Method
A census share is the count of households in a category divided by the borough's total households, rounded to one decimal place, or two for small categories. "All flats" adds purpose-built flats, flats in converted houses, flats in other converted buildings and flats in commercial buildings. The off-gas share is the government's published 2024 figure. A grant rate divides the Boiler Upgrade Scheme count by the borough's households and multiplies by 1,000; the England and Wales rate does the same with the national count. Totals for Greater Manchester add the ten boroughs.
The census extracts are kept with the site's code so every figure can be rebuilt. The combined authority's page is quoted as it read on the day; where it named no delivery partner, the site says so.
What the sources cannot show
The census describes March 2021. The off-gas estimates count properties without a meter, not their fuel. The grant statistics count Boiler Upgrade Scheme vouchers paid, not heat pumps fitted by other routes, such as Greater Manchester's own Warm Homes scheme. None describes an individual home, and where the guide links two measures it says that the statistics give no reasons.
