Data
Every series behind the Clock, as CSV. The files are regenerated by the same daily build that updates the dashboard, from the same figures — they cannot disagree with it. Each file's derivation is on the methodology page; citation formats are under Citing this site.
Files
Per-scheme files share one schema: year (the calendar year for
daily-settled schemes — CfD, constraints, BSUoS — and the published scheme or levy year,
labelled by its starting year, for the rest), cost_gbp (nominal pounds, as
paid), cost_gbp_2024 (the same series in 2024 prices, ONS CPIH, series L522).
The current year is a partial year. Amounts for indirect schemes are the estimated share
attributed to renewables — the attribution rules are
on the methodology page.
Each file begins with three # comment lines recording the source, licence,
build time and method;
most tools skip them automatically (pandas.read_csv(…, comment='#');
in R, read.csv(…, comment.char='#')).

| restatements.csv | Every source revision the engine has recorded: when a publisher restates history, it is logged here, never silently overwritten | — | — |
| corrections.csv | Corrections to our own published figures — every confirmed error: what was shown, what it now shows, and who found it | — | — |
The dashboard's own JSON (totals, timeseries, breakdown, meta) is published at the same stable URLs.
