How to become a locum dietitian in the UK
How to become a locum dietitian in the UK: HCPC protected title, BDA membership, NHS agency vs private IBS / allergy / sports clinics, and the dietitian vs nutritionist distinction.
A locum dietitian 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.
Step by step.
7 steps- 01
HCPC + BDA membership
HCPC registration is mandatory. "Dietitian" is a protected title. Critically, "Nutritionist" is NOT HCPC-protected – anyone can legally use that title. This distinction matters for marketing, fee defensibility, and professional positioning. BDA membership is optional but standard.
- 02
Complete NHS preceptorship
Most dietitians should complete 1–2 years post-qualification in an NHS acute or community rotational before going pure locum. Specialism maturity is what drives rate progression, and the broad exposure helps.
- 03
Pick a specialism
UK private dietetic demand concentrates in specific niches: gastroenterology / IBS (the biggest private niche, £90–£160/session), paediatric allergy (growing fast), oncology, renal, sports nutrition. General weight management is crowded and low-margin.
- 04
For NHS locum: agencies + NHSP
Globe Locums, Sanctuary Personnel, Your World Healthcare cover most NHS locum dietitian work. Agency Band 7 rates sit £34–£42/hr, Band 6 £28–£38/hr. Dietetics is a smaller AHP locum market than OT or physio.
- 05
For private: BDA Freelance Group + ICO registration
BDA Freelance Dietitians Group membership connects you to peer support and referrals. ICO data protection registration is required for private practice (£40–£60/year, easily missed). Build a website that clearly states "Dietitian" – don’t muddy it with "Nutritionist" language.
- 06
Specialism accreditation
Monash FODMAP training is the default for IBS clinic work. Paediatric allergy modules for children’s allergy practice. These accreditations directly unlock referral flow from GPs and gastroenterologists.
- 07
Digital platforms and sports contracts
Oviva (digital diabetes), Second Nature, and Liva hire dietitians on per-case or hourly contracts. These cap your hourly rate and are profitable only at volume. Professional sports retainers (£8,000–£35,000/year part-time) are higher value but harder to land and client-specific.

First-year pitfalls.
- !Not distinguishing "Dietitian" from "Nutritionist" in marketing. Weakens fee defensibility and professional standing
- !Under-pricing private sessions compared with US and Australian markets. UK dietitians habitually undersell
- !Sports nutrition contract disputes when athletes break protocols
- !Digital platform contracts capping hourly rate. Profitable at volume only
- !Supplement or product endorsements that breach HCPC standards of conduct. Deregistration risk
