How to Price CCTV Installation: Camera Types, Cable Runs and NVR Systems

Quick Answer: A standard 4-camera domestic CCTV system installed costs £900–£1,800 in 2026, an 8-camera system £1,500–£2,800, and a 16-camera commercial install £3,500–£8,500 depending on resolution, recording capacity, and cable routing complexity. PoE-cabled IP systems with 2K (4MP) cameras dominate the new-install market, while wireless battery-camera systems sit in the £400–£900 range supply-only with limited ongoing reliability. CCTV installations must comply with the UK GDPR and Data Protection Act 2018 if any audio is recorded or any of the camera coverage extends beyond the property boundary.

Summary

CCTV is one of the most over-quoted and under-quoted trades simultaneously. Over-quoted because there's no qualifications or licensing barrier — any electrician with a screwdriver can call themselves a CCTV installer, and prices vary 3–4× for nominally identical specs. Under-quoted because the install labour scales with cable routing, not with camera count — a 4-camera system on an open new-build runs in 4–6 hours; the same 4 cameras retrofitted into a 1930s solid-walled house with three lofts and a basement is 2–3 days.

The market has consolidated around three system architectures: wired IP / PoE NVR (Network Video Recorder; 80% of new domestic installs); wired analogue HD-CVI/HD-TVI / DVR (legacy commercial, slowly being phased out); and wireless battery-camera with cloud subscription (DIY-friendly, retail-focused, 15% of domestic). Each has very different price structures and very different long-term costs.

Pricing must address: camera count, resolution (2MP, 4MP, 8MP / 4K, 12MP), recording capacity (NVR storage), cable routing complexity, mains power for the NVR, monitoring (live view, motion alerts, professional monitoring), and any compliance overhead (GDPR-required signage, data subject access procedures for footage requests). A clean quote separates supply, install labour, cable, NVR/storage, and ongoing costs (cloud subscription, monitoring fees) so the client can see the lifetime cost picture.

Detailed Guidance

System Architecture Choice

Wired PoE IP / NVR is the default new-install architecture in 2026. Cameras connect by Cat 6 cable to a PoE switch (or directly to a PoE NVR), which carries both power and data on the same cable. The NVR records to internal hard drives (typically 2–8 TB), provides web and app access, and integrates with mobile alerts. Lifecycle cost is low after install — no subscription required. The downside is install labour: every camera needs a cable run from its position back to the NVR location.

Wireless battery cameras with cloud storage (Ring, Eufy, Nest, Reolink Argus) trade install simplicity for ongoing cost. Battery life is 2–6 months per charge; cloud storage requires a subscription (£30–£90 per year per camera). Suitable for retrofits where running cable is impractical. Less reliable in cold weather (battery life drops 30–50% below 5°C) and over wide-area coverage.

Wired IP with cloud-only recording (some commercial systems, increasingly common) replaces the NVR with cloud storage. Lower upfront hardware cost, higher ongoing subscription. Vulnerable to internet outage unless a local edge recorder is added.

Analogue HD coax with DVR is legacy. Still installed for budget commercial replacement work where existing coax cabling is being reused, but new cabling is rarely coax — IP/PoE has won.

Resolution Selection

Resolution affects file size, NVR storage, and cost. The practical points:

Cable Routing: Where Quotes Go Wrong

The labour to run cables varies enormously with site condition. Pricing rules of thumb for a single Cat 6 run from camera to NVR location:

A 4-camera system might be £400 in cable labour on a new-build extension and £900 on a Victorian terrace. Quoting from drawings without site survey is the most common cause of underrun on CCTV jobs.

NVR Sizing and Storage

Storage requirement depends on resolution, frame rate, compression and recording mode. Practical numbers:

For an 8-camera 2K continuous-recording system at 30 days: 8 × 540 GB = 4.32 TB total. A 6 TB NVR drive costs £140–£220 over a 4 TB. Always over-spec storage by 20–30% — drives don't perform well at >85% full.

NVR Location

NVR location matters. It needs:

Common locations: under-stairs cupboard, utility room, loft (with cooling consideration), dedicated equipment room (commercial). Avoid unconditioned outdoor cabinets — hard drives don't like temperature swings.

Compliance: GDPR and CCTV

UK GDPR and the Data Protection Act 2018 apply to any CCTV that captures images of identifiable people beyond the property boundary. Domestic CCTV pointed only at your own property is exempt under the household exemption — but the moment a camera shows the public pavement, neighbours' gardens, or a shared driveway, GDPR applies.

Compliance requirements:

Quote stage: ask the client where the camera coverage extends. Recommend boundary signage and a written CCTV policy for any commercial install. Free template policies are available from the ICO website.

Operator and Monitoring

DIY monitoring — the standard model. Live view via smartphone app, motion alerts pushed to phone. No ongoing cost beyond replacement hardware.

Professional monitoring — the camera signal is monitored by an Alarm Receiving Centre (ARC). Suspicious activity triggers operator review and police response if criteria are met. £180–£480 per year. Common for commercial; rare for domestic.

Smart-home integration — Alexa, HomeKit, Google Home. Doorbell-camera integration is the volume case. Adds £80–£280 to commissioning labour for full integration.

Programme on a Typical 4-Camera Domestic Install

Add 0.5–1 day for complex retrofits; 0.5 day for 4K instead of 2K (configuration tweaks, more storage to set up, but install time is the same).

Frequently Asked Questions

Do I need an electrician to install CCTV?

Not formally — CCTV is "extra-low voltage" (ELV) wiring and falls outside the BS 7671 scope for the camera circuits themselves. But the NVR mains supply (240 V fused spur) is notifiable electrical work in some scenarios — Part P applies to a new circuit. If you're a CCTV installer without electrical qualifications, sub-contract the mains side to a Part P-registered electrician or notify building control directly.

What's the difference between 2MP, 4MP and 4K — does it matter for a domestic install?

For wide-area garden coverage, yes — 4MP gives much better digital zoom and identification range than 2MP. For close-range doorbell or door-coverage cameras, 2MP is fine. A typical balanced spec is 4MP for outdoor area cameras and 2MP for fixed close-range positions, but 4MP across the board is now common given the small price gap.

Can I record audio?

Yes, but with careful compliance. Audio recording falls under stricter GDPR rules than video. For commercial installs, audio is generally disabled by default. For domestic where the camera covers the property only, audio is permissible. Where coverage extends beyond the boundary, audio should be off and signage should make this clear.

What about cellular / 4G CCTV systems?

Useful for sites without internet or for portable / temporary coverage (construction sites, holiday homes). Hardware cost is similar to wireless battery; ongoing cellular data subscription £15–£40 per camera per month. Niche use case but a real one — quote separately.

Why does the same 8-camera system vary 2× in price between contractors?

Three main reasons. First, cable routing — a slow, careful install with concealed cabling is double the labour of a fast, surface-mounted install. Second, hardware spec — 4MP vs 4K, 4 TB vs 8 TB NVR, premium vs budget brands. Third, profit margin — CCTV is unregulated and price-disciplined less by qualifications than by competition. Cheap installs are usually surface-mounted lower-spec cameras with budget NVRs; premium installs are concealed cabling with brand cameras. Both can be technically valid; the client should know which they're getting.
