How to Cancel Your Alarm Monitoring Service

Read the fine print.

First, you’ll need to review your contract with the company. This will give you an idea of the length, the scope of service, and other contingencies that may apply.

For example, if you’re calling to cancel your alarm monitoring service, you might need to wait a certain period before termination. Common monitoring contracts will require you to cancel as early as three months before your term ends. If you don’t, your subscription will renew automatically.

Here are some other things you should look for in your agreement:

  • Notification for termination
  • Term of agreement
  • Applicable penalties for early termination
  • Ownership of Equipment

Write your letter

After thoroughly reviewing the agreement, you can start writing your letter. Make sure to follow the proper letter structure and use formal salutations. When writing your letter, you also need to include important information such as:

  • Account number
  • When you want the service to end
  • Reason for cancellation, and so on.

Ask for an official confirmation.

Once you’ve sent in your letter, make sure to ask for official confirmation through email or in writing. This will ensure that your cancellation request has been approved.
