You will deregister from the medical centre when you 'book out' of a regiment. When you do this, you will be asked if you would like to deregister your family (see below).
Your future unit will request your medical records; these will be sent to your new medical centre.
Dependants and entitled civilians
To deregister you will be asked to fill out a short de-registration form for you and any family members. You need to complete this in advance of your move, stating when you would like to be deregistered.
It is important that you deregister so that your medical records can be sent to your new medical centre.
What happens to my private medical records if I am posted back to the UK?
Your medical records are sent to the NHS Central Register in the UK. Your new GP surgery will request your medical records directly from the NHS Central Register.
