The answers below are short; each topic has its own page with the figures and the sources. The questions reflect the area: 19,096 households across the three councils relied on oil or LPG alone in 2021, and those homes have the most to gain and the most conditions to check.
If your question is about a particular home, the route finder may answer it in five clicks. If not, the form at the bottom of the page reaches the publisher, who replies by email.
