Part L 2021 is introducing a big change to the notional specification, which may seem daunting. But the notional specification has changed every time that Part L has changed, so the question is how best to adapt. At the moment, we know the fundamentals of what is being proposed for new dwellings and we’ll guide you through what’s changing to understand the impact.
If you’re not already thinking about how to achieve net zero, then Part L 2021 is a starting point. So far, only the consultation response on dwellings has been published. Existing dwellings, non-residential buildings and regulations on overheating will follow. We’ll look at how you can start planning and managing risk.
Preparing for Part L 2021: Government response
So far, the government has consulted on and responded to the proposed Part L 2021 as it relates to new dwellings. A separate consultation dealing with existing dwellings, non-domestic buildings and regulations for overheating is currently in progress.
When the government has published its response to that consultation, a ‘full’ Part L 2021 will be published at the end of this year, alongside a new Part F and Overheating Regulations. They will all come into effect from June 2022.
This rapid progression of new standards could cause issues, especially on larger sites. If a Part L 2013 building notice or full plans have been submitted by June 2022, the proposed transitional arrangements mean that work will have to start by June 2023.
A significant change to transitional arrangements is that they will apply on a dwelling-by-dwelling basis, rather than to the site as a whole. Any dwellings where work has not started would then need to be constructed to Part L 2021 regulations. Developers might seek to get round this by doing the minimum amount of work, like excavation for foundations, for each plot on the site rather than a single plot. That won’t always be practical, however.
