Question 2 of 6
Where are the roofs?
A UK postcode, a street or a place. We check it against the twelve tiles we have actually flown.
We hold 4,744 roofs across twelve measured tiles, about 12 km². If your postcode is outside them we say so and match you against roofs like yours instead.
Question 3 of 6
How much roof are you responsible for?
This decides whether the brief totals one roof, a shortlist, or a whole measured area.
Question 4 of 6
What happens under the roof?
Building use is the cooling-demand benchmark. It genuinely moves the money figure, and for some uses it removes it.
Question 5 of 6
What is the problem you have to solve?
This picks which number leads, which evidence we show, and the colour mode the map opens in.
Question 6 of 6
What do you want to walk away with?
The closing artefact. Everything above it is already computed.
