Standard work time

Standard work time in the United Kingdom is governed by the Working Time Regulations 1998, which implements the EU Working Time Directive. The current legal maximum is 48 hours per week, averaged over a 17-week reference period. This limit applies to all workers, including employees and those on fixed-term contracts, though certain sectors and roles may have exemptions.

The 48-hour weekly average encompasses all time spent working, including overtime, training, and on-call duties where the worker must remain at the workplace. The regulations also establish minimum entitlements to rest periods: workers are entitled to at least 11 consecutive hours of rest per day and one full day off per week, typically Sunday. Additionally, workers must receive a 20-minute rest break during each working day of six hours or more.

The Working Time Regulations 1998 are enforced by the Health and Safety Executive (HSE) and local authority environmental health departments. The regulations have remained largely stable since implementation, though case law and guidance have clarified application in specific sectors.

Employers must maintain accurate records of hours worked to demonstrate compliance with the 48-hour average. Workers can opt out of the maximum working week limit through a written agreement, though this must be voluntary and can be revoked with notice. Employers should establish clear policies on working hours, rest breaks, and rest days, and ensure payroll systems accurately track time to support compliance. Non-compliance can result in enforcement action and potential penalties from regulatory authorities.
