In all fairness there are apparently 3 grades of skin removal surgery for the tummy part. If he is having to have his navel rebuilt and moved the surgery is quite a bit more expensive than the basic grade. I was told at the weekend that the London clinics are by far the most expensive in the UK and further north up the M1 the prices can drop significantly depending on where you go. Since he is in Kent London is probably the nearest place for him. He did see several surgeons before deciding which one to use.My neighbours daughter was as large as Jack and had weight loss surgery, she has been quoted £16k for skin removal.
Nobody knows for sure exactly what he is having done, if he's having any removed on his back etc that will bump things up.
We'll see if he comes up with the total cost and proof etc as he says he will.
