How to become a locum dental hygienist in the UK

A locum dental hygienist 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 as DH (and DT if qualified)

   GDC registration is mandatory. Most practising hygienist/therapists are dual-registered as Dental Hygienist and Dental Therapist, which widens employable scope. A Performer Number is not required for hygienists – that applies only to dentists.

2. 02

   Understand direct access scope

   Since 2013 and under ongoing GDC guidance, hygienists and therapists can see patients directly without a dentist’s prescription for scaling, polishing, oral health instruction, fluoride application, and similar. Hygienists and therapists are also competent to prescribe, take, process, and interpret radiographs within their scope of practice (no dentist direction required). Restorative work and treatment planning still typically need dentist direction. From 26 June 2024, hygienists and therapists who are competent can administer local anaesthetic under medicines exemptions without a dentist’s prescription, although competency-based post-registration training is still expected.

3. 03

   Secure indemnity

   Dental Protection, MDDUS, DDU, or BSDHT-linked cover. Indicative premiums (reviewed May 2026, verify with provider) typically £400–£1,200/year, considerably cheaper than dentist indemnity. If you’re practising independently under direct access, check for specific endorsement.

4. 04

   Complete local anaesthetic training

   If your qualification didn’t include local anaesthetic post-registration training, completing it expands employability significantly. Many practice owners only book hygienists who can administer LA themselves. Radiography and airflow training open more doors still.

5. 05

   Find work through informal networks

   Hygienist locum work is more informal than dentist locuming. BSDHT Jobs, LinkedIn, and "Dental Hygienist Locum UK" Facebook groups are where most of the market sits. Dental Elite, Apollo Dental, and MyLocum Manager run hygienist desks alongside dentist work.

6. 06

   Negotiate percentage agreements carefully

   The dominant model is 40–50% of gross treatment value. Typical day gross is £600–£1,400, so net sits £240–£700/day. Empty books on the day mean £0. Book quality matters more than headline percentage. Central London and affluent home counties command a premium (up to £800–£1,000/day net at premium practices).

7. 07

   Keep your own patient records separately

   If you leave a practice, the practice keeps its records. Your own notes (properly structured, privacy-compliant) are what you carry forward. They also matter medico-legally.
