How much does a security system cost in the UK?
Security system installation in the UK is a well-regulated trade — reputable installers are accredited by the National Security Inspectorate (NSI) or SSAIB. Here are typical costs for 2025–2026.
Typical security installation costs (2025–2026)
| Job type | Typical price range |
|---|---|
| Alarm system (basic wireless, residential) | £300 – £600 incl. installation |
| Alarm system (multi-zone, monitored, full home) | £600 – £1,200 incl. installation |
| Monitored alarm — ongoing monitoring fee | £15 – £30 per month |
| Alarm servicing / fault repair | £60 – £150 |
| CCTV system (4 cameras + NVR) | £500 – £1,200 incl. installation |
| CCTV system (8 cameras, IP, higher resolution) | £1,200 – £2,500 incl. installation |
| Smart video doorbell installation | £100 – £250 incl. unit |
| Wired intercom (flat/block, 2 stations) | £250 – £500 incl. installation |
| Access control (keypad or fob entry, per point) | £300 – £800 |
| Security assessment (home audit) | £60 – £150 |
What affects the price?
- Property size and layout. More zones, more cameras, longer cable runs, and difficult access all increase cost.
- IP vs. analogue CCTV. IP cameras offer higher resolution and remote access but cost more per camera. Analogue is lower cost but resolution is limited.
- Brand quality. Budget cameras and alarm panels carry a higher long-term failure risk. Established brands (Hikvision, Yale, Ring, ADT) offer a good cost-quality balance.
- Monitoring integration. If you want an alarm linked to a monitoring centre and keyholder/police response, confirm the system meets your monitoring provider's required standard.
- Insurance requirements. Some home insurers offer lower premiums, or require, an NSI/SSAIB-approved monitored alarm for higher-value contents cover — check your policy.
NSI/SSAIB accreditation and your rights
The two main UK accreditation bodies for security installers are the National Security Inspectorate (NSI) and SSAIB. Ask to see the installer's accreditation before work begins — an unaccredited installation may not satisfy your insurer's requirements if a break-in occurs. TruePro verifies NSI/SSAIB accreditation and shows a badge on the installer's quotes and profile once confirmed.
Tips for getting a fair price
- Get a written quote that specifies each camera model, cable length, and all materials — not just a single lump-sum figure.
- Ask whether remote viewing via smartphone is included in the setup and whether there is any ongoing cost.
- For monitored alarms, confirm the monthly monitoring fee and who the monitoring/response partner is.
- Avoid paying the full amount upfront. TruePro's payment protection holds your payment securely until you've confirmed the installation is working correctly.
