Working Time Regulations for Security Guards: An Employer’s Guide

For ACS compliance, this is important. The Working Time Regulations 1998 set legal limits on working hours across the UK. For security companies running 24/7 operations with rotating shifts, understanding and complying with these regulations is crucial to avoiding employment tribunals and HSE enforcement action.

Maximum Working Hours

Workers cannot be required to work more than an average of 48 hours per week, calculated over a 17-week reference period. This means a guard could work 60 hours one week if compensated by lighter weeks, provided the rolling average stays at or below 48 hours.

Guards can voluntarily opt out of the 48-hour limit by signing a written agreement. However, the opt-out must be genuinely voluntary — you cannot make it a condition of employment or penalise workers who refuse to sign.

Rest Break Entitlements

Guards working more than six hours are entitled to a minimum 20-minute uninterrupted rest break. They must also receive 11 consecutive hours of rest between shifts and at least one full day off per week (or two days off per fortnight).

Night workers face additional restrictions: they should not work more than an average of eight hours in any 24-hour period, and employers must offer free health assessments to night shift staff.

Common Compliance Issues

Security companies frequently run into trouble with back-to-back shifts that don’t allow 11 hours’ rest between them, guards working excessive overtime without opt-out agreements, inadequate break provision during 12-hour shifts, and failing to monitor total hours across multiple site assignments.

Digital time tracking and roster management systems make compliance significantly easier by automatically flagging rest period violations and excessive hours before they become a problem.

Practical Steps for Compliance

Review your rostering practices against the regulations, ensure opt-out agreements are properly documented, implement a system to track actual hours worked (not just scheduled hours), and train supervisors to recognise and report rest period concerns. Regular audits of timesheets against roster data will highlight any patterns of non-compliance before they attract enforcement attention.
