Your postcode indicates you live outside the main boundary for registration at St Philips Medical Centre, however, you may register with us as an Out of Area Patient.

“
Registering at this practice as an “out of area” patient.
” +
“
As you live outside the Practice area (catchment area), we are not required to provide you with home visits.
” +
“
You may, on occasion, develop an urgent illness or injury at home which means that attending the GP surgery as normal would not be appropriate.
” +
“
If you require a GP, please contact this practice in the first instance. If we determine you need access to services local to where you live, we may ask you to call NHS 111.
” +
“
In these circumstances, NHS 111 will direct you to the local service that has been established by NHS England for patients such as you. This local service could be a GP practice near to where you live, the local walk-in or urgent care centre, A&E, or minor injuries unit.
” +
“
The local services will then decide if you can attend for an urgent face-to-face appointment with a healthcare professional, or if a home visit is needed, which will be based on your individual circumstances.
” +
“
If this is in the out-of-hours period when the surgery is normally closed between 8.30 and 18.30 am weekdays and during weekends – NHS 111 will direct you to the local out-of-hours provider.
