It’s important that our business customers are satisfied with the service they receive from us. By measuring this, we can keep improving what we do.
BR-MeX gives us a combined score for the average business customer service experience based on:
- Business Customer Experience survey (B-MeX)
- Ofwat randomly samples a minimum of 75 customers each month who have contacted us. Each interviewee gives us a score out of 10. These are then converted to a score out of 100.
- Retailer Experience survey (R-MeX)
- A twice-yearly MOSL sends a survey to retailers regarding our wholesale performance, covering engagement, communication and data quality. Retailers provide MOSL a score out of 10 which is converted to an average score from 0 (lowest) to 100 (highest).
- Market Performance Framework metrics
- Based on industry measures of wholesaler performance.
- Based on industry measures of wholesaler performance.
As the Business Retailer Measure of Experience (BR-MeX) is a new metric for this reporting year, no prior target existed, however we are aiming to be ranked 9th.
How have we performed?
Our performance for 2025 / 2026 is not where we want it to be. We are currently ranked in the bottom quarter of the table. Our objective is to achieve a minimum mid-table performance.
Improvement Strategy:
Retailer and customer engagement
- Structured online platform: Enhanced the online portal with a query-driven contact form to seamlessly route customers and retailers to the correct communication channels.
- Account management: Conducting ongoing, dedicated account meetings with retailers who require structured engagement.
- Dedicated staffing: Appointed a specialised Non-Household (NHH) communication officer to streamline relations.
Compliance and operations
- MOSL Alignment: Maintaining strict, full compliance with Market Operator Services Limited (MOSL) requirements for managing both planned and unplanned events.
- Internal Alignment: Executed an internal team restructure to support these operational shifts.
