ADT Pricing: What You Really Pay for Home Security in 2025

When people ask about ADT pricing, a leading professional home security service in the UK with 24/7 monitoring and AI-driven alerts. Also known as ADT Pulse, it's one of the most recognized names in home security—but what you pay isn’t always obvious. Unlike buying a camera off Amazon, ADT bundles hardware, installation, and ongoing monitoring into one package. That means your monthly bill isn’t just for alarms—it’s for someone watching your home while you sleep, work, or vacation.

Most customers don’t realize professional monitoring, a service where trained operators respond to alarm triggers and contact emergency services is the core of what makes ADT different. It’s not just about the siren going off—it’s about a live person verifying a threat and calling the police before a burglar even gets inside. That’s why ADT’s pricing includes this service, even if you skip the fancy smart features. And if you’re comparing it to Ring or Arlo, remember: those systems often charge extra just to save video clips. ADT includes monitoring in its base plan, but you’ll still pay for equipment and installation upfront.

Then there’s the smart home security, a system that connects alarms, cameras, and sensors to a central hub you control from your phone. ADT’s 2025 systems integrate with Google Nest and Alexa, letting you arm your system with your voice or see who’s at the door without opening the app. But not everyone needs all that. Some just want a reliable alarm that won’t fail when the power goes out. ADT’s wired and hybrid options still hold up in outages, unlike purely wireless systems that go dark when WiFi drops.

Here’s the thing: ADT pricing varies by home size, location, and how many sensors you add. A basic setup might start around £30/month, but add cameras, glass break sensors, and smart locks, and you’re looking at £50+ before taxes. Installation fees? Often waived if you sign a 3-year contract—but read the fine print. Some deals lock you in with no early exit without penalties. And while competitors like Vivint offer similar features, ADT still leads in response times and customer support, according to recent consumer reports.

Don’t let marketing confuse you. ADT isn’t the cheapest, but it’s one of the few that still guarantees a live operator will respond when your alarm triggers. That’s worth something when every second counts. If you’ve got kids, pets, or a remote property, the peace of mind from real-time monitoring isn’t a luxury—it’s insurance.

Below, you’ll find real breakdowns of what ADT includes, how it stacks up against other systems, and what hidden costs people forget to ask about. No guesswork. Just facts from people who’ve been through it.
