The pro-rata formula

Part-time NHS pay is brutally simple: full-time salary × (your contracted hours ÷ 37.5). Full-time in the NHS is 37.5 hours a week, so 30 hours is 0.8 whole-time-equivalent (WTE), 22.5 hours is 0.6 WTE, and 18.75 hours is 0.5 WTE. Everything salary-linked — basic pay, High Cost Area Supplement, recruitment premia — scales by the same fraction.

Take a Band 5 nurse at the 2026/27 entry step of £32,073. At 30 hours a week: £32,073 × (30 ÷ 37.5) = £25,658.40 a year. At 22.5 hours: £19,243.80. The formula never changes; only the inputs do. Your contracted hours are the ones in your contract and ESR record — if ESR shows the wrong hours, every payslip will be wrong, so verify it when you start.

One common misunderstanding: pro-rating applies to the salary, not to the band. A part-time Band 6 is still a Band 6, with the same pay steps, the same unsocial-hours percentages and the same terms — just fewer hours and proportionally less pay. Nothing about the band's structure is diluted by working part-time.

WTE fractions are also the language of job adverts and flexible-working requests, so it is worth learning the common ones: 37.5 hours is 1.0 WTE, 30 hours is 0.8, 22.5 hours is 0.6, 18.75 hours is 0.5, and 15 hours is 0.4. When a vacancy is advertised as "0.6 WTE Band 5", the salary range quoted is usually the full-time equivalent — multiply by 0.6 to see what you would actually be paid. If an advert quotes only the pro-rated figure, check which one you are looking at before comparing offers.

Part-time salaries by band and hours

Using 2026/27 England full-time rates, here is what common part-time patterns pay at the entry and top steps:

Worked take-home example: a Band 5 nurse at the entry step working 22.5 hours earns £19,243.80 gross. Pension (8.3% tier, set by whole-time-equivalent pay) is £1,597.24; income tax about £1,015.31; National Insurance about £533.90 — leaving roughly £16,097 a year, or £1,341 a month, before any enhancements. A Band 6 nurse at the top step working 30 hours (£38,493.60 gross) takes home roughly £2,351 a month on the same basis.

Hourly rates: the sanity check

Every band and step has an official hourly rate — useful for checking bank-shift pay and for comparing with agency rates. For 2026/27 in England:

Sanity check: hourly rate × contracted weekly hours × 52.2 ≈ your annual pro-rata salary. If a bank shift offer quotes an hourly rate wildly below your band's rate, something is off — check whether the rate includes or excludes enhancements and holiday pay before accepting.

Overtime and extra hours rules

This is where part-timers lose money through misunderstanding. If you are contracted for 22.5 hours and pick up an extra 7.5-hour shift, those hours are paid at plain time — your normal hourly rate — not at overtime rates. Contractual overtime rates (time-and-a-half, double time on public holidays, for Bands 1 to 7) only begin above 37.5 hours a week.

The logic is that overtime compensates for exceeding a full-time week; a part-timer working 30 hours total has not exceeded it. It feels unfair when you are covering a short-staffed ward, but it is the national rule — see our unsocial hours and overtime guide for the full rate table.

Two practical consequences. First, compare the plain-time rate for extra shifts against what the trust's bank would pay — bank rates sometimes include enhancements that make them more attractive than extra contracted hours. A 22.5-hour Band 5 nurse at the entry step earns £16.38 an hour plain time for extra shifts; if the trust's bank pays the same £16.38 plus a 30% night enhancement for the same hours, the bank shift wins on any unsocial hours. Second, extra hours still count for pension: they are pensionable pay, so they nudge up both your contributions and your career-average pension accrual.

There is one more boundary to watch: the 37.5-hour week. If your extra shifts take you above 37.5 hours in a single week, the hours beyond 37.5 attract contractual overtime rates — time-and-a-half for Bands 1 to 7. Rotas that regularly push part-timers past the full-time line should be raising a different conversation (about safe staffing and your contract), but the pay rule itself is clear.

Enhancements, HCAS and allowances

Unsocial-hours enhancements are percentages, so they scale naturally: work a night shift as a part-timer and you get the same 30% enhancement on those hours as a full-timer. What is pro-rated is anything paid as a flat annual sum. HCAS is the big one — a part-time inner-London Band 5 nurse gets the same 20% formula, but 20% of a part-time salary, subject to the pro-rated minimum and maximum.

Allowances such as on-call payments follow local arrangements but the principle is consistent: the WTE value is the headline, your payment is the WTE fraction. If an allowance looks like the full-time amount on your part-time payslip, query it — it may be correct (some allowances are flat), but it is worth the check.

Pension, leave and pay steps for part-timers

Pension: you pay contributions on your actual pensionable pay, but your tier is set by your whole-time-equivalent pay. A half-time Band 5 nurse at the entry step pays 8.3% — the tier for the £32,073 WTE salary — applied to their actual £16,036.50 salary. This is good news: you are not bumped into a higher tier by working extra shifts, because the tier looks at your WTE rate. See our pension contributions guide for the tier table.

Annual leave: pro-rated to your hours, and calculated in hours rather than days to keep it fair for varied shift patterns. Bank-holiday entitlement is also pro-rated — part-timers get a proportional share of the eight public holidays added to their leave, which evens out the rota lottery of whose rest days the holidays fall on.

Pay steps: progression runs on the same timetable — 2 years to the intermediate step, 5 years to the top — measured in calendar time in the band, not hours worked. The increase itself is pro-rated: 60% of the full-time step rise for a 0.6 WTE nurse. Our pay step guide has the cash values.

Sick pay and maternity pay: occupational entitlements are based on your actual pay, so they scale with your hours automatically. Statutory payments have their own earnings thresholds — very low-hours staff should check they clear the lower earnings limit for statutory sick pay and the earnings test for statutory maternity pay.

Frequently asked questions

How is NHS part-time pay calculated?

As: full-time annual salary × (your contracted hours ÷ 37.5). A Band 5 nurse at the entry step (£32,073) working 30 hours a week earns £32,073 × 30/37.5 = £25,658.40 a year. At 22.5 hours it is £19,243.80. Everything salary-linked — basic pay, HCAS, allowances — is scaled by the same fraction.

Do part-time NHS staff get overtime rates for extra shifts?

Not until they exceed 37.5 hours in the week. Extra hours above your contract but within a full-time week are paid at plain time — your normal hourly rate. Contractual overtime rates (time-and-a-half, double time on public holidays for Bands 1–7) only apply above 37.5 hours. Unsocial-hours enhancements are separate and apply to the unsocial hours you actually work.

Are unsocial-hours enhancements pro-rata for part-timers?

The percentages are not reduced — a part-timer working nights gets the same 30% enhancement on those hours as a full-timer. What scales down is anything expressed as an annual sum, like HCAS: you get the same percentage formula applied to your part-time salary, within pro-rated minimum and maximum caps.

Which pension tier applies if I work part-time?

Your tier is set by your whole-time-equivalent pensionable pay, then applied to your actual pay. A half-time Band 5 nurse at the entry step pays the 8.3% tier (the tier for the £32,073 WTE salary) on their actual part-time earnings. Extra shifts do not push you into a higher tier, because the tier is based on your WTE rate.

Do pay steps take longer if I work part-time?

No. Progression to the intermediate step (2 years) and top step (5 years) is measured in calendar time in the band, regardless of contracted hours. The pay rise itself is pro-rated — a 0.6 WTE nurse gets 60% of the full-time step increase — but the timetable is identical to full-time colleagues.

Is London weighting (HCAS) pro-rata for part-time staff?

Yes. HCAS uses the same percentage formula — 20% of basic pay for inner London, 15% for outer, 5% for fringe — applied to your part-time basic pay, with the minimum and maximum caps pro-rated to your hours. A part-time inner-London Band 5 nurse therefore receives 20% of their part-time salary as HCAS.
