Essential key holding and response services

across London

There are many reasons that a key holder might be called your premises outside of working hours. Normally it is due to an alarm being triggered, or emergency services having been called to the scene. They are there to assist authorities in gaining entrance to the building, as well as securing the property in the vent of damage of vandalism.

At Marpol Security, we provide key holding services for companies across the whole of London. This includes the City of London itself, as well as all 32 London boroughs. These highly-trained professionals deliver an effective service, being there to discharge their duties when you need them most.


As London’s leading provider of key holding services, we have much to offer companies in the capital. Here are some of the services we provide:

Triggered alarms

The most common reason for one of our keyholders to be called out is an alarm triggered on the premises. This will be picked up by our remote monitoring team, who will instruct our key holder to attend the site. Our key holders form part of our mobile patrol teams operating across London, meaning they can be at your premises within minutes.

Emergency call-outs

If an emergency takes place at your property outside of office hours, any emergency services personnel in attendance will have instructions to call our key holder. This covers a range of eventualities, including storm damage, fires, bomb threats and more. Our key holder will liaise with the emergency staff in attendance to reach a positive outcome.

Detailed reports

Whatever reason our key holders are called to you property, they will compile a detailed report explaining it. This report will include their own appraisal of the situation, together will any supplementary information from attendant police officers or other emergency service providers. These reports can help us to identify weaknesses in your current security set-up and recommended solutions for an improved service.
