Who leads the care?
Check the clinician's role and registration, who interprets tests, and who is responsible for diagnosis, prescriptions, referrals and follow-up.
Independent provider comparison
Compare functional medicine clinics in London
Compare London functional medicine doctors and clinics by the care model they record, the services they publish, how pricing is structured and the route into an appointment.
Functional medicine and integrative medicine are broad labels, not one standard appointment or package. MHI includes a provider here only when its record has London coverage, an explicit functional-medicine service and an indexable profile. A broader wellness or integrative-health description alone is not enough.
Compare the care, not just the label
Questions to ask a functional medicine provider
A longer consultation, a larger test panel or a higher package price does not by itself show that a service is more suitable. Compare the proposed process and what happens after the results.
What does the first price include?
Separate an introductory call or consultation fee from laboratory testing, treatment, programme charges and later appointments.
Which tests are optional?
Ask why each test is being proposed, how it could change care, whether a conventional route is available and what interpretation costs.
How does follow-up work?
Confirm the expected timeline, whether results can be shared with your GP, and what happens if a test identifies something needing specialist care.
Provider comparison
Compare 3 London functional medicine providers
Compare the recorded service model, London coverage, relevant services, published pricing and booking route. Some providers centre on a functional-medicine consultation, while others place it within a broader longevity or hormone-care offer.
Providers are alphabetical. MHI does not rank providers by payment, sponsorship or an arbitrary score. Inclusion is not a medical recommendation, and services, prices and availability should be confirmed directly.

Use a practical framework for checking clinical scope, oversight, pricing and follow-up before booking.
Private GP consultation
Understand the primary-care route and why it is not interchangeable with every functional-medicine service.
Private health screening

Questions about functional medicine in London
How much does functional medicine cost in London?
There is no single comparable fee. The current MHI records include introductory calls, consultation fees, follow-ups, laboratory estimates and broader programme starting prices. Check what testing, interpretation and follow-up are included before comparing the headline amounts.
Is functional medicine the same as integrative medicine?
The labels overlap in commercial use, but providers define their scope differently. This page does not treat every integrative, holistic or wellness service as equivalent. Inclusion requires a directly recorded functional-medicine service and London coverage.
Is a functional medicine doctor the same as a private GP?
Not necessarily. The appointment scope, clinician, testing, prescribing and follow-up can differ. Check the individual clinician's role and registration and whether the service can provide primary care, coordinate with your GP or refer into an appropriate specialist pathway.
Does MHI recommend a best functional medicine clinic?
No. Providers are shown alphabetically using supported comparison fields. MHI does not assign a universal winner or make a medical recommendation.
