Quick Answer
BMI Healthcare was acquired by Circle Health Holdings in a deal completed in January 2020, and its network of hospitals was rebranded as Circle Health Group from 2022. The “BMI Healthcare” name has now been fully retired. The combined group is the UK’s largest private hospital provider. In August 2023, Circle Health Group was itself acquired by PureHealth, an Abu Dhabi-based healthcare company — so PureHealth is the current ultimate owner.
If you’re looking for a “BMI hospital,” you’re now looking for a Circle Health Group hospital — the facilities, consultants and services largely continued, just under a new name. This guide explains exactly what happened and how to be seen.
What this guide covers
If you remember “BMI Healthcare” and are trying to work out what happened to it, you’re in the right place — and you’re not alone, as it’s one of the most common questions about UK private hospitals. Going Private UK is editorially independent and not affiliated with Circle Health Group, BMI or PureHealth; we may earn commission when readers compare cover through our links, which funds our research but doesn’t affect our analysis.
What happened to BMI Healthcare?
BMI Healthcare was, for decades, one of the UK’s largest independent private hospital operators, running around 50–59 hospitals and clinics nationwide. In December 2019 a deal was announced for Circle Health to acquire BMI’s parent company (GHG Healthcare Holdings), and the acquisition completed on 8 January 2020.
The two businesses merged to become the UK’s biggest private hospital group. From 2022, the former BMI hospitals were rebranded under the Circle Health Group name, and the BMI brand was gradually retired. Today, “BMI Healthcare” no longer operates as a trading name — every former BMI hospital is now a Circle Health Group hospital.
In one line
BMI Healthcare → acquired by Circle (Jan 2020) → rebranded Circle Health Group (from 2022) → acquired by PureHealth (Aug 2023). Same hospitals, new owner and name.
Who owns BMI Healthcare (Circle Health Group) now?
This is where it gets a step further than many people realise. After Circle acquired BMI, Circle Health Group itself was acquired in August 2023 by PureHealth — the largest healthcare provider in the United Arab Emirates — in a deal reported at around $1.2 billion. So the ownership chain today is:
- Former BMI hospital → operated by Circle Health Group
- Circle Health Group → owned by PureHealth (Abu Dhabi, since 2023)
Circle Health Group remains UK-run and UK-based, with over 50 hospitals and thousands of staff. In 2025 it was named one of the NHS’s strategic suppliers, reflecting how integrated private capacity has become with NHS waiting-list initiatives.

💡 A note on the “BMI hospital” you remember
If you were treated at, or referred to, a “BMI hospital,” it’s now a Circle Health Group hospital at the same location with largely the same consultants and services — just a different name. A couple of sites changed hands for competition reasons (the former Circle Bath hospital was divested), so if in doubt, check the current operator before booking.
What services do former BMI (Circle) hospitals offer?
As the UK’s largest private hospital group, the network offers full-service private care:
- Private consultations with GPs and specialists
- Diagnostics — MRI, CT, ultrasound, X-ray and blood tests
- Elective surgery — orthopaedics, cardiology, ENT, general surgery and more
- Health screening and executive check-ups
- Physiotherapy and rehabilitation
- Private maternity care at selected locations
Like other major groups such as Ramsay, Spire and Nuffield, they offer same-week appointments, consultant choice and private rooms. Compare the main groups in our top UK providers guide or browse the private hospitals hub.
Insurance & how to be seen
Former BMI (now Circle) hospitals are recognised by all the major UK insurers — including Bupa, AXA, Aviva, Vitality and WPA — though your access depends on your policy and hospital list. You can be seen three ways:
- Through insurance — confirm the hospital is on your plan’s list and get pre-authorisation. See the Bupa and AXA hospital lists.
- Via a private referral — ask your GP; see how to get a private referral.
- Self-pay — book directly; some services (e.g. screening, physio) need no referral. Check whether you’ll pay upfront and see typical costs in our price list.
Insurers cover eligible consultations, diagnostics and inpatient procedures (minus any excess), subject to your policy terms.
Former BMI (Circle) vs the NHS
The NHS provides free care but waiting lists for diagnostics and elective surgery can be long. A private hospital offers faster access (often same-week appointments), choice of consultant, private rooms, and the ability to skip queues for scans and procedures — which is why people turn to them for time-sensitive issues. It’s not a replacement for NHS emergency care: private hospitals don’t run A&E departments.
The bottom line
BMI Healthcare became Circle Health Group after Circle’s January 2020 acquisition and the rebrand from 2022 — and Circle Health Group has been owned by PureHealth (Abu Dhabi) since 2023. The “BMI” name is gone, but the hospitals, consultants and services continue under Circle.
If you want fast access to a former BMI (now Circle) hospital without the upfront bills, the right health insurance can cover consultations, diagnostics and surgery. Compare the UK’s top providers free here — and skip the NHS waiting list.
