When your security guard leaves for 2 minutes

This incident took place at a listed building in Clerkenwell. A high-value property. Security in place. On paper, everything appeared to be properly covered.

Until it wasn’t.

The security guard stepped away briefly to attend to a personal matter. In that short window, someone entered the building and locked the door behind them.

That was all it took. Within minutes, the site had been compromised. What followed was a rapid escalation. The property was effectively occupied, and the owners were left dealing with the consequences of what looked like a functioning security arrangement, but ultimately wasn’t designed or managed effectively enough to prevent a breach.

This is where the real issue with low-grade or poorly structured security becomes clear.

It creates an illusion of protection rather than delivering genuine control of risk.

Having a guard physically present is not the same as having an effective security strategy in place.

We were subsequently brought in to:

• Manage the enforcement process

• Remove unauthorised occupants

• Properly secure the site going forward

  
  

Since then, the security model has been completely restructured. The result?

The building has remained secure for the past two years - and, importantly, the overall cost of maintaining that security has reduced. That is often the part people don’t anticipate.

Stronger security does not necessarily mean higher expenditure.

More often, it comes down to having the right structure, the right oversight, and the right approach from the outset.
