How Much Does Installing a Security System Actually Cost?

When you start thinking about adding cameras, alarms or a video doorbell, the first thing that pops into your head is the price tag. It’s easy to get scared by big numbers, but the real cost depends on a few simple things: the type of equipment, how many devices you need, and whether you do the work yourself or hire a pro.

What Drives the Installation Cost?

Even before you pick a brand, ask yourself these three questions:

• Coverage area: Are you protecting a small flat or a large house with a garden?
• Power source: Do you want wired gear that needs an electrician, or wireless gear that runs on batteries?
• Monitoring style: Will you watch the feeds on your phone yourself, or pay for a 24/7 monitoring service?

Answering these helps you narrow down the equipment list and gives you a realistic budget.

Typical Price Ranges for Common Gear

CCTV cameras: A basic indoor Wi‑Fi camera starts at about £30‑£50. Outdoor bullet cameras with night vision run £80‑£150 each. Professional-grade PTZ units can be £250‑£500. Installation fees vary – a DIY mount might be free, while a certified installer could charge £80‑£150 per camera.

Video doorbells: The popular smart doorbells cost £100‑£200 for the unit. If you need a licensed electrician to wire it to an existing doorbell circuit, expect an extra £80‑£120.

Alarm systems: A starter kit with a control panel, a few motion sensors and doors/window contacts usually sits around £200‑£400. Professional wiring and a monitoring subscription add another £100‑£300.

Don’t forget hidden costs like drilling, conduit, or extra power adapters. A good rule of thumb is to add a 10‑15% buffer for unexpected expenses.

Now that you know the ballpark numbers, here are three practical ways to keep the installation cost down.

• Go wireless where you can: Wireless cameras and doorbells avoid the need for an electrician. Just make sure the Wi‑Fi signal reaches the spot.
• Bundle equipment: Many suppliers offer package deals that shave 10‑20% off the total.
• Do part of the work yourself: Mounting a camera or swapping a doorbell battery is easy for most DIYers. Leave only the electrical connections to a pro.

Finally, remember that the cheapest option isn’t always the best. A low‑cost camera with poor night vision may force you to replace it sooner, costing you more in the long run. Look for a balance between upfront price and long‑term reliability.

If you’re still unsure, a quick free quote from a local security installer can give you a tailored cost estimate. Most companies will walk you through the options, point out any hidden fees, and suggest the most cost‑effective setup for your home.

Bottom line: installation cost isn’t a mystery. By understanding what you need, checking the gear prices, and planning the DIY vs. professional split, you can plan a security system that fits both your safety goals and your budget.
