Register key holders for your burglar alarm

If you have a burglar alarm, you should: 

  • make sure it has a 20-minute working cut-out device
  • register the details of at least 2 people with us who have keys to your property and can turn off or reset your alarm

You could get a fine if your alarm causes a noise nuisance. Read more about how we can deal with noise nuisances on GOV.UK.

Who can be a key holder 

This can be a person or company. They should know how to: 

  • use your alarm system
  • contact your alarm company if needed
  • let us in to your property so we can deal with the alarm 

They should know that they may be contacted at any time of the day or night. 

Ideally, they should live within 20 minutes of your property.

What happens when the alarm sounds 

When we get a burglar alarm noise complaint, we try to contact the key holders. 

They should let the police in to check for a break-in and either, turn off or reset the alarm or contact your alarm company. 

If a key holder cannot help, we’ll check if we can disable it at the sounder box on the outside wall. We may need to break into the property to disconnect the alarm.  

If we had to break in, we’ll secure the property and change the locks if necessary. 

We'll let the police know so they can explain what happened and why we accessed your property.
