed on construction sites should have the appropriate SIA licence for the work they perform. The hourly rate normally covers more than the guard’s basic wage. Costs can include recruitment, vetting, training, uniforms, insurance, management and holiday cover. Higher-risk sites can require higher rates. Longer shifts and unsocial hours can affect the price. London and the South East can have higher rates than many areas of the North and Midlands. How Much Does Night Construction Site Security Cost? Night security is particularly relevant for construction sites because the site may be largely empty after contractors and workers leave. A security guard can remain on site during the night, monitor access points and carry out regular checks of the perimeter and vulnerable areas. UK security pricing guides commonly show night guarding at a higher rate than standard daytime guarding, with figures around £16–£35 per hour being common and higher rates possible for specialist or high-risk work. Key points Night guarding can protect sites outside normal working hours. Guards can check gates, fencing, compounds and storage areas. Security officers can monitor unauthorised access. Night rates may be higher than standard daytime rates. The number of hours required directly affects the monthly cost. Weekend and bank holiday shifts can have additional pricing. How Much Does 24/7 Construction Site Security Cost? 24/7 construction security means maintaining security coverage throughout the day and night. It does not mean one guard works continuously for 24 hours. A proper rota is required to provide continuous cover. Current UK guides show a wide range for 24/7 security because the cost depends on the number of officers, shift pattern, location and whether the site requires one or multiple security posts. Some UK providers quote approximately £15–£35+ per hour, while other calculations for continuously staffed posts are considerably higher. Key points 24/7 cover requires multiple shifts or officers. Large sites may need more than one security post. London and the South East can have higher operating costs. Night, weekend and bank holiday hours can affect pricing. A site risk assessment is normally needed before deciding on continuous cover. CCTV and mobile patrols may be used alongside guarding. How Much Do Mobile Security Patrols Cost? Mobile patrols are an option for construction sites that do not need a security officer permanently stationed on the premises. A mobile security officer visits the site at agreed times, checks the property and reports any issues found during the patrol. Current UK pricing varies considerably. Securitas gives a general mobile patrol range of around £25–£50per hour, while construction-focused providers may charge per visit or provide monthly patrol packages. Key points Mobile patrols can be used during nights and weekends. They can check gates, fencing and vulnerable areas. Patrols can support CCTV and alarm systems. Visits can be scheduled according to the site’s risk. The price depends on travel distance, patrol frequency and time spent on site. A lower-risk site may not require a permanent guard. How Much Does Construction Site CCTV Cost? Temporary CCTV is increasingly used on UK construction sites, particularly where a site covers a large area or has sections that are difficult for a single guard to monitor. The cost depends on the type of cameras, number of units, monitoring service, connectivity, installation and response arrangements. Key points Temporary CCTV towers can be hired for construction sites. Remote monitoring can allow operators to respond to detected activity. CCTV can cover entrances, storage compounds and perimeter areas. Lighting and camera positioning affect how useful the system is. Monitoring and response may be separate from equipment hire. Larger sites usually require more cameras or towers. What Affects Construction Site Security Costs? Several factors can change the final price of construction security. 1. Site Size The size of a construction site can have a direct impact on security costs. A small development with one entrance is generally easier to monitor than a large project covering several acres. Larger sites may require more security guards, additional mobile patrols, extra CCTV cameras, several access points, security vehicles and more frequent site inspections. As the area that needs to be monitored increases, more staff, equipment and patrol coverage may be needed, which can increase the overall security requirement and cost. 2. Location Security prices vary across the UK. London and some areas of the South East can have higher operating costs than many other regions. Travel time and the availability of suitable officers can also affect the price. A security provider should therefore consider the
