Try the Ordnance Survey Code Point Open. It has administrative district code and administrative ward code attributes you can join to ons codes to get the relevant information.
Ordnance Survey Open Names (open data) gives you postcode and populated place, where populated place is a city, town, village, or some other place where people live.
For example:
SW1A 1AA -> City of Westminster RG4 7LR -> Caversham OX1 1AA -> Oxford
