The Isle of Wight Trust v HMRC Case
The case of Isle of Wight NHS Trust v HMRC addressed the VAT treatment of locum services supplied to NHS organisations and provided helpful clarification on how exemptions apply to medical deputising arrangements.
Under UK VAT legislation, the “provision of a deputy for a person registered in the register of medical practitioners” is treated as an exempt supply. This exemption reflects the intention that medical services provided by qualified practitioners are not subject to VAT, as they are considered healthcare services for the protection and maintenance of human health.
In this case, the locums in question were qualified medical practitioners who performed the same duties as the doctors they temporarily replaced. On that basis, the NHS Trust treated these supplies as exempt from VAT.

HMRC’s arguments
HMRC took a more restrictive view of the exemption. It argued that, when interpreted in line with the principal VAT Directive under EU law, the exemption only applied to personal medical services provided directly by the deputy doctor. According to HMRC, the exemption did not extend to the broader supply of staff under a deputising arrangement where a business provides doctors to the NHS.
Additionally, HMRC contended that the exemption was limited to circumstances where the deputy was directly substituting for a named general practitioner. In other words, HMRC argued that only a one-for-one replacement of an identified GP would qualify for exemption, not a general supply of locum doctors to cover duties more broadly.
The Tribunal’s findings
The Tribunal rejected HMRC’s interpretation and accepted the arguments put forward by the NHS Trust. It found that the wording of the UK legislation was clear and unambiguous. The exemption applied to the provision of a deputy for a person registered as a medical practitioner, and this included locum doctors provided to fulfil those functions, regardless of whether a named GP was specified.
The Tribunal therefore ruled that the supplies of medical services made by the NHS Trust were exempt from VAT. The decision reinforced that the exemption applies to the functional role of the medical practitioner being replaced, rather than to the contractual or administrative structure through which the locum is provided.
Wider implications and next steps
This case was designated as a lead case for a number of similar disputes between HMRC and NHS bodies. The Tribunal’s decision offers clarity for healthcare providers and staffing agencies supplying locum doctors, but it also highlights the continuing tension between domestic VAT exemptions and their interpretation under EU principles.
Given the potential revenue implications, it is expected that HMRC may seek to appeal, meaning that the issue could remain unresolved for some time. In the meantime, NHS organisations and suppliers of locum services should review their arrangements to confirm that their VAT treatment aligns with the Tribunal’s findings and to assess any potential exposure should HMRC’s position ultimately prevail on appeal.
