Private weight management in London

The short answer

What is private weight management?

Private weight management is a clinical service that assesses why your weight is where it is and manages that, rather than the number on the scales. A thorough first assessment takes 45 to 60 minutes, covers your history, measurements and bloods, and ends with a written plan, a named contact and a review date.

Who is private weight management for?

Private weight management is for adults who want a clinician to look at why their weight is where it is, with the answer written down and reviewed. It is not for anyone under 18, pregnant or breastfeeding, or already in the healthy range; when weight loss is not the right goal is covered further down this page, and am I overweight? sets out the BMI and waist checks.

  • You have lost weight before and it came back

    The assessment looks at what happened when earlier plans stopped working, so the next one is not the same plan again.

  • Your weight has changed for no clear reason

    Thyroid function, blood sugar and your other medicines are checked before anybody assumes the answer is willpower.

  • You want a registered clinician to check it

    A registered practitioner carries a professional duty to you personally and can order blood tests a diet programme cannot.

  • You want it discreet and near work

    Assessments are at 1 Orchard Street, W1H, on the north side of Oxford Street, and nothing reaches your GP without your agreement.

What can a weight management assessment help with?

An assessment looks for what is driving your weight before anybody writes a plan. These are the questions people most often bring to one.

  • Checking whether you are overweight
  • Weight loss that has stalled
  • Weight gain you cannot explain
  • Weight gain with an underactive thyroid
  • Weight gain in perimenopause and menopause
  • Insulin resistance and prediabetes
  • Visceral fat and a growing waist
  • Fatty liver found on a blood test or scan
  • Stress, sleep and weight gain
  • Keeping weight off after losing it

What a first weight management assessment includes

Expect 45 to 60 minutes. A short first appointment is the clearest early signal that the plan was decided before you arrived.

Your weight history

The practitioner should go back years rather than months: what you have tried, what worked for a while, and what happened when it stopped working.

Measurements

Height, weight, waist and blood pressure. NICE recommends measuring waist-to-height ratio alongside BMI for adults with a BMI under 35, because it says more about the fat that carries health risk.

Blood tests

A standard panel covers thyroid function, HbA1c (blood sugar over the previous two to three months), liver and kidney function, and cholesterol. It looks for anything treatable and gives you a line to measure against later.

A written plan

You should leave with a written plan, a named contact and a review date.

Ask What Happens First

What a weight loss clinic actually does

A weight management clinic assesses why your weight is where it is, then treats that rather than treating the number. In practice it means a long first appointment, a set of baseline measurements, a look at your history and a plan you review at intervals. The useful ones are unglamorous and they take a while.

The word clinic covers a wide range. At one end sits a service staffed by doctors and dietitians with proper review appointments. At the other sits a room where the assessment is a form. Both are entitled to call themselves a clinic, and the fee frequently does not tell you which you are in. What separates them is what happens in the first hour.

What medical weight management means

Medical weight management treats weight as a clinical problem with a clinical process behind it. It rests on NICE guideline NG246, which sets out how adults with overweight and obesity should be assessed and managed in the UK, and a good private service follows it closely.

The practical difference from a commercial diet programme is accountability. A registered clinician carries a professional duty to you, answers to a regulator, and can be complained about to someone other than the company that took your money. It also means the assessment can order bloods and check what you already take. A service that cannot order a blood test is not doing medical weight management, whatever it says on the door.

Why am I not losing weight?

The most common reason a sustained effort produces nothing is that something else is going on, and the second is that the effort was never sustainable. A proper assessment separates the two before it recommends anything, because the answers are completely different.

An underactive thyroid

The NHS lists weight gain and tiredness among the common symptoms of an underactive thyroid, and says they usually develop slowly. It is common, it is a routine blood test, and it is treated by your GP. It is worth excluding before any plan is written, because a plan built on an untreated thyroid is built on the wrong information.

Insulin resistance and prediabetes

Prediabetes means blood sugar that is higher than it should be, which Diabetes UK defines as an HbA1c of 42 to 47 mmol/mol. It usually causes no symptoms, so it is found on a blood test rather than noticed. It changes how a plan should be built, and it is one of the reasons HbA1c belongs in a first assessment.

Sleep and stress

Poor sleep and sustained stress both change appetite in ways that are well documented and frequently mistaken for a lack of willpower. An assessment asks about both, because a plan that ignores a four-hour night is unlikely to hold. Cortisol belly and stress weight gain covers what the NHS says about it.

Medicines for other conditions

Several widely prescribed medicines for unrelated conditions can make weight harder to shift. Bring a full list to the assessment, including supplements, and never stop a prescribed medicine without talking to whoever prescribed it.

Ask What Happens First

Weight loss plateau: why it happens and what changes it

Almost everyone stalls, and the stall is not a failure of effort. As weight falls the body needs less energy to run, appetite shifts upward, and the gap you originally created closes on its own. The plateau is the system working, which is cold comfort but useful to know.

The set point idea describes the same thing from the other end: the body defends a range rather than a number. That is why a plan that only works while you are actively restricting tends to unwind, and why the maintenance conversation belongs at the beginning. What changes a plateau is usually a review of the whole plan, including protein, strength work and sleep, rather than cutting further. A clinic worth paying should tell you a plateau is coming before it arrives.

Weight gain in perimenopause and menopause

The NHS describes weight gain during perimenopause and menopause as common, and notes that it often settles around the stomach and upper body. That shift in where weight sits is part of why a waist measurement matters more in midlife than the number on the scales.

An assessment is useful here for two reasons. It rules out the things that look similar, such as an underactive thyroid, which is also common in the same years. And it builds a plan around what changes in midlife: muscle is harder to keep, sleep is often worse, and a plan that relies on restriction alone tends to cost muscle first. Questions about menopause symptoms themselves belong with your GP or a menopause specialist.

Visceral fat, waist size and your liver

Visceral fat sits around the organs rather than under the skin, and a waist measurement is the simplest way to track it. NICE advises keeping your waist to less than half your height, and treats a waist-to-height ratio of 0.5 to 0.59 as increased central adiposity with increased health risks. The NHS waist-to-height calculator takes a minute.

Fatty liver is often the same story seen in a blood test. The NHS says non-alcoholic fatty liver disease does not usually cause symptoms and is usually found on blood tests or scans done for another reason, and its advice includes losing weight if you are overweight. Liver function is part of the standard panel at a first assessment for that reason.

Keeping weight off after losing it

Losing weight and keeping it off are different problems, and the second is much the harder. Repeated cycles of loss and regain are common enough to have their own clinical term, weight cycling, and the pattern carries costs of its own beyond the discouragement.

Maintenance is an active phase rather than the absence of one. It usually means continued review, a plan for the situations that historically undid you, and an agreed floor you do not go below. Ask at the first appointment what happens at the end, how long maintenance is supported for and what it costs. That answer tells you more about a clinic than anything on its website.

When weight loss is not the right goal

Some people who arrive at a page like this do not need to lose weight, and a service paid to provide weight loss is poorly placed to say so. So this page will. If your weight already sits within the healthy range, further loss carries real risk and no health benefit.

Orthorexia and the signs of disordered eating are looked up far more often than this industry writes about them. If eating has become a set of rules that is difficult to break, if a missed plan produces guilt out of proportion to it, if food decisions take up a lot of the day, or if weight loss has stopped being something you chose, that is worth talking to somebody about before it is worth paying anybody.

Beat is the UK eating disorder charity. Its England helpline is free on 0808 801 0677, 15:00 to 20:00 on weekdays, with online support at beateatingdisorders.org.uk. Your GP can refer you into NHS eating disorder services. Both are better first calls than a weight management clinic.

People carrying extra weight are routinely treated badly by health services, and the experience teaches many not to raise it at all. That is the failure of the service, not of the person in front of it. A clinic where you feel judged in the first appointment is not one that will still have you in six months.

NHS weight management or private?

The NHS runs weight management in four tiers, and knowing where you sit is worth doing before you pay for anything. Tier 1 is self-help, including the free 12-week NHS Weight Loss Plan app. Tier 2 is a structured programme: the NHS Digital Weight Management Programme is a free 12-week online programme for adults with a BMI of 30 or more (27.5 for people from Black, Asian and minority ethnic backgrounds) who also have diabetes, high blood pressure or both, reached through your GP practice or a pharmacist.

Tier 3 is specialist, multidisciplinary care. For people in Kensington and Chelsea and some parts of Westminster registered with a West London GP, it runs at Chelsea and Westminster Hospital, by GP referral. Tier 4 is surgical. Waits can be long, which is an honest reason people go private, and private is a better choice when you know what you are choosing instead of.

Ask What Happens First

What confidentiality in a private clinic covers

A private clinic holds your records separately from the NHS and does not write to your GP unless you agree. For many people that separation is the reason for going private, and it is a legitimate one.

It stops in three places. A clinician who believes you or somebody else is at serious risk of harm can break confidentiality and is expected to. A court can order disclosure. And if you claim on insurance, the insurer sees enough to assess the claim. There is also a cost to the separation: if your GP does not know what you are being treated for, they prescribe and refer with a gap in the record. Telling them is usually the safer choice, and it remains yours to make.

How much does private weight management cost in London?

Enquiring through Weight Loss Clinics Mayfair costs nothing, and as a guide a first private GP appointment in central London is published at £75 to £120. The site sets no fees of its own: the practitioner confirms theirs before anything is booked. These are prices London providers published on their own websites, checked on 30 September 2026.

  • A private GP appointment of about 15 minutes: £75 to £120 in central London clinics.
  • A first appointment with an HCPC-registered dietitian: £149 to £499 at central London practices, usually 60 minutes.
  • A thyroid function blood test: about £45 to £95, before any clinic fee for taking the blood.

A first weight management assessment combines several of these, so the useful questions are what the fee includes. Ask whether it is per appointment or per programme, whether bloods are included, how many reviews are covered, what a further review costs, and what happens if you stop partway. The prices page lists every published figure with its source.

How to choose a weight loss clinic in London

Start with who will actually see you and what they are registered as. A doctor, a dietitian or a registered nurse each holds a professional registration you can check yourself on a public register in about a minute; for dietitians it is the HCPC register. Dietitian is a protected title in UK law and nutritionist is not, which is the single most useful thing to know when two brochures read identically.

Be wary of a package sold before an assessment. If the plan and the price are fixed at the enquiry stage, the assessment cannot change anything. Be equally wary of a fee far below the rest of London: assessment time and clinician seniority are most of the cost, and they are what gets removed to reach a low number.

One thing this site will not help you compare. It publishes nothing about prescription treatments of any kind, because UK law does not permit them to be advertised to the public. Whether anything of that sort is appropriate for you is a clinical question, decided in private by a registered prescriber who has assessed you.

How Weight Loss Clinics Mayfair works

Weight Loss Clinics Mayfair is owned by the UNTIL group and treats nobody itself. It answers the questions properly and then, if you want it, UNTIL Health Concierge arranges an assessment with a registered practitioner. There is no per-enquiry payment behind that introduction, which is a deliberate decision: paying a clinician per patient introduced creates a referral-fee problem under professional guidance and quietly changes whose interest the introduction serves.

The terms used on this page are defined in the weight management glossary, who owns and runs this site is set out on its own page, and the contact page has the address, the hours and the map.

Private weight management questions,
answered

How much does private weight management cost in London?

Weight Loss Clinics Mayfair sets no fees, and the practitioner confirms theirs before anything is booked. As a guide, London providers publish about £75 to £120 for a 15-minute private GP appointment and £149 to £499 for a first appointment with an HCPC-registered dietitian, checked on 30 September 2026.

What happens at a first weight management assessment?

Usually 45 to 60 minutes covering your weight history, what you have already tried, height, weight, waist, blood pressure and a blood panel. You should leave with a written plan, a named contact and a review date. Leaving with only a payment schedule means you bought a product rather than a clinical service.

Which blood tests does a weight assessment include?

A standard panel covers thyroid function, HbA1c (blood sugar over the previous two to three months), liver and kidney function, and cholesterol. If you have had bloods in the last year, ask your GP surgery for a copy before an assessment arranged through Weight Loss Clinics Mayfair, since it can save repeating them.

Which measurements are worth taking at the start?

Weight and waist together, plus blood pressure. Waist is the one people skip and the one that moves when visceral fat comes down. Weight alone mixes fat, fluid and muscle, so a month where the scale holds still while the waist drops two centimetres is a good month misread as a bad one.

Can an underactive thyroid stop you losing weight?

It can make weight harder to shift, and the NHS lists weight gain and tiredness among its common symptoms. It is a routine blood test and is treated by your GP. A first assessment arranged through Weight Loss Clinics Mayfair checks thyroid function before any plan is written, so the plan is not built on an untreated thyroid.

How often should I be reviewed?

Monthly at the start, then further apart as things settle, with the programme running six to twelve months rather than six to twelve weeks. Ask who conducts the reviews, because a plan written by a clinician and reviewed by an administrator is a different service from the one you were quoted for.

Should I try the NHS before going private?

It is worth knowing what you are choosing instead of. The NHS Digital Weight Management Programme is free for 12 weeks if your BMI is 30 or more (27.5 for some ethnic backgrounds) and you have diabetes, high blood pressure or both. Specialist tier 3 care needs a GP referral, and waits can be long.

Is a dietitian the same as a nutritionist?

No. Dietitian is a protected title in UK law, and anyone using it must be registered with the HCPC, which takes about two minutes to check online. Nutritionist is not protected, so it covers somebody with a masters degree and somebody with a short online certificate equally. Ask which register they are on.

How do I know a clinician is properly qualified?

Ask what their professional registration is, then check it yourself on the public register before you book: the GMC for doctors, the HCPC for dietitians, the NMC for nurses. Weight Loss Clinics Mayfair only arranges assessments with registered practitioners, and the same check is worth making wherever you go.

What happens after an enquiry to Weight Loss Clinics Mayfair?

It reaches UNTIL Health Concierge, who reply within 1 hour to book an assessment at UNTIL Marylebone for today or tomorrow. Weight Loss Clinics Mayfair takes no booking, no payment and no fee for the introduction, and it prescribes nothing.
