There are a number of requirements in Section S of the BSC that must be met before a Supplier can treat a site as a Long Term Vacant site. One of these requirements is that their Non Half Hourly Data Collector (NHHDC) must make two visits to the site to confirm they cannot obtain a reading as the site is not occupied. These two site visits must be ‘not less than three months and not more than seven months apart’. P245 Alternative Modification changes this requirement to “not less than 75 calendar days and not more than 215 calendar days apart”, additionally moves all the Long Term Vacant timescale details from the BSC to BSCP504; describes these timescales in BSCP504 in terms of calendar days; and clarifies the wording of BSC Annex S-2 paragraph 4.3.20.


P245 was raise by E.ON on 23 October 2009.The Authority approved P245 Alternative Modification and it was implemented on 31 March 2010.
