How to become a locum dentist in the UK
How to become a locum dentist in the UK: GDC registration, NHS Performer Number via Compass, associate agreements, indemnity via Dental Protection, and the HMRC self-employment scrutiny landscape.
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.
Prerequisites: current GDC registration as a Dentist, and the right to work in the UK. Regulator: General Dental Council (GDC).
Typical UK locum dentist rate (2026): NHS UDA £13–£16 (£17–£22 in underserved areas), private associate 40–50% of £800–£2,000 gross, specialist £800–£1,800/day.
Step-by-step
- 1
GDC registration + DFT completion
GDC registration is mandatory. UK-qualified new dentists must complete Dental Foundation Training (DFT) before being issued an NHS Performer Number. Overseas-qualified dentists go through equivalent pathways. Locum work on the NHS is impossible without DFT or equivalent.
- 2
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
Secure indemnity before any clinical work
Dental Protection (MPS), MDDUS, DDU (MDU), or BDA Indemnity are the four options. Locum premiums £2,500–£8,000/year depending on scope, claims history, and specialty (implants, endo, oral surgery push premiums hard). Check run-off cover before switching providers – gaps here are catastrophic.

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
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
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
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.
Documents to have ready
- GDC registration certificate
- NHS Performer Number confirmation (if NHS-performing)
- Dental Foundation Training (DFT) completion certificate
- Indemnity certificate with clearly stated scope
- Hepatitis B status with satisfactory titre
- Enhanced DBS
- Immunisations (Hep B, MMR, Varicella, TB)
- Radiography certificate (IRR17 / IR(ME)R)
- Safeguarding Level 2 / 3
- References from last two principals
Keep expiry dates tracked. Sessional sends reminders 30 days before each document lapses.
Common first-year pitfalls
- Indemnity run-off gap when switching providers. Occurrence-based cover does not always port cleanly
- Associate agreement terms that fail HMRC self-employment tests. Substitution, materials, and hours language matters
- UDA underperformance at year-end triggering clawback. You were not the contract holder but the agreement penalises you
- Hepatitis B titre gaps blocking bookings at short notice
- Endodontic / periodontal / oral surgery scope creep without notifying indemnity
Keep the admin painless from day one
Sessional tracks every session, invoice, expense and document so you spend your evenings with family, not spreadsheets. Free to start.
