We’re proud to share a major milestone: Professional Security achieved an outstanding 140 out of 145 in our latest SIA Approved Contractor Scheme (ACS) audit. This result places us securely in the top 1% of security providers nationwide.
David Fullerton - CEO - Professional Security
Our ACS score of 140 is more than just a number, it is evidence of the high standards embedded throughout our organisation. In a time where compliance is under increasing scrutiny, we don’t wait to be told, we lead from the front. For our clients, this means absolute confidence in the integrity, legality, and reliability of our services.
What is the ACS and why does it matter?
To understand why this score is significant, it’s important to know what the ACS represents. The ACS is the UK security industry’s gold-standard benchmark. Although participation is voluntary, the process is anything but easy.
Specifically, the assessment spans several days and covers 89 performance indicators including:
While scoring 0 is technically enough to pass, very few providers exceed 100. Therefore, achieving 140 is a rare accomplishment that reflects exceptional quality.
How We Set Ourselves Apart
At Professional Security, we don’t aim to simply meet industry standards – we strive to redefine them. Our ACS score reflects a deeply embedded culture of innovation, accountability and continuous improvement.
During the most recent audit, SSAIB assessors highlighted several areas where we demonstrated exceptional practice, including:
Translating Standards Into Real Results
Importantly, our commitment to quality isn’t theoretical, it drives how we deliver on every contract.
A prime example is our growing partnership with the Lawn Tennis Association. Recently, we secured a new three-year agreement to provide security guarding, door supervision, and close protection at various events and locations.
In practice, our Guarding and Event Director uses client concerns and real-world crime data to shape bespoke security strategies. This approach ensures that we meet actual needs – not assumptions – which consistently enhances our service quality.
Spokesperson - Lawn Tennis Association
We gave them our requirements, and they delivered an excellent service, offering guidance on our requirements which may be a better way.
Staying Ahead on Compliance
As regulatory pressure increases: especially in areas like payroll, tax, and labour rights, many businesses must reconsider their supplier choices.
That’s why we launched our Tick Tock Tax O’Clock campaign. Through this initiative, we help buyers:
Unlike many in the sector, we directly employ our workforce. By managing in-house payroll, we ensure every team member is paid correctly and fairly, with verified SIA licences, thorough vetting and full screening in place.
Tom Colman - Group Business Support Director - Professional Security
Our ACS result isn’t just a mark of excellence; it’s proof that our business already meets the highest compliance thresholds being enforced. There’s no risk of exposure, no need for reactive fixes — just robust, ready-made assurance.
Why Our Clients Trust Us
From hospitality and quick-service restaurants to national sports events, our clients choose us not just for operational excellence, but for peace of mind.
Here’s what sets us apart:
Raising the Bar And Expectations
Ultimately, we believe that trust is earned through action, not words. Our ACS score stands as concrete evidence of the standards we uphold every day.
When you choose Professional Security, you’re choosing a partner who is ready – not just to meet expectations, but to raise them.
