45.This section amends section 54 of the 1980 Act, which makes provision regarding water meter accuracy, to alter the error threshold above which Scottish Water must refund any overpayments (or the customer make up any underpayments) resulting from the inaccuracy. The amended section provides that where a water meter registers incorrectly to any degree exceeding 2.5% (for high flow rate) or 6% (for low flow rate), a refund or payment (as appropriate) must be made. Those rates are substituted for the existing error threshold in the 1980 Act of 5%. The Scottish Ministers are required through regulations to define what constitutes high and low flow rates (and regulations may also amend either of the percentage figures).
