Night Fire Watch for Construction Sites, planned around the premises.
Construction risks can remain after the workforce leaves, particularly where hot works, temporary electrics, incomplete fire precautions or stored materials are involved. Night cover requires current site instructions and a reliable handover from the day team.
For principal contractors, developers, site managers and fit-out teams arranging out-of-hours fire watch.
Every enquiry starts with the actual building or site. We review the reason for cover, the duties required, proposed staffing, operating hours and the instructions that personnel will need to follow. This avoids treating a temporary fire safety or security assignment as a generic guard booking.
When this service may be considered
Hot works finish close to site closure
Detection is incomplete or isolated
A vulnerable construction phase continues overnight
The site needs both fire watch and security
These examples are not a substitute for competent assessment. The responsible person and their appointed professionals remain responsible for determining the appropriate fire safety, evacuation or security arrangements for the premises.
Receive a current handover from the day team
Night personnel need the latest construction fire plan, active permits, alarm or detection status, changing routes, isolated areas and significant materials left on site. The site manager should identify work completed that day and any post-work monitoring still required. Verbal information should be supported by current written instructions.
Confirm who remains on site, which gates and buildings are accessible, the emergency contacts and how alarms are raised. The outgoing team should not assume night staff know about temporary barriers, open risers, plant or power changes that appeared during the shift.
Plan safe overnight patrols and communications
Routes must be safely lit and avoid prohibited areas. Personnel need suitable communication, lone-working controls, welfare and a check-in process. The patrol schedule should distinguish fire-watch zones from security perimeter duties and ensure one task does not leave the other uncovered.
If hot works have occurred, follow the permit's defined post-work period and areas, including adjacent spaces where specified. Any smoke, fire, unusual heat, alarm or unauthorised activity should trigger the relevant site escalation. Personnel should not investigate hazards beyond their training and authority.
Document the night and morning handback
Time-stamped patrols, incidents, access events and equipment issues should be recorded consistently. Urgent matters are communicated live, then documented. Supervisors should review missed checkpoints and repeated access problems rather than allowing unexplained gaps to pass between nights.
The morning handover should identify open actions, changes and any area requiring contractor attention. As the project evolves, the principal contractor should update routes and scope. Night fire watch supports the construction arrangements but does not replace permits, risk assessment or competent site fire-safety management.

Frequently asked questions
Practical answers about night fire watch for construction sites.
What should the day team hand over?
Current permits, works, hazards, alarm status, routes and open actions.
Can night fire watch also patrol the perimeter?
Only if duties do not conflict and suitable security licensing is in place where required.
Who updates the route?
Site management should issue changes as the construction phase evolves.
How quickly can cover be arranged?
Mobilisation depends on location, staffing levels, shift requirements and availability. For urgent requirements, call 0207 118 2477 so the brief can be reviewed immediately.
What information is needed for a quotation?
We normally need the site address, building use, reason for cover, required staffing, shift pattern, proposed start date and any relevant site or evacuation instructions.
