UK Employment Law on Rest Breaks: A Detailed Guide

The Working Time Regulations 1998

The primary legislation governing rest breaks in the UK is the Working Time Regulations 1998, which implemented the EU Working Time Directive into UK law. These regulations remained in force after Brexit and continue to protect workers' rights to rest breaks, daily rest, and weekly rest periods. Under Regulation 12, adult workers (aged 18 and over) who work more than six hours in a day are entitled to a rest break of at least 20 minutes, which should be uninterrupted and taken away from their workstation.

Young Workers Have Additional Protections

Workers under 18 have enhanced break entitlements under UK law. Young workers (aged 16-17) are entitled to a 30-minute rest break if they work more than 4.5 hours, rather than the 6-hour threshold for adults. They are also entitled to 12 hours of uninterrupted daily rest (compared to 11 hours for adults) and two consecutive days off per week. Employers must be aware of these stricter requirements when employing young workers in part-time or apprenticeship roles.

Sectors with Special Break Rules

Certain industries have additional or modified break requirements:

• Road transport (HGV and PSV drivers): Governed by EU Regulation 561/2006 (retained in UK law). Drivers must take a 45-minute break after 4.5 hours of driving. This can be split into a 15-minute break followed by a 30-minute break.
• Healthcare (NHS): NHS Employers recommends that staff working 12-hour shifts receive at least one 30-minute paid break and two 15-minute breaks. Many NHS trusts have specific policies that exceed the legal minimum.
• Screen-based work (DSE): While not strictly "lunch breaks," the Health and Safety (Display Screen Equipment) Regulations 1992 require employers to plan work so that there are regular breaks or changes of activity for employees who use screens habitually. HSE guidance suggests short, frequent breaks are more beneficial than occasional longer ones.
• Night workers: If a night worker's work involves special hazards or heavy physical or mental strain, they should not work more than 8 hours in any 24-hour period. Adequate breaks during night shifts are essential for health and safety compliance.

What to Do If Your Employer Denies Breaks

If your employer consistently fails to provide your legal rest breaks, you have several options. First, raise the issue informally with your line manager or HR department. If this does not resolve the matter, consider filing a formal grievance following your employer's internal procedure. You can also contact ACAS (Advisory, Conciliation and Arbitration Service) on 0300 123 1100 for free, impartial advice. As a last resort, you can bring a claim to an Employment Tribunal, though you must normally do this within three months of the breach. Workers cannot be dismissed or subjected to detriment for asserting their right to rest breaks.
