How to become a locum dentist in the UK

A locum dentist covers clinical work on a session-by-session basis for the organisations that need them, as a self-employed professional rather than a salaried employee. This guide walks through everything you need to do to start, in order, and the common pitfalls that catch people in their first year.

1. 01

   GDC registration + DFT completion

   GDC registration is mandatory. UK-qualified new dentists must complete Dental Foundation Training (England) or the equivalent Vocational Training (Wales, Scotland, Northern Ireland) before being issued an NHS performer number. Overseas-qualified dentists go through equivalent pathways. Locum work on the NHS is impossible without DFT/VT or equivalent.

2. 02

   Apply for an NHS Performer Number

   Apply through NHS Business Services Authority’s Compass system for England. Scotland, Wales, and NI run their own equivalents. Budget 6–12 weeks. If you’re planning to work only privately, skip this initially – but most locum dentists do some NHS work.

3. 03

   Secure indemnity before any clinical work

   Dental Protection (MPS), MDDUS, DDU (MDU), or BDA Indemnity are the four options. Indicative locum premiums £2,500–£8,000/year depending on scope, claims history, and specialty (implants, endo, oral surgery push premiums hard); reviewed May 2026, verify with the provider for a current quote. Check run-off cover before switching providers – gaps here are catastrophic.

4. 04

   Pick your NHS / private / mixed mix

   UDA-linked NHS work pays £13–£16 per UDA typically, £17–£22 in underserved areas with recruitment premium. Private associate work pays 40–50% of gross (locum nets £320–£1,000/day at typical gross). Specialist locums (endo, perio, oral surgery, implants) earn £800–£1,800/day.

5. 05

   Register with dental agencies and corporate groups

   Dental Elite, MyLocum Manager, and Apollo Dental are the main agencies. Corporate groups (mydentist, Bupa Dental, Rodericks, Portman) usually hire locums direct without an intermediary. Register with a mix.

6. 06

   Review any associate agreement carefully

   HMRC has been scrutinising dental associate self-employment since 2022–2024. The old BDA Memorandum protection has weakened. Your agreement must reflect genuine self-employment: substitution rights, own materials where applicable, own hours, own patients. Get an accountant familiar with BDA Memorandum to review.

7. 07

   Plan for tax, pensions, and income protection

   Associate locums are usually sole trader or Ltd Co. Budget 30% for tax + Class 4 NI. Income protection insurance is not optional – dental careers are frequently cut short by repetitive strain or eye strain. Add NHS pension if NHS-performing.
