The cost of CCTV installation in London varies significantly depending on the number of cameras, camera resolution, cable runs and recording equipment. Understanding the main cost drivers helps you get an accurate quote and avoid overpaying for features you do not need. Our NSI Gold approved engineers have installed CCTV systems across London since 2010 and this guide reflects current market pricing for professionally installed systems.
This article covers typical price ranges for domestic and commercial systems, the factors that push costs up or down, and what to include and exclude when comparing quotes. For a free, fixed-price quote specific to your property, call 0800 000 0000 or request a free survey.
Domestic CCTV Installation Costs in London
A professionally installed domestic CCTV system in London typically costs between £500 and £1,500 for a four-camera installation, supply and fit. This price range covers the camera units, NVR recorder, hard drive storage, cabling, brackets, conduit and the installation labour. A wider range exists because cable runs in London's Victorian terraced properties can be considerably longer and more complex than in modern new-build homes.
Four-Camera Domestic System
A four-camera system covering front door, rear garden, side gate and driveway is the most common domestic installation in London. With 1080p cameras and 1TB NVR storage (approximately 28 days retention), expect to pay between £600 and £900 supply and fit. Upgrading to 4MP cameras adds approximately £100 to £150 to the total. Colour night-vision cameras add a further £50 to £100 per camera compared with standard infrared models.
Eight-Camera Domestic System
Larger detached properties with multiple outbuildings, garages or extended driveways often require eight cameras for complete perimeter coverage. An eight-camera 1080p system with 2TB storage typically costs between £1,000 and £1,600 supply and fit in London. Prices rise further on properties where cables must be routed through multiple floors or thick stone walls.
Commercial CCTV Installation Costs in London
Commercial CCTV pricing varies widely based on site complexity. A small London office with eight cameras covering reception, a server room, two exits and a car park space can be installed for between £1,500 and £2,500. A large warehouse or multi-storey retail unit with 16 to 32 cameras, PTZ units and ANPR at vehicle access points may cost £5,000 to £15,000 or more.
Factors That Affect Commercial Pricing
The main cost drivers for commercial installations are the number of cameras, camera resolution and type (fixed versus PTZ), cable run distances, working at height (scissor lift or cherry picker hire), out-of-hours installation, and integration with access control or alarm systems. NVR storage capacity and the number of hard drives required also affect the total cost. We provide itemised quotations so you can see exactly what you are paying for.
What Affects the Final Price?
Cable runs are often the largest variable. A camera mounted directly above the NVR requires only a short cable, while a camera on the far side of a large warehouse may need 50 to 80 metres of cable plus a separate power supply if PoE is not viable. Our engineers calculate cable quantities during the site survey and include all materials in the fixed-price quotation.
Working at height adds cost when cameras need to be mounted above three metres on scaffolding, extendable ladders or cherry pickers. Our engineers specify and quote for the access equipment required at each camera position. There are no surprises in the final invoice. Request a free survey and fixed-price quote.
Frequently Asked Questions
Are Cheaper Online CCTV Kits Worth Buying?
Retail CCTV kits sold online typically cost £150 to £400 for four cameras and an NVR. The cameras in these kits are often lower resolution than their specifications suggest, use poor quality IR LEDs with limited range, and come with NVRs that fail within one to three years. Professional systems use commercial-grade equipment with longer lifespans and are installed correctly the first time, avoiding the cost of revisiting poorly positioned cameras.
Does NSI Gold Approval Increase the Cost?
NSI Gold approved contractors operate to higher standards than non-approved installers, which can add a modest premium to installation costs. But the additional cost reflects genuine quality: better survey and specification, correct camera positioning, clean professional installation and full documentation. Many insurers discount premiums for properties with NSI-approved CCTV installations, partially offsetting the cost difference.
Is VAT Included in CCTV Installation Quotes?
All our quotations are provided exclusive of VAT. VAT at 20 per cent is added on the final invoice. Domestic CCTV installation is subject to standard-rate VAT and there is currently no reduced rate applicable. We confirm all pricing including VAT in our written proposals so there is no ambiguity before you make a decision.
