Approved Contractor Scheme / ISO 9000 Audit Success – May 2026


The Security Industry Authority (SIA) is the body responsible for maintaining the standards of companies providing security services to businesses and private individuals in the UK.

In order to work in this area, any individual needs to apply for a licence and pass the necessary tests and checks. For companies, a similar scheme is in operation, this being the Approved Contractor Scheme (ACS).

In order to obtain (and maintain) membership of the ACS, firms have to pass an annual audit check. To pass, the firm must demonstrate that it meets the required standards for management, service delivery, customer care and staff welfare.

17 Point Increase

Needless to say, Wye Security have held this accreditation for many years now, but this year we have managed to scale new heights, improving our score by 17 points over our score in 2025.

This means that we have a 77 point score, putting us on track to reach the standards of the top 20% in the whole of the UK.

Incorporated into the scheme is the well known ISO 9000 certification, this being all about quality management and standards. Our prowess in this area is one reason our score increased so dramatically this year.

The areas we improved on this year.

There are quite a few, the highlights being:-

  • The creation of a database that controls the functions and management of the company, this containing all the site information required.

  • The enhancements made to the tracking of site visits and reports database. This is an online system allowing our clients to check up on the reports about visits to their premises and any reports and issues.

  • Setting up E- Learning courses for our security staff, thus allowing them to keep abreast of trends in the industry.

  • The fact that we have now become 100% paperless, which enhances our green credentials and means we are ‘doing our bit’ for the planet.

This increased score demonstrates our commitment to providing the very best service to our customers.
