MVHR Set to Play a Key Role in Meeting Building Regulations and Tackling Damp and Mould Crisis, Says Elta
Posted by: electime 8th October 2025
With UK building standards become more stringent than ever, and the drive for air tightness and energy efficiency increasing, the UK is entering a critical phase for building compliance and indoor air quality. Mechanical Ventilation with Heat Recovery (MVHR) is emerging as a key partner in balancing airtight homes with healthy living environments.
With upcoming regulatory changes – including Awaab’s Law, which compels landlords to act quickly on damp and mould – the need for effective ventilation systems has become even more critical. Elta has launched its HAVA MVHR range to address ventilation compliance, heat efficiency, and occupant health in one solution. David Millward, Product Manager at Elta Group, speaks on the matter.
“With modern homes being built more and more airtight, the importance of controlled ventilation is becoming a more significant matter than before. Without adequate systems in place, stale air, mould, and condensation can accumulate, jeopardising the health of the building and its occupants.
While still technically compliant in some cases, traditional ventilation methods such as extract fans and trickle vents often fall short when it comes to delivering the level of indoor air quality and energy efficiency now expected, particularly in modern airtight homes.
MVHR systems are already widely adopted in some European countries including Sweden and the Netherlands, where the system is seen as standard in new homes. Their ability to supply new, filtered air while recovering up to 92% of heat from outgoing air positions them as an ideal fit for modern building demands.
To add urgency to the adoption of high performing ventilation systems, Awaab’s Law is set to enforce stricter timeframes for landlords and housing providers in dealing with damp and mould. This places additional responsibility on ventilation to perform reliably and help to prevent these issues.
Elta’s MVHR range has been engineered specifically for UK residential use. Available in six different models, the units accommodate vertical, horizontal, and dual orientation mounting, offering installers flexibility in challenging layouts where space may be limited. Each HAVA unit includes Modbus integration for advanced control and also features heat recovery of up to 92%, supporting compliance with current Part F, Part L, and Part O of the UK building regulations.”
By combining energy efficiency with better indoor air quality, MVHR aligns with the government’s ambitions making it a future-proof investments for the building industry and well as homeowners.
The HAVA MVHR range is now available from Elta and through Elta Trade’s network of wholesalers, with detailed product data and technical support available online. For more information on MVHR, please visit https://www.eltatrade.co.uk/
