Mechanical Ventilation and Heat Recovery
Improve indoor air quality, cut heating costs, and enjoy year-round comfort with expertly designed and installed mechanical ventilation and heat recovery (MVHR) systems.
Mechanical Ventilation and Heat Recovery Specialists
Our Mechanical Ventilation and Heat Recovery (MVHR) services provide a proven solution for homes and commercial buildings, delivering fresh, filtered air while recovering heat that would otherwise be lost.
We design, install, maintain, and repair MVHR systems tailored to your property, ensuring optimal performance, comfort, and long‑term energy savings.
What Is Mechanical Ventilation and Heat Recovery (MVHR)?
Mechanical Ventilation and Heat Recovery (MVHR) is a whole‑building ventilation system that continuously extracts stale, moist air from kitchens, bathrooms, and utility rooms while supplying fresh air to living and sleeping areas. A high‑efficiency heat exchanger transfers heat from the outgoing air to the incoming air, reducing heat loss and improving energy efficiency with many benefits including:
- Consistent supply of fresh, clean air
- Reduced heat loss and lower energy bills
- Improved indoor air quality
- Reduced condensation and mould growth
- Enhanced comfort all year round

Frequently Asked Questions
Choosing the right mechanical ventilation and heat recovery system can raise a few questions. We’ve answered the most common queries below to help you understand how MVHR works and whether it’s right for your property.
Yes. While MVHR is ideal for new builds and airtight properties, it can also be retrofitted to existing homes with the right design.
Filters should typically be checked every 3–6 months and replaced annually. Full servicing is recommended at least once a year.
MVHR systems use electricity to run fans, but the heat recovered usually outweighs the running costs, resulting in net energy savings.
A mechanical ventilation and heat recovery (MVHR) system works by extracting warm, stale air from moisture-producing rooms and using a heat exchanger to transfer that heat to fresh incoming air. This process provides continuous ventilation while significantly reducing heat loss and improving energy efficiency.
MVHR systems are very energy efficient and typically have low running costs. While they use electricity to operate the fans, the heat recovered from extracted air often results in overall heating cost savings, especially in well-insulated and airtight buildings.
In many new-build and airtight properties, mechanical ventilation and heat recovery systems help meet current building regulations by ensuring adequate ventilation and energy efficiency. MVHR is commonly used to comply with ventilation and indoor air quality requirements.
Yes. MVHR systems improve indoor air quality by continuously filtering incoming air and removing dust, pollen, and airborne pollutants. This can help reduce allergy symptoms and create a healthier indoor environment for occupants with asthma or respiratory sensitivities.
A well-designed and properly maintained MVHR system can last 15–25 years. Regular servicing, filter changes, and professional maintenance are key to maximising lifespan and maintaining efficient performance.
Yes. Mechanical ventilation and heat recovery systems are designed to operate efficiently all year round. In colder months, they recover heat to reduce heating demand, while in warmer months they help manage fresh airflow without excessive heat gain.
Standard mechanical ventilation extracts stale air but does not recover heat, leading to higher heat loss. Mechanical ventilation and heat recovery systems, however, reuse heat from extracted air, making them far more energy efficient and cost-effective in the long term.
