Veriforce CHAS accreditation via ATaC

ATaC offers members cost-efficient routes to CHAS accreditation.

ATaC members are eligible for a discount on CHAS Standard, CHAS Advanced and CHAS Elite packages.

Please note that as of 20th October 2021 CHAS membership packages have been renamed.

CHAS Elite

Formerly know as CHAS Premier Package (Common Assessment Standard)

As an ATaC member, you will be eligible for a 20% discount when making a new application for the CHAS Elite accreditation.

This can result in a significant saving!

Also, as ATaC members you can gain a 10% discount when renewing your CHAS Elite accreditation.

The Common Assessment Standard (CAS) accreditation was designed to standardise the prequalification process, helping both clients and contractors improve supply chain efficiency, reduce supply chain risks, and find reliable business opportunities.

To apply and receive the discount, first call ATaC on 01283 505765 for a discount code and then you can submit a new application or renewal via an ATaC/CHAS webpage, or contact Veriforce CHAS on 0345 5219111.

CHAS Advanced

Formerly know as CHAS Premium Plus

ATaC members are eligible for a 20% discount when making a new application for CHAS Advanced, and a 10% discount when renewing this accreditation.

As well as covering health and safety, this package also includes assessments on areas such as financial standing and quality management. Information on all the areas covered by this package is available on the CHAS website.

To apply and receive the discount, first call ATaC on 01283 505765 for a discount code and then you can submit a new application or renewal via an ATaC/CHAS webpage or contact Veriforce CHAS on 0345 5219111.

CHAS Standard

Formerly know as CHAS (H&S)

ATaC members can obtain a 20% discount when applying for a new CHAS Standard accreditation and a 10% discount on a renewal.

To apply and receive the discount, first call ATaC on 01283 505765 for a discount code and then members can submit a new application or renewal via an ATaC/CHAS webpage or contact Veriforce CHAS on 0345 5219111.

The online application process includes a declaration, and documentation will need to be uploaded as evidence to support the application.  Please note that all sections must be completed for a successful submission.  An ATaC Member User Guide, which provides a step-by-step guide through the CHAS Standard application process and guidance on supporting evidence, is available in the ATaC Members’ portal. Once the application is submitted a CHAS assessor will then audit the documentation prior to CHAS accreditation confirmation.

What does this mean for ATaC Members?

When applying for Veriforce CHAS accreditation, organisations need to confirm their total number of employees (office and site staff), as the cost of accreditation is banded. Information on the costs for all bands is available on the CHAS website.

ATaC members can obtain a 20% discount, available across all bandings, when applying for a new accreditation and a 10% discount on a renewal.
