CCTV Installation
London & South East

CCTV installation cost in London varies based on the number of cameras, camera type, cable routing requirements, and whether you need a wired or wireless system. A basic 4-camera residential system typically starts from around £500–£800 installed. A commercial system covering a small business premises — say 8–12 cameras with a full HD NVR, remote access, and maintenance plan — will typically range from £1,500 to £3,500 depending on the specification.

We always carry out a free site survey before quoting. This is the only reliable way to give you an accurate figure — square footage and number of cameras alone do not determine cost, because cable routing, access, and the specific cameras required for your coverage goals all affect the price. All quotes are itemised, with full product specification included.

Yes, CCTV installation is legal on your property in London, provided it complies with the UK GDPR and the Information Commissioner's Office (ICO) guidance on surveillance cameras. For residential properties, cameras must not record your neighbours' gardens, driveways, or the public street without good reason — if they do, that footage falls within GDPR scope.

For businesses, you must display clear CCTV signage informing people they are being recorded, have a documented reason for operating CCTV, and handle footage securely with defined retention periods. Our engineers advise on camera placement to ensure maximum coverage while remaining ICO compliant. You can read more about UK business CCTV obligations in our UK Business CCTV Laws guide.

The number of cameras depends on your property's layout, the number of access points, and what you want to cover. A small retail unit in London typically needs 4–6 cameras covering the entrance, shopfloor, stock area, and external frontage. A commercial office building or warehouse will need a proper site survey to determine coverage — an engineer will walk the site and map blind spots before making a recommendation.

In our experience, most commercial clients in London initially underestimate the number of cameras they need — particularly for external perimeter coverage where one camera rarely has the field of view to cover an entire face of a building. The site survey exists precisely to address this before installation, not after.

Yes. All IP and modern HD CCTV systems installed by Triple Star include remote access as standard. You can view live camera feeds and access recorded footage from a secure mobile app on iOS or Android, or via a desktop portal — from anywhere in the world with an internet connection.

For IDIS systems, this is managed through the IDIS Mobile app, which also supports motion alert notifications — so if a camera detects movement outside business hours, you receive a notification and can pull up the footage immediately. Remote access is configured as part of our standard installation process.

HD analogue cameras use coaxial cable and are available in resolutions up to 8 megapixels. They are compatible with existing coaxial infrastructure if you are upgrading an older system, and tend to be lower cost than IP equivalents. For many small commercial premises, an HD analogue system with a DVR is a practical and cost-effective solution.

IP cameras connect over a data network using Cat5e or Cat6 cable and offer higher image quality, more advanced analytics, and greater flexibility for expanding the system. They record to a Network Video Recorder (NVR) and are the better choice for larger commercial sites, sites requiring AI-based analytics, or where you want to integrate CCTV with access control or intruder alarms. For new installations in London commercial properties, we typically recommend IP systems unless budget or existing infrastructure makes analogue HD a better fit.

Yes. Triple Star offers annual CCTV maintenance plans covering engineer site visits, camera recalibration and cleaning, DVR/NVR health checks, hard drive diagnostics, remote access verification, and priority call-out in the event of a system fault. Maintenance is the part of CCTV ownership most often overlooked — cameras shift position, lenses collect grime, and hard drives degrade, all of which compromise the quality of your footage precisely when you most need it.

We maintain the systems we install across London and the South East. If you have an existing system from another installer and are looking for an SSAIB certified maintenance contractor, contact us — we can take on third-party system maintenance subject to an initial site assessment.
