NHS Pension for Part-Time Staff Explained

A huge proportion of the NHS workforce works part-time at some point in their career, whether that's a fixed part-time contract, a job-share, or hours that flex up and down around caring responsibilities, study, or a phased return from illness. One of the most common — and most reasonable — questions that comes up is whether part-time working means a worse pension deal. This guide explains, in general terms, the specific mechanic that answers that question: what pensionable pay actually means for part-time staff, and how it feeds into the CARE accrual mechanics described in our NHS Pension Scheme (2015) explained guide.

Actual pensionable pay, not full-time-equivalent salary

This is the single most important clarification for part-time NHS staff to understand about their pension: the NHS Pension Scheme's CARE accrual is calculated on what you were actually paid in pensionable pay for a given scheme year — not on the salary you'd have earned had you worked full-time in the same role. Full-time-equivalent (FTE) salary is a useful reference figure used elsewhere (for example, in job advertisements and pay scales), but it is not the figure your contribution tier or your annual pension accrual is calculated from. The contribution tiers for every NHS scheme are on our NHS pension contribution rates 2026/27 page.

This matters because it's easy to see an FTE salary figure quoted for your band and role and assume that's what your pension is being built on — it isn't, if you work part-time hours. It's not a penalty or a different treatment for part-time staff; it's simply the same rule — 1/54th of actual pensionable pay — applied consistently to whatever your actual pay happens to be.

A worked example, using the same accrual rate behind our calculators

Say a role has a full-time-equivalent salary of £34,000, and you work 60% of full-time hours in that role. Your actual pensionable pay for the year is roughly:

£34,000 × 60% ≈ £20,400 of actual pensionable pay.

Applying the 2015 Scheme's 1/54th accrual rate to that actual pay gives:

£20,400 ÷ 54 ≈ £378 of annual pension, banked for that scheme year.

Compare that with what accrual would have been if the scheme used the full-time-equivalent figure instead (which, to be clear, it doesn't): £34,000 ÷ 54 ≈ £630. The gap between 378 and 630 in this example is simply the 60% hours factor showing up directly in that year's accrual — not a different rate, not a penalty, just the same 1/54th rule applied to a smaller actual pay figure. Every subsequent year, this slice is revalued along with the rest of your CARE pot in exactly the same way as a full-time colleague's, as described in our NHS Pension Scheme (2015) explained guide.

A part-time career still builds a pension — just at a proportionally smaller rate per year

It's worth being clear about what this mechanic does and doesn't mean. It does not mean part-time staff are excluded from, or disadvantaged within, the scheme's rules — the accrual rate, revaluation, and every other mechanic described in our 2015 Scheme guide apply identically regardless of hours worked. What it does mean is that, all else being equal, a given number of years worked part-time will generally produce a smaller total pension than the same number of years worked full-time, simply because each year's actual pensionable pay — and therefore each year's accrual — is smaller.

Over a full career, many NHS staff move between full-time and part-time hours more than once — for example, reducing hours during a period of caring responsibilities and increasing them again later, or the reverse. Because the 2015 Scheme's CARE design adds up individual years' accrual rather than looking back at a single final salary figure, there's no need to reconcile a "part-time period" against a "full-time period" in some special way — every year simply contributes whatever 1/54th of that year's actual pay works out to be, and the running total is revalued the same way regardless of the pattern of hours behind it.

How changing your hours affects accrual going forward

Because CARE accrual is calculated year by year on actual pay, a change in your hours — up or down — generally affects your pension accrual from the point the change takes effect, not retrospectively:

• • Increasing your hours generally means higher actual pensionable pay from that point onward, and therefore a bigger slice of annual pension accrued in the years you work the increased hours
• • Reducing your hours generally means lower actual pensionable pay from that point onward, and therefore a smaller slice of annual pension accrued in the years you work the reduced hours
• • Pension already accrued in previous years doesn't change — a change in hours affects future accrual, not the pension you've already banked based on your pay in earlier years
• • Your contribution tier also follows actual pay — NHSBSA sets the tier on actual annual pensionable pay, so working fewer hours can move you into a lower tier as well as reducing accrual

If you're weighing a change in hours partly with pension in mind — alongside all the other factors that legitimately go into that decision — our NHS Pension Calculator lets you model different pensionable pay assumptions over time, though it's a planning tool built on illustrative assumptions, not a substitute for your own Total Reward Statement.
