    Air tightness requirements differ for:<\/p>\n

    Residential buildings\u00a0(houses and flats)
    Commercial buildings\u00a0(e.g., care homes, student accommodation, and other non-residential structures)
    In\u00a0June 2022, a revised version of\u00a0Approved Document L\u00a0came into force, divided into:<\/p>\n

    Volume 1:\u00a0Dwellings
    Volume 2:\u00a0Buildings other than dwellings
    This update introduced significant changes to reduce carbon emissions by 31% for new buildings. These changes impact multiple aspects of energy efficiency, including insulation, fuel types, and air tightness, as part of the roadmap to the\u00a0Future Homes Standard\u00a0in 2025.<\/p>\n

  • Mandatory Testing: Every unit must be tested \u2013 no sampling allowed.<\/li>\n
  • Tighter Standards: Maximum air permeability reduced from 10 m\u00b3\u00b7h\u207b\u00b9\u00b7m\u207b\u00b2 @50Pa to 8 m\u00b3\u00b7h\u207b\u00b9\u00b7m\u207b\u00b2 @50Pa.<\/li>\n
  • New Testing Standard: Testing now follows CIBSE TM23 guidelines.<\/li>\n<\/h4>\n

    The\u00a0specific air permeability target\u00a0for each property is based on the design rate outlined in the\u00a0SAP energy calculation. Knowing this figure from the outset is crucial to achieving compliance.<\/h4>\n
