Telephone enquiry service opening hours
The Information Office telephone service is open between 10am-12 noon and 2pm-4pm (Monday to Friday).
We aim to answer emails within one working day of receipt and currently answer over 80 per cent within this target.
A telephone call often produces a speedier answer to simple queries.
