Article 13 Ascertaining entitlement to reduced amounts
An authority may authorise a contractor for the purposes of calculating the chargeable amount in respect of any dwelling in the authority’s area to—
(a)
serve a notice on any person requesting information for the purpose of considering whether, by virtue of regulations under section 13 of the Act (reduced amounts), the person on whom the notice is served is liable to pay an amount in respect of council tax which is less than the amount it would be apart from those regulations; and
(b)
where information is supplied in response to such a notice, determine the amount, if any, by which the liability in respect of council tax of the person concerned is less than the amount it would be apart from those regulations.
