Fire Alarm Systems in Hertford
Listed buildings in commercial use: the hardest fire brief we take on.

Fire Alarm Systems in Hertford: what we come across
A listed building in commercial use is the most demanding fire job we do. The premises carries the same statutory duties as any other, but the options for achieving it are constrained by what can be fixed, chased or routed through the fabric. Hertford’s town centre has a lot of exactly this: period buildings operating as shops, offices, salons and restaurants.
In practice it means careful device siting, wireless or radio-linked detection where cable runs would be destructive, and emergency lighting chosen to sit acceptably in a period interior.
Restaurants and cafés add the kitchen question, which is always heat detection rather than smoke. Get that wrong and the system gets disabled within a week.
Typical jobs here
- Detection in listed buildings under commercial use
- Radio-linked systems where cabling would be destructive
- Heat detection specified for commercial kitchens
- Emergency lighting sympathetic to period interiors
- Servicing and logbook maintenance for town-centre premises

Questions
Fire Alarm Systems in Hertford: common questions
More general questions are answered on our Fire Alarm Systems page.
- How do you fit fire detection in a listed commercial building?
- Wherever cable runs would damage historic fabric we use radio-linked detection, and we site devices to minimise visual impact. The statutory duty does not change because a building is listed: only the way we meet it does.
- Our kitchen sets the alarm off constantly. Can that be fixed?
- Almost always. It usually means a smoke detector is fitted where a heat detector belongs. Swapping the detection type for the environment fixes it.
- Can you keep our servicing records in order?
- Yes. We carry out the periodic servicing and keep the logbook up to date, which is what you will be asked for if anyone inspects.

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.”
