National Highways Sector Scheme 18 for the Natural Environment and Landscape, including Ecology for Infrastructure.

The National Highways Sector Scheme 18 (NHSS18) is the customised management system for landscaping and the environment (including ecology) and is a mandatory requirement for all contractors working for Highways England and other infrastructure providers.

NHSS18 reflects requirements embodied in EN IS09001:2015 Quality Management system with specific relevance to Landscape Construction and Maintenance, Arboriculture, Application and Management of Pesticides, Amenity, Ecology and Environmental Management and Countryside Management.

The scheme aims to ensure that Organisations working on roads have a trained and competent workforce. Sector Schemes are designed to provide an industry benchmark, ensuring all processes are planned and demonstrate continually improving standards, promoting confidence in quality management systems by the provision of a robust and transparent system.
