For security and events companies weighing up the Approved Contractor Scheme. It is the question I get asked more than any other. A security company calls, they have heard they should have ACS, a client has mentioned it or a competitor has it on their website. And
they want me to tell them whether they need it.
I never answer that question directly. I answer it with a question of my own.
Do your clients want you to have it?
Because that is what it really comes down to. The Approved Contractor Scheme is voluntary. It is not the law. You do not need it to operate, to bid or to win work. Plenty of good security companies trade for years without it. So if I told you “yes, you need ACS,” I would be selling you something rather than advising you. That is not how I work.
What ACS actually is.
ACS is the SIA's voluntary scheme for the physical side of security - guarding, door supervision, key holding, mobile patrols Close Protection, and the like. When you achieve it, you have opened your management systems and your people up to independent inspection and met a defined standard. One of three assessing bodies does that inspection on the SIA's behalf: NSI, SSAIB or the British Assessment Bureau.
It does not give you permission to trade. You already have that. What it does is give a buyer a reason to trust you before they have ever met you. It tells them you work to a set standard and that someone independent has checked. That is genuinely valuable. But only if your buyers care.
Who cares if you achieve ACS?
Here is the honest test. If your clients are not asking about ACS and your tenders are not requesting it, then you have to ask yourself why you would spend the money and the management time to get it. Sometimes the answer is still yes. You might be trying to move up into larger commercial or public-sector contracts where it gets asked for routinely. You might want to stand alongside competitors who already hold it. You might simply want the discipline that the assessment brings to your business. All good reasons. But “a competitor has it” is not, on its own, a reason. Neither is “I heard I should.” The question is whether the buyers you want are looking for it. If they are, it earns its place. If they are not, your money may be better spent elsewhere investing in other certification like ISO 9001 or SSIP which can you find out more about on my website.
It is not a magic bullet
One thing I am always straight about. ACS is not something a consultant does to your business while you carry on as you were. I can bring you the templates, the policies, the procedures, everything you need to meet the standard. But a management system you do not understand and do not use is not a management system. The assessors know the difference. They want to speak to your top management. They want to see the system working in practice, not sitting in a folder. So whatever you decide, go in knowing this: the certificate is earned by your business doing the work, not by paperwork appearing on a shelf.
My job is to make sure you understand the system and can stand behind it. The evidence has to come from you.
The bottom line
If you are weighing up ACS, do not start with the scheme. Start with your buyers. Find out what they actually ask for, and let that drive the decision. And if you do go for it, treat it as something you are building into how the business runs - not a badge you bolt on and forget. If you want to talk it through honestly, with no pressure either way, that is exactly the conversation I like to have. Get in touch here
