We believe in evidence-based solutions.

The Airex smart air brick system has undergone a series of robust and independently validated tests and trials that evidence the impact it can have to reduce energy bills.

The largest of these trials was a 115 homes ECO trial (the UK’s first ECO Demonstration Action trial) under the Energy Company Obligation scheme). Over 6 million data points gathered were analysed and independently validated by a team of researchers and building energy specialists (led by Build Test Solutions) using their SmartHTC methodology to measure heat loss.

Based on the trial results, it was concluded that Airex improves the energy efficiency of an average 3-bed, semi-detached, gas-heated UK home by 2-3 SAP (EPC) points. As such, Airex delivers a cost of £150 - £225 per SAP point gained.

These results place Airex as one of the most cost-effective energy efficiency solutions on the market, with a modest payback of as little as 2-3 years.

Independently validated by building energy specialists.
