Everything you use, eat, travel and buy over a year, counted wherever in the world it happened. About four minutes, and you can answer “I don’t know” to anything.
Four minutes. You will get a figure for the year and the three changes that would move it most.
Not started
A conversation about your house: its age, walls, heating, bills. Then a report of what is worth doing, what it costs and what it saves. About fifteen minutes.
You will need a recent energy bill. You will get costed measures for your house, with what each one would save.
What it adds up to
The two tools measure different things on different boundaries, so they do not simply add together. Here is each on its own, then the one place they genuinely meet.
Your figure for the year will appear here, split across home energy, travel, food, what you buy, and everyone’s share of public services.
What is worth doing to your house will appear here, with what each measure costs after grants and what it saves a year.
Once you have answered the footprint questionnaire, this is where we show what your home report would do to it.
