Funding & Eligibility

Warm Homes: Social Housing Fund

AirEx Floorvent is eligible under the Warm Homes: Social Housing Fund, supporting upgrades in social housing with EPC ratings of D or below. It offers a fast, low-cost way to improve energy efficiency in homes that are often hard to treat.

Because Floorvent improves SAP scores by 2 to 4 points, it helps landlords meet retrofit targets quickly and with minimal disruption. It’s ideal for suspended timber floors, often overlooked in retrofit planning but responsible for significant heat loss.

The product is BBA certified, PAS 2035 compliant, and delivers verified energy savings, helping social landlords access funding while improving resident comfort and lowering heating bills.

Local authorities can access funding through the Warm Homes: Local Authority Grant to deliver energy-saving improvements in eligible homes. Floorvent is well suited to this scheme due to its simple, one-hour installation and minimal disruption.

It targets heat loss through underfloor draughts and is suitable for large-scale delivery across older housing stock. It helps improve EPC ratings in line with decarbonisation plans and supports net zero targets.

Floorvent’s proven performance, verified energy savings, and PAS compliance make it a strong fit for council-led retrofit programmes.
