Sparta Guard provides 24 hour security in London in two ways: SIA-licensed, DBS-checked guards who cover your site around the clock in planned shifts, and a booking line that never closes. Message us at 3am on a Sunday and local guards are alerted straight away. Across Central London, a guard is usually on site within the hour.
People looking for 24/7 security usually mean one of two things. We do both.
You can book at any hour through WhatsApp, Facebook Messenger or the Sparta Guard app. There is no out-of-hours voicemail.
A guard is present at your premises every hour of the day and night, for a weekend, a fortnight or until a problem is fixed.
No single guard works around the clock. Continuous cover means guards working in shifts, with a proper handover each time. These are common patterns:
| Pattern | Typical hours | Suits |
|---|---|---|
| Two 12-hour shifts | 07:00 to 19:00, then 19:00 to 07:00 | Construction sites, empty buildings, sites after a break-in |
| Three 8-hour shifts | Early, late and night | Busy receptions or sites where alertness matters most |
| Nights only | 18:00 or 19:00 to 06:00 or 07:00 | Sites staffed by day but empty at night |
| Weekend blocks | Friday evening to Monday morning | Offices, shops and sites closed at the weekend |
| Bank holiday cover | The full closure period | Sites shut for Christmas, Easter or long weekends |
Gaps often open at shift change. At each handover, the outgoing guard should:

If you only need an urgent presence tonight, start with emergency security guards and extend if needed.

The address, the start time, how long you need continuous cover and what the guards will protect.
Local SIA-licensed guards are alerted for each shift, and you get updates as they are accepted.
Each shift is briefed by the one before, and you hear from us on WhatsApp if anything happens.
A site closes for Christmas with materials on the ground floor. Guards work 12-hour day and night shifts for ten days.
A ram raid leaves the shopfront boarded for four days. Guards cover the unit around the clock until the glazing is replaced.
The concierge guard at a residential block is signed off for a fortnight. Day and night guards keep the lobby covered.
Continuous cover is priced by the hours booked, so the total depends on how many days you need and when they fall. We confirm the price before any shift starts.
Our guards cover Central London, including:

Yes. Booking is open 24 hours a day, seven days a week, through WhatsApp, Facebook Messenger or the Sparta Guard app. Local SIA-licensed guards are alerted as soon as you message, and across Central London a guard is usually on site within the hour.
No. Round-the-clock cover is split into shifts, commonly two 12-hour shifts, with a handover each time. That keeps guards alert through the night. Each handover covers keys, alarm codes, the occurrence log and anything that needs watching, so nothing is lost between shifts.
As long as you need it, from one night and day to several weeks. There is no contract or minimum term, so you can stop when repairs are done or the site reopens. For long periods, tell us early so shifts can be planned.
No. With 24-hour security, a guard stays on your site the whole time. A patrol or property check visits at intervals and moves on. If your site only needs checking once or twice a day, scheduled checks may be the more practical choice.
Usually, yes. Message us in the same chat to extend, shorten or switch from continuous cover to nights only, for example once a broken door is repaired. Give as much notice as you can so the next shift can be adjusted.
