NHBC’s revisions to its Technical Standards are now live. The latest edition of the organisation’s Technical Standards applies to every new home registered with the new homes warranty and insurance provider where the foundations have been laid on or after 1 January 2023.

NHBC said its dedicated Standards team had spent the past year applying its expertise to a thorough review of all its technical content. It has been working with stakeholders across the industry “to ensure the Standards continue to provide trusted support and guidance for builders and developers”.

There have been significant changes and updates to several chapters, including:

  • aligning with British Standards, including BS EN 1992, BS 8666 and BS 8102:2022
  • updates to both concrete upper floor design and timber/joist deflection limits and to the weathertightness of windows, doors and glazing
  • new guidance on the provision of horizontal movement joints on masonry clad buildings and on supporting single leaf garage walls
  • addressing the low carbon agenda by:
    – increasing cavity wall widths due to improving thermal performance standards
    – a focus on renewable and sustainable technologies to reduce carbon footprint and provide alternative heating sources.

NHBC said its Technical Standards would continue to help builders and developers deliver “the highest possible new home standards and support the continuous improvement of the quality of new homes”.

Mark Russell, NHBC’s standards and policy manager, said:

“There have been significant changes to this year’s Standards to ensure they remain both relevant and accurate. We are sure the industry will find them a useful reference point as we all work to build safe, high-quality homes for everyone.”
