If you’re thinking about signing up with ADT, the first thing you’ll ask is “how much will it cost me each month?” The answer isn’t a single number – it depends on the package, equipment, and any add‑ons you choose. Below we break down the typical price points you’ll see on a UK bill and what you actually pay for.
Most ADT plans start with a base monitoring fee. In 2025 the standard monitoring charge ranges from £24 to £35 per month for a basic alarm system with 24/7 police dispatch. This fee covers the centre that watches your sensors, the response team, and the software that sends alerts to your phone.
On top of the monitoring fee, you’ll see an equipment rental charge. ADT usually rents the panel, motion sensors, door/window contacts, and any cameras you add. Rental costs are typically £8‑£12 per month per device bundle, but many customers opt to buy the gear outright to avoid ongoing rentals.
Installation is another line item. ADT offers free professional install on many contracts, but some promotions require a £99‑£149 one‑time fee. If you choose a self‑install kit, the charge drops to under £50.
Don’t forget the optional extras. Smart home integration, video doorbells, and advanced motion sensors can add £5‑£15 each month. These features are nice to have, but they can quickly push a modest bill over £60.
Finally, look at the contract length. ADT commonly asks for a 36‑month commitment. Early‑termination fees can be as high as £250, so make sure you’re comfortable with the duration before you sign.
First, ask for a “monitor‑only” plan. Some customers already have their own sensors and just need the monitoring service. Dropping the equipment rental can shave $15‑$20 off the monthly total.
Second, compare the buy‑versus‑rent option. Buying a panel and sensors once (usually £200‑£350 total) eliminates the recurring rental charge and can pay for itself in under two years.
Third, bundle services. ADT often runs promotions where adding a camera or doorbell reduces the per‑device cost. Check the latest deals on their website or call a sales rep to negotiate.
Fourth, review your contract before renewal. Many users stay on an outdated plan that costs more than a newer, streamlined package. A quick call can reset your fees to the current standard rates.
Lastly, keep an eye on hidden fees like “maintenance” or “software updates.” Ask the rep to write down any optional charges before you agree to the contract.
In short, the average ADT monthly cost sits between £30 and £55 for a typical home setup. Your exact bill will depend on the equipment you need, any smart add‑ons, and how long you commit. By understanding each line item and negotiating smartly, you can keep your security budget under control while still getting 24/7 protection.
