About Us

The mission of Prime Medicare Ltd. is to bring exceptional Digi-physical healthcare access to the people of Windsor, Reading, and Slough. We believe in the following three key ingredients:

  • Digital Front Door – To help you conveniently access us at a time of your convenience.
  • In-Person Services – To ensure physical examination and tests when required.
  • Doctor-Patient Relationship – To provide you with better-personalised care.

We believe that our Digi-physical healthcare model can deliver a seamless journey for our patients in their most testing times.

Our Remote-Only GP Appointments

Our founders have extensive experience in delivering remote-only GP services. Many healthcare conditions can be effectively treated and managed remotely.

We also offer our help to understand and navigate the available local services that are often valued by patients.

What is a Digi-Physical Service?

With Digi-physical, your first contact with a doctor is always through a ‘Digital-first’ remote appointment. If your doctor can safely treat you via video or telephone, they will do so. If, however, following your consultation you need (or want!) to see us in person, our doctor can book you into our ‘in-person services’ within our catchment area.

Our in-person services are provided via a combination of scheduled home visits to your door, and clinics.
