CHAS Accreditation
CHAS accreditation is often requested before a transport contractor is allowed onto construction sites, depots, utilities projects or client premises. For operators, it is not just a generic health and safety badge. The evidence has to show how vehicles, drivers, loading teams and managers control the real risks around site access, reversing, loading and unloading, working at height, manual handling and vulnerable road users.
This page explains what CHAS assesses, how Standard, Advanced and Elite differ, and what a transport business should prepare before applying or renewing.

What CHAS assesses across its accreditation levels
CHAS has three accreditation levels. The right one depends on the contract, the buyer and the risk profile of the work.
CHAS Standard covers core health and safety management and provides SSIP accreditation, which many construction and maintenance buyers use as the baseline. For most transport contractors tendering for routine site, depot or delivery work, Standard is the starting point.
CHAS Advanced adds wider assurance areas on top of the health and safety assessment, including environmental management, equality and diversity, quality assurance and financial standing. Some larger clients and frameworks ask for this wider evidence.
CHAS Elite is the highest level and aligns with the Common Assessment Standard used on many public sector and major construction works contracts. It is not automatically required for every job, so check the tender wording before applying.
For transport contractors, the assessor will expect evidence that matches the operation. That means a health and safety policy, transport-related risk assessments, RAMS for higher-risk tasks, training and competence records, incident procedures, first aid arrangements, insurance and access to competent health and safety advice.
CHAS sits inside the SSIP framework, so mutual recognition can apply with other SSIP member schemes where the buyer accepts it. In practice some buyers still ask for CHAS by name, and some specify a particular level, so check the exact wording in the tender or framework before you choose what to apply for.
The CHAS assessment process and annual renewal
CHAS is assessed online. You submit your evidence through the CHAS portal and an assessor reviews it against the level you have chosen. Standard assessments are usually completed without a site visit, while Advanced and Elite call for more evidence and take longer to work through.
Accreditation lasts 12 months. Renewal means more than resubmitting last year’s file. Policies, training and competence records, insurance certificates and risk assessments all need to be current on the date the assessor reviews them, and they need to reflect any change in your fleet, client sites or driver tasks. An assessor and a client auditor will both notice a RAMS document that still carries last year’s review date or describes vehicles you no longer run.
Costs vary by company size and accreditation level and are published by CHAS. Buyers with database access can confirm your status directly, which is part of why the accreditation carries weight in procurement.
Andrew Logan, transport compliance specialist: “The applications that come back for more information are nearly always the ones where the paperwork does not match the operation. CHAS is not testing how well you can fill in a form. It is testing whether the document in front of the assessor would actually keep a driver safe on a client’s site.”
Who needs CHAS and when it is specified
CHAS is commonly requested by construction clients, principal contractors, utilities, facilities management providers and public sector buyers as part of contractor pre-qualification.
For transport contractors it is most relevant where vehicles, drivers or loading teams attend controlled environments: live construction projects, utilities sites, depots, distribution centres, waste and recycling sites and client premises. The client may ask for CHAS by name, or for SSIP or Common Assessment Standard evidence more generally. On construction and utilities work it is often specified alongside FORS Bronze and, on relevant projects, CLOCS, because those schemes cover the road risk side that a health and safety scheme does not reach.
Do not assume one accreditation level fits every contract. A small subcontractor delivering to a site may need only Standard, while a contractor bidding for a public sector framework may be told to hold Elite. Check the tender, framework or client wording before you apply, so you pay for and prepare the level you actually need.
Useful records and next steps
CHAS accreditation: six areas to prepare
CHAS evidence should reflect the work your vehicles, drivers and site teams actually carry out, not a set of documents that could apply to any contractor.
Prepare these six areas before applying: health and safety policy and competent advice; transport-specific risk assessments and RAMS; driver induction and site access; training and competence; accident and near-miss reporting; insurance and first aid.
CHAS Standard
Health and safety policy, responsibilities and competent advice.
CHAS Advanced
Risk assessments and method statements for transport activities, including loading, unloading, reversing, site access and working near pedestrians.
CHAS Elite (CAS)
Driver and worker competence records, including inductions, toolbox talks and task-specific training.
SSIP Mutual Recognition
Insurance, accident reporting, near-miss reporting and investigation arrangements.
Annual Renewal
Vehicle, equipment and maintenance control evidence where it affects site safety.
Buyer Visibility
Environmental, quality, equality and supply chain information where required by the CHAS level or client contract.

Get help with your CHAS application
Operator Licence Ltd can help review your CHAS evidence, identify the gaps and connect you with the right specialist support so your application reflects day-to-day transport operations rather than generic paperwork. That includes checking that your RAMS match real driver tasks, that training and insurance records are current for renewal, and that the level you apply for fits the contracts you are bidding for.
CHAS application checklist for transport contractors
Before you submit a CHAS application, check that your evidence is current, signed where required and specific to transport operations.
Include a signed and dated health and safety policy, current employers’ and public liability insurance certificates, transport-specific risk assessments, RAMS for higher-risk tasks, driver induction records, toolbox talk records, training and competence evidence, accident and near-miss reporting arrangements, first aid arrangements and proof of competent health and safety advice.
For transport work, confirm the evidence covers loading and unloading, reversing, site access and arrival procedures, coupling and uncoupling, working at height, manual handling, vehicle movements, vulnerable road users, maintenance activity and any client-specific site rules. If a task happens on a client site, it should be visible somewhere in the file.
