Water UK publishes a combined figure per company. The split between water and sewerage by company is not available from a primary source, only the national split of £309 and £330.
Ofwat's own website refused every automated request while this page was built. The Ofwat material here comes from the official press mirror, the CMA and gov.uk rather than from Ofwat directly.
There is no published year by year bill path for 2026/27 to 2029/30. Only the start and end points of the price review are official. Anything showing a year by year trajectory is somebody's projection.
Water company boundaries follow river catchments, not postcodes. Where we match a postcode to a company we say so is approximate, and where an area is split between two companies we show both rather than guess.
Bristol Water is no longer a separate company. Ofgem's water equivalent, Ofwat, terminated the Bristol Water licence on 1 February 2023 and varied the South West Water licence to cover the area, after Pennon bought the business. Separate price controls, and therefore separate charges, are kept for the Bristol Water area, which is why it still bills under its own name. Bristol Water's own charges scheme says so.
Averages are one number a year. What your company actually charges per cubic metre, per year and per pound of rateable value is on the water charges page, read from each company's own charges scheme.
