Can I mix private and NHS treatment?
Short answer
Yes. NHS and private care must be treated as separate episodes, so you cannot be charged for NHS care you were entitled to simply because you are paying privately alongside it. Going private for a scan or consultation never removes your NHS entitlement.
The governing principle is the separate episode rule. An NHS body cannot charge you for NHS care because you are also buying private care, and it cannot make NHS treatment conditional on accepting private services.
What that means in practice
- Paying for a private room in an NHS hospital does not affect the clinical care — operations, drugs and nursing remain free on the NHS.
- Receiving NHS treatment for one condition and private treatment for another at the same time are separate episodes; neither affects the other.
- Having private health insurance is irrelevant to your NHS entitlement. A trust cannot refuse or deprioritise you because you are insured.
Top-up payments have been permitted since 2009 guidance: you can pay privately for a drug or treatment the NHS does not fund while continuing to receive your NHS care. The private element should be clearly separated and contracted, and the NHS must not reduce its own contribution because you are paying. Implementation varies between trusts, so get a written agreement setting out what is NHS-funded and what you are paying for before anything starts.
Going private first, then returning
Many people buy a private consultation or scan — where NHS waits are longest — and then return to the NHS for treatment. You are entitled to do that. Your private specialist writes to your GP, who makes an NHS referral; an NHS consultant may accept recent private test results to avoid duplication, though they are not obliged to. The 18-week clock runs from the NHS referral, not from your private appointments, which is the main financial risk: you may pay for diagnostics and still wait for treatment.
If a treatment is not routinely commissioned, your consultant can submit an Individual Funding Request to the Integrated Care Board arguing exceptional clinical circumstances, with a right of appeal to an independent panel. Paying privately after a refusal does not prejudice anything — the private episode stays separate. And where NICE has issued a positive technology appraisal, the ICB must fund it for eligible patients within 90 days.
On the insurance side, get pre-authorisation before elective treatment, check network restrictions and exclusions for pre-existing and chronic conditions, and if a claim is refused use the insurer's complaints process and then the Financial Ombudsman Service, which is free.
