For a home in Bristol, Wessex Water is the main regional benchmark. Its forecast 2026/27 household average is £695 a year.
Many homes receive water from Bristol Water and wastewater services from Wessex Water. Water-company boundaries can cross postcode areas and clean water may come from a different company than wastewater.
Monthly and weekly equivalent
The annual company average works out to £57.92 a month or £13.37 a week. Your payment plan may collect over ten rather than twelve months, so instalments can differ.
