Yes, they’re the same hospital. The Princess Margaret Hospital in Windsor is now part of Circle Health Group, which is why you may see it referred to as Circle Windsor or the Circle Princess Margaret Hospital. It was previously operated by BMI Healthcare, so older references to BMI The Princess Margaret Hospital also mean the same place. The hospital’s official name remains The Princess Margaret Hospital, and it’s located on Osborne Road in Windsor. So whether you’ve been referred to Circle Windsor, BMI Princess Margaret, or simply The Princess Margaret Hospital, it’s one and the same private hospital, just under different ownership over the years. The change in group ownership doesn’t change the location or the core services offered.

As part of Circle Health Group, The Princess Margaret Hospital uses all-inclusive fixed-price packages for self-pay treatment, so the quote you’re given covers the surgeon, anaesthetist, hospital stay and standard aftercare with no hidden extras. There’s no single public price list, as costs depend on the consultant and procedure, but typical private ranges are around £150-250 for an initial consultation, £350-700 for an MRI, £12,000-16,000 for a hip replacement, £2,500-4,000 for a hernia repair, and £1,500-2,500 for a colonoscopy. For an exact figure you request a written fixed-price quote from the hospital. Circle also typically offers finance options to spread the cost of self-pay treatment. Insured patients usually pay little or nothing beyond any policy excess, subject to pre-authorisation.

The Princess Margaret Hospital is on Osborne Road, Windsor, Berkshire, SL4 3SJ, on the edge of Windsor Great Park and within sight of Windsor Castle. It’s about 20 miles west of London and 8 miles from Heathrow airport, and roughly a five-minute taxi ride from both Windsor & Eton Riverside and Windsor Central stations, so it’s easy to reach by car or train. There is free parking on site for patients and visitors, though the car park uses an ANPR (automatic number plate recognition) system, so you’ll need to register your vehicle registration at one of the terminals inside the hospital on arrival to avoid a fixed penalty. The hospital serves Windsor, Maidenhead, Ascot and the wider Berkshire area.

The Princess Margaret Hospital offers a broad range of private treatment across most major specialties. Its strengths include orthopaedics and joint surgery, general surgery, cosmetic and plastic surgery, and cancer care, with developing specialist oncology services including advanced prostate treatments like HIFU and NanoKnife. It has four operating theatres, an endoscopy suite, and on-site diagnostics including MRI, CT, ultrasound and X-ray, so consultation, testing and treatment can happen in one place. Patients are cared for in single en-suite rooms. The hospital treats self-pay patients, those using private medical insurance, and some NHS-funded patients. As with any hospital, the right choice often depends on the consultant you want to see and, if you’re insured, whether it’s on your policy’s hospital list.

Yes, in most cases. As a Circle Health Group hospital, The Princess Margaret Hospital is recognised by the major UK health insurers, including Bupa, AXA Health, Aviva, Vitality and WPA, though whether your specific policy covers it depends on your hospital list tier and cover level. Some lower-cost plans use a restricted hospital list that may or may not include it, so it’s worth checking before you book. You’ll normally need pre-authorisation from your insurer and, usually, a GP referral first, and your treatment may be subject to your outpatient limits and any excess. As it’s the main private hospital in Windsor, it’s a common local choice, so if it’s your preferred hospital it’s worth comparing insurers on both price and whether they include it on your plan.
