Working Time Regulations checker

Check whether a rota pattern complies with the UK's 48-hour weekly limit, night-worker rules, 11-hour daily rest gap and rest-break entitlement — in seconds.

Average hours per week: 40h

Night worker (works at least 3 hours between 11pm–6am most nights)

40h/wk — 48-hour limit

Within the 48-hour average working-week limit (averaged over 17 weeks). The full schedule is legal.

Based on the Working Time Regulations 1998 as amended. Averaged limits use a 17-week reference period (or 26 weeks for some sectors). Certain sectors and roles have different rules. Young workers (under 18) have stricter limits. Not legal advice — check GOV.UK or a qualified adviser for your situation. WagePilot tracks shifts and flags potential rota conflicts automatically.

Working Time Regulations: the essentials

The Working Time Regulations 1998 (as amended) set a floor of protections for almost every UK worker. The rules most relevant to small shift businesses are:

48-hour average week — workers must not average more than 48 hours a week, measured over a 17-week rolling reference period. Workers can opt out in writing, but cannot be forced to.
11-hour daily rest — there must be at least 11 consecutive hours between the end of one shift and the start of the next. A midnight finish means no earlier than 11am the following day.
20-minute rest break — any shift longer than six hours entitles the worker to an uninterrupted 20-minute break during (not at the start or end of) the shift.
24 hours' weekly rest — workers are entitled to at least one day off per week (or 48 hours in a fortnight). Some sectors can compress this.
Night workers — if someone regularly works at least three hours between 11pm and 6am, their average daily hours must not exceed eight across a 17-week period. Free health assessments must be offered.

Breaches can be enforced by the Health and Safety Executive, and workers can bring tribunal claims. WagePilot flags potential rota conflicts — like back-to-back shifts with under 11 hours of rest — before you publish, so issues are caught at the planning stage rather than after the fact.

Working time questions

What is the 48-hour working week limit?

Under the Working Time Regulations 1998, workers must not average more than 48 hours per week over a 17-week reference period. Workers can voluntarily opt out in writing, but you cannot force or pressure them to do so.

Can workers opt out of the 48-hour limit?

Yes. An individual opt-out agreement must be in writing and signed freely by the worker. It can be withdrawn with at least 7 days' notice (or up to 3 months if agreed). Pressuring staff to sign an opt-out is unlawful.

What rest break are workers entitled to?

Workers who work more than 6 hours in a day are entitled to one uninterrupted rest break of at least 20 minutes. The break should not be at the start or end of the working period. Young workers (under 18) working more than 4.5 hours get a 30-minute break.

What is the 11-hour daily rest rule?

Workers are entitled to at least 11 consecutive hours' rest in every 24-hour period. So if a shift ends at midnight, the next shift should not start before 11am. Some sectors (e.g. security, hospitality) have compensatory rest provisions.

What are the extra rules for night workers?

Night workers — those who regularly work at least 3 hours during the night period (11pm to 6am) — must not average more than 8 hours in each 24-hour period over a 17-week reference period. Night workers also have a right to free health assessments.

Do the Working Time Regulations apply to all workers?

Most UK workers are covered, including agency and part-time workers. Some sectors (e.g. transport, offshore, armed forces) have different or excluded rules. Young workers (under 18) have stricter limits. Genuinely self-employed workers are not covered.
