Determinations and decisions


We are approving this Change Proposal. CPW141a seeks to clarify definitions of 'visual' and 'remote' meter reads in the market codes to ensure that outputs from smart meters and add-on devices can be used in the market. This change will help provide customers with more accurate and timely bills based on actual meter reads rather than estimated usage. Ofwat has consistently highlighted that poor quality customer, consumption and asset data can significantly undermine the customer experience and is one of the three main 'market frictions' that are preventing the market from working effectively and delivering better outcomes for customers. We therefore consider that this proposal will help improve quality and accuracy of data in the market, which will benefit the customer experience.
