Part L (England & Wales), Section 6 (Scotland) and Part F (Northern Ireland) are all about to change. As part of meeting their climate change targets, the four nations have been consulting on revisions to energy efficiency regulations and the coming years will bring some major changes. The first round of those changes is now imminent, with publication and implementation of new regulations within the coming year. The 2022 uplift will see significant reductions to Target CO2 Emission Rates alongside the introduction of new targets and more challenging standards for individual elements (walls, floors windows, etc).
