Heat Recovery Retrofit Solution

Delivering decarbonisation in Social Housing on the path to Net Zero homes by 2050


We use up to 40% of our energy in buildings, with around half of that being used for heating, cooling and other operational energy. With most of the housing stock that will exist in 2050, already built, it is imperative that we improve the heat loss of the existing stock through deep, energy efficient refurbishment.

Without providing adequate ventilation, one of the risks associated with retrofitting a low energy home ready for Net Zero 2050 ambitions is the increasing airtightness. This creates areas where moisture can condense leading to mould growth, which blights many homes across the UK.

Social housing providers, landlords and property managers recognise the challenges and are looking for solutions to protect their housing stock and their residents.

This is where Vent-Axia is able to provide you with the right ventilation solution to support your journey towards Net Zero and healthier homes.
