Approved Contractor Scheme

It is a voluntary program managed by SIA that measures security suppliers against the standards of independent evaluation. The ACS was established in 2006 with a stated purpose ‘to protect the public and to maintain and improve standards in the private security industry’. The Approved Contractor Scheme accreditation provides buyers with independent proof of a contractor’s commitment to quality. There are currently 748+ approved contractors and more than 134,000 licensed operatives work for one of these companies.

Routes to Approval

There are two routes to gaining ACS accredited status. These are equivalent to each other and ensure that the standards required of all approved contractors are consistent.

Standard Route

Open to all companies – no previous accreditation required. The Standard route to ACS approval begins with a self-assessment that is then verified by an independent assessor from an SIA-approved assessing body.

Passport Route

We accredit certain alternative quality assurance schemes as being equivalent to the ACS Standard. If your business is accredited under one of these schemes you take the Passport route to ACS approval.

“The SIA’s Approved Contractor Scheme (ACS) gives a perceived sign of value inside the private security industry. ACS organisations are thoroughly evaluated against international standards; causing their clients to settle on choices that depend on quality and worth. At the point when you as a customer pick a security provider SIA’s ACS – Why choosing an Approved Contractor who is a Security Industry Authority (SIA) affirmed security worker, you can be certain that the business you are working with has been autonomously checked also, is one of the top providers in the area. Any organisation that is important for the plan has decided to be. ACS is a reformist quality norm.”

Benefits of getting SIA’s ACS status

Getting SIA ACS status is an effective way for private security companies to evidence that they are offering a quality service to their customers which are trusted through operating ethically, legally and hiring licensed trained security staff who have been properly screened.

Having SIA ACS status is not only helping the SIA fulfilling its main objective of protecting the general public, but it also provides confidence to all stakeholders, for example, customers, consumers, the police force and end-users, that they are dealing with a highly professional security company.

Security companies must meet the SIA ACS standard criteria to achieve approval. The necessities are generic and may be applied to any or all organisations no matter their size or sector. The factors are divided into several sub-criteria that when met, should demonstrate how excellent service delivery and sound business management are achieved.

SIA ACS approval is a wellspring of certainty for purchasers of safety administrations. Its system for setting, improving and checking working principles is progressively turning into the base prerequisite for any organization sending a security administration. SIA ACS endorsement is deliberate and in a split second positions your organization as having been freely evaluated and meeting a perceived degree of execution.

ACS covers those pieces of the business managed by the SIA and the Private Security Industry Act 2001 (as changed), requiring the SIA to set up an “arrangement of examination for suppliers of safety administrations, under which those associations who sufficiently satisfy the concurred guidelines might be enrolled as endorsed and may promote themselves accordingly”.

Being an SIA Approved Contractor shows that your company is more concerned about client support and gives consolation your private security agents convey quality assistance in any of the attaching to territories where you decide to be evaluated.

Application requirements

Before being assessed a security company’s application to the standard is accepted by the SIA, the directors and business owners – those with a controlling influence (recorded on Companies House) – they must meet the fit and proper due diligence checks. The checks are included any previous convictions and trends of liquidating companies. Once the application is successful, the company can move to the next stage which is the assessment stage, which must be carried out by an SIA ACS approved certification body. Currently, there are four certification bodies that security firms can choose from. These assessment bodies are UKAS accredited. The four bodies are:

The Need for SIA ACS

Organisations within the safety industry won’t give much thought to what some consider ‘additional certification’ thinking that because they meet the minimum legal obligations that there is no need for anything else outside of the compulsory licensing requirements.

The Private Security Act of 2001, Sections 3 and Schedule 2, define the kinds of firms that might got to apply for licensing as;

Security Guarding

Door Supervision

Public Space Surveillance

Key Holding

Close Protection

Cash and Valuables in Transit

Those who are unsure then should seek further advice as conducting business without a license may be a criminal offence and may end in a £5,000 and even six-months in prison.
