Following much anticipation and discussion, the government’s updated Approved Document ADF1 (Ventilation) was published on 15 December 2021 for implementation in mid-June 2022.

It has the potential to profoundly impact the glazing industry and homes across the UK. Since publication, the GGF and FENSA have analysed the Approved Document in depth and there is a section within the guidance that is open to interpretation and specifically the level of background ventilation through trickle vents when replacing windows in a dwelling.

In the document, the requirements vary dependent on certain criteria which may cause confusion or leave the decision very much in the hands of the installation company’s representatives. We are seeking clarification from the DLUHC so we may provide accurate information to our members on properly evaluating the ventilation requirements, so that it is not over or under specified.

Prior to the energy crisis, it was calculated that the introduction of trickle vents as a mandatory requirement would result in an increase of £378 per year to an average household’s energy bills and we have laid out how this change to the regulations will impact on homeowners up and down the country.

Over the past month, the GGF and FENSA have been actively engaged with senior officials at the Department of Levelling Up, Housing & Communities (DLUH&C) to establish the full interpretation of the guidance. It is a hugely important matter and one that we have highlighted the impact of on both consumers and the industry in numerous government meetings.

The DLUH&C have welcomed the GGF and FENSA’s input and feedback and as soon as their final interpretation of the regulations are made known, the GGF will disseminate for the industry.
