Strategic Metering Review

The Water Report

At the MOSL CEO Forum in 2019, a number of trading parties raised concerns about the inadequate performance of metering assets and metering process to deliver cost efficient and robust services in the non-household market.

Metering was identified as a root cause of a number of issues in the market, leading to a poorer customer service, inaccurate bills and limited water efficiency uptake. As part of MOSL's three year rolling Business Plan we identified the Strategic Metering Review as a key improvement programme. The programme seeks to identify and implement a programme of metering-related improvement initiatives, with a focus on accurate and timely consumption data.

The Strategic Metering Review is being led by MOSL, supported by the Metering Committee. MOSL will drive delivery of the programme, but its success requires strong engagement with, and support, from the Strategic Panel and the wider market. MOSL is also actively liaising with other bodies to build strong and broad stakeholder support, including Defra, Ofwat, CC Water, the Retailer Wholesaler Group (RWG), UK Water Retailer Council (UKWRC) metering and communication suppliers and customer groups.

For an overview of the market, its challenges and the views of a number of stakeholders, we recommend reading the The Water Report's Special Report on metering, which was published in September 2021.

The programme of work is focusing on four key areas:

  1. A series of 'quick-start' projects that will develop solutions and change proposal to resolve some immediate issues facing the market (see below)
  2. A range of detailed projects developed with the Metering Committee that will address issues relating to incentives and behaviour, technology and data quality
  3. Associated operational strengthening through better use of existing procedures and processes to improve performance on issues such as long unread meters
  4. Strategic initiatives that could introduce change into the market, including reviewing meter-related roles and responsibilities and the assessing enhanced metering technologies

Quick-start projects 2022/23

A number of quick-start projects are currently underway, looking at:

  • How consumption data is accessed and shared*
  • Reducing meter read rejections (see analysis, findings and recommendations below)*
  • Improving the transfer read process*
  • Standard location details, including What3Words
  • Reviewing the definition of a 'visual meter reading'
  • New meter connection process
  • Wholesaler reads
  • Metering reading standards

*Continued from 2021/22


The Strategic Metering Review is expected to be implemented in a period of up to four years:

  • Work started on the initial tranche of quick-start projects in January 2021 and completed in March 2022
  • Other potential quick-start projects have been identified and will be prioritised for implementation during 2022/23 (see examples, above) and 2023/24
  • Strategic theme 1: Enhanced Metering Technology: MOSL commissioned an independent report on behalf of the Metering Committee to review the business case for investing in enhanced meter technology. The findings were published on 6 April 2022 and the full report, business case and templates to support trading parties' PR24 and Water Resource Management Plans are available below.
  • Strategic theme 2: Roles and Responsibilities: a second report, looking at options for possible changes to the current meter-related roles and responsibilities, is due to be published in early July. This, and the enhanced metering technology report will help drive future strategic projects, including items such as data sharing standardisation.

This page will be updated regularly as the Strategic Metering Review develops and we engage with stakeholders.
