Receptionists provide an important link for patients with the practice and are your initial contact point for general enquiries. They can provide basic information on services and results and direct you to the right person depending on your health issue or query. Receptionists make most of the patient appointments with the GPs and nurses. They also perform other important tasks such as issuing repeat prescriptions and dealing with prescription enquiries, dealing with financial claims, dealing with patient records and carrying out searches and practice audits. The role is often very demanding, so please be patient. Our receptionists will only ask for details of your illness or problem to help direct you to the most appropriate resource.


Our administration team including our Practice Secretaries and Data Quality Team work hard behind the scenes dealing with incoming registrations & letters, coding, online access, referrals, letters to patients and organising the invitations for chronic disease reviews, blood tests, immunisations and smears, plus more besides.
