The doctors are unable to take calls while consulting with patients, please leave a message with reception and the doctor will return your call when they are able to do so.

If you have an urgent issue please make an appointment to see the doctor.

Due to security reasons the doctor does not send or receive emails to or from patients, as normal email is not encrypted and therefore sensitive medical problems need a face to face consultation with the doctor.


In most cases an appointment is required for repeat prescriptions, referrals or results.

A list of our fees is on display in the waiting room.
