How the figures are worked out
Shares are calculated from the counts, not copied from summaries. A census share is the number of households in a category divided by all households in the council, shown to one decimal place. The off-gas share is the government's own published percentage for 2024, shown to two decimal places as published. Rates such as grants per 1,000 households divide the grant count by census households. Totals for "the 14 councils" add the 14 council figures; totals for "the 12 districts" leave out Blackpool and Blackburn with Darwen.
The census figures come from the Nomis service's extracts of each table by council code, saved with the site's code so they can be rebuilt. The grant and off-gas figures are taken from the published releases for each council.
What the sources do not cover
None of these sources describes a particular house. The census is from 2021; the off-gas estimates count meters, not fuels; the grant statistics count vouchers paid, not heat pumps running; the listed-building dataset counts records, not homes. Where the site draws a conclusion from them, such as the link between off-gas shares and grants paid, it says that the statistics themselves give no reasons.
