Private colonoscopy cost in the UK: 2026 price guide

A private colonoscopy examines the lining of the large bowel with a flexible camera, and is used for rectal bleeding, a change in bowel habit, anaemia, a family history of bowel cancer or follow-up of earlier polyps.

The range in the published self-pay lists for colonoscopy was £1,564 to £3,635. That spread reflects different hospitals, different variants and different ideas of what belongs in a package, so the table names each one.

Lists are revised from time to time and sit alongside conditions in the small print. The figures help you see where a quote falls, but they cannot replace your own estimate.

The day before, you follow a low-fibre diet and take a strong laxative preparation that empties the bowel, which is often the hardest part. During the test you lie on your side, sedated if you choose, while the camera is passed round the whole colon and any polyps are removed.

If polyps are removed, the pathology result takes days and may change your future surveillance schedule. Ask whether follow-up advice is included in the price.

Two patients having the same operation or test can receive quite different bills. For colonoscopy, these are the factors that most often explain the gap.

• Whether polyps are removed: a colonoscopy with removal of tissue is listed above a diagnostic one, for example £3,601 against £2,809 at Ramsay Berkshire Independent.

• Sedation and setting: ambulatory versus day-patient listings differ, and sedation needs monitoring and recovery space.

• Hospital: published colonoscopy prices ranged from £1,564 to £3,635 across the lists we retrieved.

• Pathology: polyps and biopsies go to the laboratory, and reports can be charged separately.

• Consultant and anaesthetist fees may sit outside a hospital price.

Ask for the inclusions in writing. For this procedure the usual split between what is covered and what is charged on top looks like this.

Insurers usually cover colonoscopy on referral for symptoms, and may not cover screening without symptoms. Confirm whether polyp removal and pathology are within the authorisation.

Check whether your insurer recognises the exact procedure and the consultant you plan to see, and ask for any excess in writing. Self-funders can usually ask about finance, but terms depend on credit checks and should be read closely.

NHS colonoscopy is arranged for symptoms and through the bowel screening programme, with urgent suspected-cancer referrals aiming for diagnosis within 28 days. The routine NHS test is free to patients.

Many people consider private care because of NHS waiting times, but the NHS route costs nothing at the point of use and the 18-week standard applies to non-urgent consultant-led pathways. Local performance varies.

After sedation you need an escort home and no driving that day. You may feel bloated for a few hours, and you can normally eat afterwards and return to work the next day.

The risks below are the ones that can turn a quoted price into a larger bill, so ask how each would be dealt with.

• Bowel perforation and bleeding after polyp removal are uncommon but serious, and may need admission or surgery; ask what your quote and insurance cover in that case.

• Poor bowel preparation can make the examination incomplete and require a repeat, which adds cost, so follow instructions closely.

Write the answers down as you go. These are the questions that tend to separate similar-looking quotes for this procedure.

• Does the price include polyp removal if polyps are found?

• Is bowel preparation supplied and what type is it?

• Are pathology fees included?

• Who is the endoscopist and what are the consultant and anaesthetist charges?

• Is every fee in the quote guaranteed, or could consultant and anaesthetist charges differ from the estimate on the day?
