National Highways Sector Schemes (NHSS) is a bespoke quality management system, based on ISO 9001, for organizations working on the UK road network. It is essential for any company providing services to the Highways Agency under the Specification for Highways Works (SHW) to be NHSS certified.

Element’s market-leading team of certification experts, BM TRADA, provides NHSS certification for organizations to show they are competent to carry out the required works.

The NHSS scheme falls into four main categories:

  • Fencing, landscaping and vehicle safety restraints
  • Road surfacing and marking
  • Lighting, electronics and corrosion protection
  • Traffic management 

Registration to NHSS is generally considered to be mandatory, or at the very least best practice, for all highways works. Companies sub-contracting work do not have to be registered, but any sub-contractors must be.

Benefits of NHSS certification

NHSS certification is designed to provide an industry benchmark and make certain work is carried out to the highest standards of professionalism, using adequately trained staff, with a strong emphasis on health and safety.

Specifically, NHSS certification will provide the following benefits:

  • Continual improvement, making sure processes are planned, maintained and improved with an appropriately trained and competent workforce.
  • Guarantee for stakeholders, with a robust system and framework in place.
  • Access to new business opportunities through procurement specifications requiring certification as a condition to supply.
  • Improved processes that improve efficiencies and reduce costs.
  • Independent verification from auditors with technical knowledge and experience in the sector.
