The average Scottish Water household charge in 2016/17 is £351, £22 above the lowest - Severn Trent Water at £329 - while the highest is South West Water at £488.
Douglas Millican, chief Executive, said: “In the next year, Scottish Water will continue to provide our customers with one of the UK’s best value water and waste water services.
“Our charges have fallen in real terms in the last six years and will have dropped further by the end of our current regulatory period in 2021.
“Charges allow us to maintain investment – ensuring we continue to provide fresh, clearer drinking water for our customers, while protecting and enhancing the environment and supporting the Scottish economy. At the same time, we are taking steps to build an increasingly reliable and resilient service.
