Sparta Guard sends SIA-licensed, DBS-checked officers across the Square Mile, from Bank and Moorgate to Liverpool Street and Fleet Street, and a guard is usually on site within the hour. Book on WhatsApp, day or night, with no contract.
The City of London is the capital’s financial district, and it runs to a rhythm of its own. Streets packed with office workers on weekdays go quiet in the evenings and at weekends. That pattern shapes the security work.
When the working week ends, much of the City empties. For a building owner or occupier, that means fewer people noticing a forced door, a tripped alarm or someone sleeping in a loading bay. Common out-of-hours bookings include:
The City of London has its own police force. Our officers are not police, have the same legal powers as any member of the public, and never replace a 999 call.
| Need | What to book |
|---|---|
| Reception or floor cover | Office security |

A server migration runs all weekend with the building otherwise empty. One guard covers the entrance from Friday night to Sunday evening.
A black-tie dinner runs until midnight. Two suited officers manage arrivals and see guests safely away.
An empty office floor shows signs of attempted entry. A responder checks the building and an officer covers the next three nights.

Yes. Message us with the address, the out-of-hours entrance and the times, for example Friday 6pm to Monday 7am. Officers can work in shifts to cover a full weekend, and there is no contract. Tell us who holds the keys and how the guard should reach you.
A guard is usually on site within the hour across Central London, including the City. Licensed officers are alerted as soon as you message, and you get updates on WhatsApp as the job is accepted and they travel to you. Out-of-hours jobs in the City follow the same process.
Yes. Officers can manage arrivals and the guest list, watch cloakrooms and valuables, and help guests leave calmly at the end of the night. Tell us the dress code, as many City events are black tie, plus the arrival and carriages times.
Yes. You can book a static guard, regular patrols or visits with photo reports while a building or floor is empty. Officers check doors, windows, alarms and signs of entry, and report anything that needs a locksmith, contractor or the police.
Every guard holds a current SIA licence and is DBS-checked, with identity and compliance checked before their first job. You can check any licence on the SIA’s public register. Sparta Guard is a Bark Elite Verified supplier, with no contracts and no call centre.
