HR and payroll for non-profit in the United Kingdom
Reviewed by Mellow Editorial Team, HR & payroll content team
Running HR and payroll for a non-profit in the UK follows the same fundamental legal framework as any other employer — PAYE, RTI, auto-enrolment, statutory leave — but the sector has specific pressures around funding cycles, volunteer management, and cost control that shape how you apply those rules in practice.
Your legal obligations are the same as any employer
Charitable or community status does not grant exemptions from employment law. If you pay staff, you must:
- Register as an employer with HMRC and operate PAYE from the first payday
- Submit a Full Payment Submission (FPS) on or before each payday under Real Time Information
- Pay employer National Insurance at 13.8% on earnings above the secondary threshold
- Enrol eligible workers into a qualifying pension scheme, contributing at least 3% of qualifying earnings
- Issue a P60 to every employee by 31 May and file P11D forms for any reportable benefits by 6 July
- Provide a minimum of 5.6 weeks statutory annual leave (28 days including bank holidays for a five-day week)
The Employment Rights Act 2025 also strengthens day-one rights for workers — meaning unfair dismissal protections and other entitlements apply earlier in the employment relationship. Non-profits are not exempt, and smaller charities sometimes discover this the hard way.
Funding cycles and payroll stability
Many non-profits run on project-based or grant funding, which creates a practical payroll problem: you may know a role is funded only for 12 or 18 months, yet employment law still applies in full. Fixed-term contracts are legitimate, but misusing them — renewing repeatedly without objective justification — creates risk.
When a funding round is delayed or a grant ends, redundancy processes still apply. Statutory redundancy pay, notice periods, and consultation requirements do not disappear because the money ran out. Build a small payroll reserve if you can, and build redundancy costs into grant applications as a legitimate project expense. Many funders accept this when it is framed correctly.
If you employ staff across multiple grants simultaneously, you also need a clear cost-allocation method so that payroll costs are reported accurately to each funder. HMRC does not care how your funding is structured — your PAYE liability is calculated on total earnings regardless.
Volunteers: not employees, but not entirely separate
Volunteers are a cornerstone of the non-profit sector and should not appear on your payroll. Paying volunteers a "thank you" that goes beyond genuine out-of-pocket expense reimbursement can create an employment or worker relationship in law, which triggers PAYE, National Insurance, and minimum wage obligations.
The distinction matters. Reimbursing a volunteer's travel and lunch costs is fine. Paying them a flat weekly sum — even if you call it an "allowance" — risks reclassifying the relationship. If you offer regular shift patterns, supervision, and a requirement to turn up, a tribunal may find a worker relationship exists regardless of what your documents say.
Keep volunteer expense policies written down, require receipts, and review the arrangements if any volunteer's role becomes more structured over time.
Managing low pay and the National Living Wage
Non-profits employ a high proportion of part-time and lower-paid workers, particularly in care, community, and support services. The National Living Wage is a legal floor, not a guideline, and applies regardless of your charitable purpose or funding constraints.
If your grant funding does not cover wage increases when the rate rises, that is a funding gap to address — it is not a legal defence. Build wage uplifts into multi-year funding proposals and review salary bandings every April when the rate changes.
Where staff receive benefits in kind — such as a car or private medical insurance — these must be reported on a P11D by 6 July and may attract Class 1A National Insurance. Small non-profits sometimes overlook this because benefits are less common, but the obligation applies even if the benefit was provided from donated goods or services.
Pension auto-enrolment and staff turnover
Auto-enrolment applies to all eligible workers aged 22 to state pension age earning above the earnings trigger for the relevant tax year. In the non-profit sector, where short-term contracts and part-time roles are common, you need a process for assessing new starters promptly and re-enrolling staff who previously opted out at three-yearly intervals.
The minimum employer contribution is 3% of qualifying earnings. Employees contribute a minimum of 5%. These figures apply whether the work is funded by grant, trading income, or donations.
High turnover — common in underfunded parts of the sector — means more frequent enrolment assessments, more opt-outs to process, and more pension administration overall. A payroll system that automates these assessments reduces the risk of missing a deadline and incurring a penalty from The Pensions Regulator.
HR policies that matter most in this sector
Beyond payroll mechanics, non-profits should pay particular attention to:
Safeguarding and DBS checks. If your work involves children or vulnerable adults, Disclosure and Barring Service checks are often mandatory. Keep a log of check dates and renewal schedules — this is both a legal and governance requirement.
Flexible and part-time working. A large proportion of non-profit staff work part-time. Ensure contracts reflect actual hours accurately, that holiday entitlement is calculated correctly on a pro-rata basis, and that part-time workers are not treated less favourably than comparable full-time staff.
Grievance and disciplinary procedures. The Employment Rights Act 2025 makes it more important than ever to have documented, consistently applied procedures. Smaller charities sometimes operate informally until a dispute arises — by which point the absence of written procedures becomes a liability.
