Since the launch of the CLOCS Standard in December 2013, the construction industry has taken ownership of work related road risk beyond legal requirements. A wide range of construction clients, principal contractors and fleet operators have openly committed to implement and adhere to the requirements of the CLOCS Standard by signing a Memorandum of Understanding

A supply chain comprised of CLOCS Champions means that clients, contractors and the vehicle operators are working together to minimise risk to vulnerable road users.

A list of organisations committing to take responsibility for safety beyond the site gate can be found in the Champions Directory.


The CLOCS Standard

The CLOCS Standard is a national industry standard that promotes good practice beyond basic legal compliance. It defines the primary requirements placed upon the key stakeholders associated with a construction project and places responsibilities and duties on the regulator, the client, the principal contractor controlling the construction site and the supply chain including the operator of any road-going vehicles servicing that project.


What is a CLOCS Champion?       

A CLOCS Champion is an organisation committed to actively promoting and implementing the national CLOCS Standard.  See the Champions Directory to find out who else is involved.

CLOCS Champions can be planners/regulators, clients/developers, principal contractors, sub-contractors bringing vehicles to site, fleet operators & vehicle manufacturers & suppliers, and communicators...who are you?


The CLOCS working group

The CLOCS working group represents a balanced mix of industry representatives that are in a position to influence positive change.  It is responsible for keeping the CLOCS Standard current and effective and for recommending and overseeing the production of supplementary guidance and tools to support implementation.

The CLOCS team/secretariat

The CLOCS team is responsible for implementation of the Standard and promoting industry awareness. Their role is also to support CLOCS champions to achieve the goals of their implementation plans.  An on-going programme includes the production of tools and supplementary guidance on a range of topics, including procurement, compliance monitoring and collision reporting.

SECBE leads the CLOCS team and, alongside the primary task of upholding and developing the Standard to maintain its fitness for purpose, our aim is to grow adoption of the CLOCS Standard across the UK. Our experience and success with engaging and supporting leaders in construction to improve performance, adopt new processes and win more work makes us the perfect partner to ensure a road safety culture and a common standard are embedded right through the supply chain.

The Construction Clients’ Leadership Group (CCLG) represents public and private sector clients to promote best practice and industry improvements.  Clients adopting the CLOCS Standard take ownership of road safety in supply chains and can promote a culture of safeguarding vulnerable road users through their procurement strategy.

LHC provides public sector organisations with the best procurement solutions for the construction, refurbishment and maintenance of social housing, schools and public buildings. Working with LHC frameworks is helping to embed CLOCS into public sector projects.

Build UK’s ‘Don’t break the Chain’ campaign is encouraging the supply chain to adopt the CLOCS Standard to reduce risk to vulnerable road users.  As a strong collective voice for the construction supply chain, Build UK provides influential and dynamic leadership for the support of CLOCS.  The adoption of recognised standards enhances performance, facilitates a more efficient use of resources, and allows the industry to focus on eliminating, reducing and managing risks at all stages of a project.

The Considerate Constructors Scheme (CCS) monitors around 8,000 construction sites, companies and suppliers every year.  CLOCS has partnered with CCS to harness their valuable network of ‘men on the ground’ to deliver CLOCS Site Monitoring Visits for CLOCS Champions. The Scheme has recognised CLOCS as an important standard; with the protection of vulnerable road users being part of the Scheme’s monitoring checklist for a number of years.

Development of CLOCS and the national Standard was sponsored by Transport for London in response to research that showed that construction vehicles were responsible for a disproportionately high number of cyclist and pedestrian fatalities involving HGVs in London.  The CLOCS Standard calls for the construction industry to recognise its responsibilities for vehicles and drivers delivering to, and collecting from, construction sites. Transport for London (TfL) made good progress in working with industry to embed the CLOCS Standard across London and the UK and has been particularly successful in its work with vehicle manufacturers to improve vehicle safety.


FORS and CLOCS work together, to keep compliance simple. If you work in the construction industry and operate vehicles, FORS Silver accreditation will ensure you are CLOCS compliant.
