National Security Inspectorate (NSI) NACOSS Gold

The National Security Inspectorate is an independent not-for-profit supervisory body that is responsible for ensuring its member companies are fully compliant with security industry standards and codes of practice. It is widely recognised as the leading certification body for the security sector in the UK.

NSI works closely with UK Government bodies and other agencies such as the Security Industry Authority and is one of the UK’s key specialist certification bodies, auditing and providing certification to the industries’ small and medium sized enterprises, as well as major global providers.

In order to achieve the NACOSS Gold recognition, a company must demonstrate its technical ability to design, install and maintain equipment to all relevant European Standards and NACOSS Codes of Practice. The suitability of the company’s premises, vehicles, insurance, staff security vetting and training, procedures and protocols on customer service are all audited as part of the certification process.

The NACOSS Gold Certification builds on product Certification to incorporate Quality Management System Certification. The combination of the Quality Management Systems and the relevant sector specific product or service represents the Gold standard of certification. This level holds the greatest perceived value across industry and by the police, fire and rescue services and insurers.

CSCS (Construction Skills Certification Scheme)

CSCS (Construction Skills Certification Scheme) is the leading skills certification scheme within the UK construction industry. CSCS cards provide proof that individuals working on construction sites have the required training and qualifications for the type of work they carry out.

The Scheme keeps a database of people working in construction who have achieved, or are committed to achieving a recognised construction related qualification. Most principal contractors and major house builders require construction workers on their sites to hold a valid CSCS card.

Tensor has achieved IT partner status with the CSCS in 2013. We have developed our .NET suite of products to allow a seamless integration between the CSCS smartcard and our Access Control, Time Management, Visitor/Contractor Management and Fire/Evacuation roll-call systems, including Turnstiles and Biometric verification devices (facial recognition, hand scanning & fingerprint recognition).

The integration allows a “one card fits all” philosophy where Contractors who attend CSCS sites use their existing CSCS smartcard to not only identify them as a CSCS certified tradesman, but also to clock in/out of site for presence monitoring, grant access to the site and log them on and off the evacuation roll-call which is automatically printed when an alarm is triggered.
