You can be registered as a temporary patient for up to three months. This will allow you to be on the local practice list and still remain a patient of your permanent GP.
To register as a temporary patient simply contact the local practice you wish to use. Practices do not have to accept you as a temporary patient although they do have an obligation to offer emergency treatment. You cannot register as a temporary patient at a practice in the town or area where you are already registered.
If your usual residence is outwith the UK, please bring your EHIC card along with you. For normal residence outwith Europe there may be a charge.
