NHS Pay
How to Read Your NHS Payslip
Independent guidance — not affiliated with NHS England or DHSC
Most NHS payslips are generated by ESR (Electronic Staff Record), the shared payroll and HR system used across the vast majority of NHS trusts, so while the exact layout varies slightly by trust, the core set of lines you'll see is genuinely consistent. If you've ever looked at your payslip and had no real idea what half the lines meant — or noticed the number change from one month to the next without a raise and wondered whether something's wrong — this guide walks through a typical NHS payslip line by line, in plain English.
Short answer
A typical NHS payslip moves through five broad stages: your earnings (basic pay, plus any enhancements for unsocial hours, overtime or High Cost Area Supplement), your gross pay (everything added together), your taxable pay (gross pay minus pre-tax deductions like your pension contribution), your deductions (Income Tax, National Insurance, pension contribution, and anything else like a student loan), and finally your net pay — what actually lands in your bank account. Understanding what sits in each stage is the key to making sense of the whole slip.
Once you know what each line means, check yours with the free NHS Payslip Checker: it flags lines that differ from what we would expect and works out which tax code your tax implies.
Earnings: what's actually being paid to you
This is usually the top section of the payslip, and it's where the most variation between months tends to show up.
Basic pay
Your basic pay reflects your contracted salary for your Agenda for Change band and pay point (or your agreed salary if you're not on Agenda for Change), pro-rated for the pay period. For most staff on a fixed full-time or part-time contract, this line is stable month to month — it only changes when you move pay point, get promoted, or a national pay award takes effect.
Unsocial hours and overtime enhancements
If your role involves nights, weekends, or bank holidays, you'll typically see one or more separate enhancement lines reflecting the extra percentage paid for those hours under Agenda for Change. Any genuine overtime — hours worked beyond your contracted hours — usually appears as its own line too, often at a different enhancement rate depending on when it was worked. These are the lines most likely to make your pay genuinely vary from month to month, since they depend on your actual rota rather than a fixed salary. Use the Unsocial Hours Calculator and the Overtime Calculator to check what a specific pattern of shifts should add to your basic pay, and compare that against what's actually showing on your slip.
High Cost Area Supplement (HCAS)
If you work in and around London, you'll usually see a separate High Cost Area Supplement line — a percentage addition to basic pay (subject to a minimum and maximum cash floor and ceiling) reflecting the higher cost of living in that area. It's shown separately from basic pay rather than folded into it, which occasionally confuses people checking their salary against a headline Agenda for Change figure quoted without HCAS. See our Agenda for Change pay scales guide for the current HCAS zones and rates.
ℹGross pay is the sum of everything above
Once every earnings line — basic pay, enhancements, HCAS, and anything else like an on-call allowance — is added together, that total is your gross pay for the period. It's the figure most people mean when they quote their "salary," but it's before any deductions at all, so it's always higher than what actually reaches your bank account.
Taxable pay: not quite the same as gross pay
Just below gross pay, you'll often see a separate taxable pay figure, and it's common to assume this is a mistake because it's usually slightly lower than gross pay. It isn't a mistake — certain deductions are taken before Income Tax is calculated, most significantly your NHS Pension Scheme contribution, because pension contributions attract tax relief at source. So your taxable pay is gross pay minus those specific pre-tax deductions, and it's the figure Income Tax is actually calculated on — not your gross pay.
Deductions: what comes off, and why
Income Tax and your tax code
Income Tax is calculated using your tax code, shown somewhere on your payslip (commonly near your personal details). In broad terms, your tax code represents how much of your income is tax-free before the remainder is taxed — the standard code for most people with one job and the standard Personal Allowance is currently 1257L, though the exact code can differ based on your personal circumstances (a second job, benefits in kind, or an adjustment from a previous tax year, for example). If your tax code looks unfamiliar or has changed without explanation, it's worth checking it directly with HMRC or your trust's payroll team — a wrong tax code is one of the more common genuine payslip errors, and it's usually simple to correct once flagged.
National Insurance
National Insurance (NI) is a separate deduction from Income Tax, calculated on its own basis, and it's what builds your entitlement to the State Pension and certain other state benefits over your working life. Most NHS staff are on NI category A, the standard category — you'll see the category letter shown alongside the deduction amount.
NHS Pension Scheme contribution
Almost all NHS staff are automatically enrolled into the NHS Pension Scheme unless they've actively opted out. Your contribution is shown as both a percentage and a cash amount, and the percentage is set by which contribution tier your actual annual pensionable pay falls into — it's tiered, not a flat rate for everyone. See our full NHS Pension Scheme 2015 explained guide for the current tier table and how your contributions actually build up your pension over time.
Student loan repayments
If you have an outstanding student loan and your income is above the relevant repayment threshold for your loan plan, a student loan deduction will appear as its own line, calculated automatically by payroll based on the plan type HMRC holds for you. If you believe you're on the wrong plan, or that deductions have started before you think they should have, that's a query for HMRC and the Student Loans Company as much as your trust's payroll team.
Other deductions
Depending on your trust and your own arrangements, you might also see lines for things like a Cycle to Work scheme repayment, car parking, union subscriptions (if paid via payroll deduction rather than directly), or a benefit-in-kind adjustment. None of these are universal — check anything unfamiliar rather than assuming it's standard.
Net pay: what you actually take home
After every deduction — tax, National Insurance, pension contribution, student loan, and anything else — what's left is your net pay, the amount actually paid into your bank account. This is usually shown prominently at the bottom of the payslip, sometimes alongside a running year-to-date total for gross pay, tax paid, and NI paid, which is worth keeping an eye on if you're trying to track your total earnings across the tax year.

Why your pay can vary month to month even on a fixed salary
Even nurses, AHPs and other staff on a stable band and pay point often see their net pay move up and down slightly between months, for entirely ordinary reasons:
- Different numbers of working days. Some months simply have more working days than others, which affects anything calculated on an hours or shifts basis.
- Shift pattern changes. If your rota includes a different mix of nights, weekends or on-call cover from one month to the next, your unsocial hours enhancement changes with it.
- Timing of a pay award. When a national pay award is confirmed partway through the year it applies to, it's common for backdated arrears to appear as a distinct lump in a later payslip, rather than the whole year's increase applying smoothly from the announcement date. Our 2026/27 pay rise guide explains how this has worked for the current award.
- One-off items. Overtime, an expenses reimbursement, or a one-off deduction (such as recovering an overpayment from a previous month) can all shift a single month's figure without reflecting any ongoing change.
What to do if something looks wrong
If a figure on your payslip genuinely doesn't add up — an enhancement you know you worked is missing, your tax code changed without explanation, or a deduction you don't recognise has appeared — the sensible first step is always your trust's own payroll team, usually reachable via ESR self-service or a dedicated payroll query inbox. Most issues are genuinely simple to explain or correct once you flag the specific pay period and line in question. If you raise it and don't get a satisfactory answer, or you think the response is wrong, your line manager can escalate on your behalf, and — if you're a union member — your trade union rep can pursue it more formally. See our guide to NHS staff representation for who can actually help with this kind of workplace issue and how to reach them.

Things worth double-checking periodically
You don't need to scrutinise every payslip line by line every month, but it's worth a periodic sense-check — particularly after any change to your role, hours, or personal circumstances:
- • Your tax code — check it still looks right, especially after a change of job, a second income, or a change in benefits
- • Your pension contribution rate — confirm the percentage matches the tier your actual annual pensionable pay falls into, particularly after a pay rise or a change in hours
- • Any recurring deduction you don't recognise — a subscription, scheme repayment, or benefit-in-kind adjustment you didn't set up or have forgotten about
- • Your year-to-date totals — a rough sanity check against what you'd expect to have earned and paid in tax so far this tax year
