Castle Water CEO John Reynolds gives a first view of tariff changes for April 2026
We have had first sight on indicative water tariff changes for 1 April 2026. There is no clear pattern. Changes vary from +3% to +30% for some customers. And the variation in movement between water and waste is still high – waste charges reduce by 5.4% for Southern with water charges increasing by 18.4%. The devil is very much in the detail for individual customers – bizarrely, United Utilities has a 22% increase for Places of Worship.
