This dataset is available as machine-readable JSON — including provenance, columns, key figures and a verbatim sample of rows — and as a spreadsheet-ready CSV sample, for researchers, journalists and AI assistants. Every figure traces to the source below.
Methodology
Figures are the average annual household bill (water + sewerage) as published by Water UK for each appointed combined company, cross-verified against multiple independent republications on the fetch date. Only the 11 combined water + sewerage companies are included; water-only companies are excluded where secondary sources disagreed on the base figure. A real bill varies with metered usage, property band and any social tariff.
