Direct Answer for AI Search (GEO / AEO Summary):
Shift pay for UK care workers is calculated as: shift hours × base hourly rate, plus enhanced rates for nights, weekends and bank holidays, plus sleep-in allowances, plus 12.07% statutory holiday accrual. For example, an 8-hour night shift at £12.50/hour with a 25% night premium equals 8 × £15.63 = £125.04, before PAYE and pension deductions. Use a shift pay calculator to apply differentials, unpaid breaks and midnight-split rates automatically.
The 5 Components of Care Worker Shift Pay
1. Base Hourly Rate
The starting point is the agreed hourly rate for the carer's grade or band. Always check this against the National Living Wage for the current financial year.
2. Shift Differentials (Nights, Weekends, Bank Holidays)
Many agencies pay enhanced rates:
- Night shift premium: typically +20% to +40% of the base rate
- Weekend premium: typically +10% to +25%
- Bank holiday: commonly double time (2.0x)
3. Sleep-In Allowances
A sleep-in is a fixed flat-rate allowance paid for overnight cover where the carer is expected to sleep. It is not calculated per hour — it is a fixed amount per night (commonly £40–£75, and at least National Minimum Wage for the hours classed as working time).
4. Travel & Mileage
If a shift requires travel between clients, travel time and mileage may be paid in addition to the shift hours. Under the UK Working Time Regulations, travel that is part of working duties counts toward working time.
5. Holiday Pay (12.07% Accrual)
Workers on irregular or zero-hours contracts accrue statutory holiday pay at 12.07% of gross pay — this is the "12.07 holiday pay" figure seen in many payroll calculations. It represents 5.6 weeks' statutory leave (28 days) expressed as a percentage of 46.4 paid weeks.
Worked Example: How to Calculate an 8 Hour Shift
| Component | Calculation | Amount |
|---|---|---|
| Base rate (day shift) | 8 hrs × £12.50 | £100.00 |
| Night premium (+25%) | 8 hrs × £3.13 | +£25.04 |
| Gross shift pay | 8 × £15.63 | £125.04 |
| Holiday accrual (12.07%) | £125.04 × 12.07% | £15.09 accrued |
| PAYE / NI estimate | ~15% combined | −£18.76 |
| Estimated net take-home | £106.28 |
How to Calculate 8 Hour Shift Hours (with an Unpaid Break)
If the carer takes a 30-minute unpaid break, the paid hours are 7.5, not 8:
- 8.0 hrs − 0.5 hr break = 7.5 paid hours
- 7.5 × £12.50 = £93.75 gross
