Our accreditations and suppliers


ISO 9001

The most widely recognised standard is ISO 9001, a basic quality management system that can be used in industries of any size, anywhere in the world.

Registration to ISO 9001 (or other quality management standards) provides objective proof that a business has implemented an effective quality management system, and that it satisfies all of the requirements of the applicable standard. An external, impartial expert called a registrar or CB (Certification Body) conducts an on-site audit to determine whether or not a company is in conformance to the standard. If they are found to be in conformance, they will be issued a certificate showing their address, scope of operations and the seals of the accreditation bodies that give the registrar its legitimacy.

ISO 14001

ISO 14001 was developed to provide a management system to help organisations reduce their environmental impact. The standard provides the framework for organisations to demonstrate their commitment to the environmental by:

  • Reducing harmful effects on the environment
  • Providing evidence of continual improvement of Environmental Management

The standard is generic and does not apply to any particular industry or business sector. It provides a strategic framework that can be used to meet internal and external objectives for Environmental Management.

EUSR is designed to support industry employers and add value to the sector. As the Sector Skills Council (SSC) the gas, power, waste management and water industries, Energy & Utility Skills (EU Skills) operates an independent skills platform, referred to as EUSR, which provides recognised standards for the utility sector.

Individuals who qualify for registration with EUSR are issued with a card and appear on the EUSR website.

EUSR is beneficial to both employers and individuals as they move between companies or between industries. Employers have a robust way of verifying the abilities of their workers while individuals have a recognised method of demonstrating their abilities to employers.

SSIP Membership

SMAS is a proud member of the Safety Schemes in Procurement (SSIP) Forum.

Since the launch of SSIP, many Clients and Principal Contractors now adopt an SSIP approach to H&S pre-qualification and will only use contractors who hold a valid and in date certificate issued by an SSIP Member Scheme.

Holding a valid SSIP Member Scheme certificate means that a contractor has demonstrated their capability by meeting the SSIP ‘core criteria’.

A key aim of the SSIP Forum is to reduce the burden and cost of H&S bureaucracy across the construction industry and as part of this, contractors holding a SMAS H&S certificate will be recognised by the other Member Schemes who offer mutual recognition
