Gastric sleeve surgery cost in the UK: what you pay privately (2026)

Private gastric sleeve surgery removes most of the stomach through keyhole surgery, leaving a narrow tube, to reduce how much food can be eaten and alter hunger hormones, as a treatment for severe obesity when diet and exercise have not been enough.

Some private hospitals post guide prices for common procedures. For gastric sleeve surgery the entries we found ran from £11,189 to £12,130. Each row below is a published figure from the named provider, and the label shows the exact variant it priced.

Hospitals update these lists, and a guide price is not a quote. Treat the figures as a way to see the scale of the bill, then compare against a written estimate for your own case.

Under general anaesthetic, the surgeon removes most of the stomach through small cuts and staples the remainder into a narrow sleeve. The operation takes around an hour or two.

Ask what the pre-operative programme involves, what aftercare is included for how long and how complications would be handled and billed.

Price differences for gastric sleeve surgery usually come down to a handful of choices and circumstances, set out here.

• Hospital fee and stay: Ramsay Park Hill lists gastric sleeve at £11,189, Springfield at £11,341 and Duchy at £12,130 in the lists we retrieved.

• Surgeon and anaesthetist fees: these may be separate from the hospital fee at some providers.

• Pre-operative programme: dietitian, psychology, bloods and scans usually precede surgery and may be billed separately.

• Aftercare: dietitian reviews, blood tests and vitamin supplements continue for life.

• Complications: leaks, bleeding or the need for revision can add cost.

The same label can mean different things at different hospitals. Use this table as a checklist when you read an estimate.

Insurers may cover bariatric surgery if you meet criteria and have the right policy, but many exclude weight-loss surgery, so check authorisation in advance.

Policies differ on outpatient and inpatient cover, so the same procedure can be fully, partly or not covered. If you pay yourself, ask what is guaranteed in the price and whether instalment plans carry interest.

The NHS funds bariatric surgery for people who meet NICE criteria and have tried other treatments, with access varying by area and long waits in many places.

The NHS pathway runs through your GP and a consultant-led service, with an 18-week referral-to-treatment standard for non-urgent care. If a wait looks likely to exceed that, you can ask your commissioner about alternatives.

Most people stay a couple of nights, follow a staged liquid and soft diet over weeks, return to desk work in a couple of weeks and attend regular follow-up visits.

Most people have an uneventful experience, but it helps to know how a problem would be handled financially.

• Serious complications such as staple-line leak or bleeding are uncommon but can mean a long stay or further surgery; ask what the provider covers and for how long after the operation.

• Surgery is a tool that requires permanent changes in eating, and lifelong vitamin supplements and monitoring are essential.

To compare like with like, request the same details from every provider. For this procedure the useful questions are below.

• What is included in the price, including surgeon and anaesthetist fees?

• Which pre-operative tests and appointments are included?

• What aftercare is included and for how long?

• What happens if I need revision or have a complication?

• Does the quote itemise the hospital, consultant and anaesthetic charges, and which of them could still change?
