CHAS - Contractors Health and Safety Assessment Scheme

CHAS is established as the market leader for Health and Safety pre-qualification in the UK. It is a non-commercial scheme available to suppliers (those who provide goods and services) and to organisations (buyers) looking for suitably competent suppliers.

HCC Buy with confidence​

In response to concerns about ‘rogue traders’ which are often highlighted in the media, a partnership of Local Authority Trading Standards Services have taken a ground-breaking step by putting together the Buy With Confidence Scheme. The scheme provides consumers with a list of local businesses which have given their commitment to trading fairly. Every business listed has undergone a series of detailed checks before being approved as a member of the scheme.


The UK’s largest register for pre-qualified contractors and consultants. In terms of efficiency, time and cost saving and best practice, constructionline is proven to deliver for public and private sector organisations alike. Recommended by the OGC Common Minimum Standards and The Local Government Task Force.

UVDB - Utility Vendors Database

UVDB is operated as a ‘qualification system’ under article 30 of the EC Utility Directives. Information is gathered about suppliers, e.g. financial performance, health, safety, environmental policy, CSR, products and services data and is checked for accuracy and that it is up-to-date. The information is then made available online to the buyer.
