Only the hours inside the night window earn the premium. In law, night time is 11pm to 6am unless the contract sets other hours.

2h × £12.71 + 8h × £19.07 = £177.98, with ×1.5 on the night hours.

Minimum wage: the £12.71 base is at or above £12.71 for workers aged 21 and over (from 1 April 2026). Premium pay doesn't count towards minimum wage, so the base has to clear it on its own.

The same shift under each rule

UK law sets no premium for nights, weekends or bank holidays: which hours earn one, and at what rate, comes from the contract. Rates are rounded to the penny, as on a payslip.

From a calculator to every payslip

Stop calculating shift pay by hand — TimeTally does it automatically

This calculator gives you the numbers. TimeTally applies the correct premium rate to the hours your rules cover automatically — so your payroll is always accurate from £3/employee/month.

  1. All shift types tracked automatically

    Set your premium hours once: the night window as overtime by time of day, an overtime rule for any day of the week, and a bank holiday rate. TimeTally applies the right multiplier to every timesheet entry automatically — no manual adjustments, no errors.

TimeTally does this for you

Select any feature for the detail.

  • Overtime that works itself out.

    Two triggers: threshold overtime kicks in once an employee exceeds a set number of hours per day or week. Time-of-day overtime pays a premium for hours worked in a specific window (e.g. after 6pm or before 6am), regardless of total hours. Two pay methods: a rate multiplier (e.g. 1.5×) or a fixed hourly rate for overtime hours. Stack multiple rules, build tiers, and configure each employee independently.

  • Know exactly where the hours went.

    Entirely optional — only enable it if you need it. When on, employees split their hours across projects when submitting (e.g. 3h on Client A, 4h on internal work). You can set project pay for the worker: an hourly rate on top of or instead of their usual rate, or a flat fee per entry (useful for callouts or site visits). Managers get a clear breakdown of where time is actually going.

  • Offer time off instead of overtime pay.

    An optional alternative to paying overtime — enable it only if you want to offer time off in lieu instead of (or alongside) extra pay. Set a TOIL conversion rate (e.g. 1h overtime = 1.5h leave) and overtime hours automatically accrue as a TOIL balance — no manual tracking. TOIL is kept separate from annual leave so it never eats into holiday entitlement. Employees book it the same way they book any other leave.

  • Approve a whole week from your phone.

    Managers approve or reject timesheets from any device — phone, tablet, or desktop. Rejections include a written reason so employees know exactly what needs fixing and can resubmit. Managers can see who has not submitted for the period, and are emailed as each timesheet comes in. Pay totals are calculated automatically from approved hours — no manual maths at payroll time.

  • Clock in, or fill in a form.

    Two submission modes — employees use whichever fits their workflow. Clock-in mode starts a live timer the moment they begin their shift. The timer runs in the background even if the app is closed, so no hours are lost. Form mode lets them enter start time, end time, and breaks at the end of the day or week. Both work on mobile and desktop.

  • Every hour costed at the right rate.

    Set each employee's own hourly rate and pay totals are calculated automatically from their approved hours. Scope managers to their department so they only ever see their own team's data. Want to keep salaries private? Hide pay rates and totals from managers entirely — they see hours, but never figures. Full control over who sees what.

  • Straight into Xero or QuickBooks.

    Send approved timesheets to payroll in a few taps. Export to CSV, Xero, or QuickBooks — filter by date range, employee, or department, and choose exactly which columns to include. You can combine timesheet and leave data in a single export so your payroll software gets everything it needs in one file.

UK Shift Premium Pay — Common Questions

Everything you need to know about enhanced pay for night shifts, weekends and bank holidays. For related topics, try our overtime pay calculator or minimum wage calculator.

Is there a legal right to enhanced pay for night or weekend shifts?

No. UK law does not require any premium pay for unsocial hours such as nights, weekends or bank holidays. The only legal floor is the National Minimum Wage, which applies at any hour of the day or night. Any enhanced rate — whether time and a half, double time, or a flat addition — is contractual. Always check your employment contracts or company pay policy to understand what rate applies.

What is the legal minimum for night workers?

Night workers (those who regularly work at least three hours between 11pm and 6am) must not exceed an average of eight hours per 24-hour period, calculated over a 17-week reference period. Employers must also offer night workers free health assessments before they start and at regular intervals. However, the pay rate itself has no legal minimum above the National Minimum Wage — there is no statutory night shift premium.

Does time and a half count towards NMW compliance?

No — only the base rate counts. Under the National Minimum Wage Regulations 2015, the part of a premium rate above the lowest rate a worker could be paid for the same work (the extra half in time and a half for nights or weekends, say) does not count towards minimum wage pay. For example, a worker earning £7/hr base with a 1.5× premium earns £10.50/hr for those hours, but it is the £7 that is checked, and it is below the £12.71 minimum for over-21s from April 2026, so the worker is underpaid however many premium hours they work. Only where a worker has no lower rate for that work (they only ever work nights, at one rate) does the whole rate count. Use this calculator to check whether your base rate clears the NMW floor.

Can I pay a flat-rate addition rather than a multiplier?

Yes. Many hospitality and care businesses pay £1–£3 per hour extra for night or weekend work rather than using a multiplier. This is perfectly legal as long as the base rate on its own stays at or above the National Minimum Wage for the worker's age group: like a multiplier, a flat addition for unsocial hours does not count towards minimum wage pay. Some employers find flat additions simpler to communicate and easier to budget for than percentage multipliers.

How do I track which hours qualify for premium pay?

You need a timesheet system that records shift start and end times, so you can see which hours fall in the premium period. TimeTally does this from clock-ins or timesheets, and can pay those hours at a higher rate for you: set your night hours (say 22:00–06:00) as overtime by time of day, give a day of the week its own overtime rule, and switch on a bank holiday rate. Hours worked in them are priced at the multiplier you choose, or each person's own overtime rate, on every timesheet entry. See our guide on night shift time tracking for more detail.
