We were the first water company to reduce bills for customers by introducing tariffs for those on the lowest incomes.

Our well-established partnerships include a network of trusted affordability and vulnerability charities in our region who have worked with us to deliver ever-increasing levels of support to vulnerable customers.

Introduced with the support of our customers and stakeholders, we offer the following three social tariffs:

• Assist which provides large bill discounts to customers on the lowest incomes
• WaterSure Plus, which provides an increased discount to customers with unavoidable high water use
• Pension Credit which provides an average 20% discount to customers of pensionable age who have no income other than the state pension.

From our experience of providing assistance to customers for over a decade, we know that to make improvements to customers' wellbeing the support we offer needs to be meaningful.

We are seeking a definition change to this commitment that reflects the reduction in customer bills following our final determination from Ofwat, the water regulator.

* Total bill reduction to customers receiving a social tariff, divided by the number of residential customers, expressed as £ per 10,000 households.
