"Visit to Out of Hours Unit"

Saturday on the Bank Holiday Weekend - called my GP surgery, but it was closed. Rang 111 and gave details. A doctor rang me back within the hour, and gave me an appointment. I received excellent care, and a prescription for treatment.

I remain a little confused as to how the four departments\options for out of hours consultation differ 1) Out of Hours (seems to require an appointment via 111}, 2. Urgent Care Centre, 3. Minor Injuries unit, 4. Walk in Unit (in Slough?) - none of these seem to be listed below, but the care was excellent!
