Why this site exists
Advice about home energy is scattered across government websites, regulators, manufacturers, installers and comparison sites. A good deal of it is trying to sell you something. We gather the facts in plain English, so you can decide what is right for your own home.
Who pays
No manufacturer, supplier or installer pays to be listed or written about here. None of them has any say over our content.
Where our facts come from
Every figure and claim on this site cites its source. We put official and independent sources first: government departments, Ofgem and other regulators, and consumer bodies such as Citizens Advice and the Energy Saving Trust. For product details we use manufacturers' datasheets. Each page lists its sources at the end.
How our pages are made
We research each page from those sources. Before publication, automated checks test every claim against its sources and reject anything the sources do not support. We keep a stored copy of every cited source, so each claim can be traced.
Our pictures
The illustrations on this site are made for us. Photographs come from the organisations named in their credits.
This is not advice
We offer general information only. It is not financial, legal or electrical safety advice. For a decision about your own home, speak to a qualified installer, your supplier or an adviser.
Corrections
If you spot an error or something out of date, please tell us through our contact page. We check every report against the sources and correct the page when we are wrong.
