About Allens Green
Small rural hamlet near Sawbridgeworth with a mix of off-grid and oil-fired heating systems.
Mix of period high-street properties, Victorian/Edwardian terraces, and modern executive estates around the station.
- Conservation area restrictions affect external flue siting on period properties
- Some streets have shared chimney stacks where flue routing needs coordination
- High Wych and rural fringes occasionally on LPG rather than mains gas
