If the person is not displaying a blue badge, and your bay has an upright sign (indicating that it is an enforceable bay) please contact parking services to report the issues. Parking attendants will be asked to attend.
If the bay is not yet enforceable, please contact email@example.com to report the problem.
With your permission we can write to your neighbours asking them to be respectful of the bay, but we will not be able to take any immediate action until the bay is included with a TRO. We may however be able to advise you on timescales for this.
If the bay is being utilised by someone else with a blue badge, then we cannot take any action immediately please contact us on firstname.lastname@example.org to discuss options, but please be aware that any action would require a change to the Traffic Regulation Order (TRO).
