Our MVHR installation process

We manage the entire MVHR project, including design, installation and ongoing servicing, with one experienced team overseeing every stage.

1. Survey & design

Our engineers assess your property and create a detailed plan for MVHR ducting, MVHR vents, and airflows.

2. System supply & preparation

We’ll visit your property to assess the site and plan the installation. Once the details are confirmed, we’ll supply the complete MVHR kit, including the unit, ductwork, filters and smart controls.

3. Professional MVHR installation

Certified MVHR installers fit your MVHR system neatly and safely, ensuring it meets all regulations.

4. Testing, commissioning & servicing

Before handover, we balance and test the airflow, explain maintenance, and offer ongoing MVHR service options.

Frequently asked questions

Can I install an MVHR unit myself?

DIY MVHR kits are available, but successful installation involves more than fitting the unit and ductwork. The system must be designed to provide the correct airflow in each room, then properly balanced and commissioned.

Professional installation helps ensure the system operates quietly and effectively and is installed in line with relevant Building Regulations and ventilation requirements.

How much does MVHR cost?

MVHR installation costs depend on your property size, ducting design, and chosen system type. A single room MVHR will cost less than a full-house or commercial MVHR setup, but all offer long-term savings through MVHR heat recovery.

‍

Is an MVHR system noisy?

A properly designed and commissioned MVHR system should run quietly. Problems with noise are usually linked to poor system design, such as an incorrectly sized unit, unsuitable positioning or poorly planned ductwork.

SGS Energy designs each system around the property and carefully balances the airflow during commissioning to help ensure quiet, consistent performance.

‍

What does MVHR stand for?

MVHR stands for Mechanical Ventilation with Heat Recovery.

It's a ventilation system that extracts warm, stale air from rooms such as kitchens and bathrooms, recovers much of the heat, and uses it to warm fresh air supplied to living rooms and bedrooms.

The result is a steady supply of fresh air with less heat loss than opening windows or using standard extractor fans.

‍

What is an MVHR system?

An MVHR system is a whole-house ventilation system that continuously removes stale, humid air from rooms such as kitchens and bathrooms, while supplying fresh, filtered air to bedrooms and living spaces.

As the outgoing and incoming air pass through the unit, heat from the stale air is transferred to the fresh air without the two air streams mixing. This helps maintain a steady flow of fresh air while reducing the amount of heat lost through ventilation.

MVHR systems are particularly well suited to modern, well-insulated and airtight homes. They can help reduce condensation, manage moisture, improve indoor air quality and make the home easier to heat efficiently throughout the year.

‍

What is a heat recovery fan?

A heat recovery fan is part of a ventilation system that removes warm, stale air from inside a property and uses its heat to warm the fresh air coming in.

Unlike a standard extractor fan, it helps retain heat that would otherwise be lost through ventilation. This can improve indoor air quality, reduce condensation and lower the amount of energy needed to heat the building.

Heat recovery fans are commonly used in bathrooms, kitchens and utility rooms, either as single-room units or as part of a whole-house MVHR system.
