Smart Air Bricks: Reducing Heat Loss and Improving EPC Ratings
Through AirEx, we’re making homes more energy efficient with the world’s first smart air brick. AirEx Floorvent is a simple, smart solution for suspended floors. It improves SAP scores by approximately 2–4 points, reduces draughts, and helps keep homes warm. By reducing heat loss, it lowers energy bills for residents.

What AirEx?
AirEx Floorvent offers a fast, affordable alternative to more disruptive or expensive measures. It installs easily with no major work required. Built-in sensors and local weather data are used to adjust airflow automatically, reducing heat loss while maintaining effective ventilation. The result is warmer homes, lower carbon emissions, and reduced energy costs.
A Low-Disruption Retrofit That Works
Retrofit upgrades can be disruptive, which can make residents hesitant. AirEx Floorvent is quick to install and non-intrusive. It requires no major works or access to the main living areas. Once installed, it operates automatically, keeping homes warm while preventing damp and condensation.
For housing providers and retrofit coordinators, AirEx delivers an affordable, high-impact solution suitable for a wide range of properties. It is eligible under ECO4, the Warm Homes: Social Housing Fund, and Warm Homes: Local Authority Grant schemes—helping projects stay on schedule and within budget.

Harshit, who conducted the building survey, had worked hard with great patience to find solutions to keep all parties satisfied.
The work started and finished as promised in 3 weeks. They arrived on time every day, and kept working tirelessly till the end. They always laid down protection sheets on floors. There were insulation team, electrical team, and people at the office to coordinate, making sure the project went seamlessly. There were small issues after completing the job, but with communication, the issues were fixed straight away.
I am very impressed with their good team spirit and efficiency. The result of the work is high quality. I have no hesitation to recommend this company to anyone who would like to improve their homes on energy.
