MVHR ventilation for airtight homes
We install ProAir mechanical ventilation with heat recovery (MVHR) systems that continuously bring filtered outdoor air into living spaces while extracting stale, damp air from kitchens and bathrooms. Heat from the outgoing air is transferred to the incoming air, helping an airtight home stay ventilated without wasting as much warmth.
How MVHR improves your home
Continuous filtered fresh air
Fresh outdoor air passes through filters before it is supplied to bedrooms and living spaces.
Helps control condensation
Stale, moisture-laden air is extracted from kitchens, bathrooms and utility rooms before it can settle on cold surfaces.
Recovers heat from outgoing air
Heat from the extracted air is transferred to the incoming fresh air, reducing the amount of warmth lost through ventilation.
Why airtight homes need MVHR
Modern building standards make homes warmer to run, but a well-sealed house needs a proper way to breathe.
Condensation and mould
An airtight home traps moisture from cooking, showers and everyday living. Without somewhere for it to go, it condenses on cold surfaces and windows, and mould can follow. MVHR removes that moist air continuously, before it becomes a problem.
Building regulations
Current building regulations require a background ventilation strategy in airtight new builds. MVHR is the mechanical route: it meets the requirement while recovering the heat that trickle vents simply lose.
What MVHR does for your home
Lower heating demand
Heat recovery reuses warmth from extracted air and can reduce heating demand by 15-20%, depending on the home and system design.

Questions about MVHR.
Plain answers to the things people ask us most. If yours is not here, just call or send an enquiry.
MVHR stands for Mechanical Ventilation with Heat Recovery. It continuously brings fresh, filtered air into your home and extracts stale, moist air, recovering the heat from the outgoing air to warm the incoming air.
If your home is well-insulated and airtight, yes. Airtight construction holds heat well but also holds onto moisture and stale air. MVHR gives it a proper, mechanical way to breathe, and current building regulations require a background ventilation strategy in airtight new builds.
The unit itself uses a small amount of electricity to run continuously. Because it recovers heat from the outgoing air, homes typically see lower heating bills than with trickle-vent ventilation alone. We give you the full running-cost picture during your free home assessment.
MVHR units have filters that need checking and cleaning to keep the system running efficiently, and we talk you through the routine when we hand over your system.
It is most straightforward in a new build or a deep retrofit, since the ductwork needs to reach every room. We assess your home during the free assessment and tell you straight whether it is a good fit.
