144.Subsection (2) of section 21 makes amendments to section 30 of the 2002 Act which gives the Scottish Ministers the power by order to set maximum charges that may be recovered by a person other than Scottish Water for supplying water or providing sewerage services with the help of Scottish Water to others who are not the direct customers of Scottish Water. For example, the owner of a caravan site may be the direct customer of Scottish Water, and might in turn charge individual caravan owners for Scottish Water’s services subject to any relevant maxima. The amendments provide that in future the maximum charges for these services, or the method of calculating them, will be set out in Scottish Water’s charges scheme under the new section 29A of the 2002 Act (see above) and consequently will be subject to approval by the Commission.
