SIA Approved Contractor
RMSS LTD is approved under the Security Industry Authority's Approved Contractor Scheme for security guarding. You do not have to take our word for it: you can check it yourself on the SIA register.
The Scheme
What Is The Approved Contractor Scheme?
The Approved Contractor Scheme (ACS) is a voluntary scheme run by the Security Industry Authority (SIA), the regulator of the private security industry in the UK. Security companies that join are independently assessed, and those that meet the standard are listed on a public register.
For anyone buying security, it is a quick and objective way to compare suppliers before you appoint one.
Why It Matters
What Approval Means When You Hire Security
Four things worth knowing before you choose a security supplier.
Independently assessed
Approval is based on an independent assessment of the company, not just on what the company says about itself.
Publicly checkable
Every approved contractor appears on the SIA's public register, so you can confirm a supplier's status yourself in a minute.
Specific to the service
Approval covers named services. RMSS LTD is approved for security guarding, so always check that a supplier's approval matches what you need.
Companies and individuals
The scheme approves companies. SIA licences are issued to individuals, so a good supplier will also show you its officers' licences where a licence is required.

Questions worth asking any security supplier
- Is the company approved under the scheme, and for which services?
- Which SIA licences do the officers who will attend your site hold?
- What training do they receive?
- What insurance does the company carry?
- How will the deployment be planned around your site, and what are the contract terms?

Questions
Frequently Asked Questions
Is the Approved Contractor Scheme the same as an SIA licence?
No. SIA licences are issued to individual security operatives. The Approved Contractor Scheme approves companies. A good supplier will be able to show you its officers' licences where a licence is required, as well as its company approval.
Is approval under the scheme compulsory?
No, it is voluntary. Companies choose to be assessed, which is why approval is a useful way to tell suppliers apart.
How can I check that a security company is approved?
Use the SIA's public register of approved contractors. Approval covers named services, so check that it matches what you need. You can check RMSS LTD on the register using the link on this page.

What else should I ask a security supplier?
