Protecting a site in London takes more than putting a guard on the door. London sites rarely look alike. A busy retail unit, a city-centre office and a construction site each face different risks, hours and access challenges, so we plan security around those differences, not around a standard package.
Our SIA-licensed security guards in London are vetted to BS 7858 and matched to the demands of each assignment, so you know who is on your premises and that they are right for the role.
We start with your premises: what you’re protecting, when it’s busiest, and where the risks are. From there, we recommend the right mix of guards, patrols and technology, not a fixed package. That might be a visible guard presence for a retail site, mobile patrols for an empty property, or CCTV alongside patrols where a site needs extra visibility.
We support commercial and public-sector clients across retail, offices, education, healthcare and construction, and we provide corporate security services and event security services in London. Please tell us about your site, and we’ll recommend the right level of cover.

Start with credentials you can check: SIA Approved Contractor status (listed on the SIA register), officers who hold valid SIA licences, and staff vetting to BS 7858.
