Security system maintenance: one contract, every system, predictable cost
SEG Ltd provides planned maintenance contracts that cover your entire security estate under a single agreement, CCTV, access control, intruder alarms, door entry, and structured cabling. One supplier, one number to call, one quarterly visit covering everything, one annual invoice. For multi-site customers we coordinate visits across the whole portfolio so you're not juggling six different specialists each with their own ticket system.
Each maintenance visit is structured around a documented checklist per system type. Cameras get physically cleaned and image-quality checked, NVRs get health-checked, access control readers get verified along with their door hardware (closers, strikes, magnets), alarms get walked-tested with PIRs and door contacts triggered. Firmware is updated where the manufacturer has released a release worth applying. Users are audited and leavers removed. Everything is documented and you get a written report after each visit.
Contracts are quoted based on system size, complexity, and visit frequency (quarterly is the most common). In-contract sites get priority response for reactive callouts with a published SLA and discounted labour rates. We can also offer extended cover for landlords and multi-site facilities managers, including urgent priority response and remote monitoring of NVR / panel health between visits.

How our maintenance contracts work
1. Baseline survey
If we're new to the site, we start with a one-off baseline visit to document every system, identify any pre-existing defects, and quote a fair contract price based on the actual estate.
2. Scheduled visits
Visits scheduled into the calendar a year ahead so they never get missed. You get a reminder a week before each visit. Most clients are on a quarterly rhythm.
3. Reactive cover
In-contract sites get a published response SLA for reactive callouts, usually within one to two working days for non-urgent, same-day for system-down. Labour at a reduced rate.
Security maintenance FAQs
Yes, that's most of our maintenance work. We cover Axis, Dahua, Hikvision, Bosch, Hanwha, Avigilon, Paxton, Salto, ACT, Texecom, Pyronix, Honeywell, and most major manufacturers. The baseline visit gets us up to speed on whatever's there.
It depends entirely on system size, number of sites, and visit frequency. As a rough indicator, a single-site small commercial property (12 cameras, 6 doors, intruder alarm) on quarterly visits is typically £600 to £900 per year all-in. We provide a written quote after the baseline visit.
Consumables (batteries for alarm panels and bell boxes, fuses, etc.) are typically included. Larger parts (cameras, drives, controllers) are quoted separately as needed, but in-contract customers get parts at trade pricing rather than retail markup.
Yes, we work with landlords and facilities managers running portfolios of 5, 20, 50+ sites. Single contract, single PO, coordinated scheduling, single report bundle. Volume pricing reflects the operational efficiency.
