Published prices

Published UK prices range from about £425 at an injection clinic to about £2,319 for a hospital package with X-ray guidance. Some hospitals quote the hospital fee only, with consultant fees and sedation on top.

Providers that publish prices include Complete Injections (London), Cromwell Hospital (London), One Stop Healthcare, London Pain Clinic (Weymouth Street Hospital) and Spire Southampton.

Prices change and depend on what is included, so ask the provider for a full written quote before you book.

These are guide or “from” prices from the providers’ own pages. Always ask for a written quote.

What to check before you pay

  • Is it a diagnostic (local anaesthetic) or therapeutic (steroid) injection?
  • Are the consultant, imaging and sedation included?
  • What happens next if it helps, and what would that cost?
  • What exercise or physiotherapy plan goes with it?

Frequently asked questions

Is SI joint radiofrequency treatment available privately?

Yes. One London clinic lists a separate consultant fee and a charge for the probe, on top of hospital fees. Ask for a full written quote.

What usually comes first

Low back and buttock pain from the sacroiliac area is usually managed first with advice to stay active and exercise. Some NHS policies that fund sacroiliac injections expect conservative care to have been tried first.

A physiotherapist can tailor an exercise plan to you.
