Hi. My 17 year old has been offered 2 days work shadowing a physiotherapist at a local NGS hospital. There have been a lot of forms to fill, including a vaccination form that they want signed off by a GP. We dropped this at the surgery, chased for it to be signed, and now they’re asking us for £30, for a ‘private referral letter’. Does this sound right, for a child, and an internal NHS communication (the info is also available on her NHS app)?
