Plan security around each project phase
Groundworks, deliveries and fit-out create different access requirements. Identify the gates in use, pedestrian routes, material stores and plant compounds. Review the brief when fencing moves, a new contractor arrives or the site closes for a holiday.

Construction site guarding and security services
Gate control and static guarding
Security guards can check arrivals against authorised lists, record deliveries and report exceptions. Agree who approves unexpected visitors and who can release equipment. A gate post and a perimeter patrol may need separate cover if both must operate at the same time.
Overnight K9 patrols
A dog and handler team can support perimeter deterrence where the site assessment makes this suitable. Define patrol boundaries, occupied areas, welfare arrangements and how other workers will be kept separate.
Mobile patrols and CCTV
Scheduled patrol visits provide checks at agreed intervals; they do not provide continuous attendance. CCTV towers or cameras need suitable positioning, power, connectivity and an agreed process for acting on alerts.
For battery storage and infrastructure projects, explore BESS and energy site security. For temporary camera coverage, see CCTV towers and site cameras.
Protecting plant, machinery, tools and materials
Identify the assets that remain on site after work ends: plant, fuel, tools, cabling and material stores. Agree which compounds are checked, who can authorise equipment leaving and how damaged fencing, unsecured doors or suspicious activity are reported. Keep an up-to-date record of authorised movements so officers can refer exceptions to your site manager.
Alarm monitoring and incident escalation
For suitable cabins or enclosed premises, Ajax alarm installation and monitoring can complement guarding and CCTV. Our in-house team monitors our alarm systems 24 hours a day. Following a confirmed activation, we dispatch an emergency response team and contact the police when appropriate. Access, verification and escalation arrangements are agreed for each assignment; attendance times are not guaranteed.
Guard supervision, handovers and reporting
Our approach prioritises direct supervision, reliable site coverage and practical communication with your nominated manager. Agree reporting recipients, escalation contacts and the checks required at each post. Handover instructions should record unresolved incidents, access changes and expected deliveries so the next shift has the information it needs. Read our guard shift handover guide.
Short-term cover and ongoing construction contracts
Discuss a weekend closure, temporary compound, project delay or a longer construction programme. Specify the dates and duties, then review the arrangement as the project changes. Groundworks may need perimeter checks; the main build may need delivery control and plant protection; fit-out may add contractor movements and tools stored inside.
What affects construction security costs?
The number of staffed gates, shift length, overnight duties and project duration shape the quote. Separate continuous guard posts from patrol visits and CCTV requirements so you can compare the same scope. Include relief cover, reporting and any mobilisation requirements in the proposal.
What to include in your site brief
- Project postcode, start date, expected duration and site plan.
- Number of gates, delivery hours and required security shifts.
- Plant, fuel and materials needing particular attention.
- Site induction, welfare access and emergency contacts.
- Reporting requirements and any insurer conditions.
Security officers work to the agreed assignment. Traffic management, lifting operations and specialist safety duties need their own competent personnel and arrangements.

Frequently Asked Questions
Can you provide 24-hour construction site security in Watford?
Request the hours and posts you need covered, including nights, weekends and bank holidays. We confirm staffing, relief cover, duties and the start date before the assignment begins.
Can one guard handle the gate and patrol the perimeter?
A guard away on patrol cannot maintain an uninterrupted gate post. If both duties must operate together, they need separately planned cover.
How quickly can construction security start?
Send your postcode, proposed start date and shift requirements. We assess the assignment and confirm availability; no deployment time is guaranteed before the booking is agreed.
Can guarding and CCTV be combined?
Yes, they can form part of the same brief. Define who monitors alerts and who is authorised to attend or escalate.
What happens if the site layout changes?
Tell us when gates, fences, storage or working hours change so the patrol and access instructions can be reviewed.
