Straight answers to the questions people actually ask

Each guide answers one question a homeowner asks before they are ready to hand over a postcode — what something really costs, who qualifies, what happens next. The answer comes first, the government or Ofgem source is named beside every figure, and the date we last checked is on the page. They are for people still deciding; the survey is for people who have.
