What You Will Learn

This 45-minute course covers:

• UK Building Regulations and how they apply to residential ventilation
• Recent changes to Building Regulations relating to ventilation requirements
• The features and benefits of using mechanical ventilation with heat recovery in residential buildings
• How MVHR systems meet regulatory requirements for indoor air quality and energy efficiency
• Good practice examples of residential MVHR installations
• Common installation challenges and how to overcome them

Who Should Take This Course?

This course is suitable for heating and plumbing engineers installing MVHR systems in residential properties, building services designers and consultants specifying ventilation for new builds or refurbishments, architects and specifiers looking to incorporate compliant MVHR systems, installers and contractors planning residential MVHR installations, and anyone involved in the design, specification, or installation of ventilation systems in residential buildings.

Why Building Regulations Knowledge Matters

UK Building Regulations set minimum standards for ventilation in residential buildings to ensure adequate indoor air quality and prevent issues such as condensation, damp, and mould. Recent changes have placed greater emphasis on energy-efficient ventilation solutions, making MVHR an increasingly popular choice for new builds and refurbishments.

Understanding the regulatory requirements, how MVHR systems meet those requirements, and good practice installation guidance is essential for anyone involved in residential ventilation projects.

Frequently Asked Questions

What is Mechanical Ventilation with Heat Recovery (MVHR)?
MVHR is a ventilation system that supplies fresh air to a building while extracting stale air from inside. The system recovers heat from the outgoing air and transfers it to the incoming air, helping maintain comfortable indoor temperatures while reducing energy loss.

Why is ventilation important in residential buildings?
Proper ventilation helps remove moisture, pollutants, and stale air from homes while supplying fresh outdoor air. This reduces the risk of condensation, mould growth, and poor indoor air quality, helping create a healthier living environment.

Which UK Building Regulations apply to residential ventilation?
Ventilation requirements in residential buildings are mainly covered by Building Regulations Part F, which sets minimum standards for airflow and indoor air quality. Energy efficiency considerations are also influenced by Part L, which encourages the use of energy-efficient ventilation systems such as MVHR.

Why is MVHR becoming more common in new homes?
Modern homes are built to be more airtight to improve energy efficiency. MVHR systems provide controlled ventilation in these airtight buildings while recovering heat from extracted air, helping maintain indoor air quality without wasting energy.

Can MVHR systems be installed in existing homes?
Yes, MVHR systems can be installed in existing properties, particularly during major refurbishments. However, installation may require careful planning to accommodate ductwork and ensure the building is sufficiently airtight for the system to operate efficiently.

What are common installation challenges with residential MVHR?
Common challenges include incorrect duct sizing, poor system balancing, inadequate insulation of ductwork, and insufficient space for installation. Following good practice guidance helps ensure the system performs efficiently and quietly.

Who should take this course?
This course is suitable for heating engineers, installers, building services designers, architects, and contractors involved in residential ventilation systems. It is also useful for anyone who needs to understand how MVHR systems meet UK regulatory requirements.

Will I receive a CPD certificate after completing the course?
Yes. After completing the course and the knowledge check questions, you will be able to download a CIBSE-accredited CPD certificate confirming your participation.
