Telephone numbers for services run by the county’s mental health and community services authority are changing.

Oxford Health NHS Foundation Trust said it has changed its phone system that will save £1m over five years.

It will cover 100 sites and 3,000 extensions in Oxfordshire, Buckinghamshire and Wiltshire, with Oxfordshire changes from September to January.

Old numbers will remain active and messages will give details of new numbers during the changeover.
