Security is a serious business. That's why 4 Site Security is aligned to our industry's leading bodies, ensuring our company and its team members are equipped, ready and trusted to support you today, and every day.

The Security Systems and Alarms Inspection Board (SSAIB) is the leading certification body for organisations providing security systems, fire detection and alarm systems, manned security and monitoring services. The SSAIB assesses 4 Site Security on our CCTV installation and maintenance services and for installing, maintaining, and monitoring intruder alarm systems.

The Security Industry Authority (SIA) was formed by the government in 2003 to administer and license the security industry. 4 Site Security Services Ltd. currently holds SIA Approved Contractor Scheme (ACS) status for the provision of Security Guarding, Keyholding & Public Space CCTV.

ISO 9001 is the internationally recognised standard for quality management systems. Our certification demonstrates that we take quality and customer satisfaction seriously. It tells our clients we will apply good business practice and processes through all our contracts, and work hard to maintain our reputation for quality security services.

ISO 14001 is the internationally recognised standard for environmental management systems. It prescribes controls for activities that impact our environment, including the use of natural resources, handling and treatment of waste and energy consumption. Our compliance and annual recertification demonstrate our commitment to such important issues.

Over the years, local authority professionals in Health & Safety and Procurement - with the Health & Safety Executive's support - have developed the Contractor Health & Safety Assessment Scheme (CHAS). 4 Site Security's Approved Contractor status highlights our desire and capability to meet council expectations.

SafeContractor is an accreditation scheme that assesses the Health & Safety competency of contractors and service providers. As an Approved Contractor, 4 Site Security recognises that Health & Safety plays a key role in providing clients with a safe and secure environment for their employees.

A BAFE Scheme is a set of comprehensive competency requirements that have been developed to incorporate the high quality standards and best working practice for services within the fire safety industry.
