The National Highways Sector Scheme 17 (NHSS 17) is in addition to PAS 43 and specifically addresses the following two areas:
NHSS 17 can only be applied with the integration of ISO 9001 & PAS 43 and not as a standalone certification.
It applies to organisations providing contracted vehicle removal and recovery at highway construction sites where a free recovery service is provided during construction work (NHSS 17A)
Where applicable this includes highway maintenance and construction sites on motorways, high-speed dual carriageways and other roads as required by Highways England, it is not applicable to Wales and Scotland.
It may also be a Police scheme requirement for the preservation of evidence and may therefore be applicable to operators providing SOCO bays and compound facilities for the Police.
