Need the Windsor surgery details quickly?
If you are checking a phone number, planning a journey, working out whether the surgery is open, registering with the practice or trying to reach the correct Clarence service, the first job is making sure you have the Windsor practice rather than another surgery with a similar name.
The NHS and CQC identify this GP practice at Vansittart Road, Windsor, Berkshire, SL4 5AS. Reception is listed on 01753 865773.
Phone and Address: Check These First
“Clarence Medical Centre” is not a unique name in the UK. Search results can also surface practices in Wales and overseas, so checking the Windsor postcode before phoning or travelling prevents an easy but frustrating mistake.

If you are comparing contact and opening arrangements elsewhere in Berkshire, our Strawberry Hill Medical Centre patient guide explains a different Newbury GP access model and shows why “open” should not automatically be read as “walk-in GP available”.
Appointment and Online-Service Routes
The NHS Clarence Medical Centre profile links patients to the official surgery website and also provides access to NHS online health and prescription services.
The Windsor NHS profile does not clearly publish one named online triage product on the information available to this guide. Rather than guessing, use the current official practice website, the NHS App / NHS account where enabled, or reception on 01753 865773.
Call 01753 865773 during the listed reception hours. Be ready with the patient’s basic identifying details and a short explanation of what help is needed.
The NHS profile links to online health and prescription services and the NHS App. Available functions depend on what the practice has enabled for your account.
Use NHS 111 for urgent non-life-threatening help. Use 999 for a life-threatening emergency.
For a nearby example of a practice where the distinction between NHS App access and online appointment requests is especially important, see our Studholme Medical Centre NHS App and online-access guide .
How to Register as a New Patient
The current NHS profile says Clarence Medical Centre is accepting new patients. The NHS registration page for this surgery also provides a postcode-based catchment check and an online registration route.
Check the practice catchment first
Open the NHS registration page and enter your postcode. Most GP practices accept patients who live within the area they cover.
Prepare the information the NHS form asks for
The NHS registration page says you may be asked for your name and address, previous GP details, NHS number if known, emergency contact, carer details, medical history, allergies, current medicines and a phone number or email address.
Use the NHS online registration route
Complete the Clarence Medical Centre NHS registration page and follow its link to the national registration service.
Know what is not required merely to register
The NHS page says you do not need proof of address, immigration status, ID or an NHS number to register online with a GP.
If online registration is not suitable
The NHS page says you can check the practice website, phone reception on 01753 865773 or visit the surgery to collect a registration form.
Repeat Prescriptions and NHS App Access
The NHS Clarence Medical Centre profile specifically links to online health and prescription services and the NHS App.
NHS online services can support tasks such as repeat-prescription ordering, viewing parts of your GP record, checking results and managing appointments where the practice has enabled those functions.
If you already have NHS login
Open the NHS App or NHS website account and check which Clarence Medical Centre functions are available to you.
If the option you need is missing
Check the official practice website or ask reception which current prescription or online-service route should be used. Do not send medication details to MedicalCentreUK.org.

Before Travelling to Vansittart Road
- Check that your message or booking actually says Clarence Medical Centre, Windsor, SL4 5AS.
- Do not assume reception opening means a clinician can see you without an appointment.
- Check the official practice website or NHS profile before a bank-holiday or time-sensitive journey.
- If you are a Royal Holloway student, make sure you are following the campus GP route rather than the Windsor main-surgery number.
- If you need a particular accessibility arrangement, contact the practice before travelling rather than relying on an old third-party listing.
