Learn more about NHSS Certification

NHSSs (National Highway Sector Schemes) are integrated quality management schemes, bespoke to individual highways specialisms. They aim to make sure that work is carried out to the highest standards of professionalism, using properly trained and competent staff.

NHSSs are primarily designed as complementary standards to ISO 9001 for organisations working on the UK’s road network. They’re based on the current ISO 9001:2015 framework and provide specific requirements and interpretation for maintenance and construction, inspection and interrelated activities.

There are more than 20 individual schemes.

NHSS schemes come under eight main categories:

  • Highway assets including design
  • Fencing including vehicle safety restraints
  • Electrical and land drilling
  • Road surfaces, surface marking and paving
  • Manufacturing, structures, fasteners and coatings including stockholding
  • Temporary traffic management
  • Landscaping and natural environment (including ecology)
  • Tunnel management, incident management including vehicle recovery
