£300 bill discount announced for UK households in first-of-its-kind schemeThames Water is identifying those living in 17 London boroughs who need financial support in order to automatically enrol them on its social tariff schemes. A new "first of its kind" scheme will give UK households £300 off utility bills. ‌Thames Water said the initiative will save around 33,000 struggling households more than £300 a year, or more than £10 million a year in total. ‌UK households set to benefit are those whose water bills exceed 5% of their net income. “Communities have our absolute assurance that no untreated sewage will enter the river … it is physically impossible by design,” said Thames Water.
