Given the current rise in Covid-19 cases locally, Frimley Park Hospital have had to change their protocols about visiting in-patients. The following is taken from their website and this gives further details including phone numbers for different wards : click here
Visiting in person
If you wish to have an essential in-person visit with a family member or friend who is a patient, you must book an appointment by calling the relevant ward between 9am and 3pm . Our staff will check that a visit is possible and, if it is, will help to book an appointment.
The website also says :
Where possible please ring 111 before attending Accident and Emergency. 111 will be able to best direct you to get the medical treatment you require.
