Frequently asked questions
Straight answers about how we work, what we're accredited to, and how we handle your data.
What is BS 7858 and why does it matter?
BS 7858 is the British Standard for the security screening of individuals working in environments where people, assets or data are at risk. It covers identity, employment history and criminal-record checks. Every Arthur Security guard is BS 7858 screened, so you know exactly who is protecting your site.
How fast do you respond to incidents?
Response times scale to the incident. Emergencies are answered in 2–5 minutes; routine matters in 10–30 minutes. We set clear expectations in your assignment instructions so there are no surprises.
Why do you use the same guards on a site?
Continuity is our single biggest advantage. Guards who stay on a site for 3–4+ years learn its rhythms, people and weak points. They prevent incidents because they notice what is out of place — something a rotating, unfamiliar guard simply cannot do.
What is included in a free risk assessment?
A site walkthrough, vulnerability identification, threat assessment and a written solutions proposal. It takes around 30 minutes on site, and you receive your report within 3–5 business days. There is no obligation and no hard sell.
Are you SIA licensed and accredited?
All deployed officers hold the appropriate SIA licences for their role. As a company we operate to BS 7858, BS 7499, BS 10800 and ISO 9001, and we are working through the SIA Approved Contractor Scheme (ACS) — our first audit is in progress.
How do you comply with GDPR?
We collect only the data we need, store it securely (encrypted, UK-based), and never sell it. You can access, correct or delete your data at any time. Full details are in our Privacy Policy, and every form on this site captures explicit consent before we contact you.
What is your service area?
We serve Greater London and surrounding areas. If you are just outside our usual radius, contact us anyway — we will tell you honestly whether we can cover you well.
Can I get a custom quote?
Yes. Pricing depends on your site, hours and risk profile, so we quote after a short risk assessment rather than guessing. Use the chatbot or contact form to book one — it is free and there is no obligation.
What is the First/Last Patrol Protocol?
Every shift opens and closes with a structured patrol that documents the state of your site, flags anything that has changed and deters opportunists. It turns guarding from a passive presence into proactive risk management.
What is the GSS Guard Patrol app?
GSS is our guard-management platform providing real-time patrol tracking, incident reporting and a client portal. It gives you live visibility of what is happening on your site. (Client portal rollout in progress.)
