London Operations

Security Services Across London

We support clients across Greater London with site-based security planning and day-to-day operational support. That includes office and corporate security, construction site security, warehouse security, retail security, vacant property security, event security, and general security guard services. Our officers are SIA licensed, BS7858 vetted, fully insured, and backed by supervisor support, clear communication and professional reporting.

Sites We Support

Offices need controlled access, visitor management and a professional front-of-house presence. Construction sites need perimeter checks, contractor access control, delivery monitoring and out-of-hours patrols. Warehouses and logistics facilities often require gatehouse control, vehicle checks, stock area patrols and support around loading schedules. Retail premises need visible officers who can deter theft, monitor customer activity and respond calmly to incidents. Residential developments and mixed-use buildings often need concierge-style access control, patrols of shared areas and support for residents, visitors and contractors. Vacant properties need regular inspections, locking and unlocking, and a clear record of any damage, trespass or maintenance concerns. Events and hotels need officers who can manage entry points, queues, public interaction and incident response without disrupting the site.

How We Operate

We start with the initial enquiry and a practical review of the site, its hours, access points and known risks. From there we assess what the officers need to manage on shift, from patrols and visitor records to deliveries, contractor access, incident response, locking and unlocking, and reporting maintenance or security issues. We assign appropriately licensed officers for the environment, keep communication open with the client and site manager, provide incident and handover reports, and maintain supervisor oversight so the service can be reviewed and adjusted as site conditions change.

London Coverage

Horizon operates across Greater London. Busy commercial districts, industrial estates, logistics hubs, mixed-use developments, construction projects and retail centres all need different security approaches. A site in Central London may need stronger visitor control and front-of-house support. A distribution site on the edge of London may need gatehouse checks, patrols and delivery monitoring across long operating hours. We plan cover around the way each location actually runs. If you need advice on the right level of cover, you can contact our team for a practical review.

London Security FAQs

Answers to common questions from commercial clients looking for security services in London.

What areas of London do you cover?

We operate across Greater London, including Central London, East London, South London, West London and outer boroughs. We plan cover around the site location, access routes, hours of operation and the type of activity taking place on site.

Can you deploy security at short notice?

Yes, where resources and site details allow. If a client needs urgent cover, we first confirm the location, shift times, access arrangements and immediate risks so the officer arrives prepared for the assignment.

Are your officers SIA licensed and vetted?

Yes. Our officers are SIA licensed and BS7858 vetted. We assign officers based on the environment, the duties required and the standard of communication expected on site.

What types of sites do you support?

We work with offices, construction sites, warehouses, logistics facilities, retail premises, residential developments, vacant properties, hotels and event venues. If a site needs access control, patrols, incident response, visitor management or out-of-hours cover, we can review the requirement and advise on the right service.

Do you provide temporary and long-term security?

Yes. We support both short-term and ongoing contracts. Some clients need cover for a few shifts, a weekend event or an emergency gap. Others need a regular officer, a gatehouse team or 24/7 site coverage over a longer period.

How do you decide the right level of security?

We look at how the site operates, who needs access, what needs protecting, when the risks are highest and what duties the officer will carry out. That may include patrols, delivery checks, locking and unlocking, maintaining visitor records, supporting site managers or responding to alarms and incidents.
