How to Cancel an ADT Contract without Penalty

We answer common questions about canceling an ADT contract to help make the process smoother. We’ll show you what to look for and what to expect when it’s time to part ways with ADT.

Can you get out of an ADT contract?

Yes, you can cancel your ADT contract anytime by calling customer service at 800-238-2727. Whether you pay penalties or not depends on how many months you have left on your contract.

  • You can cancel in the first six months with no penalties thanks to the company’s money-back service guarantee, although ADT’s Terms and Conditions aren't clear on what qualifies as a refund-worthy cancellation reason.
  • After six months, you can cancel your contract by paying 75% of your remaining balance.

To start the cancellation process, call ADT or your ADT dealer.

Is there a fee to cancel ADT?

If you’ve had your ADT alarm system for longer than six months, you’ll pay 75% of the remaining balance on your contract. This is actually lower than many home security companies such as Brinks, Protect America, and Alder, which charge between 90% and 100% but have shorter trial periods.

In the table below, check out estimated termination fees you might pay at certain points in your ADT contract.

What is the ADT cancellation policy?

  • Customers pay 75% of remaining monthly charges when canceling early.
  • ADT has a 36-month contract (24 months in California).
  • There’s a six-month money-back service guarantee.

About ADT's six-month service guarantee

On the surface, ADT’s money-back guarantee looks like a pretty good deal. Still, it’s surprisingly vague on whether an ADT customer can cancel out of dissatisfaction or for reasons other than technical problems:

“Money back service guarantee only applies after ADT has made attempts to resolve a system related issue and has not been able to resolve that issue within the first 6 months of your contract. Equipment must be fully removed before a refund will be processed. Conditions preventing normal system operation cannot be caused by the customer.”1

Since ADT’s terms and conditions don’t refer to any other type of return policy other than a “system related issue,” we don’t advise getting an ADT system if you’re banking on the six-month guarantee.

Can I cancel my ADT service online?

No. ADT cancellation requires a customer service phone call to 800-238-2727. During the call, the customer service agent gives you instructions and may ask you to submit a written request. This call is the best time to ask if you’re getting a refund.

What happens when I cancel my ADT contract early?

You’ll pay the applicable termination fees (75% of remaining monthly charges), and ADT will send you a prepaid box with instructions on how to return your ADT equipment.

If you cancel in the first six months, you might get a refund to the payment method on your ADT account after ADT receives your equipment.

ADT doesn’t specify exactly what’s included in the refund, but it should cover equipment costs, installation fees, and monitoring fees.

What happens at the end of my ADT contract if I don’t cancel early?

After you fulfill your initial contract term, it automatically renews on a month-to-month basis until you cancel. There are no termination fees when you cancel a monthly contract.

In some cases, your contract might renew for a longer term, so it’s a good idea to check your copy for exact renewal details.
