How to Choose a Security Company (12-Point Checklist)

Start with credentials you can verify: SIA Approved Contractor Scheme membership where relevant, employers’ liability and public liability at sensible limits, and references from sites similar to yours. Ask how turnover works on your contract — named supervisors, minimum staffing on critical shifts, and how absence is backfilled — and read the SLA in plain language rather than trusting a glossy brochure.

A strong supplier will walk your site before pricing, challenge unrealistic budgets, and explain trade-offs clearly. Weak ones will underbid and recover margin by thinning cover later. If something in the tender feels vague on training, debriefing after incidents, or communication with your team, fix it in the contract now; operational drift is expensive to unpick after mobilisation.
