Cancel Adt: The Right Way
How to cancel ADT security in australia and protect your rights
What ADT security is and why you might want to leave
ADT is a monitored security and smart-home service provider offering alarm monitoring, video surveillance and professional response for Australian homes and businesses. The service combines professionally installed systems with 24/7 monitoring centres, app-based alerts and optional video verification. Most customers sign up for peace of mind, but circumstances change: you move house, find a better provider, or the contract becomes unaffordable.
If you're thinking about cancelling ADT, you're not alone. At Stopee, we help thousands of Australians every month exit security contracts that no longer serve them. The key to a smooth exit is understanding your contract terms, your legal rights and the exact steps ADT requires you to follow.
ADT's service offerings in australia
ADT operates three main service categories in the Australian market. DIY monitoring plans offer flexible month-to-month terms with no long-term commitment. Professional packages, typically sold through installers, bundle equipment installation with monitored alarm services under fixed-term agreements (commonly 36 months). Camera-only plans provide cloud recording and alert services without traditional alarm monitoring.
Pricing starts from approximately A$32.90 per month for entry-level monitoring, though professionally installed packages often range between A$36 and A$69 monthly depending on features and bundled equipment. The contract length and cancellation rules depend entirely on which product you purchased and how it was sold to you.
Common reasons customers cancel ADT
You might cancel because you've relocated and no longer need monitoring at your old address. Some customers find competitors offer better features at lower cost. Others discover they're locked into a 36-month contract and want to explore other options. If you're in any of these situations, Stopee's guides can help you navigate the cancellation process with confidence.
ADT's subscription plans and pricing snapshot
Your cancellation options depend directly on which plan you're paying for and when your contract expires.
| Plan type | Monthly cost | Contract term | Flexibility |
|---|---|---|---|
| DIY full monitoring (recommended for flexibility) | From A$32.90/month | Month-to-month | Cancel anytime with notice |
| Professional monitored package | A$36-A$69/month | 36 months (typical) | Early termination fees apply |
| Camera-only monitoring | Variable | Month-to-month or fixed | Check your agreement |
Why contract type matters for your cancellation
If you're on a month-to-month DIY plan, you can typically cancel with 30 days' written notice and face no penalty. If you signed a professional package with a fixed 36-month term, you may owe an early termination fee equal to the remaining contract value if you cancel before the end date. This distinction is critical: it determines whether you'll exit free and clear or face unexpected charges.
Stopee recommends checking your original contract or account documents immediately to confirm your plan type and contract expiry date. Many customers discover they're further through their commitment than they realised, which can change the cost-benefit analysis of cancellation.
Understanding your consumer rights under australian law
Australian Consumer Law protects you even when you're cancelling a security contract.
What australian consumer law says about cancellations
The Australian Consumer Law, enforced by the Australian Competition and Consumer Commission (ACCC), gives you cooling-off rights for certain contracts. If ADT approached you by telephone, email or door-to-door (unsolicited consumer agreements), you have 10 business days to cancel without penalty, even if you're within a fixed term. This is a powerful protection that Stopee sees many customers underestimate.
Additionally, if ADT misrepresented the service, failed to install it properly or breached your contract, you may have grounds to cancel and claim a refund regardless of the contract length. Australian Consumer Law prohibits unfair contract terms, meaning any clause that prevents you cancelling in genuine hardship circumstances may be unenforceable.
What to do if ADT refuses your cancellation request
If ADT claims you can't cancel and you believe you have legal grounds, escalate to the ACCC. The ACCC has authority to investigate unfair contract terms and can force companies to refund customers or waive early termination fees. Stopee users have successfully appealed refused cancellations by citing the cooling-off rules or ACCC precedents in writing.
Document everything: your original contract, all emails from ADT, your cancellation request and any response. If ADT demands payment you believe is unfair, lodge a complaint with the ACCC at accc.gov.au before paying. This creates a formal record that strengthens your position.
How to cancel ADT: your step-by-step guide
ADT does not allow online cancellations for security reasons, so you must use phone, mail or in-person contact to exit your account.
Cancelling ADT by telephone
The fastest way to cancel is by phone, provided you document the call.
- Call ADT's Australian customer service line. Have your account number, full name and registered address ready.
- Ask to speak with an account manager or cancellation specialist, not general support.
- State clearly: "I want to cancel my ADT monitoring service effective [your preferred date]."
- Choose a date at least 30 days away to satisfy notice periods on most plans.
- Listen carefully as ADT informs you of any early termination fees and final billing amount.
- Pro tip: Ask the agent to email you a written summary of the cancellation terms, including the effective date and any final charges. If they refuse, that's a red flag - request they put it in writing via post instead.
- Confirm your final billing date and whether ADT will issue a refund or credit for unused monitoring.
- If you've prepaid in advance or paid for a month you won't use, ask for pro rata refund calculation.
- Get the agent's name and call reference number. Ask them to confirm the cancellation date and any fees in writing by email within 2 business days.
- Warning: Don't hang up until you have this reference number. It's your proof the cancellation was requested.
- Follow up in writing (email or post) within 24 hours with your own cancellation confirmation letter, referencing the call reference number and the date you want the service to end.
Cancelling ADT by post
If you prefer a formal paper trail or live in a remote area, send a registered letter to ADT's Australian address.
- Prepare a cancellation letter on plain paper or your letterhead including:
- Your full name as it appears on the account.
- Your ADT account number.
- Your registered service address.
- Your requested cancellation date (at least 30 days from the date you post the letter).
- A clear statement: "I hereby request cancellation of my ADT monitoring service, effective [date]."
- Your current contact phone number and email address.
- Send the letter via Australia Post Registered Mail with tracking. This creates proof of postage and delivery.
- Pro tip: Keep the tracking receipt and photos of the envelope before posting.
- Address the letter to: ADT Security Australia, PO Box [check ADT's current postal address on their website or account documents].
- Warning: Postal addresses can change. Verify the correct PO Box before posting to avoid the letter being returned undelivered.
- Allow 10-15 business days for ADT to process the cancellation. Follow up by phone if you don't receive written confirmation within this window.
Cancelling in person at an ADT office
Some ADT offices accept in-person cancellations, though this is less common for residential accounts. If you choose this method, bring your account number, proof of identity and your request in writing. Ask for a signed receipt confirming the cancellation date and any fees discussed.
What to expect after you cancel ADT
Cancellation doesn't end overnight - there are steps you should take to protect yourself.
Final billing and refunds
ADT typically processes final billing within 7-14 days of your cancellation date. You'll receive a final invoice showing any remaining balance, early termination fees (if applicable) and pro rata credit for unused monitoring days. If you've prepaid or overpaid, ADT should issue a refund within 21 days. If payment is due, ADT may withhold the refund until you settle the amount.
Pro tip: Request a pro rata refund calculation in writing during your cancellation call. This gives you a benchmark to check against your final invoice. If the final invoice shows different charges, contact Stopee for guidance before paying.
Monitoring system and equipment removal
If ADT installed monitoring equipment (sensors, keypad, alarm panel), clarify during cancellation whether you own the equipment or must return it. Most rental arrangements allow you to keep the equipment; some contracts require removal. If removal is required, ADT usually schedules this within 30 days at no charge. Don't uninstall equipment yourself unless ADT explicitly permits it.
If the system remains in your home after cancellation, inform ADT in writing so they deactivate it remotely. A live system belonging to a former customer can cause false alarm triggers and confusion for future owners or tenants.
Redirecting your monitoring to another provider
If you're switching to a new security provider rather than cancelling entirely, coordinate the transition carefully. Inform your new provider of your ADT cancellation date so they can activate monitoring on the same day or within 24 hours. A gap in monitoring coverage exposes your property, so plan this overlap in advance. Stopee recommends confirming activation dates with both providers in writing before your ADT service ends.
Common cancellation mistakes to avoid
Cancellation conversations can feel stressful, and mistakes cost money or extend your contract unintentionally.
Mistake 1: not documenting your cancellation request
The biggest error customers make is cancelling by phone without getting written confirmation. ADT may claim weeks later that no cancellation was requested, and without proof you're stuck. Always follow a phone call with an email or letter restating the cancellation and referencing the call reference number. This forces ADT to acknowledge your request in writing.
Mistake 2: accepting a contract renewal during cancellation
Some ADT agents offer discounts or new features as a last-ditch effort to retain you. Don't accept verbal agreements to extend, modify or renew your contract during a cancellation call. If ADT offers a deal, ask them to send it in writing and give yourself 48 hours to decide. Otherwise, end the call, cancel as planned and evaluate the offer separately. Most "retention offers" disappear once you've formally cancelled anyway.
Mistake 3: ignoring early termination fees
If you're locked into a 36-month contract and cancel after 18 months, ADT will charge you for the remaining 18 months of service. This fee is usually non-negotiable unless you have legal grounds to dispute it. Before you decide to cancel, calculate the early termination fee and weigh it against the value of your new arrangement. Sometimes it's cheaper to stay until the contract naturally expires.
Mistake 4: assuming "30 days' notice" means 30 calendar days
Most ADT contracts require 30 business days' notice, not 30 calendar days. Business days exclude weekends and public holidays. If you call on a Friday afternoon, your notice period starts the following Monday. Calculate 30 business days carefully or ask ADT to confirm the exact effective cancellation date in writing. Miscounting can inadvertently extend your billing by another month.
Mistake 5: not checking for cooling-off rights
If your ADT contract was sold to you unsolicited (door-to-door, phone sales), you have 10 business days to withdraw without penalty, even within a fixed term. Stopee users often overlook this right because ADT doesn't advertise it. Pull out your contract documents and look for the sales channel. If it says "sold via telemarketing" or doesn't specify a physical store visit, you likely have cooling-off protection. Invoke it in writing immediately if you're within 10 business days.
Reviewing your cancellation checklist
Before you consider your cancellation complete, run through this final checklist to avoid surprises.
| Action | Completed? | Notes |
|---|---|---|
| Confirm your plan type and contract end date | ☐ | DIY or professional? Fixed term or month-to-month? |
| Calculate early termination fees (if applicable) | ☐ | Get a written fee quote from ADT before confirming cancellation. |
| Submit your cancellation request (phone or post) | ☐ | Record the call reference number or keep the registered post receipt. |
| Follow up in writing within 24 hours | ☐ | Email or posted letter restating the cancellation date requested. |
| Receive written cancellation confirmation from ADT | ☐ | Should arrive within 10 business days. Follow up if it doesn't. |
| Arrange for equipment removal or notify ADT to deactivate remotely | ☐ | Clarify ownership and removal responsibility in writing. |
Comparing ADT with alternative security providers in australia
If you're cancelling because you've found a better option, you're in good company. Stopee helps customers evaluate the trade-offs between providers so you make an informed switch.
| Provider | Typical cost | Contract type | Cancellation ease |
|---|---|---|---|
| ADT (current) | From A$32.90/month (DIY) or A$36-A$69/month (professional) | Flexible DIY or 36-month professional packages | Phone or post; no online option |
| Alternative providers (e.g. Chubb, Securitronics) | Varies A$25-A$60/month | Often month-to-month or shorter terms | Usually faster and simpler |
| Self-monitoring apps (e.g. DIY brands) | A$10-A$25/month | Month-to-month, no long commitment | Cancel anytime online |
Before you switch, confirm your new provider's activation date overlaps with ADT's cancellation date. Also check whether your new system is compatible with existing equipment if you're keeping ADT's hardware.
