Corporate Security London: A Guide to Building a Layered Security Plan

Author : Security Guards London Limited | Published On : 06 Nov 2026

According to the Home Office, roughly four in ten workplaces with ten or more staff in England and Wales experienced crime in a single year. Effective corporate security in London rarely depends on one measure. It is a layered plan made up of trained personnel at entry points, access control that is consistently enforced, appropriate out-of-hours cover and a provider that can be held accountable.

Where Corporate Premises Are Exposed

The Home Office’s 2023 Commercial Victimisation Survey estimated that 26% of business premises in England and Wales, around 409,000, experienced crime in the previous 12 months. Theft was the most common offence at 14%, followed by burglary and vandalism at 8% each, and assaults or threats at 7%.

Premises size and public access both influence risk:

  • Premises with 10 to 49 employees (42%) and 50 or more (39%) were affected more often than those with up to nine (24%).

  • 29% of publicly accessible premises reported crime, compared with 20% of those closed to the public.

  • Only 55% of victims reported the crime to the police. Among those who did, 41% were dissatisfied with the response and 35% were satisfied.

Where crime occurred, 50% of victims reported a direct financial loss and 49% lost additional staff time dealing with it. These are national figures and are best treated as a benchmark rather than a London forecast.

In practice, common weak points are routine ones: unverified visitors, doors propped open by contractors, unattended loading bays and empty buildings at night.

What Corporate Security Services in London Should Include

Corporate security services in London should begin with a risk assessment rather than a rota. The assessment determines where access is controlled, how visitors are verified, what patrol schedule suits the building and who is notified when an incident occurs.

In multi-tenant buildings, responsibilities should also be agreed with the managing agent so that nothing falls between reception, landlord and tenant security. The following should be requested in writing:

  • Access control and visitor procedures

  • Patrol and handover routines

  • Incident escalation

  • A named contact on the management side

The Role of Corporate Security Guards

Corporate security guards combine security duties with front-of-house conduct. At reception, they verify visitors, challenge tailgating, manage deliveries and maintain calm during an evacuation, while representing the organisation’s brand. They also keep accurate logs and incident reports, which are important when an event needs to be reviewed or reported.

Effective guards are briefed on the specific building, its tenants and its visitor rules, not only its address.

Licensing is a legal requirement. The government states that anyone guarding premises against theft, damage or unauthorised access needs an SIA security guard licence when working under a contract for services. The SIA also publishes a register of licence holders, which makes verification straightforward.

Extending Protection After Hours With Dog Security

Car parks, yards and isolated perimeters are difficult to cover overnight with personnel alone. Dog security in London can provide a strong deterrent and a faster response to movement on larger sites, working alongside guards and CCTV monitoring.

There is no separate SIA licence for dog handlers, but their duties will usually fall under security guarding licensing. Dog units are not suitable for every building, so the risk assessment should decide, taking into account access, noise and neighbouring properties. Our dog security page explains how units are deployed.

Corporate Events and Visitor Surges

Product launches, AGMs and client evenings change a building’s risk profile significantly. Attendance rises, there are more entrances in use and staff are less familiar with those on site.

Event security in London should cover guest lists, access checks, crowd flow and a clear escalation route. The team should be briefed on the guest list the day before the event rather than at the door. See our event security service for how this works in practice.

Martyn’s Law is also relevant. It applies to premises or events that are publicly accessible with a capacity of 200 or more. The Act received Royal Assent on 3 April 2025, with an implementation period of at least 24 months, so planning should begin now.

Choosing a Provider

When comparing security guards in London, evidence is more useful than general claims. Recommended checks include:

  • Verifying SIA licences.

  • Asking who supervises the site and how often.

  • Requesting written assignment instructions.

  • Establishing what happens when a guard is absent.

  • Asking to see a sample incident report.

  • Asking whether the provider holds the SIA’s Approved Contractor Scheme status, which is voluntary and assessed at company level.

Percentage claims about crime reduction that do not name a source should be treated with caution.

Planning Security That Fits Your Premises

Security Guards London Limited has completed over 368 projects across 132 areas, with SIA-licensed personnel, 24/7 support and hands-on management. Where cover is urgent, personnel can often be arranged within a few hours, depending on location, staffing requirements, risk assessment, licensing and briefing.

Security is not a one-off purchase. Reviews after an incident, a tenant change or an office move keep the plan matched to the building, and arrangements are adjusted as requirements change. To discuss your risks and a tailored quotation, contact Security Guards London Limited or visit sglondon.uk.

Key takeaway

Corporate security works best as a set of layers. Assess the risks first, place licensed personnel where access is controlled, add dogs or event cover where the risk changes, and judge providers on evidence
