What is National Highways Sector Scheme (NHSS) certification?

National Highways Sector Schemes (NHSS) are based on ISO 9001 with additional requirements for highways activities. Developed in conjunction with all parts of the highways industry and the United Kingdom Accredited Service, they were designed to provide an industry benchmark and to give assurance to clients that standards were being consistently applied.

The various Schemes are managed by separate technical advisory committees which comprise representatives from across the industry, certification and training bodies, clients, contractors, suppliers and trade associations.

The Sector Scheme Documents are published by UKAS (United Kingdom Accreditation Service) on behalf of the technical advisory committees and can be downloaded from www.ukas.com
