Belfast throws up a real mix of housing when it comes to security work, from Victorian terraces in the Holylands and Ormeau area with dodgy old wiring, to new-build estates out towards Dundonald and Carryduff where everything's already ducted for smart systems. Older houses off the Lisburn Road or Antrim Road often need extra thought given to cable routing and where a control panel can actually go, while apartments in the Titanic Quarter or city centre tend to lean towards video doorbells and app-controlled systems rather than a traditional bell box on the wall. Rural fringes towards Lisburn or Newtownabbey bring their own issues too, with longer driveways and outbuildings that need separate coverage. A local installer who already knows these streets and estates will usually spot problems a stranger to the area might miss.
The businesses featured here are pulled from public business listings and ranked mainly on review rating and how many reviews they've built up, with a small lift given to those showing a working website and phone number. We check each business's homepage to confirm alarm and security installation is genuinely what they do day to day, which stops general electricians or unrelated tradespeople sneaking onto the page. Listings flagged as permanently closed get removed automatically. Where you spot a Trust Verified badge, that business has gone through our fuller check covering trade qualifications and accreditations, public liability insurance, trading history, customer review history and registered company information, and you can read exactly what that involves on our How We Verify page. Businesses without the badge haven't been through that process with us, so it's worth doing your own homework before you book anyone in.
Before signing off any work, ask to see evidence of relevant certifications for alarm installation and, if CCTV is involved, check they understand data protection rules around cameras pointing towards neighbours' property or shared paths. Get a written quote that spells out exactly what's included, whether that's a wired or wireless system, monitoring fees, and how many keypads or sensors you're getting for the price. It's worth asking how call-outs and false alarms are handled too, since some contracts charge extra. Getting two or three quotes is standard practice here and lets you compare not just price but how thoroughly each installer surveys your home before quoting.
How We Select & Rate The Best Alarm & Security Installers in Belfast
Ranking is based on review rating and review count from public business listings, with a small lift given to businesses showing a working website and phone number. We check each business's homepage to confirm alarm and security installation is their main line of work, which keeps unrelated trades off the page. Listings marked as permanently closed are removed automatically. Businesses carrying a Trust Verified badge have additionally passed our full verification covering trade qualifications and accreditations, public liability insurance, trading history, customer review history and registered company information, detailed on our How We Verify page. Other businesses listed have not been independently verified by us, and their inclusion isn't an endorsement, so do your own checks before hiring.
Recommended and Featured listings are paid placements, so a business's fee affects whether and where it appears. Every other listing is ranked on rating and review count from third-party business listings. How we rank & verify →

How much does an alarm system installation cost in Belfast?
A basic wired burglar alarm for a mid-terrace on streets like the Ormeau or Cregagh Road typically runs from around £350 to £600 fitted, while a wireless system with a few extra sensors can push that to £700 or more. CCTV setups vary hugely depending on camera count and whether you want remote viewing, with a two or three camera system often landing between £500 and £1,200. Bigger detached houses or anything needing monitoring contracts will cost more, and it's normal to get two or three quotes before deciding, since prices between installers can differ quite a bit for similar specifications.
Do I need planning permission for CCTV cameras at my house in Belfast?
Most domestic CCTV doesn't need planning permission as long as cameras are pointed at your own property and not capturing next door's garden or a shared entrance in detail. If you're in a listed building or conservation area, such as parts of the Malone Road, it's worth checking with Belfast City Council before fixing anything to the exterior. Your installer should also be able to advise on angling cameras sensibly to avoid disputes with neighbours.
Is a monitored alarm worth paying extra for?
A monitored system means a control room gets alerted if the alarm triggers and can contact you or the police, which suits people who travel a lot or run a business from home. It typically adds a monthly fee on top of installation, often somewhere between £15 and £30 depending on the provider. If you're rarely away and have neighbours who'd notice a bell ringing, a standard self-monitored system might be enough, so weigh up your own routine before committing to a contract.
How long does it take to install a burglar alarm or CCTV system?
A straightforward wireless alarm in an average three-bedroom semi can often be fitted in half a day. Wired systems take longer because of cable runs through walls and lofts, sometimes a full day or two depending on the house. CCTV installation timing depends on camera count and whether cabling needs to be hidden, but three or four cameras usually takes most of a day including setting up the app and recorder.
Can I get a smart alarm that works with my phone?
Yes, most installers in Belfast now fit smart systems as standard, letting you arm or disarm the alarm and check cameras through an app wherever you are. It's worth asking whether the system needs a strong broadband connection to work properly, since some rural properties on the outskirts of Belfast have patchier signal. Ask too what happens during a power cut or broadband outage, as some systems have battery backup and a mobile data fallback while cheaper ones don't.
How do I choose between alarm and security installers in Belfast?
Start by checking the installer's own reviews and asking to see photos of previous jobs similar to yours, whether that's a period terrace or a new-build. Ask directly about their qualifications and whether they hold public liability insurance, and request proof rather than taking it on trust. Get quotes from at least two or three installers so you can compare not just price but what's actually included, such as call-out terms and warranty length. If a Trust Verified badge appears on this page, that business has already been through a fuller check by us, but for anyone without it, doing this legwork yourself before booking is worth the time.
