Aberdeen's mix of granite tenements, new-build estates out towards Bridge of Don and Countesswells, and older detached houses in Cults or Milltimber all throw up different security jobs. A stone-built flat off Union Grove might just need a wireless alarm and a smart video doorbell, while a farmhouse out near Peterculter or Westhill could need perimeter sensors, CCTV covering a long driveway, and a system that copes with patchy broadband for monitoring. Granite walls are notoriously thick, which matters for anyone fitting wireless sensors, and areas with limited mobile signal need alarms with a solid backup connection. Local installers who know the housing stock and the quirks of certain postcodes tend to spec systems more sensibly than someone working from a generic template.
The businesses listed here are pulled from public business listings and ranked mainly by 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 slipping onto the page. Listings flagged as permanently closed get removed automatically as part of that process. Where you see a Trust Verified badge, that business has gone further and passed our full verification, covering trade qualifications and accreditations, public liability insurance, trading history, customer review history, and registered company information; our How We Verify page sets out exactly what that involves. For any business without that badge, those checks haven't been done by us, so it's on you to ask the right questions before booking.
Before signing up with any installer, ask to see their accreditation (NSI or SSAIB certification is the standard to look for on monitored alarm systems), confirm what happens if the alarm triggers out of hours, and check whether monitoring is included in the price or billed separately. Get written confirmation of the equipment being fitted, whether it's wired or wireless, and what the warranty covers. It's worth getting two or three quotes, since prices for a similar four-bed house can vary by a few hundred pounds depending on the kit specified and whether it's linked to a monitoring centre. Ask neighbours or check reviews for how the installer handles call-outs and false alarms too, since that's often where the real difference shows up.
How We Select & Rate The Best Alarm & Security Installers in Aberdeen
Ranking is based on review rating and review count from public business listings, with a small lift for businesses showing a working website and phone number. We check each business's homepage to confirm alarm and security installation work is what they primarily offer, which keeps unrelated trades off the page. Listings marked as permanently closed are removed automatically. Businesses displaying 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; see our How We Verify page for the full list. Other businesses on this page have not been independently verified by us, and their inclusion isn't an endorsement. Always carry out your own checks before hiring.

How much does an alarm and security installer cost in Aberdeen?
A basic wireless intruder alarm for a two or three-bed flat typically runs from around £250 to £500 fitted, while a fuller system with monitoring, extra sensors and a couple of CCTV cameras for a detached house can reach £800 to £1,500. Monitoring subscriptions usually add £15 to £30 a month if you want a monitoring centre alerting you or the police rather than just a local siren. Prices vary depending on the number of doors and windows covered, whether you want smart app control, and how much cabling is needed in an older stone property. Getting two or three quotes is normal practice here, and worth doing since the spread between installers can be a few hundred pounds.
Do I need planning permission for CCTV cameras in Aberdeen?
For most homeowners, no. Domestic CCTV covering your own property doesn't usually need planning permission, but if a camera captures a significant amount of a neighbour's garden or a public pavement, you're expected to be sensible about angling it and may need to consider data protection rules. Flats in shared tenement stairwells sometimes need factor or landlord approval before fitting anything to communal walls, so check that first if you're in a shared close.
How long does it take to fit a house alarm?
A straightforward wireless system in a standard semi or terrace usually takes half a day to a full day. Wired systems, or houses needing extra sensors, external sirens and CCTV integration, can take one to two days. Older granite properties sometimes take longer if cabling has to be routed through solid stone walls rather than stud partitions, so ask your installer to be upfront about timescales before work starts.
Will an alarm system work if my broadband or mobile signal drops out?
A decent monitored system should have a backup route, either a SIM card fallback or a dual-path setup using both broadband and mobile network. This matters more in rural spots around Aberdeenshire's edges, like parts of Kingswells or further out towards Dunecht, where signal can be patchy. Ask your installer specifically how the system behaves if the internet goes down, since a cheap system with no backup is only as reliable as your router.
Is it worth linking my alarm to a monitoring centre?
It depends on how often you're away from the property and how quickly you want a response. A monitored system means a monitoring centre gets an alert and can contact keyholders or emergency services, which suits people who travel for work or have holiday homes. If you're home most of the time, a self-monitored system with app alerts to your phone might be enough and saves the monthly fee. Weigh up the ongoing cost against how much peace of mind you actually need.
How do I choose between alarm and security installers in Aberdeen?
Check whether the installer holds NSI or SSAIB accreditation, particularly if you want a monitored system, since insurers sometimes ask for this. Ask to see examples of similar jobs they've done, ideally in a similar property type to yours, and read through recent customer reviews rather than just the star rating. Confirm public liability insurance is in place, ask what the warranty covers and for how long, and get at least two written quotes before deciding. If a badge on this page shows a business has been through fuller verification, that's a useful starting point, but for anyone without it, doing these checks yourself before booking is sensible.
