Monitored by the Drinking Water Inspectorate, this new measure is focused on maintaining the quality of your treated drinking water.
Compliance Risk Index looks at the significance of the failure, the cause, how we investigated it, the mitigation put in place, where the failure happened on our water supply system and how many customers were impacted.
If a failure happens, we are investigated and scored and if our total score for the year is between 2.00 and 9.50 we will be required to pay an underperformance penalty. The penalty amount will depend on the score.
Unlike many other measures we report against, the lower the score the better.
How have we performed?
In 2022/2023 we scored 1.49. This marks a continuation of last year’s excellent performance and a second year below the Ofwat dead-band of two for this measure.
We have continued to drive improvements in performance across all our assets through a combination of targeted investment and process optimisation. We have an ongoing programme of hazard review investigations at our key sites to identify further opportunities for improvement over the coming years.
We performed significantly better than the industry average of 5.1 and our continued excellent improved performance means we did not incur any financial penalty.
