Draught-proofing for Barnet properties
Our Greater London coverage takes in Barnet (EN5) and nearby Hadley Wood, Finchley and Muswell Hill. It is roughly 11 miles north of London.
Where a Barnet home also has empty cavity walls, we can survey those at the same time. We check ventilation as carefully as insulation in Barnet homes, because both matter for keeping a house dry.
For regulations, if cavity wall insulation follows in Barnet, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
Funding in England
In England, ECO4 runs to 31 December 2026 and Warm Homes: Local Grant supports low-income households through councils.

Ventilation still matters
Trickle vents, air bricks and extractor fans are there for a reason. We seal accidental gaps, not the ventilation your home needs to keep condensation down.
