Chelmsford is part of BMI group, so they are all much of a muchness to be honest, most private hospitals operate in the same way. Best thing to do (in my opinion) is pick your surgeon first, they will all operate at a few differing venues and then pick the hospital that is most convenient, remembering how handy it will be for aftercare. Best way to find out what's what is ring and ask to speak to surgeon's secretary, they know everything....and will talk you through process. Good luck!
