Private firms providing services to the NHS made £1.6 billion in profit over the last two years, according to new research.
Analysis of £12 billion in contracts suggests that this taxpayer money, enough to fund 19,428 nurses, is being diverted from frontline patient care.
Is private sector profit-making in the NHS legal?
Yes, it is entirely legal. The NHS has long used independent providers to fill gaps in care, particularly for elective surgeries like hip replacements or diagnostic tests. However, the sheer scale of the “leakage” has sparked a political firestorm.
Critics argue that while the independent sector is meant to help clear backlogs, the current system allows for “super-profits.” The Centre for Health and the Public Interest (CHPI) found that 28 specific firms are hitting profit margins of at least 17%.
For many observers, this isn’t just a business transaction; it’s a moral issue. If the government can cap profits for firms providing children’s social care at 8%, many are asking why the same logic isn’t applied to healthcare, especially as the NHS trusts’ deficit continues to climb.
Which companies are winning these NHS contracts?
The list is broader than you might think. It isn’t just private hospitals like Spire or Circle Health Group. The £12 billion spend covers a massive web of 760 firms. This includes:
- Diagnostic specialists: Companies like InHealth that run mobile CT and MRI scanners.
- Management consultants: Giants like PwC and PA Consulting.
- IT and Tech: Firms managing electronic patient records and digital infrastructure. Many of these contracts are now falling under the new Buy British tech policy aimed at boosting domestic AI.
- Specialist clinics: Private ventures handling everything from cataract surgery to mental health support.
Where is the NHS contract money actually going?
One of the most stinging parts of the CHPI research involves where the cash ends up. The reality is that a significant chunk of British taxpayer money isn’t staying in the UK economy.
| Category of Spending | Financial Impact |
| Total Profit (2023-2025) | £1.6 Billion |
| Contracts with Overseas Owners | £2 Billion |
| Cash sent to Tax Havens | £533 Million |
| Debt Interest Payments | £353 Million |
| Equivalent Cost in Nurses | 19,428 staff |
| Equivalent Cost in Doctors | 9,178 staff |
Why This Matters?
We found that the debate around “privatisation” often misses the plumbing of the system. It’s easy to focus on the logo on the hospital door, but our analysis suggests the real issue is the lack of transparency in how these contracts are structured.
The fact that over half a billion pounds flowed to companies linked to tax havens like Jersey and the Cayman Islands is a bitter pill for a public facing record waiting lists.
But here’s the kicker: even as the NHS struggles with its own crumbling infrastructure, private equity-owned firms are using NHS income to service their own corporate debts.
Anyway, for most people, the priority is getting seen by a doctor. But if the government doesn’t get a grip on these margins, we are essentially subsidising private dividends with money meant for the ward.
We believe a profit cap isn’t just a radical idea; it’s becoming a financial necessity to keep the “free at the point of use” promise alive.
