Frequently Asked Questions


You will need to review the terms of the CLOCS Memorandum of Understanding and Terms of Reference. If you agree to accept these terms you will need to register with CLOCS and submit an acceptable CLOCS Implementation Plan online. This Plan will provide a headline statement of your corporate intent to implement and comply with the CLOCS Standard. Once this Plan has been approved you will become a CLOCS Champion and your name will display in the CLOCS Champion Directory.

When organisations have been approved as ‘CLOCS Champions’ an account is created on a dedicated portal. This has been developed enable Champions to manage:

  • Implementation Plans, progress and evidence of compliance
  • Information that is published in the CLOCS Champion Directory
  • Distribution of CLOCS bulletins, alerts and other communications within your organisation.

No. CLOCS compliance can only be established upon attendance at a specific construction site. Vehicle Operators demonstrate compliance through FORS Silver accreditation or FORS Bronze + safety equipment and driver training specified in the CLOCS Standard. Developers and Principal Contractors demonstrate compliance through Site Compliance Monitoring visits. You can find a directory of CLOCS Champions – they are companies where a corporate commitment to work towards CLOCS compliance has been made. These companies understand the CLOCS Standard and can respond positively to procurement requirements.

CLOCS Champions are encouraged to widely promote CLOCS. You can download a copy of the CLOCS logo to embed on your website from your account in the CLOCS Portal. Copies of logos and artwork for posters and hoardings can be provided upon request. Contact

Few CLOCS champions will have 100% CLOCS compliance from the outset but they will all have an action plan for implementation. As planning and procurement increasingly mandate the CLOCS Standard, CLOCS Champions will be able to demonstrate at pre-qualification that they understand what is required to deliver to the CLOCS Standard and have the capacity and the capability to be compliant at the point of delivery if required.

  • Position your organisation as a forward-thinking company with commitment to ensuring the safest construction vehicle journeys
  • Contribute to the CLOCS programme that is extending geographic reach and driving positive change – supporting the right behaviours and commercial conditions for members to thrive
  • Give your organisation access to early insights and opportunities to influence future developments
  • Provide ongoing support from the CLOCS team, with tools and guidance to accelerate your implementation
  • Include tickets to CLOCS regional events
  • Promote your organisation via the CLOCS Champion portal

Transport for London (TfL) has invested heavily into establishing CLOCS and the national Standard. Whilst that investment continues, much more is needed to accelerate and extend CLOCS awareness and implementation in every UK town and city. So, every CLOCS Champion organisation and others that (1) wish to see rapid reductions in near 500 fatal and serious injury collisions and (2) wish to enjoy benefits of being a Champion are now being asked to contribute into this national campaign, a kind of crowd-source funding – a fair and effective approach.

It will take the same amount of time for the CLOCS team to support a champion irrespective of their size and the membership benefits received are exactly the same. Larger organisations do have higher costs associated with monitoring/accreditation so their contribution to keeping the community safe is proportionate.

Organisations are not obliged to be CLOCS champions to comply with the CLOCS Standard.

Fleet operators: If your fleet operations achieve accreditation to the FORS Silver Standard then you are able to service contracts that are specifying compliance with the CLOCS Standard without being a registered CLOCS Champion.

Construction site operators: You can operate a CLOCS compliant construction site and demonstrate compliance to your client through the CLOCS site monitoring visits. 

Fees will support implementation of the CLOCS Standard by all stakeholders in all parts of the country. We need to:

  • move CLOCS champions from a community of the ‘willing’ to a community of the ‘doing’, providing more support and guidance
  • engage with the regulators in key cities and regions to embed CLOCS in planning and ensure a consistent standard across the UK
  • drive the right behaviours and commercial conditions through procurement

CLOCS encourages all organisations to play their part in protecting vulnerable road users by ensuring best practice in site and fleet operations. CLOCS can be particularly useful in helping small companies to differentiate themselves.

CLOCS is engaging with the regulators in key cities and regions to ensure a consistent standard across the UK. As we progressively work with planners and procurers, the CLOCS Standard will become ‘business as usual’. Being a CLOCS champion is a good way to ‘future-proof’ your business.

The simple answer is – you don’t. If your fleet relevant operations achieve accreditation to the FORS Silver or Gold Standard then you are able to service contracts that are specifying compliance with the CLOCS Standard without being a CLOCS Champion.


This form is part of the CLOCS Compliance Toolkit.  Suppliers may be asked to complete and submit to their client. It enables you to declare the level of compliance against the CLOCS Standard of all vehicles and drivers delivering to, collecting from and servicing projects. Download form

CLOCS applies to contracts where the risk assessment undertaken by the client/developer has identified that proposed construction work presents a risk to vulnerable road users. The developer must clearly specify the scope of the CLOCS Standard e.g. whether it applies to all vehicles or only those above 3.5 tonnes.

If a supplier does not agree with the new requirements then you should explore what rights you, as the client, have written into your contract with them. Most contracts include the ability to make variations through negotiation or arbitration if necessary. 

In the event that a supplier is unwilling to meet the requirements once a contract is signed and agreed then they may be in breach of contract. Early termination is an option and it should be stressed to the supplier that their chances of securing repeat work will be affected.

If you are making changes to existing contracts then the cost and liability of changes should be agreed during the variation process. If it is a new contract then the supplier would be liable for all costs of complying with the requirements, provided they are unequivocally advised during the tender process.

Ask the company to provide detailed evidence of why they think their vehicles should be exempt. 

Ask all suppliers, including foreign vehicles, to provide structured risk assessment and propose mitigation methods to eliminate any risks.


Clients/developers and contractors – to understand how well each of their sites is complying against the National CLOCS Standard, and to identify any areas for improvement (to ensure all reasonable steps have been taken to prevent collisions between HGVs and VRUs).

Vehicle operators – to reassure operators that they will be attending safe sites suitable for their vehicles and to understand that all parts of the supply chain including the client are undertaking their CLOCS responsibilities.

CLOCS team – to understand how well CLOCS Champion’s sites are complying against the National CLOCS Standard, to capture best practice examples, to provide anonymised benchmark data, and to identify opportunities to provide better support/guidance.

Public – safe sites, vehicles and drivers working to a common National CLOCS Standard will help reduce the number of incidents involving vulnerable road users and construction HGVs.

You can download the CLOCS Monitoring Checklist and Preparing for your CLOCS visit guide to help you prepare for the visit. These have been developed together with CLOCS partners the Considerate Constructors Scheme (CCS). Monitors will particularly be looking for evidence of an effective Construction Logistics Plan, traffic routing, suitability of the site for road vehicles with safety features, site access & egress, vehicle loading & unloading areas, control of deliveries/collections at peak times, gate checks to ensure supplier compliance (vehicle & driver) – see section 3.1 of the CLOCS Standard.

CLOCS has partnered with the Considerate Constructor Scheme to use its nationwide team of monitors – reducing costs to all and benefitting from CCS’s 20 years’ experience/success in constructively assessing site compliance against its Code of Considerate Practice. All visits are carried out in a constructive and consultative manner and do not effect the regular CCS audit.

The report remains confidential between CLOCS and the CLOCS Champion. The CLOCS Champion can share the report with others as it chooses. Whilst the report remains confidential, CLOCS may use the anonymous data to benchmark against other Champions.

For CLOCS sites that are already registered with the Considerate Constructor’s Scheme, a CLOCS site compliance monitoring visit will cost £251+VAT per visit when done at the same time as a normal CCS site visit. A CLOCS monitoring visit for a CCS registered site that isn’t done alongside a CCS visit will incur a small additional fee to cover additional travel time.

For sites not registered with CCS, the monitoring fee is £439+VAT per visit

A CLOCS client Champion should ensure that at least 20% of their ‘proposed sites’ each year receive one or more visits from the CLOCS Site Monitoring Team. At least 80% of the sites visited by the CLOCS Site Monitoring Team should be compliant on all 7 aspects of the approved checklist. Non-compliances should be quickly addressed. CLOCS Site Monitoring policy.

Broadly speaking, a site should be assessed every 6-9 months to reflect changes in its related logistics and its impact on the journeys made by HGVs and other vehicles. Experience suggests sites should operate for c. 3 months to allow for set up and to embed arrangements. Equally, the final visit to a site should be at 75% of project duration to ensure any changes effected will make a difference.

All Site Monitoring Visits are completed in a constructive and supportive way to help companies identify ways to improve implementation. There is no direct consequence for a site being found non-compliant as there is not a contractual commitment between CLOCS and a CLOCS Champion. However, a Champion’s status is at risk of suspension if the above policy is not complied with, or at least every effort made to comply, and a reasonable explanation given to the CLOCS team. 

There may be a consequence for a site being found non-compliant if a contractual commitment exists between the site’s operator and another party such as the client or planning authority – and it will be for those parties to resolve.

Email to request your visit. Please provide the following details:

  • Company name
  • Site address
  • Contact name, e-mail address & phone number – ideally both for person requesting a visit and the site manager
  • CCS registration ID (if applicable)


CLOCS is not currently an accrediting body


CLOCS is for regulators, developers and principal contractors to plan, procure and manage construction sites without placing vulnerable road users at risk from vehicles servicing their sites. FORS is an accreditation scheme that enables vehicle operators to demonstrate that their vehicles comply with the CLOCS Standard. View this videograph for further information regarding CLOCS and FORS compatible compliance

The CLOCS Standard requires fleet operators to ensure all vehicle operations meet the requirements as described as Silver in the FORS Standard, addressing the issues of management, vehicles, drivers and operations, and provide acceptable evidence (as defined by each procurer) to demonstrate that requirements have been met.

FORS Silver is completely aligned with CLOCS – if your fleet has FORS Silver or Gold accreditation then it should meet the requirements of the CLOCS Standard.

The FORS website has a list of all registered and accredited companies and their FORS status. If the operator offers an equivalent accreditation they should be required to advise where that can be verified.

CLOCS does not supersede FORS.  FORS helps you demonstrate compliance with the CLOCS Standard. If you are a Silver or Gold FORS accredited company, then you already comply with the CLOCS Standard.

For further information about FORS, please visit or call the helpline on 08448 09 09 44

No, FORS and CLOCS operate independently. You still need to register with CLOCS to be a CLOCS Champion.


The CLOCS team is very lean with limited resource for directly supporting events. However, a number of our Champions are regularly involved in local events and we very happy to make connections. We can also provide logos and artwork available to help you to produce CLOCS branded collateral to promote your event. Please contact for further information.

CLOCS does not have the capability to test, inspect and approve technologies and is not therefore able to recommend or approve products. However, we are always open to offers of sponsorship to underwrite specific events and activities and to support our overall aim of eliminating risk to vulnerable road users.
