Worthing's mix of Victorian terraces near the seafront, 1930s semis around Durrington and newer estates towards Goring means security needs vary street by street. A bay-fronted house off Chapel Road might need discreet wiring for a period property, while a modern build in Wick could already have ducting in place for smart alarm kits. Coastal salt air also plays havoc with external sirens and cameras over time, so installers who know the area tend to spec kit that holds up to Worthing's weather, not just whatever's cheapest on the shelf. Burglary patterns here often follow the tourist season too, with a rise in opportunist break-ins during summer when properties near the seafront are let out or left empty, so local knowledge genuinely helps.
The businesses featured on this page are drawn from public business listings and ranked by review rating and review count, with a small lift given to those showing a working website and phone number. We read each business's homepage to check that alarm and security installation is genuinely what they do day to day, which stops unrelated tradespeople slipping onto a list like this. Listings flagged as permanently closed are stripped out 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; our How We Verify page sets out exactly what that involves. Any business without the badge hasn't been through that process with us, so it's worth doing your own homework before booking.
Before you commit, ask to see proof of qualifications and, ideally, membership of a recognised body such as the NSI or SSAIB, since this can affect insurance discounts too. Get a written quote that specifies the number of sensors, control panel type, monitoring options and warranty period, not just a headline price. Ask whether the alarm is monitored or self-monitored via an app, and what happens if the broadband or mobile signal drops. It's sensible to get two or three quotes for anything beyond a basic bells-only system, partly on cost but also because installers will spot different vulnerabilities in your property, from a poorly secured side gate to an old stopcock cupboard that doubles as an easy entry point.
How We Select & Rate The Best Alarm & Security Installers in Worthing
Ranking is driven primarily by review rating and review count from public business listings, with a small lift given to businesses that show a working website and phone number. We check each business's homepage to confirm alarm and security installation work is what they primarily offer, and listings flagged as permanently closed are removed automatically. Businesses marked Trust Verified 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 complete list. Other businesses on this page haven't been independently verified by us, and appearing here isn't an endorsement. Always carry out your own checks before hiring anyone.
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 & security installer cost in Worthing?
A basic wired burglar alarm for a three-bedroom semi typically runs from around £350 to £600 fitted, while a wireless smart system with app control and a couple of external cameras can land between £600 and £1,200. Full CCTV setups with multiple cameras and recording equipment often start around £800 and climb past £2,000 depending on coverage and camera quality. Monitoring contracts, if you want a 24-hour response service, add anywhere from £15 to £35 a month on top. Prices vary with property size, whether you're rewiring or retrofitting, and how many entry points need covering, so getting two or three quotes before deciding is normal and sensible.
Do I need planning permission to fit CCTV cameras in Worthing?
For most homes, no. Domestic CCTV generally falls outside planning permission as long as cameras only capture your own property and don't point directly into a neighbour's garden or windows. If you're in a listed building or conservation area, which covers parts of Worthing's older housing stock near the seafront, check with the council before drilling into brickwork or render, as there may be restrictions on external fixtures. A decent installer should flag this during the initial survey rather than leaving you to find out afterwards.
What's the difference between a monitored and unmonitored alarm system?
An unmonitored system sounds a siren and, with smart systems, sends an alert to your phone, but it relies on you or a neighbour to respond. A monitored system is connected to an alarm receiving centre that gets notified automatically and can contact you, a keyholder, or the police depending on the response level you've paid for. Monitored systems cost more upfront and come with a monthly fee, but they suit anyone who travels for work, has a holiday let near the seafront, or simply wants a faster response than a phone notification while they're asleep.
How long does it take to install a house alarm or CCTV system?
A straightforward wireless alarm for an average semi usually takes half a day to a full day, including setting up sensors and testing the system. Wired systems take longer because of the cabling involved, sometimes two days for a larger property, especially if cables need running through lofts or under floors. Adding CCTV cameras alongside an alarm can extend the job by another few hours per camera, more if recording equipment needs installing separately and connecting to your home network.
Will a house alarm affect my home insurance in Worthing?
Many insurers offer a discount, sometimes 5% to 15%, for homes with an approved alarm system, particularly one installed by an NSI or SSAIB-accredited installer. It's worth checking with your insurer before installation which standards they recognise, since some policies specify a minimum grade of alarm or require monitoring for the discount to apply. Keep the installation certificate and any accreditation paperwork, as insurers will usually ask to see it if you ever need to make a claim.
How do I choose between alarm and security installers in Worthing?
Start by checking recent reviews on public listings sites and look for consistency, not just a high average, since a handful of five-star reviews from years back tells you less than a steady flow of recent feedback. Ask each installer for proof of qualifications and accreditation body membership, and check they carry public liability insurance, ideally seeing the certificate rather than just taking their word for it. Confirm how long they've been trading and ask for a couple of local references if you can. Get a written quote covering exactly what's included, warranty length and ongoing monitoring costs before you sign anything, and don't be afraid to ask what happens if kit fails within the first year.
