Intruder Alarms in Bishop's Stortford
Solid-walled period stock where wireless avoids destructive cable runs.

Intruder Alarms in Bishop's Stortford: what we come across
The older housing around the town centre and Hockerill is mostly solid-wall construction with awkward or non-existent cable voids. That single fact decides most alarm jobs in Bishop's Stortford: a wireless system goes in within a day without lifting carpets or chasing walls, where a wired system would mean real disruption to an occupied house.
Ajax is what we fit most often here: the app control is good, battery life runs to years rather than months, and the panel supervises every device so you are told if one stops responding rather than discovering a gap later.
On the newer estates either option works. If a property is mid-refurbishment with walls already open, wired becomes the sensible choice and we will say so.
Typical jobs here
- Wireless retrofits into occupied period properties
- Ajax systems with app control and pet-tolerant detection
- Wired installs during extensions and refurbishments
- Servicing and takeover of alarms installed by others
- Commercial systems for town-centre units

Questions
Intruder Alarms in Bishop's Stortford: common questions
More general questions are answered on our Intruder Alarms page.
- Our house has solid walls and no loft access. Can you still fit an alarm?
- Yes. This is exactly where wireless earns its keep. No chasing, no lifted floors, and most installs are done within a day.
- Will it work with our dog?
- Yes. Pet-tolerant detectors ignore animals below a set size, and we position them around your actual pets rather than to a template. An alarm that false-triggers is an alarm that gets switched off.
- Can you take over servicing an alarm someone else fitted?
- Usually. We will inspect it, tell you honestly what condition it is in, and either service it or explain why replacing works out better value.

Testimonials
Trusted across Hertfordshire
“I couldn't be happier with the service I received. From start to finish, everything was handled professionally and with great attention to detail. The AJAX alarm system was installed to a very high standard, and everything was explained clearly so I felt confident using it straight away. Mitch was punctual, friendly, knowledgeable, and took real pride in their work. They left everything clean and tidy, and it was obvious they genuinely cared about doing an excellent job rather than rushing through it. If you're looking for someone reliable who provides outstanding workmanship and first-class customer service, I wouldn't hesitate to recommend them.”
