For NUAR to be a reliable and comprehensive source of information it is crucial that, from the outset, it also contains existing information which is already held in undertakers’ records.
	New section 106B establishes the concept of the "initial upload period", during which undertakers having apparatus in a street must enter into NUAR all information that is already included in their records on a specific date, referred to in this provision as the "archive upload date". Such undertakers must also, during this period, enter into NUAR any other information, held by the undertaker on that date, of a description prescribed by the Secretary of State in regulations.
	The Secretary of State may also, in regulations made under subsections (2) and (3) respectively, set out when this duty to enter information held in their records into NUAR does not apply, and the form and manner in which this information must be entered into NUAR for these purposes.
	Subsection (8)(a) imposes a duty on the Secretary of State to specify, in regulations, the "archive upload date" (on which a "snapshot" of relevant information in the undertaker’s records is taken). Subsection (8)(b) also requires the Secretary of State to specify the duration of the "initial upload period", beginning with the archive upload date, within which the information comprising that snapshot must be entered into NUAR.
	An undertaker who fails to comply with a duty imposed by section 106B commits a criminal offence which is triable summarily and, if convicted, can result in a fine.
