By the DC Fire & Security engineering team — installing and maintaining fire and security systems since 2010. Updated June 2026.
For businesses: usually yes — £150–£500/year for small systems (more for estates) buys an annual preventive service, priority callouts, and the documented working-order status insurers expect, against silent failures (dead drives, drifted cameras) that otherwise surface only after incidents. For homeowners with simple systems: pay-as-you-go servicing every year or two is often sufficient. The contract's value is response and records.
Business case: a single emergency callout plus a replacement drive bills £200–£400 — one incident funds the contract year, before counting the failure you didn't have because the service caught the dying drive in March. Add the insurance angle (CCTV-as-policy-condition premises must evidence maintenance) and the GDPR accountability angle, and contracts are simply how commercial CCTV is run properly. Home case: simpler systems, lower stakes — an ad-hoc service visit (£100–£180) every 12–24 months keeps a domestic system honest without a standing contract, unless monitoring or insurer conditions apply.
Compare like-for-like: visits per year and the actual checklist; response time in hours (not 'priority'); what's included (labour? parts? drives — the most-replaced item?); remote monitoring or visit-only; exclusions (vandalism, lightning, third-party network changes — standard, but know them); term and exit (annual rolling beats long lock-ins); and whether reports are issued per visit. Watch the 'free maintenance' bundled in lease deals — priced in, rarely specified. Ours run annual-rolling with per-visit reports and the option of folding CCTV into a combined fire-and-security compliance package — one schedule, one invoice, every system covered (see compliance packages).
If the guide has helped you narrow the specification, these are the relevant installation, maintenance and local service pages for the next stage.
