BID levy is to be imposed in a business improvement district only for periods (“chargeable periods”) falling within the period in which BID arrangements are in force in respect of the district.

The length of any chargeable period, and the day on which it begins, are to be such as may be specified in the BID arrangements.

BID arrangements must specify the description of non-domestic ratepayers in the business improvement district who are to be liable for BID levy for a chargeable period.

A person is to be liable for BID levy for a chargeable period if he falls within that description at any time within the period.

The amount of a person’s liability for BID levy for any chargeable period is to be determined in accordance with the BID arrangements.

Any amount of BID levy for which a person is liable is to be paid to the billing authority which made the arrangements.
