When NHS pay rises are announced, they’re backdated to 1 April — meaning staff receive months of arrears as a lump sum. Our NHS Back Pay Calculator shows your exact net take-home amount after tax, National Insurance, and pension deductions.

The 2025/26 pay award (3.6%) was processed in August 2025, with staff receiving four months of backdated pay. Whether you’re verifying your payment or planning for the upcoming 2026/27 award, this calculator provides accurate estimates for all Agenda for Change bands across England, Scotland, Wales, and Northern Ireland.

How NHS Back Pay Works

NHS pay awards are negotiated annually by trade unions including the Royal College of Nursing (RCN), Unison, and Unite, then reviewed by the NHS Pay Review Body (NHSPRB) before government approval. Awards are typically confirmed after the financial year begins in April, creating a backdating period.

The result? A lump sum payment covering the difference for each month since April.

Your gross back pay follows this formula:

(New Annual Salary − Old Annual Salary) ÷ 12 × Months Backdated = Gross Arrears

However, your net back pay is lower because HMRC applies deductions through PAYE.

2026/27 Pay Round: Current Status

The NHS Pay Review Body (NHSPRB) is currently reviewing written evidence for the 2026/27 pay round. The government’s remit letter confirms that a valued, motivated, and skilled NHS workforce is essential to delivering the 10 Year Health Plan.

Key considerations for 2026/27 include:

• All pay must be funded from departmental budgets with no additional funding available
• Productivity and efficiency targets following ICB cost reductions of 50%
• Workforce context following the abolition of NHS England
• Recruitment and retention data

Announcements are expected in spring 2026, with any backdated payment likely processed in August 2026.

What Deductions Apply to Back Pay?

Your lump sum arrears are taxable income. HMRC processes them through PAYE alongside your regular salary.

Income Tax

Tax on backdated pay is due on the earliest of two dates: when payment was received or when you became entitled to it.

Important: A large lump sum could temporarily push you into a higher tax bracket for that pay period.

National Insurance Contributions

For retroactive pay rises agreed late, National Insurance is treated as earnings in the period it is actually paid. It is added to the current month’s pay and calculated using current rates and thresholds.

For corrections of payroll errors, NICs are calculated as if paid on time, allocated to the original period to ensure correct NI allowances.

The current rate is 8% on earnings between £12,570 and £50,270.

NHS Pension Contributions (From 1 April 2025)

Back pay is pensionable. Member pension contributions must be checked for backdated pay awards. Any increase in actual annual pensionable pay may push staff into the next contribution tier.

Scotland Contribution Rates:

Note: If your back pay pushes your annual pensionable pay into a higher tier, arrears of contributions will be payable at the revised rate for all pensionable pay from 1 April. Some members may move to a lower contribution rate, and overpaid contributions must be returned.

Student Loan Repayments

Student loans are deducted based on your plan type:

High Cost Area Supplements (HCAS)

Staff working in London or the surrounding areas receive HCAS supplements, which are also backdated when pay rises take effect.

Example: Band 5 Nurse with Inner London HCAS

The HCAS increase is calculated on your new pay rate and backdated alongside your basic pay arrears.

Back Pay by Agenda for Change Band

Band 2 & Band 3 (Healthcare Assistants, Support Workers)

Healthcare assistants, domestic staff, and clinical support workers on Band 2 earn £24,465 in 2025/26. Band 3 roles include HCAs performing vital signs observations, earning £24,937–£26,598. With four months backdated at 3.6%, gross arrears typically range from £280–£350 before deductions.

Hourly Pay Rates 2025/26

For staff calculating overtime or bank shifts, here are the standard hourly rates:

Hourly pay is calculated from a 37.5-hour standard week, set by Agenda for Change in 2004. Before 2004, the standard working week was 39 hours.

Part-Time Staff Back Pay Calculations

Part-time NHS staff receive pro-rata back pay based on Full-Time Equivalent (FTE) hours.

Example Calculation:

• You work 22.5 hours weekly (0.6 FTE)
• Full-time gross back pay = £400
• Your gross back pay = £400 × 0.6 = £240

Our calculator includes an FTE slider to adjust calculations for any contracted hours between 0.1 and 1.0. Weekly pay adjusts automatically based on hours entered.

Who Is Excluded from AfC Back Pay?

Not all NHS workers receive Agenda for Change back pay:

Staff employed directly by NHS organisations on an Agenda for Change contract are usually automatically eligible. Those employed by GP practices or providing contracted services may not be automatically eligible.

Pay Progression and Back Pay

The pay progression system came into effect 1 April 2019 for new starters or those promoted to a new role. Understanding how progression interacts with back pay is essential.

Pay Step Requirements

To progress to your next pay step, you must demonstrate:

• Successful appraisal within the last 12 months
• Not in a formal capability process
• No live formal disciplinary sanction
• Completed all statutory and mandatory training
• If a line manager has completed all staff appraisals

Pay Step Timing by Band

For Bands 8c, 8d, and 9, once at the top of the band, 5% or 10% of basic salary becomes re-earnable annually based on meeting required standards.

Enhancement Payments and Back Pay

Unsocial hours payments, night shift premiums, and weekend enhancements are also backdated when pay rises take effect. These are calculated on your new enhanced rates.

Our calculator allows you to add overtime hours, night shifts, or weekend enhancements. The tool applies NHS Agenda for Change rules to estimate your enhanced pay accurately.

How to Verify Your Back Pay

Check your back pay on your payslip via ESR (Electronic Staff Record) or your Trust’s self-service portal. Your payslip should show:

• Gross arrears as a separate line item
• Tax deduction on the lump sum
• NI deduction
• Adjusted pension contribution
• Student loan deduction (if applicable)
• Net back pay amount

If discrepancies exist, contact your employer’s payroll department. For exact figures, your employer’s payroll will have the final say.
