Consultation Fees: What the Assessment Costs
Every private weight loss injection in the UK requires a clinical assessment by a registered prescriber. It cannot be skipped. What varies is whether you are billed for it separately, bundled into the medicine price, or charged again each time your dose changes.
Mounjaro and Wegovy are prescription-only medicines. A pharmacy cannot lawfully supply either without a prescriber first assessing whether the treatment is appropriate for you, and that assessment has to be genuine rather than a formality. The cost of doing it properly is real, and every provider recovers it somewhere.
Most UK online pharmacies fold the consultation into the price of the medicine and advertise it as free. A minority itemise it, typically at £20 to £50 for an initial assessment. Neither approach is better on its own — a bundled consultation is not free, it is simply priced into the pen. What matters is that you can see the total before you commit, and that you know whether further charges follow.
A free consultation is not a lesser consultation.
Providers that do not charge separately are still bound by the same professional standards. The prescriber remains accountable to their regulator, and the pharmacy to the General Pharmaceutical Council, regardless of how the fee is presented. Do not read a £0 consultation as a sign of a lighter check — and equally, do not read a £40 fee as a guarantee of a thorough one.
Bundled
The consultation is included in the medicine price. Easiest to compare, because one number covers everything clinical. The most common model in the UK.
Itemised
A separate line for the assessment, commonly £20 to £50. Transparent, but it means the advertised medicine price is not the price you pay.
Recurring
A review fee charged again at each dose change or on a fixed schedule. Easy to miss at sign-up, because it does not appear on your first invoice.
The four charges to look for
Clinical charges appear under several names. The ranges below reflect what UK online providers commonly list; many charge nothing under some of these headings.
| Charge | Typical range | When it applies |
|---|---|---|
| Initial consultation | £0 – £50 | Once, before your first supply |
| Prescription writing fee | £0 – £25 | Per order, including repeats |
| Dose change review | £0 – £25 | Each time your strength increases |
| Periodic clinical review | £0 – £30 | Every few months, or annually |
The recurring charges matter more than the one-off. A single £40 initial consultation is a rounding error across a year of treatment. A £15 prescription fee on every order is £180 a year, and a £25 review fee at each of four titration steps is another £100 in your first year alone.
The real warning sign is the absence of an assessment, not the presence of a fee.
If a site will sell you a prescription medicine after a handful of tick boxes, with no meaningful questions about your medical history, current medicines or weight history, and no way for a prescriber to query your answers, that is not a bargain. It is a supply route operating below the standard the GPhC expects. Walk away regardless of the price.
What to ask before you register
- Is the consultation included in the medicine price, or billed separately?
- Is there a prescription fee on every order, or only the first?
- Is a review charged when your dose increases? How many increases should you expect?
- If the prescriber declines to supply, is the consultation fee refunded?
- Can you contact a pharmacist or prescriber between orders without paying again?
- Is the pharmacy’s GPhC registration number displayed, and does the register entry match?
The refund question is worth asking directly. Being told a treatment is not suitable for you is a legitimate clinical outcome, not a failed transaction, and policies on that differ between providers.
