Free EPC API and Met Office urban-heat data exist, but per-listing glazing ratios, orientation and overshadowing/canopy are rarely in listing copy — would require scraping floor plans or developer brochures that often aren't public, making the 'questions to ask the developer' framing more honest than a precise numeric score.EPC API Documentation | Property Insights ↗Defra Data Services Platform (indoor temp ML models from EPC) ↗
