These Regulations revoke and consolidate the provisions of the Water Industry (Charges) (Vulnerable Groups) Regulations 1999 and the Water Industry (Charges) (Vulnerable Groups) (Amendment) Regulations 2000, 2003 and 2005. They also provide for certain obligations of a water or sewerage undertaker under these Regulations to be discharged, if a water or sewerage undertaker’s charges scheme includes a social tariff pursuant to section 44 of the Flood and Water Management Act 2010 and where the individuals specified in regulations 2 to 4 of these Regulations would receive at least the same amount of assistance through the undertaker’s social tariff. These Regulations do not apply to any water or sewerage undertaker whose area is wholly or mainly in Wales.
