About us

Security built on trust

GMB Security Ltd is based in Mildenhall, Suffolk, and provides SIA licensed guards for commercial premises, venues, events and construction sites across England, Scotland and Wales, as well as live CCTV monitoring. Whatever you need protecting, we provide the right guards for the job, from a single shift to a long-term contract.

Every guard we place is vetted to BS7858, trained for the role and fully briefed on your premises before their first shift. We keep communication simple, so you always know who is on duty and how to reach us.

Health and safety comes first in everything we do. Before work starts, we assess the risks at each location, brief our guards on your rules and emergency procedures, and make sure they have the right PPE. Guards working alone have regular welfare check-ins, and every incident is reported and reviewed so we keep improving.

No two businesses or events are the same. We can be flexible to meet your needs, whether you need one guard for a weekend or a full team for a long-term project.
