Key information regarding the age of meter read data, published by MOSL as part of our approach to support improvement in the market by providing transparent and open access to information.

Accurate consumption data is essential in helping business customers get the information, choice and services they need. Timely and accurate meter reading is vital in, ensuring that customers receive accurate bills from their retailers and that wholesalers can, in turn invoice retailers accurately for the water and waste services provided to their customers.

For metered premises, the Ofwat Customer Protection Code of Practice requires retailers to issue their customers with at least one accurate bill or invoice using a meter read each year. To meet code obligations, all meters are required to be read by retailers either monthly or biannually (i.e. at least once every six months).

Below each of the charts, you will find brief descriptions providing further information on what the charts are indicating.  Information regarding the source data for the charts is provided at the bottom of the page.

The chart above, ‘Overall market view’, shows the percentage of meters that had their last actual read within the past eight, 12, 16 or 24 months. It shows the position across all meters in the market at the end of each month since market opening.

Where a meter has not been read in more than 24 months, this indicates that it has not received a read since before market opening. 5% of the current 1.1 million meters in the market fall  into this category.

Since October 2018 retailers have been working on Data Improvement Plans with a particular focus on reducing the number of meters that have not been read in the past 12 months. The percentage of meters in this category currently remains above 15%, up from 7% at market opening.

We have also included the eight and 16 month milestones in this chart, as they are important cut-off dates in the settlement process between wholesalers and retailers.

MOSL tracks performance against the specific code obligations to read meters monthly or biannually and publishes this information every month through our reporting on Market Performance Standards.

The chart above, ‘Retailers over 5k’, shows, by retailer, the percentage of meters that had their last actual read within the past eight, 12, 16 or 24 months. The number above each bar shows the approximate total number of meters by retailer. This chart only looks at retailers with more than 5,000 meters in the market.

The chart has been ordered left-to-right by the percentage of meters not read within the past 12 months. This aligns with Ofwat’s requirement for a customer to receive an accurate bill or invoice using a meter read each year and the key metric that we have tracked trading parties against in their Data Improvement Plans.

The chart above, ‘Retailers under 5k meters’, shows, by retailer, the percentage of meters that had their last actual read within the past eight, 12, 16 or 24 months. The number above each bar shows the approximate total number of meters by retailer. This chart only looks at retailers with fewer than 5,000 meters in the market. Retailers with fewer than 20 meters have been excluded.

The chart above, ‘Wholesalers over 5k meters’, shows, by wholesaler, the percentage of meters that had their last actual read within the past eight, 12, 16 or 24 months. This chart only looks at wholesalers with more than 5,000 meters. The number above each bar shows the approximate total number of meters by wholesaler.

The chart has been ordered left-to-right by the percentage of meters not read within past 12 months.

The chart above shows, by wholesaler, the percentage of meters that had their last actual read within the past eight, 12, 16 or 24 months. This chart specifically covers wholesalers with fewer than 5,000 meters. The number above each bar shows the approximate total number of meters by wholesaler. Wholesalers with fewer than 20 meters have been excluded.

For consistency with the charts above, the chart has been ordered left-to-right by the percentage of meters not read within the past 12 months.

Further notes on the charts:

  • These charts have been made available to trading parties on a monthly basis since September 2018 to support data improvement activities. Trading parties are also provided the data underpinning the charts for their organisation at an individual meter level.
  • The source data for the charts is a monthly report (known as the ‘D1’ disaggregated settlement report), which is generated as part of the monthly settlement process between wholesalers and retailers. This provides a snapshot at the of each month – based on data held in the Central Market Operating System (CMOS) – of when every meter at an occupied premise in the market last had an actual (i.e. not estimated) read.
