MVHR (Mechanical Ventilation with Heat Recovery) provides fresh, filtered air while recovering heat from outgoing stale air, improving indoor air quality and energy efficiency.
It extracts stale air from kitchens and bathrooms, recovers heat, and supplies fresh, pre-warmed air into living spaces.
Yes, but retrofitting may require space for ductwork. Older homes may need compact or decentralised MVHR units.
No—if installed correctly. Poor ducting or incorrect fan speeds can cause noise. Use acoustic ducting and balanced airflow to keep it quiet.
No. MVHR reduces heat loss, but it does not generate heat. You still need a heating system in cold weather.
Property Type Estimated Cost Range
Flats & Small Homes (1–2 beds) £3,500 – £5,000
Medium Homes (3–4 beds) £5,000 – £8,000
Large Homes (5+ beds) £8,000 – £12,000
New Build Installations £4,500 – £7,500
Retrofitting in Existing Homes £6,000 – £12,000
Yes. Filters remove pollen, dust, and pollutants, improving air quality for allergy sufferers.
No. MVHR replaces the need for trickle vents and extractor fans, as it provides continuous ventilation.
Yes. By continuously ventilating and controlling humidity, MVHR prevents moisture buildup that causes mould growth.
Basic tasks (filter replacement, minor ductwork) can be DIY, but full installation requires a professional to ensure:
Ideally in a loft, utility room, or cupboard—away from bedrooms and living spaces for minimal noise.
It should run continuously for optimal air quality, but some systems allow speed adjustments based on occupancy.
Yes! MVHR + heat pumps = maximum energy efficiency, reducing heating demand and improving air quality.
Absolutely. While the upfront cost is high, MVHR reduces heating bills, improves air quality, and prevents long-term damp issues, making it a smart choice for energy-efficient homes.
