With buildings contributing about 40% of UK greenhouse gases, improving energy performance is crucial for reducing emissions and energy costs.\u003Cbr>\u003Cbr>\u003Cspan style=\"font-weight: bold;\">Key Updates to Part L Regulations!\u003C\u002Fspan>\u003Cbr>\u003Cbr>In June 2022, significant updates were made to Part L regulations to support the government’s net-zero target. The new rules emphasise a fabric-first approach and renewable technologies like heat pumps, aiming to reduce the carbon output of new homes by 31%. Standards for extensions and replacements in existing homes have also tightened.\u003Cbr>\u003Cbr>To be exempt from these new requirements, projects adhering to the 2013 version of Approved Document L2A must have started on-site by 15 June 2023. These changes set the stage for the Future Homes Standard (FHS), which, starting in 2025, will require new homes to produce 75-80% fewer carbon emissions than those built to the previous standard.\u003Cbr>\u003Cbr>\u003Cspan style=\"font-weight: bold;\">Consolidation of Part L Documents\u003C\u002Fspan>\u003Cbr>\u003Cbr>\u003Cspan style=\"font-weight: bold;\">The updated Part L now consolidates into two documents:\u003C\u002Fspan>\u003Cbr>- Approved Document L1 (ADL1): For new and existing domestic buildings\u003Cbr>- Approved Document L2 (ADL2): For new and existing non-domestic buildings\u003Cbr>\u003Cbr>These changes emphasise the importance of both fabric performance and low-carbon technologies in achieving energy-efficient homes.\u003Cbr>\u003Cbr>\u003Cspan style=\"font-weight: bold;\">Energy Performance Standards\u003C\u002Fspan>\u003Cbr>\u003Cbr>The new standards, effective from 15 June 2022, set out detailed requirements for elements like floors, walls, and roofs, with a focus on improved insulation and reduced U-values. These standards are a precursor to the even stricter requirements anticipated under the Future Homes Standard in 2025.\u003Cbr>\u003Cbr>For detailed energy performance standards, refer to the downloadable Part L regulations sheet \u003Ca href=\"https:\u002F\u002Fatspace-ltd.s3.eu-west-2.amazonaws.com\u002Fuploads\u002Fpdfs\u002Fatspace-essential-guide-new-regulations-u-value-handbookpdf.pdf\" target=\"_blank\" rel=\"noopener\">\u003Cspan style=\"color: #76be43;\">HERE!\u003C\u002Fspan>\u003C\u002Fa>\u003Cbr>\u003Cbr>\u003Cspan style=\"font-weight: bold;\">Interim Changes in Wales and Scotland\u003C\u002Fspan>\u003Cbr>\u003Cbr>\u003Cspan style=\"font-weight: bold;\">Wales: \u003C\u002Fspan>New amendments now require newly constructed buildings to follow the SAP 10 methodology and meet a minimum energy efficiency standard, aiming for an EPC rating of B or 81.
