If you want to see a doctor, you’ll usually need to make an appointment. Most GP surgeries operate independently and have their own booking routines. Your surgery should be able to offer you an appointment to see a GP or other healthcare professional quickly if necessary. However, if it is more convenient, you should also be able to book appointments in advance. Familiarise yourself with your GP surgery’s appointment system, and try to plan in advance if you can.
