Which NHS trust covers the CR postcode?

CR postcodes are primarily served by Lewisham and Greenwich NHS Trust.

How much does private colonoscopy cost near Croydon?

Private colonoscopy in the UK typically costs £1,300–£2,800, with a typical price around £1,850. Most major UK cities have private hospitals from Spire, Nuffield, Circle, or HCA Healthcare offering this procedure with a typical wait of 2–4 weeks. Always confirm the exact total cost (including consultation, surgery, anaesthesia, follow-ups) before booking.

Will going private affect my NHS care if I live in CR?

No. You can self-fund private treatment without losing your place on the NHS waiting list and without affecting your future NHS care. Many patients use private providers to access faster surgery while keeping the NHS option as a free backup.

Can I be referred to an NHS trust outside the CR area?

Yes. Under NHS Patient Choice rules you can ask your GP to refer you to any NHS trust in England — not just the one closest to your home. If a trust elsewhere has a shorter waiting list, you can request a referral there. Travel costs for treatment further from home are your own responsibility.
