reg 14 Screening decisions: timing
(1) The relevant authority must make a screening decision within— (a) 21 days after the later of the following dates— (i) the date on which the relevant authority receives the information referred to in regulation 12 (and, where relevant, a plan of the site of the development); and (ii) the latest date by which a local planning authority is required to give its views under regulation 13 or, if earlier, the date on which the relevant authority receives the last of those views; or (b) any longer period that may be agreed in writing with the developer. (2) But in an exceptional case (for example, relating to the nature, complexity, location or size of the development), the relevant authority may extend the date by which it is required to make a screening decision by notifying the developer in writing of the new date and the reason for the extension.
