Good things to write about

• A question about your home: how big a battery would match your evenings, whether backup would cover what you need, or where one might go. Tell us your yearly use and whether you have panels.
• Something we got wrong: name the page and the line. We check it against the source and correct every page that uses it.
• A newer source: PAS 63100 is being amended and Ofgem revises its typical use figures, so newer documents are useful to us.

What we can't do

We can explain the rules and the energy arithmetic. We can't inspect your home, sign off a location against PAS 63100, submit a network application or recommend a product; those need a qualified installer or your network operator. If you have a dispute with a firm about work already done, the consumer code it belongs to and Citizens Advice are the places to start, and we'll say so if that's the right answer.

How a correction is handled

We read the source again, change every page that relies on the figure or rule, and note the date on our references page. If the source hasn't changed and we think the page is right, we reply to explain why, with the reference, so you can check it yourself. Either way you hear back by email.

Before you write

Many questions are answered on a page already, and the search engines will find them faster than an email. The questions and answers page covers the twenty-one most common ones in a few lines each, and battery terms explains the vocabulary on specification sheets and quotes. If neither helps, write to us with as much detail as you are happy to share: your yearly use, any quote's usable size and power rating, and where you think a battery could go.
