Choosing the right ventilation system is essential for maintaining healthy indoor air quality, reducing condensation, and ensuring energy efficiency. Many UK homeowners still rely on standard extractor fans for ventilation, especially in kitchens and bathrooms. However, with modern building standards focusing on airtight construction and energy savings, Mechanical Ventilation with Heat Recovery (MVHR) is becoming the preferred choice.

MVHR and extractor fans serve different purposes, but if you're planning a new build, home renovation, or energy-efficiency upgrade, understanding the differences is key to making the best choice.
This guide will explain how MVHR and extractor fans work, their advantages and disadvantages, and which system is better suited for different types of homes.

Mechanical Ventilation with Heat Recovery (MVHR) is a whole-house system that continuously supplies fresh air while recovering heat from extracted air. It’s designed for modern, airtight homes where ventilation is needed without losing heat.
How MVHR works:
This creates a balanced, energy-efficient indoor climate without the need to open windows.
An extractor fan is a simple ventilation solution that removes stale or moist air from a specific room, typically bathrooms, kitchens, and utility areas.
How extractor fans work:
While extractor fans are effective for targeted ventilation, they do not offer whole-home airflow management like MVHR.
MVHR is best suited for:✔ New builds designed with airtight construction.
✔ Renovated homes with upgraded insulation and sealed windows.
✔ Homes prone to condensation and mould due to poor airflow.
✔ Energy-efficient and eco-conscious households looking to reduce heating costs.
✔ Urban homes exposed to outdoor pollution, as MVHR filters air before it enters.
Extractor fans work well for:✔ Older homes with natural ventilation that don’t require whole-house airflow.
✔ Bathrooms and kitchens in small apartments, where targeted moisture removal is needed.
✔ Budget-conscious homeowners who need basic ventilation but don’t mind heat loss.
MVHR installation costs:
Extractor fan costs:
While extractor fans are cheaper upfront, MVHR provides long-term energy savings.
✔ MVHR units consume minimal electricity and reduce heating bills.
✔ Extractor fans increase heating demand, as they remove warm indoor air.
MVHR offers a full-home ventilation solution that supports energy efficiency, air quality, and comfort. With rising energy costs and stricter UK regulations, more homes are switching from basic extractor fans to MVHR for long-term benefits.
✔ Reduces energy waste.
✔ Provides balanced fresh air circulation.
✔ Lowers heating bills while maintaining indoor comfort.
✔ Eliminates condensation and damp for a healthier home environment.
✔ Specialists in whole-home MVHR systems for new builds and renovations.
✔ Fully compliant with Building Regulations Part F and Part L.
✔ Certified engineers with years of industry experience.
✔ Quiet, energy-efficient systems tailored to your home’s needs.
✔ Comprehensive aftercare and servicing options.
