Ever wonder why a quote for a smart security system can swing from a few hundred pounds to over a thousand? Most people just look at the monthly fee and forget the hidden expenses that pop up later. This guide breaks down every cost you’ll face, so you can put together a realistic budget before you sign any contract.
First up, the hardware. A basic kit with a door sensor, motion detector and a single camera usually starts around £150‑£250. Want more coverage? Adding extra cameras, glass‑break sensors or smart locks pushes the price to £400‑£600. Brand matters too – premium names like ADT or Vivint charge higher retail prices, while DIY brands such as Ring or Nest keep the entry point lower.
Installation is the next big line item. If you’re comfortable wiring a doorbell and mounting a few cameras yourself, you can save £100‑£200. Professional install services typically cost £80‑£150 per hour, plus any travel fees, and most companies set a minimum charge of about £200. Some providers bundle installation into the equipment price, so read the fine print before you assume you’ll need a separate fee.
Don’t forget the little things: mounting brackets, extra wiring, and sometimes a dedicated power transformer for video doorbells. Those add another £20‑£50 and are often overlooked until the installer shows up.
Monthly monitoring is where the real long‑term cost lives. Basic cloud storage and 24/7 police dispatch can run £10‑£20 per month for DIY brands. Fully managed services with professional response teams typically charge £30‑£45 per month. Look out for tiered plans – the cheapest tier might only store footage for 24 hours, while a premium tier with unlimited storage can add another £10‑£15.
Many companies throw in “optional extras” that attract extra charges. These include video‑verification for alarms, home automation integrations, and insurance discounts. Each add‑on can be £5‑£10 a month, and they stack quickly if you want a fully connected home.
Finally, check the contract length. A 12‑month lock‑in often includes a discounted monthly rate, but breaking it early can trigger a £200‑£300 early termination fee. Some providers now offer month‑to‑month plans with a slightly higher monthly rate but no exit penalty, which is worth considering if you like flexibility.
Bottom line: a fully equipped smart security system for a typical UK house costs roughly £300‑£500 upfront, plus £20‑£45 each month for monitoring and cloud storage. Adding extra cameras, professional installation and premium monitoring can push the total to £1,000‑£1,500 in the first year, then settle at £40‑£80 per month.
Use this breakdown to compare quotes, ask providers to itemise every charge and avoid surprises later. With a clear picture of one‑time and ongoing costs, you can pick a system that fits your budget and still gives you peace of mind.
