Last reviewed: August 2026. Prices are typical UK market ranges, not quotes. Suitability depends on your BMI and medical history — a balloon is not appropriate for everyone.
A gastric balloon in the UK costs £4,000 to £8,000. What you pay depends less on the clinic than on which balloon you choose and how long it stays in.
Gastric balloon prices in the UK by type
| Balloon | Duration | Typical UK cost | How it is placed |
|---|---|---|---|
| Allurion (Elipse) | ~4 months | £3,000 – £4,500 | Swallowed as a capsule — no endoscopy, no sedation |
| Orbera (6 month) | 6 months | £4,000 – £6,000 | Endoscopic, under sedation |
| Orbera 365 | 12 months | from £4,495 | Endoscopic, under sedation |
| Longer-duration balloons | 12 months | £5,000 – £8,000 | Endoscopic; price reflects duration |
The swallowable Allurion is cheaper largely because it avoids endoscopy and sedation on both insertion and removal — it passes naturally. That convenience comes with a shorter window: four months rather than six or twelve.
What the price should include
A balloon is not a procedure you buy once. The result comes from the aftercare programme wrapped around it, and that is where quotes diverge:
- Dietitian support — how many sessions, over how long, and are they in person?
- Removal — included, or billed separately? For endoscopic balloons this is a second sedated procedure.
- Follow-up appointments during the balloon period
- Early removal — a minority of patients cannot tolerate the balloon and need it out within the first fortnight. Ask what that costs and whether any refund applies.
A £4,000 quote with six months of dietetic support and a £4,000 quote with none are not the same product. Weight regain after removal is the main failure mode of balloon treatment, and structured support is what reduces it.
Is a gastric balloon available on the NHS?
Rarely. The NHS funds bariatric surgery under NICE criteria, but balloons are generally treated as a temporary, non-surgical intervention and are not routinely commissioned. In practice, almost all UK balloon patients pay privately.
For reference, NHS bariatric surgery criteria are a BMI of 40 or above, or 35–39.9 with a significant obesity-related condition such as type 2 diabetes. Waiting lists in England routinely run two to three years from referral.
Who a balloon actually suits
Balloons occupy a specific gap, and clinics are not always clear about where that gap is.
A balloon may suit you if your BMI is roughly 27–35, you need to lose 10–20 kg, you want to avoid surgery, or you need to lose weight before another operation.
A balloon is likely the wrong tool if your BMI is over 40 — expected loss is 10–15% of body weight, which will not resolve severe obesity — or if you are looking for a permanent solution. The balloon comes out. What happens next depends entirely on habits built while it was in.
This is the honest limitation of balloon treatment: it is a window, not a cure. Patients who treat those months as training tend to hold their loss. Patients who treat them as a diet tend to regain.
Balloon abroad: what actually changes
Balloons cost less in Türkiye — typically £1,800 to £3,000 including the balloon, placement and a short stay. The saving is real but smaller in absolute terms than for surgery, and one thing matters more here than with any other procedure:
The follow-up is the treatment. With a gastric sleeve, the operation does most of the work. With a balloon, the dietetic programme does. If you have the balloon fitted abroad and return home with no structured support, you have bought the cheaper half of a two-part treatment.
If you are considering it, ask specifically how follow-up works once you are home — remote dietitian sessions, how frequently, in what language, and who removes the balloon at the end. For endoscopic balloons, removal means a second trip or finding a UK clinic willing to remove a device it did not place, which not all will do.
The swallowable Allurion avoids that particular problem entirely, which is why it is often the more sensible choice for treatment abroad.
Frequently asked questions
How much does a gastric balloon cost in the UK?
£4,000–£8,000 depending on type and duration. The swallowable Allurion is typically £3,000–£4,500; Orbera 365 starts around £4,495.
How much weight will I lose with a gastric balloon?
Typically 10–15% of body weight over the balloon period, with results depending heavily on the support programme. It is not comparable to surgical weight loss.
What is the cheapest gastric balloon?
The swallowable Allurion, both in the UK and abroad, because it requires no endoscopy or sedation for placement or removal.
Does the NHS fund gastric balloons?
Not routinely. NHS funding covers bariatric surgery under NICE criteria; balloons are usually self-funded.
What happens when the balloon comes out?
Nothing automatically. Weight regain is common without sustained changes to eating habits, which is why the aftercare programme matters more than the price difference between clinics.
