AirEx: A new approved measure under ECO4
Unlock funding, unlock opportunity
AirEx is now approved under ECO4. It gives installers a new way to boost EPC scores, cut heating bills and access funding for many homes.
Our smart air brick, the AirEx Floorvent, is made for suspended timber floors, reducing heat loss and draughts..
AirEx typically delivers:
2–4 SAP points
12% average heating bill savings
Installs take around an hour and are easy to fit around other work on homes. It’s low-disruption for residents and high-impact for SAP scores, ideal for ECO-funded retrofits.
ECO4 is a government energy efficiency scheme that helps reduce carbon emissions and tackle fuel poverty. It runs until March 2026 and is funded by energy suppliers.
ECO4 focuses on improving the least efficient homes. Only properties in SAP bands D to G qualify. The scheme supports a whole-house approach, funding multiple energy-saving measures — including insulation, ventilation and heating upgrades. AirEx is now an approved measure under ECO4.
