Harlow's housing stock runs in two clear bands and they need different specifications. The original new town neighbourhoods are post-war terraces, maisonettes and low-rise blocks, often with shared entries, rear gardens backing onto green space and side returns that are easy to reach unseen. Church Langley on the eastern edge is nineties and later, mostly detached and semi-detached with integral garages and side gates, and the risk there is opportunistic entry through a garage or utility door rather than the front. On the commercial side, units on Templefields and The Pinnacles are frequently multi-tenanted with a shared yard and one gate, which means the alarm has to be zoned so one tenant working late does not lock everyone else out of their own premises. External fittings have to respect local rules, and we always work to the guidance published by Harlow Council.
The two things that go wrong with alarms in Harlow are false activations and systems nobody uses. On terraced and maisonette streets, detectors placed without thought for shared party walls and communal entries generate call-outs until the occupier stops setting it. We zone around how the building is actually lived in. For letting agents managing void and changeover properties across the town, we set up Ajax with user codes per tenancy so you are not rekeying a system every time somebody moves out, and you can see activity without a site visit. On schools and commercial sites we specify grading to match what your insurer actually requires rather than fitting the most expensive panel in the van and calling it best practice.
Harlow is growing fast on its edges, and the newest homes sit a long way from the original new town layout, with parking courts, shared footpaths and open green edges. Plenty of new homes are handed over with no alarm, or a bell box with nothing behind it. We fit Ajax wireless, so nothing gets chased into new plaster and it all runs from your phone.
Fire and security is all we do — from design to long-term maintenance, across every system.
An East Anglia-based team means faster surveys, quicker call-outs and engineers who know the area.
