External wall insulation (EWI) can dramatically improve your home’s thermal efficiency, reduce energy bills, and enhance kerb appeal. But without proper planning and professional workmanship, it can also introduce unexpected challenges, most notably, moisture and damp. Reports of damp after external wall insulation have recently risen across the UK, often linked to poor installations or subpar materials.

Upgrading your home with external wall insulation is one of the most impactful ways to enhance comfort, reduce energy bills, and improve your property’s value. If you are a London homeowner considering energy-efficient upgrades, understanding when to apply for EWI grants in London is as crucial as knowing how to apply. Timing can determine your eligibility, your funding success, and ultimately, how much you save.

For homeowners living in classic London homes, breathable external wall insulation (EWI) is fast becoming the go-to solution. Not only does it maintain the character of older buildings, but it significantly improves energy efficiency without trapping moisture, a common issue in solid brick walls.
