How can I tell what content has changed in this version?

The changes to the content for this year are as follows:

 Major changes:

  • Chapter 1.2 'A consistent approach to finishes' has been updated to reflect NHBC's philosophy of continually improving Standards. First published in 1999 and revised in 2003 and 2006, this latest version builds on previous editions and also ventures into new areas such as ;- wall and floor tiling, sockets and switches, sealant and external works including decks, terraces and balconies.
  • Chapter 6.9 'Curtain walling and cladding' has been updated with some important changes to the definitions of primary and secondary components and their durability. Where secondary components cannot be readily replaced they will have to meet the requirements for primary components.


Minor changes:

  • Chapter 6.1 'External masonry walls'' has been updated to include references to cast stone products.

  • Chapter 9.2 'Drives, paths, and landscaping' has been amended to reflect requirements for timber decking more than 600mm high with reference made to the Timber Decking Association.

All minor changes are identified by a red vertical marker adjacent to the relevant paragraph and the revised text underlined in red. 

  • The CD version of the Standards contains an electronic calculator to determine foundation depths when building near trees. The Chapter 4.2 electronic calculator replaces the old slide rule and is quicker and easier to use. The calculator can also determine the most onerous tree and give guidance on heave precautions.

Can I print out the Standards?

At the top of each page you will find a ‘Print this page’ link which will enable you to print out individual sections.
