Volunteer Expenses in a UK Rescue: The Line Between Reimbursement and Pay

A UK rescue may reimburse a volunteer for what they actually spent, and almost nothing beyond that. Section 44 of the National Minimum Wage Act 1998 removes the minimum wage only where the volunteer receives no monetary payment except expenses actually incurred — or reasonably estimated — in performing their duties, and no benefit in kind beyond subsistence or reasonable accommodation.¹

What section 44 requires

Two conditions both have to hold. On money, the volunteer must receive no monetary payments of any description, except expenses actually incurred in performing their duties or reasonably estimated as likely to have been. On benefits in kind, none, other than some or all of their subsistence, or accommodation reasonable in the circumstances.¹ A later amendment widened the first limb: a cost incurred in order to enable the volunteer to perform their duties, reasonably so incurred and not an accommodation cost, counts as incurred in the performance of those duties — broader than costs run up during the shift itself.¹ Training is treated as a benefit in kind, except training whose sole or main purpose is improving the volunteer's ability to do the work they agreed to do.¹

Two definitions matter to small groups. "Receive" means receiving in respect of, or otherwise in connection with, the employment — whether or not under the terms of it,¹ so an informal thank-you nobody wrote down still counts. And the exemption is not limited to registered charities: it also covers a "voluntary organisation", defined as a body established only for charitable, benevolent or philanthropic purposes but which is not a charity.¹ An unregistered rescue can sit inside section 44 on that footing.

Payments that stay inside the exemption, and payments that do not

The flat weekly payment is the row that catches people, because it is easier than collecting receipts from eleven foster homes. The sector body GOV.UK signposts on volunteer law is blunt: anything above actual expenses may be treated as consideration, and calling it a stipend, a sessional payment or an honorarium does not change that.³ That is guidance rather than statute, but it reads the same test the statute sets.

Mileage rates changed in April 2026

Approved mileage allowance payments for cars and vans rose to 55p for the first 10,000 business miles in a tax year, and 25p for each mile above that, from the 2026 to 2027 tax year. They had been 45p and 25p since 2011. Motorcycles are 24p and bicycles 20p.⁴

HMRC's position is that reimbursing a volunteer driver is not usually liable to Income Tax, because it repays what was spent; tax bites only on a profit, and no National Insurance is due on such a profit.⁵ Two details get missed. The rates apply to the total miles driven across every organisation the person volunteers for, not per rescue, so a driver who runs transport for you and for a second group has one combined 10,000-mile band. And a driver who does make a profit must register for Self Assessment by 5 October of the tax year following the one in which they made it, and keep receipts for at least two years.⁵

One rate does not reach rescue work: the 5p passenger payment is for carrying fellow employees on journeys that are also work journeys for them.⁴ A van full of dogs is not that.

Volunteer agreements, minimum hours and the words you use

GOV.UK's position is that a volunteer agreement is not compulsory and does not form a contract between the volunteer and the organisation.⁶ That describes the ordinary case rather than guaranteeing the outcome. Sector guidance is clearer about the limit: a clause stating that no legally binding relationship is intended is worth including, but it "is not an easy get-out clause", and a tribunal or court would ignore it where the arrangement is clearly contractual.³ The label on the document does not decide the question; what the parties exchange does.

The same guidance points at three habits that push a rescue the wrong way: requiring a minimum time commitment rather than describing a reasonable expectation, borrowing employment vocabulary such as "contract", "job" and "requirements" instead of "agreement", "role" and "hopes", and letting a discretionary perk become customary.³ None of that is law, but it is cheap to follow.

What you have to be able to produce, and who now asks for it

Failing to pay the minimum wage, or faking payment records, is a criminal offence, and the employer carries the burden of proving compliance. GOV.UK's list of records an employer may need to keep includes, in terms, documents showing why a worker is not entitled to the minimum wage; pay records generally have to be kept at least six years where created on or after 1 April 2021.⁷ For a rescue relying on section 44, receipts and claim forms are not bookkeeping tidiness — they are the evidence the exemption applied.

The body asking has changed, though not the test. The Fair Work Agency now holds statutory responsibility for minimum wage enforcement, with HMRC delivering it under contract; the transfer of HMRC's minimum wage staff is scheduled for April 2027, and holiday pay enforcement is expected to begin during 2027 rather than now.⁸ As of September 2026, nothing in that reorganisation alters section 44.

For most small rescues the exposure is theoretical, because most really are reimbursing receipted costs. The risk concentrates in one place: the long-serving foster carer or trapper doing what amounts to a part-time job for a round-number payment. The choice there is to move them onto receipted reimbursement or accept that they may be a worker — and the April 2026 rates, £12.71 an hour at 21 or over and £10.85 at 18 to 20, are the measure of the second option.⁹
