Volunteer Expenses: What UK Charities Can and Can’t Reimburse
Getting volunteer expenses wrong in either direction causes problems: reimburse too little and you quietly exclude anyone who cannot afford to be out of pocket, reimburse the wrong way and you risk turning volunteers into employees by accident.
Published July 2026UK law draws a clear, deliberate line between reimbursing a volunteer for money they have genuinely spent and paying them for their time. Covering actual, reasonable out-of-pocket costs — travel to and from a volunteering session, meals bought while volunteering away from home, specific materials bought on the charity’s behalf — is entirely legitimate and does not affect a person’s status as an unpaid volunteer. Paying a flat sum regardless of actual cost incurred, or paying anything that functions as a reward for time given rather than a genuine reimbursement, risks being treated as payment, which can drag a volunteer arrangement into employment law territory, including minimum wage obligations, entirely by accident.
What is safely reimbursable
The safest and most common category is travel: mileage for driving a personal car to a volunteering shift, the cost of a bus or train fare, or a parking fee paid on the day. Charities typically use a standard mileage rate, often aligned with HMRC’s approved mileage allowance figures used for employee travel, to keep reimbursement consistent and defensible rather than negotiating a different rate with each volunteer. Meals and subsistence bought while volunteering, particularly on a long shift away from home such as an all-day event like Candles on the Cobb itself, are also standard, provided the amount reflects a reasonable actual cost rather than a generous round-figure allowance unrelated to what was actually spent.
Receipts, and why they matter more than they seem to
Requiring receipts, or at minimum a simple expense claim form recording what was spent and why, is not bureaucratic box-ticking; it is the paper trail that demonstrates a payment was a genuine reimbursement of actual cost rather than disguised pay. A charity that hands volunteers a flat cash sum with no record of what it was actually for has a much weaker position if ever questioned by HMRC or the Charity Commission about whether its volunteers are, in substance, being paid. Keeping this record-keeping simple — a one-page form, a shoebox of receipts, a basic spreadsheet — is entirely sufficient for a group the size of most Dorset community charities; the point is that some record exists, not that the system needs to be elaborate.
What crosses the line
Paying a volunteer a set sum per shift regardless of what they actually spent, offering meaningful non-cash benefits tied to hours worked, or promising a future reward contingent on continued volunteering are all things that risk being read as payment in exchange for work, potentially triggering minimum wage and other employment obligations the charity almost certainly did not intend to take on. This does not mean volunteers cannot be thanked in other ways — a modest thank-you gift at the end of a season, unrelated to specific hours worked, sits in a different and generally safer category — but any scheme that starts to resemble pay calculated by time given needs proper advice before it is put in place, not after a problem has already arisen.
Writing it down as a policy
Groups that rely on volunteers regularly, rather than for a single annual event, benefit from a short written expenses policy: what is reimbursable, what rate applies to mileage, what receipts are needed, and who signs off claims. This does two things at once — it protects the charity by demonstrating a consistent, defensible approach, and it protects volunteers by making clear in advance what they can expect to be covered for, rather than leaving it to an awkward conversation after the fact. GOV.UK publishes guidance on volunteering, pay and expenses aimed at both volunteers and the organisations that involve them, and it is a sensible reference point for any group drafting its own policy from scratch.
