Energy Efficiency and Indoor Air Quality: How Modern Ventilation Saves You Money

In the past, getting rid of stuffy or damp air often meant opening windows—letting out expensive heated air and letting in the cold. While this approach solves short-term issues, it drives up heating bills and reduces comfort, especially during winter. For many UK homes, up to 20% of heat loss can be attributed to uncontrolled ventilation.

Today's systems deliver both energy performance and air quality thanks to innovative engineering:

MVHR (Mechanical Ventilation with Heat Recovery)

How it Works: Fresh air is continuously supplied to your living spaces, while stale, humid air is extracted from wet rooms. Crucially, the outgoing air passes through a heat exchanger, capturing up to 95% of its warmth to pre-heat the incoming air. The result? A constant supply of fresh air—without extra heating costs or draughts.

Benefits:

• Considerably lower heating bills
• Consistent air temperature throughout the house
• Ideal for airtight modern homes and energy-efficient retrofits

Trickle Vents, PIV, and MEV

Positive Input Ventilation (PIV): Low-energy fans gently introduce filtered air into the home, pushing out pollutants and helping control humidity—with electricity bills typically under £10 a year for most properties.

Mechanical Extract Ventilation (MEV): Continuous, efficient extraction from key rooms using energy-saving, low-wattage units.

It's not just about saving money—you're also investing in your family's wellbeing:

• Pollutant Reduction: Removes VOCs from paints, cooking gases, and cleaning products.
• Pollen and Allergen Filtration: MVHR and PIV systems with high-grade filters reduce seasonal allergies.
• Better Sleep and Concentration: Stale, stuffy air has been linked to poor quality sleep and decreased productivity.
• Property Value: Homes with advanced ventilation and proven indoor air quality standards are increasingly popular for buyers and renters.

Modern ventilation systems are designed to keep you ahead of regulation—meeting and exceeding requirements like Part F and the new Awaab's Law. With the focus on damp, mould, and healthy environments, future-proofing your home now avoids expensive compliance upgrades and health risks later.

Our team will:

• Assess your unique requirements and propose solutions that optimize airflow and energy use.
• Specify and install best-in-class MVHR, PIV, or MEV systems for your home's layout and performance goals.
