| CPW141 | Clarification of read definitions and meter chamber ownership |
This change consisted of two parts arising from quick start projects 6 and 10 from workstream 2 (improving meter reading processes) of the Strategic Metering Review. The Code Change Committee decided at its 12 April 2023 meeting that these two parts should be progressed and recommended separately: CPW141a - Sought to clarify definitions of 'visual' and 'remote' meter read methods so that the outputs from smart meters and add-on devices could be formally accepted in the market codes. This was recommended by the Code Change Committee on 7 June and Ofwat approval was received 5 July 2023. CPW141a was implemented on 25 August 2023. CPW141b - Sought to clarify wholesaler ownership and responsibilities for meter chambers to remove inconsistent approaches by wholesalers in repairing and replacing meter chambers. This part was recommended by the Code Change Committee on 11 October 2023 and and Ofwat approval was received 23 January 2024. CPW141b was implemented on 16 February 2024. A post implementation survey is open until 12 December 2025. |
