Fresh air throughout your home without losing heat. We install MVHR systems that recover heat from extracted air, helping keep your home ventilated and energy efficient all year.
MVHR — Mechanical Ventilation with Heat Recovery — is a whole-house ventilation system that simultaneously extracts stale air from wet rooms and supplies fresh filtered air to living areas. As the two air streams pass through the heat exchanger in the central unit, up to 90% of the warmth from the outgoing stale air is transferred to the incoming fresh air — so you get fresh, filtered air without losing heat.
MVHR is the ventilation strategy of choice for new builds and high-performance homes. It can support the Building Regulations and Approved Document F requirements applicable to the project for controlled ventilation, help reduce condensation and mould risk linked to poor ventilation, and reduce the energy needed to heat incoming fresh air throughout winter.
MVHR is easiest to install during construction, but we also carry out MVHR retrofits in existing properties where access for ductwork is available. We assess the feasibility during the free survey.
Our engineers assess your home and design an MVHR system around your ventilation requirements and the Building Regulations guidance applicable to your project.

Fresh air distribution across open-plan kitchen-diner-living spaces.
A carefully designed and installed system commissioned to the correct airflow rates for your home.
We assess your home and design the duct layout, unit position and airflow rates.
We install the central unit and all supply and extract ductwork throughout the property.
We balance and commission the system to the correct airflow rates for each room.

No. While MVHR is easiest to install during construction, we also carry out retrofits in existing properties where there is suitable access for ductwork — typically through loft spaces or service voids. We assess feasibility during the free survey.
Modern MVHR units recover between 85% and 93% of the heat from extracted air depending on the unit specification. This significantly reduces the energy needed to heat incoming fresh air, particularly during winter months.
At normal operating speeds, MVHR is designed to run in the background without being noticeable. The central unit is typically located in a loft or plant room, and correctly designed ductwork keeps noise in individual rooms to a minimum.
We recommend a filter change every 6–12 months and a full system check annually. This keeps the system running at peak efficiency and maintains the air quality benefits throughout the home.
