The National Security Inspectorate (NSI) is the flagship accreditation for the security industry, providing high quality audits of business security and fire safety service providers. This ensures that we work to the highest industry standards and are monitored twice year for the quality of our workmanship, office processes and financial health.

NSI Gold means we provide reassurance to our chosen contractors that we work to high standards and provide benefits to our customers insurance costs. For example, certain insurance companies will only give you coverage if you have NSI approval. Additionally, if the company who install your intruder alarm are not certified by NSI or similar, the police wont respond to your alarm. NSI services are continually being adapted and developed to ensure that we are keeping up to the highest standards of the sector.

All NSI companies: 

·        Meet high business performancestandards

·        Meet all relevant British and EuropeanStandards for technical performance

·        Security screen all relevant staff

·        Provide a high level of staff trainingand supervision to industry best practice

·        Are comprehensively insured throughspecialist insurance to protect customers

·        NACOSS Gold companies also meetindustry specific ISO 9001 Quality Management System standard requirements.

NSI Gold is different to NSI Silver as there is an extra level of assessment. As well as being product certified (NSI Silver) the gold standard builds on this to incorporate a Quality Management System Certification. NSI define a management system as: 'A proven framework for managing and continually improving an organisations policies, procedures and processes.' Management systems applications include:

·        Quality-BS EN ISO 9001

·        Environmental-BS EN ISO 14001

·        Healthand Safety- BS OHSAS 18001

As part of the management certification, Omega is ISO 9001:2015 accredited. This is designed to help organisations ensure that they meet the needs of customers an other stakeholders while meeting statutory and regulatory requirements related to a product or programme. This ensures that we deliver good quality products and services in customer focus, motivation of top management and continual improvement.

Omega are accredited through an existing SSIP for environmental accreditation, however we will also be working towards the environmental 14001 accreditation in the near future. This accreditation provides the tools for companies looking to manage their environmental responsibilities.
