MOSL has published its draft 2025-28 Business Plan which sets out the delivery of its core services, key improvement programmes and the associated budget for 2025/26.

We are consulting on the draft plan with members and seeking feedback on:

  • The proposed level of Market Operator (MO) charges
  • The phasing of the improvement programmes
  • The proposal to introduce a new Strategic Data Programme

Our proposed MO charges in 2025/26 are £13,400K - a 1% decrease on 2024/25. Total expenditure of £13,645k includes £245k funded from reserves. A further £300k is proposed through the Strategic Data Programme, which, if added to our budget, would be funded by both wholesalers and retailers.

The new Strategic Data programme is designed to address the root causes of poor data entering the market. It will focus on market processes, codes and structures that might be preventing good quality data from entering the central system and will run in parallel to the data assurance BAU service.

Key budget headlines:

  • MO charges are proposed to decrease by 1% (versus 2024/25, without the optional new programme)
  • The key driver for the fall is the one-off additional charges for MPF Reform which affected 2024/25
  • This is partly offset by the impact of BR-MeX (specifically B-MeX surveys which is a new obligation for MOSL to carry out) and inflationary pressures (including pay rises and higher employer’s national insurance)
  • We have offset other cost increases with efficiency savings and prioritisation of spend
  • Wholesaler-only data assurance charges will not continue – total wholesaler charges will therefore fall by 7%

Our plan has been designed to deliver our strategic priorities and support the Panel in the delivery of its Roadmap to a Flourishing Market.

We consulted on the draft plan with the Strategic Panel in November. In its formal response letter, Trisha McAuley, Panel Chair said “Panel Members continue to see a general benefit where a central provider such as MOSL can provide value through enhanced services. While this may result in an increase in costs at the centre, it can be more efficient than a distributed delivery across the market. With this in mind, the Panel continues to support MOSL’s strategic principle to focus on delivering services where it is best placed to support trading parties and help the market flourish”.

MOSL’s CEO, Sarah McMath, says “Our plan is designed to be transparent. What we want for the market is what we strongly believe is in the best interests of members and business customers. With your trust and support, we can deliver faster, more efficiently and plan more effectively for the long-term.”

The consultation with trading party members will run from 13 January to 27 January.

We will then review and collate responses and incorporate feedback, where required, prior to publishing the final plan for member approval in February.
