How we know
A home needs an energy certificate (EPC) before it can be sold or let. When more certificates are lodged in a sector than usual, more homes tend to come to market there in the months that follow. We count them every month for every postcode sector in England and rank each sector against the rest of its postcode area.

How accurate is this? Tested on Coventry (CV) and Birmingham (B) postcode sectors, May 2011 to Feb 2025: this call picked the busier sectors 55 times in 100 over the next six months, against 49 for assuming last year's trend carries on. A useful lean, not a certainty.
