Function Health in the UK: Can You Get It, and What to Use Instead (2026)

1. Function Health at a glance

Figures checked June 2026 from publicly available US pricing.

2. What Function Health is, and why Americans rate it

Function Health launched in the US in 2023 and grew fast. The pitch is simple and genuinely appealing: one membership, one fee, and more lab data about your body than most people accumulate in a decade of doctor visits. The advertised first year costs $365, renewing at $499, and covers 160-plus lab tests across the year. You get a panel of 100-plus markers up front, then a 60-plus marker retest six months later, so the membership bakes in the thing most people never do voluntarily, which is testing twice.

The draws are venous, done at Quest partner labs across the US. That is a real advantage for panel size. A vial of blood from a vein supports far more tests than a finger-prick card ever can, which is how Function reaches numbers like 100-plus markers in a single sitting.

Members get their results back in an online dashboard, marker by marker, with explanations. And this is where the honest critique lives, even among people who like the service. Function is data-rich and action-light. You finish with an extraordinary picture of your body and a familiar question hanging in the air: now what? The dashboard tells you which numbers are off. Deciding what to actually do about them remains, mostly, your job.

Still, credit where due. Function made annual whole-body testing feel normal to a mainstream audience, priced it below the à la carte cost, and proved people will pay for it. That is why “Function Health UK” is a search worth answering.

3. The Companies House signal

Here is everything that is publicly known about Function's UK plans. Function Health Ltd was incorporated at Companies House on 12 November 2025, company number 16849907. That is it. The whole signal.

No UK website. No waiting list. No pricing, no announced lab partner, no launch date. A Companies House filing costs almost nothing and commits a company to even less, so treat it as a statement of interest rather than a promise. If you are holding off testing until Function arrives, you are waiting on a service whose UK shape, price and panel are all unknown.

4. Why the UK market is different

If and when Function does land here, it will not be entering the market it grew up in. Three things make the UK genuinely different.

The NHS baseline is free. If a blood test is clinically indicated, your GP will run it at no cost. That covers a meaningful chunk of what any private panel measures, things like full blood count, kidney and liver function, HbA1c and lipids when there is a reason to check them. The US has no equivalent, which is part of why a $365 membership reads as a bargain there. In the UK, private testing earns its money on the markers the NHS will not run for a healthy person, and on interpretation.

Lab quality is already standardised. Reputable UK private providers use UKAS-accredited laboratories working to ISO 15189, the same standard NHS labs meet. “Lab-quality testing” is not a differentiator here. It is the entry requirement.

Finger-prick kits dominate. US consumer testing is built around driving to a draw site. UK home testing went the other way: a kit through your letterbox, a finger-prick at your kitchen table, a prepaid return envelope. The trade-off is panel size per sample, which is why UK panels tend to run 20 to 60 markers rather than 100-plus. The benefit is that nobody books anything. A Function-style venous model would be swimming against the habit.

5. What to use in the UK instead

Nothing in the UK is an exact clone of Function. But depending on what attracted you to it, there are good answers here today.

If it was the breadth: Medichecks. Founded in 2014, Medichecks runs the widest test catalogue of any UK home provider, hundreds of individual tests and panels up to 59 markers, with written doctor commentary on every report and a venous-draw option for the biggest panels. It is the closest UK answer to “test everything”. The catch is that the choosing is on you. Our Medichecks vs Thriva guide covers it in depth.

If it was the dashboard and the retesting rhythm: Thriva. Thriva is app-first and built around retesting every three to six months, with results as trend lines rather than documents. Smaller panels, but the repeat cadence is handled for you, which is the part of Function's model most providers skip.

If it was the philosophy, test properly and act on it: this is the gap we built Helvy for. Helvy is neither a catalogue nor a tracker. Five curated panels, £99 to £159, each built around a goal rather than a marker count. A qualified clinician reviews every result. Your report arrives as Your Read, written in plain English against optimal ranges rather than just the wide “normal” bands, and it ends with a plan built from what your blood actually showed. Not a dashboard and a question mark.

The closest thing in spirit to Function's whole-year model is the Helvy Year at £849: an annual membership with your retest included, at UK prices, available now rather than pending a launch nobody has announced. Our comparison of Helvy and Function Health sets the two side by side, and if you want the full market picture first, the private blood test cost guide covers every price band.
