What a nutritional therapist brings to a client's care
The bodies that oversee the profession describe it in similar, concrete terms. BANT defines nutritional therapy as "the application of nutrition and lifestyle medicine sciences in the promotion of health, peak performance and individual care", and says registered nutritional therapists recommend personalised, science-based nutrition and lifestyle medicine programmes built around the client's goals and dietary preferences.
The advertising regulator's own description is just as practical. In its AdviceOnline entry on nutritional therapy (March 2022), CAP describes nutritional therapists as using "a range of approaches, tailored to the individual", including diet and lifestyle modification, supplement recommendation and awareness of environmental factors that may affect overall health and wellbeing.
CNHC describes the consultation itself: a health and nutrition questionnaire beforehand (many practitioners now run that intake questionnaire online), a first appointment of 60 to 90 minutes covering history, medication, supplements, lifestyle and diet, and follow-ups generally after four weeks. It adds that nutritional therapy is relevant both to people who want to improve their wellbeing and to people with chronic conditions who choose to work with a nutritional therapist alongside their other healthcare professionals.
The UK framework: voluntary registers, protected titles nearby
Nutritional therapy is not one of the professions regulated by statute in the UK. The Health and Care Professions Council (HCPC) regulates fifteen professions, dietitians among them, and lists "dietitian" and "dietician" as protected titles. Nutritional therapist and nutritionist do not appear on that list.
Instead, the profession has a voluntary register with official standing. CNHC states that it "was set up with government support to protect the public by providing a UK voluntary register of health practitioners", and that its register is approved as an Accredited Register by the Professional Standards Authority for Health and Social Care (PSA), a body accountable to Parliament. The PSA first accredited CNHC in 2013. CNHC registers eighteen disciplines, including nutritional therapy and naturopathy.
A third register sits alongside: the Association for Nutrition's UK Voluntary Register of Nutritionists (UKVRN), whose registrants use RNutr (Registered Nutritionist) or ANutr (Registered Associate Nutritionist). It is built around nutrition science degrees and specialisms such as public health, food or sport; nutritional therapy is not one of its listed areas.

CNHC registration: what it takes
CNHC registration puts you on a PSA Accredited Register. The criteria are short:
- Training. A programme that meets, as a minimum, the National Occupational Standards and the CNHC Core Curriculum for nutritional therapy. Courses delivered entirely by distance learning do not meet CNHC requirements. An alternative route exists for practitioners with at least three years of relevant experience and relevant training, assessed against the same standards.
- Insurance. Current professional indemnity insurance to practise in the UK, with evidence on request.
- Conduct. A declaration that you have no unspent conviction or conditional caution, and agreement to be bound by the CNHC Code of Conduct, Ethics and Performance.
- CPD. A minimum of 15 hours a year for a single discipline, of which 10 must relate directly to that discipline.
- Right to work. The right to work in the UK, or confirmation that your work with UK-based clients will be entirely remote.
Fees. The annual registration fee is £75 for your first discipline, then £10 for each additional discipline up to four.
BANT membership: the professional body
BANT, the British Association for Nutrition and Lifestyle Medicine, is the not-for-profit, volunteer-run professional body for nutrition practitioners. Its practising membership builds on CNHC rather than replacing it: "CNHC registration is compulsory for Full Practising Members of BANT."
What full practising membership (MBANT) requires:
- An NTEC-accredited nutritional therapy qualification with clinical training. For applicants since 1 September 2020, that means a BSc (Hons) or higher from a recognised university plus the NTEC-accredited qualification.
- CNHC registration (or HCPC registration for a dietitian).
- Professional indemnity insurance for your nutritional therapy practice.
- At least 30 hours of CPD a year, logged on BANT's system.
- Compliance with the CNHC Code and the BANT Professional Practice Handbook.
What it costs. Full membership is £165, with a £145 renewal. Provisional membership (£150) covers HCPC-registered dietitians and practitioners trained overseas or on a course BANT does not recognise, after BANT's external portfolio and CNHC registration. Practitioners with a nutritional therapy qualification and more than three years in clinical practice can use BANT's portfolio route.
Where NTEC fits. The Nutritional Therapy Education Commission is an executive agency of BANT. It accredits courses against the Nutritional Therapy Core Curriculum and the National Occupational Standards, and BANT states that NTEC-accredited courses give direct entry onto the CNHC register.
Scope of practice: what you do, and where the line sits
The law does not define a scope of practice for complementary therapists, as CNHC's own Code points out. In practice, the Code you sign up to and the advertising rules set it, and together they draw a clear, workable picture.
What sits squarely within your work
Personalised diet and lifestyle programmes, supplement recommendations, and support for overall health and wellbeing. The CNHC Code also lets you give clients accurate information on the possible effects of their prescriptions, on how they might affect the care you plan, and on over-the-counter medication.
When you recommend supplements, the Code's guidance on conflicts of interest applies: your choice of products, and the price you charge if you sell them yourself, must be in the client's best interests, and you should tell clients about any interest you have in an organisation that sells the products you recommend. That applies whether you run your own supplement shop or recommend through a dispensary, and it is one reason many practitioners prefer multi-brand protocols chosen on formulation.
Where the line sits
- Medical advice. CNHC states that practitioners "never recommend nutritional therapy as a replacement for medical advice" and refer any client with red flag signs or symptoms to their medical professional.
- Prescribed treatment. Under the CNHC Code, you must not advise a client to stop medication or treatment prescribed or recommended by a statutorily regulated healthcare professional.
- Competence. You work within the limits of your own knowledge and skills, and seek advice, co-manage or refer when a case goes beyond them.
- Titles. No title or qualification may be used in a misleading way; anyone using "Doctor" makes clear they are not a registered medical practitioner unless they are on the GMC register.
Working alongside the GP
The Code gives you a practical route. If you have well-founded concerns about a treatment another professional has prescribed, you advise the client to discuss it with that professional and, with the client's consent, you can contact their GP. Co-managing a client with another healthcare practitioner is listed as a normal option, and CNHC expects nutritional therapists to communicate with the other providers involved in a client's care. A short letter to the GP, sent with consent, is often the simplest way to make that collaboration real.
Marketing your practice in the UK: what CAP lets you say
The CAP Code applies to your website, social media and leaflets, and CAP's advice on nutritional therapy works well as a checklist.
Likely to be acceptable. Claims that nutritional therapy can have a positive overall impact on health and wellbeing. Claims that it can help people who want to manage their weight better, or to devise a diet better suited to an active or sporting lifestyle.
Where you need more care. Claims to treat or prevent a disease or medical condition require robust clinical evidence under rule 12.1. Claims about conditions that need medical supervision, which CAP lists as including anaemia, diabetes, high blood pressure, infertility, gastric ulcers, metabolic diseases and obesity, could be seen to discourage essential treatment unless the care takes place under the supervision of a suitably qualified health professional (rule 12.2). CAP also advises nutritional therapists to avoid detoxification claims.
Titles. Do not let your marketing be confused with that of an HCPC-registered dietitian.
Supplements. Section 15 of the CAP Code applies to health and nutrition claims for food supplements. Ads must not state or imply that a balanced or varied diet cannot provide appropriate quantities of nutrients in general, and must not suggest a widespread vitamin or mineral deficiency without well-established proof (rule 15.8).
The CNHC Code points the same way: factual and verifiable information, no unsubstantiated claims, no fear of future ill-health, and respect for the Cancer Act 1939. Since 2023 the PSA has asked CNHC to strengthen its checks on responsible advertising, so registers do look at this.
Ireland: an open title and a strong professional association
The framework. The Department of Health states that people who provide complementary therapies "are not subject to professional statutory regulation", while remaining subject to consumer, competition, contract and criminal law, and that it "supports greater voluntary self-regulation of the sector".
The protected title next door. Dietitians are regulated by CORU. The Dietitians Registration Board, set up under the Health and Social Care Professionals Act 2005, opened its register on 31 October 2014, and the title dietitian/dietician has been protected since 31 October 2016. The Irish Nutrition and Dietetic Institute confirms that the title nutritional therapist is unregulated, and that nutritional therapists are eligible neither for CORU registration nor for the UKVRN.
The body that matters. NTOI, Nutritional Therapists of Ireland, is "the professional association supporting qualified Nutritional Therapists in Ireland" and has more than 300 members. Members study for a minimum of three years at a recognised college, are trained in clinical practice, are fully insured and must meet NTOI's CPD requirements. It also carries a commercial effect: on a schedule published by NTOI, Irish Life Health offers a contribution on selected plans towards a nutritionist "registered with the Nutritional Therapists of Ireland". Check current plan terms with the insurer.
BANT and CNHC from Ireland. BANT's membership terms exempt full practising members who neither live nor practise, physically or virtually, in the UK from CNHC registration. If you see UK clients online from Ireland, CNHC's eligibility criteria accept practitioners whose work with UK-based clients is entirely remote.
Advertising in Ireland. The Food Safety Authority of Ireland explains that Regulation (EC) No 1924/2006 on nutrition and health claims covers food supplements and applies to all commercial communications, advertising included, with authorised claims listed on the EU Register. The Advertising Standards Authority's Code applies to all marketing communications in Ireland, and it offers free copy advice.

What this means for you
Your registration is the answer to "are you registered?", so name it clearly: CNHC and BANT in the UK, NTOI in Ireland, and both if you see clients in both countries. Build your marketing on what CAP accepts (overall health and wellbeing, weight management, a diet suited to an active life) and describe your method rather than promising outcomes for named conditions. Write to the GP, with the client's consent, whenever care overlaps: the CNHC Code treats co-management as normal practice. Be open about how you earn from the supplements you recommend. And keep your CPD log current: CNHC can ask for evidence, and BANT asks you to log your hours.
Key points
- Nutritional therapy is not statutorily regulated in the UK or Ireland; dietitian is the protected title in both, under HCPC and CORU.
- CNHC runs a PSA Accredited Register, first accredited in 2013, at £75 a year for one discipline, with 15 hours of CPD a year.
- BANT full practising membership costs £165 (£145 renewal) and requires CNHC registration, insurance, 30 hours of CPD a year and an NTEC-accredited qualification.
- The CNHC Code sets the scope: no replacement for medical advice, no advice to stop prescribed treatment, referral and co-management with the GP when needed.
- CAP accepts claims about overall health and wellbeing; claims to treat or prevent disease need robust clinical evidence.
- In Ireland, NTOI (300+ members) is the reference body: three years of study, insurance and CPD.
