The cost of a private colonoscopy in the UK ranges from around £1,849 at the most competitive providers to over £4,500 for an all-inclusive procedure. If you are over 50 and facing a routine NHS wait that could stretch to five months, knowing exactly what you will pay matters. As of December 2025, more than 71,000 patients were on the NHS colonoscopy waiting list in England. Nearly a third had been waiting beyond the six-week target. This guide sets out self-pay prices from named UK providers, the NHS vs private comparison for 2026, and what to ask before you book.
Key takeaway: The cost of a private colonoscopy in the UK starts from around £1,849 at Practice Plus Group, rising to £2,690 at Nuffield Health for a standard procedure. A fully all-inclusive package – covering consultation, sedation, biopsies, and follow-up – typically costs £2,500-£4,500. Private providers generally offer appointments within 3-10 working days, compared with NHS routine waiting times of eight weeks to five months.
Cost of a Private Colonoscopy: 2026 UK Prices by Provider
Private colonoscopy prices vary depending on the hospital group, its location, and what is included in the quoted price. The figures below are drawn from the LaingBuisson Self Pay Market Report (7th edition, May 2025) and verified against current provider websites in March 2026.
| Provider | Typical Self-Pay Cost | UK Hospitals | Notes |
|---|---|---|---|
| Practice Plus Group | ~£1,849 (fixed) | Multiple sites | Fixed all-in price; also delivers NHS endoscopy work |
| Independent hospitals | ~£2,050 | Varies | Prices vary; confirm all inclusions before booking |
| Ramsay Health Care | ~£2,291 | 29 hospitals | Consultation and procedure included |
| Circle Health Group | ~£2,424 | 54 hospitals | All-inclusive packages available |
| Spire Healthcare | ~£2,613 | 39 hospitals | Consultation, procedure, and sedation included |

London prices are typically 30-50% higher than the national averages shown above. HCA Healthcare, which operates exclusively in London, should be expected to quote above £3,500 for a standard colonoscopy.
Practice Plus Group consistently offers the most competitive pricing among major hospital groups. It delivers a high volume of NHS endoscopy work, which keeps per-procedure costs lower for self-pay patients. If keeping costs down is a priority, it is the first provider to approach for a quote.
Quick Facts
NHS vs Private at a Glance
On the NHS, colonoscopy is free but waiting lists can extend beyond four months. Private providers offer appointments within 1-2 weeks at a cost of £1,749 to £2,690, typically all-inclusive of consultation, sedation, and follow-up.
Key Questions to Ask Providers
Before booking, confirm that your quote includes: initial consultation, sedation, biopsies, histology (pathology) fees, polypectomy (polyp removal) if applicable, and a follow-up appointment to discuss results. Ask specifically about any additional costs for tests or travel.
All providers offer rapid online booking and can typically schedule your procedure within 1-2 weeks of your initial consultation. Contact your chosen provider directly for the most current pricing and availability in your region.
What May Not Be Included in the Headline Price
Not all colonoscopy quotes cover every element of the episode of care. Before committing, ask each provider specifically whether the following are included:
- Initial consultation: Typically £150-£350 if charged separately.
- Histology (pathology) fees: If a biopsy is taken, the tissue must be analysed by a pathologist. This adds £150-£400 if not bundled.
- Polypectomy: Polyp removal during the procedure; some providers include this, others charge separately.
- Anaesthetist-led sedation: If an anaesthetist (rather than a trained nurse) administers sedation, an additional £250-£450 may be charged.
- Follow-up consultation: To discuss biopsy results; typically £150-£250 if not included.
- Bowel preparation kit: Usually supplied as standard – confirm before your appointment.
A fully all-inclusive private colonoscopy – covering consultation, procedure, sedation, biopsies, histology, and follow-up – typically costs between £2,500 and £4,500 at most major providers. Requesting a fixed-price package rather than an itemised quote is the most reliable way to avoid unexpected charges after the procedure.

NHS vs Private Colonoscopy: Cost and Waiting Time Compared
The table below compares NHS and private colonoscopy across the factors that matter most when you are considering your options.
| NHS Colonoscopy | Private Colonoscopy | |
|---|---|---|
| Cost to patient | Free at point of use | £1,849-£4,500+ (self-pay) |
| Urgent referral wait | Up to 28 days (two-week-wait pathway) | Typically 3-10 working days |
| Routine referral wait | 8 weeks to 5+ months (varies by trust) | Days to 2 weeks |
| Access route | GP referral required | Self-referral available; GP referral helpful for PMI |
| Consultant choice | Assigned by NHS trust | Full choice of consultant |
| Sedation options | Standard sedation or Entonox | No sedation, nurse-led, or anaesthetist-led |
| Environment | Ward or shared recovery area | Private room; flexible scheduling |
| Results turnaround | Days to weeks | Same day or within 72 hours |
| Insurance cover | Not applicable | Often covered by PMI for new symptoms |
NHS waiting times are indicative based on NHS England data (December 2025). Individual trust waiting times vary. Private costs are self-pay ranges from named UK providers, verified March 2026.
For many people over 50, the decision to go private is driven primarily by speed. The NHS remains the right route for urgent referrals, and the two-week-wait pathway for suspected cancer is well-supported. Routine waiting lists, however, remain under significant pressure.
Does Private Medical Insurance Cover the Cost of a Private Colonoscopy?
Private medical insurance (PMI) commonly covers colonoscopy in the UK, provided the procedure is medically necessary and recommended by a GP or specialist. Insurers such as Bupa, AXA Health, Aviva, and Vitality typically cover the full cost for investigations of new symptoms. Cover is subject to your policy’s excess and outpatient limits.
However, there are important caveats that catch many patients out:
- Pre-existing conditions: Most PMI policies include a moratorium on conditions that existed before you took out the policy. If you have previously been investigated for bowel symptoms, have inflammatory bowel disease, or have had polyps removed, the insurer may classify a new colonoscopy as related to a pre-existing condition and decline cover.
- Routine screening: PMI does not cover colonoscopy carried out for routine screening purposes – only for the investigation of new or active symptoms.
- Pre-authorisation: Always contact your insurer before booking to obtain pre-authorisation. Without this, you risk liability for the full self-pay cost.
All the major private hospital groups – Nuffield Health, Spire, Circle Health Group, and Ramsay – work directly with the main PMI providers. Ask both your insurer and the hospital to confirm your cover before your appointment is booked.
What Is a Colonoscopy and What Does It Involve?
A colonoscopy uses a thin, flexible camera – a colonoscope – to examine the inside of the large bowel (colon) and the lower small intestine. The procedure is performed by a specialist endoscopist and typically takes 30 to 60 minutes.
Colonoscopy is used to investigate a wide range of bowel symptoms and conditions, including:
- Rectal bleeding or blood in the stool
- A persistent or unexplained change in bowel habits lasting more than three weeks
- Unexplained abdominal pain, bloating, or cramping
- Unexplained weight loss
- A positive result on an NHS or private FIT (Faecal Immunochemical Test) stool test
- Surveillance of known conditions such as inflammatory bowel disease, Crohn’s disease, or a history of polyps
If a polyp is found during the procedure, it can usually be removed at the same time (polypectomy). Tissue samples (biopsies) can also be taken and sent to a pathologist for analysis. Both steps add to the clinical value of the procedure. Make sure your quote specifies whether polypectomy and histology fees are included – these can add £200-£600 to the total if billed separately.
Sedation and Comfort
Most patients choose mild intravenous sedation, which induces a relaxed, drowsy state without general anaesthesia. You remain conscious but are unlikely to remember much of the procedure. Entonox (gas and air) is also available, and some patients opt for no sedation at all. If you have sedation, you will need a responsible adult to collect you and must not drive for the remainder of the day (NHS, 2024).
Bowel Preparation
Before a colonoscopy, you must take a bowel preparation solution (laxative) the evening before and on the morning of the procedure. A low-residue diet for one to two days beforehand is also required. This clears the bowel completely so the camera has an unobstructed view. Most patients report that the preparation is the most challenging aspect of the whole experience – not the procedure itself.
NHS Colonoscopy: Access, Screening, and Waiting Times in 2026
The NHS Bowel Cancer Screening Programme
In England, the NHS Bowel Cancer Screening Programme invites everyone aged 50 to 74 to take a home FIT (Faecal Immunochemical Test) every two years. The test detects traces of blood in the stool, which can indicate bowel cancer or pre-cancerous polyps when treatment is still most effective. From January 2025, NHS England expanded routine screening invitations to everyone from the age of 50, having previously started at 60.
In January 2026, the NHS lowered the FIT referral threshold from 120 to 80 micrograms of haemoglobin per gram of faeces. This means more people with early-stage changes will now be referred for colonoscopy (UK National Screening Committee, January 2026).
If your FIT result is abnormal, a bowel cancer screening nurse will contact you and arrange a colonoscopy referral through the programme.
NHS Referral Pathways
Two-week wait (urgent): If your GP suspects possible bowel cancer based on your symptoms, they can refer you under the two-week-wait pathway. You should be seen by a specialist within 14 days and receive your diagnosis or have cancer ruled out within 28 days of referral. In December 2025, 77.4% of patients met this 28-day standard, against a target of 75% (NHS England, February 2026).
Routine referral: Non-urgent patients – including those monitoring a known condition or with a mildly abnormal screening result – face considerably longer waits. As of December 2025, 71,265 patients were waiting for a colonoscopy in England, with 32.8% past the six-week target. At some NHS trusts, routine waiting times extend to five or six months.
If you have been placed on a routine waiting list, ask your GP for the current estimated wait at your local trust. Ask also whether you are eligible for referral to a neighbouring trust under the NHS Patient Choice framework.
What Are the Risks of a Private Colonoscopy?
A colonoscopy is a low-risk procedure when carried out by an experienced endoscopist, but it is not risk-free. Before you book – NHS or private – your consultant should discuss individual risk factors with you at the pre-procedure consultation.
- Perforation: A very small risk (approximately 1 in 1,000 procedures) of a tear in the bowel wall, which may require surgical repair.
- Bleeding: Minor bleeding at the site of a biopsy or polypectomy is not uncommon and usually resolves without treatment. Significant bleeding is rare.
- Sedation risks: Mild sedation carries a small risk of adverse reaction. If sedation is used, you must not drive and must have a responsible adult with you for the remainder of the day.
- Incomplete procedure: In a small number of cases the colonoscope cannot reach the full length of the bowel, and a repeat procedure or alternative scan may be required.
- Bowel prep discomfort: The laxative preparation causes diarrhoea and can cause dehydration. Patients with certain medical conditions should discuss the preparation protocol with their doctor beforehand.
The vast majority of colonoscopies are completed without complication. You can check a private consultant’s outcomes data via the Private Healthcare Information Network at phin.org.uk before booking.
Interestingly, there is research suggesting coffee may cut bowel cancer risk by half.

Frequently Asked Questions About Private Colonoscopy Costs
Can I get a private colonoscopy without a GP referral?
Yes. Most private providers allow self-referral for patients who are self-funding. You can contact a private hospital or clinic directly, complete an online consultation, and book a procedure without a GP letter. However, if you intend to use private medical insurance, your insurer will almost always require a GP referral letter as part of the pre-authorisation process. A GP referral also ensures that the results feed back into your NHS records, which is important for continuity of care.
How quickly can I get a private colonoscopy?
Speed is one of the main reasons patients choose to go private. An initial consultation can typically be arranged within one to five working days, and the procedure itself scheduled five to ten days after that. The entire process – from first contact to results – can often be completed in under two weeks. Compare this with routine NHS waiting times, which can extend to five months or more at some trusts.
Is a colonoscopy painful?
Most patients describe the experience as uncomfortable rather than painful, particularly during the bowel preparation phase beforehand. With sedation, the procedure itself is usually well-tolerated – many patients have little or no recollection of it afterwards. Without sedation, some patients experience cramping when the colonoscope passes around curves in the bowel. Mild bloating or wind after the procedure typically resolves within a few hours.
What is a virtual colonoscopy and is it cheaper?
A virtual colonoscopy (CT colonography) uses a CT scan rather than a camera to produce detailed images of the bowel. It requires the same bowel preparation as a standard colonoscopy, but no sedation and no camera insertion. Bupa offers a virtual colonoscopy (Colon Health Check) for around £1,069 – considerably cheaper than a standard procedure. There is an important limitation, however: if a polyp or abnormality is found, a standard colonoscopy will still be needed for biopsy or polyp removal. Patients with a family history or higher polyp risk will generally find a standard colonoscopy more cost-effective overall.
Will my results be shared with my NHS GP?
Private providers are not automatically required to share results with your NHS GP. Most do so as routine good practice, provided you give consent. Always ask your private provider to send the report to your GP. This ensures the findings are integrated into your NHS records and inform any future care.
What if a polyp is found during my private colonoscopy?
If a polyp is detected, the endoscopist will usually remove it at the same time (polypectomy) if it is small and safe to do so. The removed tissue is sent to a pathologist for analysis (histology). Make sure your quote specifies whether polypectomy and histology fees are included – these can add £200-£600 to the total if billed separately. Your consultant will advise whether a follow-up colonoscopy is recommended, based on the type, size, and number of polyps found.
Practical Next Steps
If you are waiting on the NHS
- Ask your GP for the current waiting time at your referring trust and whether referral to a neighbouring trust with shorter waits is possible under the NHS Patient Choice framework.
- If you were referred on the two-week-wait urgent pathway, you should receive a diagnosis or have cancer ruled out within 28 days. If that has not happened, contact your GP practice.
- If you received an abnormal FIT test result through the screening programme, you can contact the NHS Bowel Cancer Screening helpline on 0800 707 60 60 for guidance.
- Bowel Cancer UK (bowelcanceruk.org.uk) offers a free helpline and resources for patients awaiting investigation or diagnosis.
If you are considering going private
- Request a fully itemised written quote from at least two providers, confirming that consultation, sedation, biopsies, histology, polypectomy (if applicable), and follow-up are all included.
- If you have PMI, contact your insurer first to request pre-authorisation – before booking your appointment, not after.
- Check the consultant’s credentials via the Private Healthcare Information Network at phin.org.uk, which publishes outcomes data for private consultants.
- If cost is a primary concern, Practice Plus Group offers the most competitive fixed pricing (around £1,849) among established private hospital groups.
- For patients in London, budget for prices above £2,800 and compare quotes carefully between providers.
