MVHR System Design & Installation Across Hampshire, West Sussex, the South Coast & Cornwall
Fresh, Energy-Efficient Ventilation That Improves Air Quality and Reduces Heat Loss
MMechanical Ventilation with Heat Recovery (MVHR) systems provide a continuous supply of fresh, filtered air while recovering heat that would otherwise be lost from your home. At Evolve Design & Build, we design and install MVHR ventilation systems for homes across Hampshire, West Sussex, the wider South Coast and Cornwall, helping to improve indoor air quality, reduce condensation and lower energy costs.
Our approach focuses on simple, efficient ventilation solutions that create healthier, more comfortable living spaces while supporting sustainable, energy-efficient homes
How Does a Mechanical Ventilation with Heat Recovery (MVHR) System Work?
An MVHR system works by continuously removing stale, moisture-filled air from areas such as kitchens, bathrooms, and utility rooms, while gently supplying fresh, filtered air into living spaces and bedrooms. As the warm air is extracted, its heat is recovered and used to warm the incoming fresh air, helping your home stay comfortable without wasting energy.
This is particularly beneficial for UK homes, where cooler temperatures, high humidity, and well-insulated modern buildings can often lead to condensation and poor air quality. Because the air is constantly refreshed, MVHR systems help reduce mould, damp, and indoor pollutants while maintaining a steady indoor temperature. An MVHR system quietly improves air quality, boosts comfort, and supports lower heating costs throughout the year.
Cost Savings of an MVHR System
MVHR systems help reduce heating costs by recovering warmth from extracted air that would otherwise be lost. This allows fresh air to be supplied without the energy waste that comes from opening windows, particularly during colder months.
By reducing condensation and excess moisture, MVHR can also help prevent damp and mould, lowering the risk of future repair costs. When installed in a well-insulated home, it offers a long-term, energy-efficient way to improve comfort while keeping running costs down.
Regulations & Part F Compliance
MVHR systems must comply with UK Building Regulations Part F for ventilation. After installation, the system must be properly commissioned and certified by a qualified installer, such as a NICEIC registered professional, to ensure it operates safely and efficiently.
MVHR Servicing & Maintenance
Evolve Design & Build also carry out ongoing servicing, maintenance and repairs to existing MVHR and air ventilation systems, helping to ensure they continue to operate efficiently and reliably.
Benefits of
an MVHR System
- Fresh, filtered air for a healthier living environment
- Helps reduce allergens, condensation, and moisture build-up
- Lowers the risk of damp and mould in the home
- Reuses heat that would otherwise be lost, improving efficiency
- Helps reduce heating bills and energy use
- Quiet, low-maintenance system designed for everyday living
Planning Your Ventilation Strategy
A well-designed ventilation system is an essential part of creating a healthy, comfortable home and should be considered as early as possible in the design process. For new builds, planning ventilation alongside other key services such as heating and insulation allows the system to be fully integrated into the overall layout, delivering better performance and long-term efficiency.
In existing homes, a thoughtful ventilation strategy is just as important. MVHR systems can often be designed to work within the current structure, using practical duct routes and minimal disruption where possible. Whether you’re building from scratch or upgrading an existing property, careful planning helps improve air quality, reduce condensation, and create a more energy-efficient home.
FAQs
This is the text area for this paragraph. To change it, simply click and start typing.
Is MVHR suitable for my home?
MVHR works best in well-insulated and airtight homes, including new builds and some renovated properties. A simple assessment can help determine whether it’s suitable for your home.
Will an MVHR system help with condensation and damp?
Yes. MVHR systems continuously remove moisture-laden air, helping to reduce condensation, damp, and mould, which are common issues in UK homes.
Does an MVHR system need much maintenance?
Maintenance is minimal. Filters usually need replacing once or twice a year to keep the system running efficiently and maintain good air quality.
Is MVHR noisy?
When properly designed and installed, MVHR systems operate very quietly. Most homeowners find they’re barely noticeable in day-to-day use.
Can MVHR be installed in an existing home?
In many cases, yes. MVHR can often be retrofitted using carefully planned duct routes, depending on the layout of the property
Still have a question?
