The National House Building Council, a provider of warranty and insurance, has launched the 2020 edition of its technical standards.
The new standards affect foundations that begin on or after 1 January.
The organisation that provides warranties for most of the new homes in Britain is paying millions of pounds to the leading housebuilders every year, raising questions about its independence and credibility amid a wave of complaints about the quality of new-build properties.
NHBC, the standard-setting body and main home construction warranty provider for new builds in the UK, is paying around £10m to £15m every year to housebuilders through what is effectively a profit-share agreement. The largest firms can receive as much as £2m from the scheme, because it rewards the developers who registered the most homes with NHBC.
Mechanical ventilation and heat recovery systems in ten new homes that were especially monitored over 18 months were so badly designed or installed that nine had to be re-commissioned and one replaced.
