"Wholly & exclusively"
The core test

The golden rule

Wholly and exclusively

To be tax-deductible, an expense must be incurred wholly and exclusively for business purposes. Mixed personal/business use (like a phone used for both) is normally apportioned rather than fully claimed or fully disallowed.

Common allowable expenses by role

Self-employed (locum GPs, hospital locums, dental associates)

GMC/GDC registration fees, medical or dental indemnity, professional subscriptions (BMA, BDA, royal college), CPD courses, travel between different sites (not ordinary commuting to a single regular base), equipment, accountancy fees.

Salaried / employed (salaried GPs, hospital doctors, some dentists)

More restricted — HMRC's rules for employees are stricter than for the self-employed. Professional subscriptions and some CPD costs may qualify for tax relief even as an employee, but many locum-style claims don't apply.

FAQ

Specific protective clothing or uniforms can sometimes qualify, but everyday clothing — even if only worn for work — generally does not meet HMRC's test. This is a genuinely grey area worth checking with an accountant for your specific situation.

Receipts or invoices for every claimed expense, and ideally a simple log of business mileage/travel with dates and purposes. HMRC can request evidence going back several years, so keep digital copies rather than relying on paper receipts fading in a drawer.
