For most private screening you can self-refer and book directly, without a GP referral — this is true for many mammograms, PSA blood tests, FIT stool tests and full-body scans. Some advanced imaging or invasive tests, such as a colonoscopy or certain MRI pathways, may still need a GP or specialist referral, and a referral is always sensible if you have symptoms. If you do have symptoms rather than just wanting a screening check, see your GP first, as symptoms need proper diagnostic assessment, not routine screening.

Usually not. Most UK health insurance is designed to diagnose and treat new medical conditions, not to fund routine screening or preventative checks when you have no symptoms — so a screening mammogram or PSA test you arrange yourself is normally self-pay. The important exception is what happens next: if screening finds something, or you have symptoms, your policy may cover the onward diagnostics, specialist consultations and treatment (subject to your terms and any pre-existing exclusions). Some plans include a health-assessment benefit, so check your policy wording.

It depends on the test. As a rough 2026 guide: a private mammogram is around £150 to £300, a PSA blood test £50 to £120, a prostate mpMRI roughly £350 to £900, a FIT stool test £50 to £100, a colonoscopy about £1,000 to £2,500, a skin/mole check £100 to £250 (biopsy extra), and a full-body screening scan £500 to £2,000 or more depending on scope. Prices vary by clinic and location, and follow-up tests add cost, so always ask for a clear, itemised quote first.

Not usually — the tests themselves are generally the same ones the NHS uses, so the accuracy of the individual test is comparable. The main advantages of going private are speed, flexible appointments, and broader eligibility, since you can be screened outside NHS age bands or invitation intervals. It’s worth knowing that screening isn’t perfect: it can produce false alarms, miss some cancers, or find harmless things that lead to more tests (overdiagnosis). A normal result also doesn’t remove future risk.

Screening has real benefits but also trade-offs worth understanding. Tests like PSA are non-specific, so raised results can come from non-cancer causes and trigger further tests and anxiety. Full-body scans often find incidental abnormalities that turn out to be harmless but still need investigating. There’s a risk of overdiagnosis — detecting slow-growing cancers that would never have caused harm — and a normal result can create false reassurance. This is why screening is best chosen thoughtfully, ideally with clinical advice about what’s appropriate for your age and risk.

It’s most worth considering if you fall outside NHS screening eligibility but have reason for concern — for example a strong family history of a particular cancer, known risk factors, or wanting checks earlier or more often than the NHS offers. It can also suit people who simply want faster access and reassurance. If you have actual symptoms, though, you need diagnostic assessment, not routine screening — see your GP promptly. Deciding what to screen for, and how often, is best done with clinical guidance rather than screening for everything by default.

If a screening test flags a possible concern, you’ll usually be referred for further diagnostic tests — such as an ultrasound, biopsy or specialist consultation — to confirm what it is. At this point, if you have private medical insurance, your policy may cover these onward diagnostics and any treatment, because you now have a clinical indication rather than routine screening. You can also continue on the NHS. Either way, a positive or uncertain screening result is a starting point for proper assessment, not a diagnosis in itself.
