Principles and Purpose
Each month thousands of contractors and consultants (suppliers) apply for work with public and private sector
organisations (buyers). To win work, they must meet the buyer’s health and safety standards.
Assessing suppliers health and safety competence is usually a lengthy and time consuming process. Suppliers can sometimes
meet one buyer’s Health and Safety standards but not another. Being CHAS approved reduces duplication as suppliers compliance
is accepted by all CHAS buyers.
CHAS assesses applicants:
- Health and safety policy statement;
- Their organisation for health and safety;
- Their specific health and safety arrangements to a standard acceptable to our buyers and to others.
In 1997 a group of health and safety and procurement professionals from across Great Britain worked with the
Association of London Government (ALG) to develop CHAS. In 2001 CHAS became a web-based system.
CHAS started with two main aims.
- To improve health and safety standards across Great Britain.
- To reduce duplicated safety applications for both suppliers and buyers.
These days we have more than 870 public and private sector buyer organisations, such as councils, housing associations,
including a growing number of large private companies who employ sub-contractors.
Participating in the CHAS scheme helps both suppliers and buyers.
Suppliers show compliance with important parts of health and safety law (the core criteria described in the CDM regulations).
On achieving compliance a supplier is approved to work for all of CHAS' buyers.(Some Buyers may require "Accredited" Status)
Inconsistencies are reduced where some suppliers may be judged compliant by one buyer but not another.
CHAS gives guidance on any weaknesses in a supplier's safety management, including how they can improve.
Being a CHAS supplier or buyer saves both time and resources
The Stages of Assessing Competency
There are three stages in the assessment process from the time a supplier applies for a CHAS assessment, through to
working for a buyer:
The CHAS assessment: if a supplier passes this assessment they have shown they can adequately manage health and safety.
The employer (buyer) checks a supplier has the ability, experience and resources to carry out the specific work they have applied to do.
The buyer will look at things like method statements, specific risk assessments, references, examples of previous similar work,
training and available resources.
Monitoring the supplier when they are doing the work. Buyers will check suppliers are managing the work safely, carrying
out the method statements properly, have enough resources, liaising properly, managing the site effectively and providing enough
The level of assessment at stages 2 and 3 are normally proportionate to the level of risk they carry.
Buyers have a responsibility to monitor suppliers, making sure they are working safely, in order to protect staff and
everyone who may be affected by the work.
Accessing the CHAS Database
Buyers have access to the CHAS database, suppliers you do not have access, other than your own personal pages
if you are accredited. Suppliers cannot access information that relates to other suppliers.
CHAS is registered under the Data Protection Act, but there is no personal information kept in the database about you
(only factual) so there is no information a supplier has right of access to.
However, under normal circumstances the scheme manager will gladly tell suppliers about details contained in their entry.
Buyer Membership Levels
Buyer membership is free. We provide buyers with three levels of access:
Member level: full read and write access
Subscriber level: read only but can add private comments and suppliers to their own supplier list
Read only: allows searches only.
A User ID and password will be issued if you decide to use our scheme.
