How to become a locum dietitian in the UK: HCPC protected title, BDA membership, NHS agency vs private clinics, and the dietitian vs nutritionist distinction.
At a glance | Regulator
HCPC registration as a Dietitian requiredA locum dietitian covers clinical work for the organisations that need them, one session at a time, instead of holding a single salaried post. Depending on the profession and the booking that can mean self-employment, or PAYE through an agency, a staff bank or an umbrella company: the steps below say which is usual. This guide walks through everything you need to do to start, in order, and the common pitfalls that catch people in their first year.

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.
Most dietitians should complete 1 to 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.
UK private dietetic demand concentrates in specific niches: gastroenterology / IBS (the biggest private niche, £90 to £160/session), paediatric allergy (growing fast), oncology, renal, sports nutrition. General weight management is crowded and low-margin.
Globe Locums, Sanctuary Personnel, Your World Healthcare cover most NHS locum dietitian work. Agency Band 7 rates sit £34 to £42/hr, Band 6 £28 to £38/hr. Dietetics is a smaller AHP locum market than OT or physio.
BDA Freelance Dietitians Group membership connects you to peer support and referrals. ICO data protection registration is required for private practice and is easily missed (check the current fee at ico.org.uk). Build a website that clearly states "Dietitian": don’t muddy it with "Nutritionist" language.
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.
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 to £35,000/year part-time) are higher value but harder to land and client-specific.
