A Year On: Progress on Part L, F & O

Architects’ Datafile has launched a new white paper, revisiting the updated Building Regulations Parts L, F and O.

In February 2023 we surveyed architects on their knowledge and approach to the updated Building Regulations Parts L, F and O (the latter being the new standard on overheating in new dwellings). The results gave pointers as to the industry’s readiness to tackle the Future Buildings Standard (FBS) and Future Homes Standard (FHS), due to be implemented in 2025, which the Regs updates provide a stepping stone towards.

As well as looking at our readers’ views on the changes for specification, such as building fabric, we established which solutions architects were specifying to meet the new Regs on their projects. A year on from the original study, we again canvassed readers on their experience, to find out how the standards are functioning and what has changed, but also discover remaining issues, and views on the upcoming 2025 FBS/FHS. We tracked progress over the year by reproducing a series of questions from previous study for a direct comparison.

We have also added new questions – in part informed by insights gained at our 2023 industry round table on Parts L, F and O, which raised a series of specific design issues, from glazing area and clients’ expectations, to meeting planning challenges, SAP10, and sourcing performance data on products.
