The NHS does not cover certain services and your doctor is entitled to make a charge in line with the BMA scale of fees to cover the costs of providing these services.
The services include certain medical examinations e.g. HGV licence, taxi license, employment medicals, driving insurance etc, as well as certain certificates e.g. private medical insurance claims, private sick notes, holiday cancellations etc.
A list of fees is available at reception.
The doctor does religious circumcision procedures privately. An appointment can be made through reception.
