A zone is a fixed patch of about 60,000 households, sold to one installer per trade. While it's yours, we turn your competitors away.
Groups of postcode districts that add up to about 60,000 households: a few districts in a city, a market town and its villages in the country.
Each zone has an id, a map and a list of districts and towns. Your order shows exactly what you're buying.
The towns in your zone set the 40 questions we measure and the area pages we write.

Each zone is sold once per trade lane: domestic solar and battery, heat pumps, EV chargers, commercial energy. Rural zones come as an adjacent pair for the single-zone price. We won't sell a zone more than about 45 minutes from your base.
Add the next zone at 20% off. A second trade in the same zone is also 20% off.
Ask. We hold the zone in your audit for 14 days after we send it.
