Gillingham's mix of Victorian terraces around the town centre, 1930s semis out towards Rainham, and newer estates near Twydall or Hempstead means security needs vary a lot from street to street. A tightly packed terrace off Canterbury Street might need a simple wireless alarm and a decent door chain, while a detached property near Darland Banks could call for CCTV covering a longer driveway or outbuildings. Proximity to the Medway towns and good road links via the A2 and M2 also mean local installers are used to working across Chatham, Rainham and Rochester too, so they've usually seen most housing types the Medway area has to offer.
The businesses featured here are pulled from public business listings and ranked by their review rating and review count, with a modest lift given to those showing a working website and phone number. We check each firm's homepage to confirm alarm and security installation is genuinely their main line of work, which keeps general electricians or unrelated tradespeople off this page. Listings flagged as permanently closed are stripped out automatically. Where you see a Trust Verified badge, that business has gone through our fuller verification process covering trade qualifications and accreditations, public liability insurance, trading history, customer review history and registered company information, and you can find the full detail on our How We Verify page. Businesses without that badge haven't been through that process with us, so it's worth doing your own checks before booking.
Before signing anything, ask to see proof of any relevant certification for the alarm systems being fitted, and check whether the company is registered with a recognised security body, since this can affect insurance requirements too. Get a written quote that spells out what's included, monitoring fees if applicable, and how call-outs or false alarms are handled. It's sensible to get two or three quotes for anything beyond a basic wireless kit, particularly for CCTV or monitored systems, as prices and included extras can differ quite a bit between installers covering the same postcode.

How much does an alarm & security installer cost in Gillingham?
A basic wireless burglar alarm typically costs between £250 and £500 fitted, while a wired system for a larger house can run to £600-£900 depending on the number of sensors and zones. CCTV setups vary widely, from around £300 for a couple of cameras and a recorder to £1,500 or more for a multi-camera system covering a larger plot. Monitored alarms usually add a monthly fee on top, often £15 to £30. Prices depend on property size, whether it's a new install or an upgrade to existing wiring, and how many entry points need covering, so getting two or three quotes is normal practice before committing.
Do I need a monitored alarm or is an unmonitored system enough?
It depends on how often the property's left empty and what your insurer expects. An unmonitored alarm with a loud siren deters casual break-ins and suits homes where someone's usually nearby to hear it. A monitored system, where a control room alerts you or the police, suits properties left unattended for long periods, holiday homes, or anyone wanting extra peace of mind. Check your home insurance policy too, as some insurers offer lower premiums for monitored systems or specific accreditation levels.
Will fitting an alarm or CCTV affect my home insurance?
It can, in a good way. Many insurers reduce premiums for homes with an approved alarm system or CCTV, particularly if it meets a recognised standard. Always check with your insurer beforehand about what specification they require, since fitting the wrong grade of system might not qualify for any discount. Keep the installation certificate and any compliance paperwork safe, as insurers sometimes ask for proof after a claim.
How long does it take to fit an alarm system in a typical Gillingham house?
A straightforward wireless alarm in a three-bedroom semi usually takes half a day to a full day, including setting up sensors on doors and windows and testing the system. Wired systems take longer, often one to two days, because cabling has to be run discreetly through walls and lofts. CCTV installation timing depends on the number of cameras and whether cabling needs running outside, but two to four cameras typically takes a day. Older Victorian terraces with solid walls can add time if cabling's needed rather than wireless kit.
Can I get a smart alarm system that I control from my phone?
Yes, most installers now fit smart systems that link to an app, letting you arm or disarm the alarm, view CCTV footage, and get notifications remotely. These typically cost a bit more upfront than a basic system, often an extra £100 to £200, but are useful if you travel for work or want to check on the house during the day. Ask the installer whether the app requires an ongoing subscription, as some smart features are locked behind a monthly fee after the first year.
What should I check before choosing an alarm or security installer in Gillingham?
Ask to see evidence of relevant qualifications and accreditations for the systems they're fitting, and confirm they hold public liability insurance in case of damage during installation. Look through recent customer reviews for mentions of reliability, tidiness of work, and how they handle call-backs if something goes wrong. Request a written quote itemising equipment, labour, and any monitoring costs, and compare at least two or three before deciding. It's also worth asking how long they've been trading locally and whether they can provide references from recent jobs in the Medway area.
