How to Choose a Security Company in the UK: 9 Questions to Ask First

The UK security market ranges from national approved contractors to a man with a van and a high-vis jacket, and from the outside they can look surprisingly similar. These nine questions cut through the pitch — and the quality of the answers tells you almost everything.

The compliance questions

One: are you an SIA Approved Contractor? Two: can I have the licence numbers of the officers you propose for my site, to verify on the SIA register? Three: are all officers vetted to BS 7858, and can I see evidence? Four: what insurance do you carry — public liability, employer's liability and efficacy cover — and can I see certificates? Any hesitation on these four ends the conversation.

The delivery questions

Five: how do you prove attendance — look for GPS-verified patrols, NFC checkpoints and digital reporting, not promises. Six: who supervises the contract and how often do they visit site? Seven: what is your relief and no-show procedure — because officers get sick, and the answer reveals whether there is real infrastructure behind the salesperson.

“Ask nine questions. The quality of the answers tells you almost everything.”

The partnership questions

Eight: what training do officers receive beyond the licence minimum — first aid, conflict management, counter-terrorism awareness? Nine: how do you measure and report performance, and what happens if we are not happy? A professional provider answers with KPIs, monthly reporting and a named contract manager.

Run these nine questions past three providers and the right choice usually makes itself.
