SSIP: Safety Schemes In Procurement:

SSIP was created as an umbrella organization that facilitates mutual understanding and recognition between different health and safety schemes to ensure uniformity. One of the most important functions of the SSIP forum is to advise procurement teams on how to interpret different health and safety standards in the UK and whether they are meeting the requirements for both preferred supplier lists and individual contracts. This process streamlines the tender process for both buyers, helping them create a more cost-effective process of identifying suitable suppliers, and companies, by providing automatic prequalification for contracts within their sector and capabilities.
