The Market Operator Services Limited (MOSL) has released its latest performance metrics for water retailers – and Castle Water has once again achieved the highest Market Performance Score (MPS) among the UK’s top 10 water retailers.
In June, we ranked first with an MPS of 98.10%, delivering both the highest number of completed tasks and the highest number of on-time tasks across the market.
In the latest results (July), our performance improved further to an outstanding 98.17%. This result confirms our position as the top-performing water retailer, setting the standard for reliability and accuracy in the business water market.
What This Means for Our Customers
Castle Water’s consistently high performance translates directly into benefits for business customers:
- More accurate billing through timely meter reads and fewer estimates.
- Faster issue resolution, reducing administrative delays.
- Improved water efficiency insights, allowing customers to spot unusual consumption patterns and potential savings opportunities.
These results demonstrate our ongoing commitment to service excellence, giving customers greater visibility and control over their water usage.
The Value of Our In-House Meter Reading Team
Unlike most water retailers, we operate our own in-house meter reading team. This unique approach enables closer control over service quality, higher accuracy levels, and faster turnaround times; all of which contribute to our industry-leading MPS performance.
Consistent Market Leadership
We have consistently topped MOSL’s performance tables, reflecting both our operational expertise and our customer-first approach. Delivering timely and accurate data isn’t just about meeting industry standards – it’s about providing businesses with the reliability and transparency they need to manage resources effectively.
