Leading ventilation manufacturer Vent-Axia is to host a webinar, ‘Domestic Retrofit Legislation and Guidance for Ventilation’, on the recently launched Building Regulations. Aimed at electricians, contractors, installers and electrical wholesalers, the webinar will update delegates on the recent changes to the legislation that they need to know and explain how these changes will affect ventilation in domestic retrofit, especially when adding energy efficiency measures to existing homes.

The Building Regulations were published on 15 December 2021, with the new amended Part L (Conservation of Fuel and Power) set to help the UK deliver Net Zero with a reduction of almost a third less carbon for new build homes. However, as buildings become more air tight to improve efficiency, in both new build and domestic retrofit, it is crucial to consider indoor air quality (IAQ) too to protect the wellbeing of inhabitants. The new Part F (Means of Ventilation) therefore sets out key changes, which will drive uptake of low carbon ventilation as an industry standard and improve the quality of the air we breathe.

This essential webinar ‘Domestic Retrofit Legislation and Guidance for Ventilation’ will be an hour long and will take place on the following date:

  • Thursday 26 May 2022 at 12 noon.

Vent-Axia’s Product Manager, Natasha King and the company’s Technical Product Manager, David Cook will present the webinar. The webinar will explain the important changes to the legislation covering both Part L and F of the Building Regulations, with a particular detailed focus on Part F and the addition of a new sub section ‘Installing Energy Efficiency Measures’. Other topics it will include are: why we need to ventilate; an explanation of the ventilation solutions available for retrofit homes; design considerations such as noise and ingress of pollutants; as well as installation and commissioning; and PAS 2035. There will also be the option to ask questions at the end. To sign up visit:

We welcome the new Building Regulations as they are set to improve indoor air quality in existing homes. One of the biggest changes in the Regulations for electricians and contractors is the requirement to consider ventilation when adding energy efficiency measures to existing properties. Previously, when the airtightness of buildings was increased to improve energy efficiency many homes suffered from condensation, mould and poor IAQ because ventilation was not considered”, said Natasha King, Product Manager at Vent-Axia. “At Vent-Axia we are keen to help electricians and contractors to comply with the Regulations by explaining the changes and how to meet them with our webinar offering the ideal opportunity to find out about the new legislation and to ask questions on how this might affect ventilation in retrofit projects.”

For electricians, contractors, installers and electrical wholesalers a key addition to Part F, which shows the significance of ventilation in meeting Net Zero, is a new sub section ‘Installing Energy Efficiency Measures’, which relates to existing properties. “When carrying out energy efficiency measures to an existing dwelling, an assessment should determine what, if any, additional ventilation provision is needed, based on the estimated impact of the work.” This is a welcome addition to the Regulations since previously many homes have suffered from condensation, mould and poor indoor air quality following energy efficiency measures, which have increased the airtightness of the building envelope to reduce carbon emissions. This positive move will help protect the health and wellbeing of inhabitants from indoor air pollution and protect buildings from damp, condensation and mould caused by moisture not being able to escape.

For existing homes, Vent-Axia has a wide range of extractor fans available to help provide effective ventilation and comply with Part F. For example, the Lo-Carbon Svara combines condensation control to avoid mould with improved IAQ for a healthier home environment backed up by easy installation, quiet operation and is controllable via a smartphone. Meanwhile, Vent-Axia’s Silent Fan range boasts seventeen models and a raft of new features, including IPX5-rating (for Zone 1) making installation easier and safer. The range also offers both humidity and variable speed models and is still the quietest bathroom fan available at just 12dB(A). The Vent-Axia PureAir Sense is the UK’s only bathroom fan with Odour Sense technology that increases airflow when the air quality is poor, helping ensure a comfortable living environment.
