Responses to Data Cleanse Request for Information 

As part of the Market Performance Operating Plan (MPOP) 2020/21, MOSL committed to delivering a data cleanse plan for core market data items.

We issued a Request for Information (RFI) in October 2020 to inform the planning and prioritisation of the data cleanse activity. We received responses from 14 wholesalers and 10 retailers, which provided 97 per cent coverage of the market based on aggregate share of supply points. Today we are publishing a summary of responses from trading parties.

The RFI consisted of ten questions covering the three core groups of data contained in the Central Market Operating System (CMOS):

  • Customer details and premises data
  • Meter location data
  • Meter details data.

An overview of the responses is below, with more detail available in the response document:

Overview

  • Respondents welcomed the focus on addressing core market data issues and were broadly supportive of the approach; the focus on the key data items identified; and the proposals outlined to address data quality issues
  • Some wholesalers questioned the value of ensuring completeness of unique property reference number (UPRN) and valuation office agency (VOA) reference data; however, the responses to the RFI have provided strong evidence that these premises data items are crucial for facilitating the fulfilment of core market obligations and activities
  • The absence of occupancy status and Yearly Volume Estimates (YVE) from the scope of data cleanse was noted by some wholesalers; however, we can confirm that they are within scope for broader market improvement activity but have not been included here as they are already being addressed or investigated as part of other ongoing work.
  • 80 per cent of retailers (eight responses) and 71 per cent of wholesalers (14 responses) said they are adversely impacted by poor-quality customer and premises data, aside from the impacts already identified in MOSL’s analysis
  • Based on the RFI responses, we estimate the lower-bound annual resource to the market from managing poor quality data to be £10m; with customer and premises details accounting for 39 per cent of this cost, meter location data 42 per cent and meter details data 19 per cent
  • Trading parties are deploying resource to obtain and verify missing or inaccurate data items, administer bilateral requests, manage consistency and mismatches between central and internal systems, resolve inaccurate or incomplete supply point data, address high volumes of failed meter reads and manage meter verification requests.

You can find the full RFI questions and responses here. We have excluded responses to question two as they include confidential financial information

We will be using the information gathered alongside our own analysis to populate a full data cleanse plan for the next 12 months. This plan will be shared in March 2021.

If you have any questions regarding this RFI, please contact Luke Austin.
