Brighton's mix of Regency terraces, 1930s semis in Woodingdean and Patcham, and flats converted from old townhouses in Kemptown means security work here isn't a one-size-fits-all job. A bay-fronted house on Marine Parade needs different sensor placement to a ground-floor flat off the London Road with a shared side passage, and installers who know the area will already have a feel for which streets see more opportunist break-ins versus which need discreet systems that don't clash with listed building rules. Sloped gardens around Hollingdean and the tight rear access on many Hanover terraces also affect where cameras and door contacts actually make sense, so local knowledge counts for something before a single cable gets run.
The businesses featured here come from public business listings, 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 read through each firm's homepage to check that alarm and security installation is genuinely their main line of work, which is what keeps general electricians or unrelated tradespeople off this page. Listings flagged as permanently closed are stripped out automatically. Where you spot 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. Businesses without the badge haven't been through that process with us, so it's worth doing your own checks before booking anything.
Before you commit, ask to see proof of any relevant accreditation and, if the job involves monitored alarms, confirm the system will meet the standard your insurer expects, since some policies specify BS 8243 or similar. Ask what happens after installation too: is there a maintenance contract, and what's the call-out charge if a sensor fails at 2am? Get written quotes from at least two or three installers rather than taking the first price, since costs for what sounds like the same job can vary by a few hundred pounds depending on equipment brand and whether it's wired or wireless. A face-to-face survey beats a phone quote every time, because it's the only way to spot access issues or wiring runs that change the price.
How We Select & Rate The Best Alarm & Security Installers in Brighton

How much does an alarm & security installers cost in Brighton?
A basic wireless burglar alarm for a two or three-bedroom terrace in areas like Fiveways or Preston Park typically runs from around £250 to £500 fitted, while a monitored system with keypad and app control can push past £800 depending on the number of sensors. CCTV setups vary hugely: a couple of cameras covering the front and back of a flat might cost £300 to £600, whereas a full multi-camera system for a larger property or small business could be £1,000 to £2,500 or more. Get two or three quotes, since equipment brand, wiring type and ongoing monitoring fees all shift the price.
Do I need planning permission to fit CCTV or an alarm box in Brighton?
Most domestic alarm boxes and CCTV cameras don't need planning permission, but if you're in a conservation area, which covers large parts of Kemptown, Hanover and the North Laine, or your building is listed, there can be restrictions on fixing anything to the exterior. Check with Brighton & Hove City Council's planning department if you're unsure, and mention it to your installer before they quote, as it might affect where equipment can go.
Wired or wireless alarm system, which is better for my home?
Wireless systems suit most Brighton flats and terraces because there's no need to chase cables through walls, which matters if you're renting or don't want to disturb original plasterwork in a Regency property. Wired systems are generally more reliable long-term and harder to jam, so they're worth considering for larger detached houses in areas like Withdean or Patcham where you're covering more ground. Ask your installer to explain the trade-offs for your specific property rather than assuming one is automatically better.
Will a monitored alarm reduce my home insurance premium?
Some insurers offer a discount for a monitored alarm meeting a recognised standard, though it's not guaranteed and varies by provider. Check with your insurer before booking to see exactly what they require, since installing the wrong grade of system won't help your premium at all. Keep the installation certificate and any compliance paperwork, as insurers often ask for proof after a claim.
How long does it take to install a burglar alarm or CCTV system?
A standard wireless alarm in a typical Brighton terrace usually takes half a day to a full day, depending on how many sensors and doors need covering. CCTV installation timing depends on the number of cameras and whether cabling needs running through lofts or under eaves; expect a full day for a modest domestic setup, longer for commercial premises. Ask for a time estimate upfront so you can plan around it.
What should I check before choosing an alarm or security installer in Brighton?
Ask to see evidence of relevant trade accreditation and current public liability insurance, and don't just take their word for it, ask for copies or policy numbers you can verify. Look at how long they've been trading and read a spread of recent customer reviews, not just the top few. Get a written quote that itemises equipment and labour separately, and ask what the warranty covers and for how long. If a system needs monitoring, confirm who the monitoring station is and what the ongoing fee will be, since that's an easy detail to gloss over at quote stage.
