MOSL has published a summary of the responses to the consultation on its proposed Central Data Cleanse service which ran from 23 November until 7 December 2022. 

We would like to thank trading parties who engaged with us through the consultation, as well as the numerous conversations with stakeholders that helped develop our proposal for consideration. 

Overall, trading parties acknowledged the need for better data, but there was contention about the scale and cost of the challenge to address this, and a desire to prove the veracity of the assessment findings prior to committing to a central cleanse, at scale. There was also concern from a number of wholesalers about the precedent being set for funding the activities through wholesaler only Market Operator (MO) charges, particularly before work on the reform of the Market Performance Framework has completed.

Listening to member feedback, we have revised the proposal for year one, moving to a focused and sequential approach that will demonstrate the veracity of the data findings at each stage and help parties understand the full cost and impact of correcting the data. ‘Proof point’ one will be the review and cleanse of ineligible premises with "high confidence" and a proof of concept for a mix of address cleanse and enrichment use cases at smaller volumes. This approach mitigates the potential impact on retailers from a large-scale address and eligibility cleanse and reduces the costs of the service in year one to circa £550k (covering third party costs and MOSL resource).

In a letter sent to those wholesaler members who raised concerns, we clarified the detail of the service being proposed and our position that the central data cleanse will not set a precedent for future MO charges being levied on a particular member category. We have also set out our revised proposal, responding to member feedback, in our 2023-26 Business Plan, which will be published on 11 January for consultation.

MOSL CIO John Davies said: “Whilst we are pleased that the responses confirm that trading parties feel strongly on the need to improve data quality, we appreciate the need to demonstrate the reliability and value in the findings and the effectiveness of the service before committing to a full-scale cleanse. We also recognise the ongoing time and effort that trading parties are putting into improving the quality of their data and believe that the central service led by MOSL will only serve to complement and accelerate this. We are confident that the new phased approach will help mitigate members’ concerns. Ultimately the market needs better data, and this is one important component of us achieving that.”
