MVHR System Cost: What You Need to Know Before Installing

If you’re thinking about upgrading your home’s ventilation or building a low-energy house, understanding the MVHR system cost is essential. Mechanical Ventilation with Heat Recovery (MVHR) systems are becoming more popular for homeowners who want to improve air quality while reducing energy bills—but how much do they actually cost?

In this guide, we’ll explore everything you need to know about an MVHR system, from system prices and installation to running and maintenance expenses.

What Is the Average MVHR Cost?

The MVHR cost can vary depending on the type of system you choose and the size of your property.

• A standard MVHR system for an average four-bedroom new-build typically costs around £3,500.

• If you’re aiming for Passivhaus standards, which demand high energy efficiency, the MVHR cost rises to around £7,000.

• High-spec MVHR systems with features like active cooling and room-by-room controls can push the MVHR cost beyond £13,500.

MVHR System  Installation: Professional vs DIY

On top of the equipment itself, the MVHR system cost includes installation—unless you’re planning a DIY project.

• Professional installation usually adds £1,000 to £4,000 to the total MVHR system cost, depending on how complex your home layout is.

• If you’re experienced with DIY projects, you could lower your overall MVHR system by doing the installation yourself. However, commissioning still needs to be done by a certified professional, and a qualified electrician is required to check the electrical connections.

Retrofitting and MVHR Cost

Retrofitting an MVHR system into an existing home often increases the total system cost because of the extra work needed to fit ducting into walls, ceilings, or floors.

Some retrofits might require you to vacate the property temporarily—another potential addition to your cost. If your home isn’t suitable for a central duct system, decentralised MVHR units may offer a lower-cost, less disruptive option.

Running Costs and Maintenance

After installation, the MVHR cost continues in the form of running and maintenance expenses—but the good news is, these are fairly low.

• Most MVHR systems use about 300kWh per year, which equals roughly £150–£160 annually on your energy bill.

• Maintenance is straightforward: replace filters every 6–12 months. Filter costs can range from £20 to £120, depending on the model—adding a small but important component to your overall MVHR system cost.

Cutting Your System Cost: Smart Tips

Want to reduce your MVHR system cost without cutting corners? Here are a few ideas:

• DIY installation (with a professionally designed plan) can slash your installation costs.

• Plan early if you’re building a new home—designing the system into the build saves both money and time.

• Decentralised MVHR units can reduce the MVHR system cost for renovation projects.

Is A MVHR System Worth It?

While the initial MVHR cost might seem high, the long-term benefits—better air quality, energy savings, and a more comfortable home—often outweigh the expense. Especially in well-insulated homes, MVHR systems play a vital role in maintaining fresh air without losing heat.

If you’re serious about building or renovating for efficiency, factoring in the system cost early could save you a lot of stress and money down the line.
