SafeContractor accreditedSafeContractor

Trinity has accreditation from SafeContractor for commitment to achieving excellence in health and safety.

SafeContractor is a leading third party accreditation scheme which recognises very high standards in health and safety management amongst UK contractors.

Under the SafeContractor scheme, businesses undergo a vetting process which examines health and safety procedures and their track record for safe practice. Those companies meeting the high standard are included on a database, which is accessible to registered users only via a website.

Client-organisations who sign up to the scheme can access the database, enabling them to vet potential contractors before they even set foot on site. These clients agree that, as users of the scheme, they will engage only those who have received accreditation.

Major nation-wide businesses from several key sectors have signed up to use the scheme when selecting contractors for services such as building, cleaning, maintenance, refurbishment or electrical and mechanical work.

CHAS AccreditationCHAS

CHAS (The Contractors Health and Safety Assessment Scheme) was created by experienced health and safety professionals in 1997 to improve health and safety standards across the UK.

In partnership with the Association of London Government (ALG), CHAS was a key developer of the core criteria held in the Approved Code of Practice which supported the Construction (Design and Management) Regulations 2007 (now recogonised as CDM 2015) and is a founder member of SSIP (Safety Schemes in Procurement). As one of the founders of third party accreditation we are not only a trusted advisor on health and safety compliance, we are an authority. We set industry bench marks, provide assurance and reassurance, and offer best-in-class service s that are easy to use and cost effective.

This health and safety legislation was created to achieve the following aims:
• To simplify health and safety contractor assessment by standardising requirements.
• To allow companies to avoid undergoing health and safety assess ments for every job.

We have more than 900 public and private sector client organisations and 70,000 contractors registered on the CHAS database.
