How I work on this site
Every calculator follows the published methodology, and I test it against the worked examples in the official documents where they exist. Every figure links to its source on the methodology pages. Each page shows when it was last reviewed. If a rule or price changes, I update the page and the date.
The sites are a personal project, separate from my day job. I don't take paid work through them, and no installer or manufacturer pays to be mentioned.
