CCTV installation is one of the fastest-growing areas of work for UK electricians. Homeowners and businesses are investing heavily in security, and the electrical and cabling work required for a professional CCTV installation falls squarely within an electrician's skill set.
This guide focuses on the electrical and cabling costs of CCTV installation — the work that an electrician quotes and carries out. This includes running cables to camera positions, providing power to the recording equipment, installing UPS backup, and ensuring the installation complies with BS 7671.
Modern IP camera systems have simplified CCTV installation significantly. With PoE (Power over Ethernet), a single Cat6 cable carries both data and power to each camera, reducing cabling work by half compared with traditional analogue systems.

The choice between PoE and traditional power significantly affects the cabling cost and complexity of a CCTV installation.
For new installations, PoE is almost always the better choice. The only situations where traditional power might be preferred are very long cable runs (over 100 metres, though PoE extenders can address this) or integration with existing analogue systems.
Cabling is typically the largest part of the electrical installation cost for CCTV. The type and length of cable runs, building construction, and access all affect the price.
The recording device (DVR for analogue systems, NVR for IP camera systems) needs a reliable power supply. A UPS is strongly recommended to keep the system recording during power interruptions.
Locate the NVR and PoE switch in a secure, ventilated location — ideally a locked cupboard or utility room. If a burglar can easily access and remove the NVR, the CCTV footage is lost. Cloud backup to a remote server provides an additional layer of protection.
The choice between IP and analogue cameras affects the cabling requirements, image quality, and total installation cost.
For new installations, IP cameras with PoE are the clear choice. The single-cable installation is faster and cheaper to install, the image quality is superior, and the smart features (push notifications, person detection, cloud backup) provide a much better user experience. Analogue systems still have a role when upgrading existing installations with coaxial cable already in place.
A domestic CCTV installation typically involves 2 to 4 cameras covering the front and rear of the property, with an NVR located inside the house.

Commercial CCTV installations are larger, more complex, and higher value. They often involve longer cable runs, outdoor containment, multiple recording devices, and integration with access control and alarm systems.
Elec-Mate's quoting app lets you itemise every camera, cable run, and power component with real trade pricing.

For electricians, combining CCTV and external lighting in a single quote provides a more complete security solution and increases the job value. Always consider lighting when surveying for a CCTV installation.
Any CCTV system that captures images of identifiable individuals is processing personal data under the UK General Data Protection Regulation (UK GDPR) and the Data Protection Act 2018. Both domestic and commercial installations have obligations.
As the electrician, you are not responsible for your customer's GDPR compliance, but advising them of these obligations demonstrates professionalism and helps avoid problems down the line. Include GDPR signage in your quote as standard.
CCTV installation is an excellent diversification for electricians. The skills are transferable, the margins are good, and demand is consistently strong. Here are tips for quoting CCTV work effectively:
Do not just quote the cabling work — supply the complete system including cameras, NVR, UPS, and cabling. Source equipment at trade prices (Hikvision, Dahua, and Uniview offer excellent trade pricing) and mark up appropriately. A complete supply-and-install package is more convenient for the customer and more profitable for you.
Always survey the site before quoting. Walk the perimeter, identify the camera positions, plan the cable routes, and assess the lighting conditions. Use a smartphone to take photos from the proposed camera positions at the correct height — show the customer what each camera will see. This builds confidence and justifies your pricing.
CCTV systems benefit from annual maintenance — cleaning lenses, checking cable connections, updating firmware, and verifying recording. Offer an annual maintenance contract at £100 to £200 per year for domestic systems and £200 to £500 for commercial. This provides recurring revenue and keeps you as the customer's trusted security installer.

Elec-Mate is my go to app for business and electrical work. It's feature rich without feeling cluttered. A true all in one app for quotes, certs, calculations, RAMS, EICRs, and more. I use it every day without fail, and it makes my workflow much smoother since I'm not jumping between apps anymore. The price-to-feature ratio is excellent. Any issues I've had, the developer responds within the hour and usually fixes them the same day. 100% recommend.
I've used the app and the web based version for a while now and it's well worth the investment. If you're an apprentice or experienced Spark give it a go, you won't be disappointed.
I've been using Elec-Mate for a while now, and honestly, it's one of the best apps I've ever downloaded. Every aspect of it feels thoughtfully designed, from the clean and intuitive interface to the powerful features that make everything so easy to manage. It's clear that a lot of care and attention went into building this app, and it shows in every detail.
