When your alarm goes off and you are miles away, Sparta Guard's alarm response in London sends an SIA-licensed, DBS-checked responder to check the property for you. Across Central London, a responder is usually on site within the hour. They check every entry point, tell you what they find and send photos on WhatsApp, with no contract needed.
The responder’s job is to find out, safely, whether it is a false alarm, a fault or a real attempt to get in.
If there are signs someone is inside, the responder does not go in alone. They call 999, keep watch from a safe position and update you while the police are on the way.
Many people expect the police to attend when an alarm sounds. In practice, police forces follow the National Police Chiefs’ Council policy on alarms:
| Type of alarm | Typical police response |
|---|---|
| Audible only (“bells only”) | No attendance unless there is other evidence a crime is in progress, such as a witness |
| Monitored, with police response registered | Police may be called by the monitoring centre, depending on the force’s rules and the alarm’s false alarm history |
| Monitored, keyholder response only | The monitoring centre calls you or your keyholders, not the police |
So someone has to go and look. Check your insurance terms too, as some insurers expect a keyholder to attend within a set time.
You can book alarm response in two ways.
You message us and a responder checks the outside. You arrange access if the inside needs checking.
We keep your details, access instructions and alarm code on file, so a responder can check inside straight away. Holding keys to your premises under contract is licensable work, and needs an SIA Key Holding licence.
For properties that stay empty for weeks, see vacant property security. If you want regular visits rather than a response to each activation, look at mobile security patrols.
Use WhatsApp, Facebook Messenger or the Sparta Guard app, as explained in how on-demand security works.
Tell us which zone triggered, if you know, and whether anyone should be on site.
A key safe code, a neighbour or keys held by us.
The responder checks the property and reports back on WhatsApp with photos.
If the responder finds a break-in, we can arrange emergency security guards to stay until the property is made secure.
Their monitoring company calls at midnight about a back door sensor in their Fulham home. A responder finds the door locked and a cat flap rattling in the wind.
The alarm activates at 4am after close. A responder finds a forced rear door, calls the police and stays until a locksmith arrives.
The price depends on the time of day, whether the responder needs to go inside and whether you register your property in advance. If you own several properties or a business with frequent activations, ask about membership plans.
Across Central London, a responder is usually on site within the hour of your message. Outside Central London, tell us the address when you message and we will confirm straight away whether we can attend and roughly how long it will take.
No. A responder can check the outside of the property without keys, and many alarm activations can be resolved that way. If the inside needs checking, you can use a key safe or a neighbour, or ask about registering your property with us in advance.
No. If there are signs someone is inside, the responder stays outside in a safe position, calls 999 and keeps you updated. Security officers have the same legal powers as any member of the public, so their role is to observe, report and support the police.
If you share the alarm code and give access, the responder can silence and reset the panel and note which zone triggered it. They cannot repair faults, so if the same zone keeps activating, speak to your alarm installer.
No. A monitoring company watches your alarm signals and calls you or your keyholders. Sparta Guard is the person who goes and checks. You can use both: the monitoring centre alerts you, and you message us to send a responder.
Message us now and local SIA-licensed responders are alerted straight away.
Simple. Discreet. Always local.
