Booking your first weight-loss clinic consultation online can feel oddly abstract. There is no waiting room, no receptionist, no white coat across the desk — just a form on your phone and a promise that a real prescriber is on the other side. So what actually happens between clicking "start" and a KwikPen arriving at your door?
This guide walks through a typical online weight loss clinic consultation step by step: what you will be asked, why each check exists, and how long it takes. The details vary between clinics, but the shape is consistent — because it is built around the duty every UK provider shares: a prescriber, not a shopping basket, decides whether treatment is right for you.
The short version
An online consultation is a structured health questionnaire, an identity and photo check, and a clinical review by a GPhC- or CQC-registered prescriber. It is designed to screen you out if a GLP-1 medicine isn't safe or suitable — which is exactly why "guaranteed approval" is a red flag, not a feature.
Step 1: The health questionnaire
Everything starts with a form. A good clinic's questionnaire is longer than you might expect, and that is a good sign — it means the prescriber is being given enough to make a safe decision rather than rubber-stamping an order.
Expect to be asked about:
- Your height and weight, so the clinic can calculate your BMI. NICE guidance (TA1026 for tirzepatide) generally frames treatment around a BMI of 30 or more, or 27 and above where you also have a weight-related condition such as high blood pressure or type 2 diabetes.
- Your medical history — thyroid conditions, pancreatitis, gallbladder problems, diabetes, eating disorders, and a family history of certain thyroid cancers, all of which can affect whether a GLP-1 medicine is appropriate.
- Current medications, so the prescriber can check for interactions.
- Pregnancy and breastfeeding status, since these medicines are not used in pregnancy.
- Past weight-loss attempts and, at some clinics, your goals and lifestyle.
Be honest here, even about the awkward bits. The questionnaire isn't a test you pass by giving the "right" answers — it is the safety net. Leaving something out to improve your chances defeats the point of having a prescriber involved.
Step 2: ID and photo verification
Because these are prescription-only medicines, the clinic has to be confident you are who you say you are — and, increasingly, that your BMI figures are genuine. That usually means:
- Uploading a photo of government ID (passport or driving licence).
- A selfie or short video to match against the ID.
- At some clinics, a photo of you that helps corroborate your stated weight, or a request to weigh yourself on camera.
Clinics that skip identity and weight verification entirely are cutting a corner that exists to protect patients. It is one of the checks we look at closely in our weight-loss clinic red flags guide.
Step 3: The prescriber review
This is the part that happens out of sight, and it is the most important. Once you have submitted everything, a registered prescriber — a pharmacist independent prescriber or a doctor — reviews your answers against clinical criteria.
One of three things then happens:
- Approved. Your prescription is issued and the pharmacy prepares your order.
- More information needed. The prescriber sends follow-up questions, asks for a clearer photo, or requests a GP letter before deciding.
- Declined. A GLP-1 medicine isn't suitable or safe for you right now. This is not the clinic being difficult — it is the system working.
A decline can be frustrating if you have already paid, which is why refund policy matters so much. Our recommended clinic, The Weight Clinic, offers a free consultation and refunds you if you are declined, so the consultation carries no financial risk. Not every clinic does this — it is always worth checking before you pay.
Prefer a consultation with a safety net?
The Weight Clinic is our recommended provider: a free consultation, a refund if you are declined, and monthly video reviews with the clinical team once you start. New patients can use code NEWME for £35 off a first order.
Step 4: What "the consultation" actually includes — and how clinics differ
Here is where the word "consultation" starts to mean different things. At one clinic it is a free questionnaire you only pay for if prescribed. At another it is bundled into a subscription. At a third it comes with an ongoing coaching app and scheduled video reviews. Same legal process, very different experience — and very different aftercare.
The table below compares the consultation and review model at a handful of UK clinics, using each clinic's own published service details and their price for the Mounjaro 2.5 mg starter dose. Prices were last checked on 24 August 2026.

Prices last checked 01 September 2026. Figures are the starter-dose price for the first month; ongoing prices differ. All listed clinics are GPhC- and/or CQC-regulated. This is price and service information, not an offer of supply — confirm current prices and terms on each clinic's own site.
Notice that a "free consultation" tells you little on its own — nearly everyone offers one. What separates clinics is what happens after approval: whether there is a human check-in, how dose increases are handled, and whether you can reach a clinician when side effects hit. We dig into that in how clinic support compares.
Step 5: After you're approved
Once a prescription is issued, the pharmacy dispenses your medicine and arranges delivery — usually tracked and, for these temperature-sensitive injections, in cold-chain packaging. Many clinics include needles; check, because a few don't.
The consultation doesn't really end at delivery, though. GLP-1 treatment is a dose ladder: tirzepatide starts at 2.5 mg weekly for four weeks — a starter dose, not a treatment dose — before stepping up. Each increase should involve a fresh check on how you are tolerating it. At clinics with monthly reviews that check is built in; at others you request the next dose yourself.
How long does it all take?
The questionnaire takes most people ten to fifteen minutes; identity checks add a few more. The prescriber review can be same-day, or a day or two where every case is read carefully — slower is not worse. Delivery is often next-day after approval. From starting the form to holding a pen, expect anywhere from a day to most of a week.
Frequently asked questions
Do I speak to a doctor on a video call?
Not usually for the initial consultation — most UK online clinics run it as a written questionnaire reviewed by a prescriber, with follow-up messages if anything is unclear. Some clinics, including The Weight Clinic, add scheduled video reviews once you have started treatment, which is where a face-to-face check adds the most value.
Can I be turned down after paying?
Yes. A prescriber can decline if a GLP-1 medicine isn't safe or suitable for you. This is why refund-if-declined policies matter — at clinics that offer one, being declined costs you nothing. Always check the refund terms before you pay.
What if I don't have a recent weight or BMI?
You will be asked to weigh yourself and provide your height so the clinic can calculate your BMI. Some clinics ask for a photo or an on-camera weigh-in to verify it. Being accurate protects you — the criteria exist for clinical reasons, not as hurdles to game.
Is the consultation really free?
At most clinics the consultation itself is free and you only pay if a prescription is issued. The differences are in what the price then includes — subscription versus one-off, coaching, delivery and needles — so compare the whole package, not just the headline "free consult".
Which clinic has the best consultation experience?
It depends on what you want from aftercare. If you value a human check-in and a no-risk start, our recommended pick is The Weight Clinic.
