Is fire detection a legal obligation for your business premises?

01Who actually prescribes fire detection?

The framework is set by the Fire Protection Act, and the specific requirements for your building are determined by secondary regulations and the fire threat assessment. Put simply: buildings are classified into threat categories, and from the category and use follow the measures, from fire extinguishers to a full fire detection system with alerting.

Alongside the law, fire detection is often required by two more documents: the occupancy permit (for new builds and repurposing, the fire protection project can prescribe fire detection as a condition) and the insurance policy, because insurers for warehouses and production often make it a condition or significantly lower the premium with installed fire detection that alerts a centre.

02In practice: for whom fire detection is typically mandatory

Without going into every regulation, from practice: an obligation or a very strong recommendation, as a rule, exists for the following premises.

• Warehouses and logistics spaces, especially with flammable materials or high-value goods
• Production halls and workshops with processes that heat, weld or use flammable substances
• Hospitality venues and hotels (accommodation capacities almost without exception)
• Shopping centres and larger retail spaces
• Office buildings above a certain size and height, and common areas of residential-business buildings with garages
• Spaces with many people: halls, schools, kindergartens, care homes, clinics

For a small 40 m² office, fire detection is most often not a legal obligation. Whether it's a smart investment is another question: a server cabinet that overheats on Friday night does damage by Monday that a €60 detector would have reported in the first minute.

03Installation is half the obligation. The other half is testing

A common misconception: we've installed fire detection, we're done. Not so. Regulations require maintenance and periodic testing of the system within prescribed intervals, with documentation you keep and show to the inspector. In practice that means a contract with an authorised contractor who services and tests the system and issues records of it.

That's exactly where most buildings fail the inspection: the system exists, but the last test was three years ago, half the detectors are dusty, and there are no records. Our model: we keep track of the deadlines, schedule ourselves, and the documentation folder sits with you, ready for every inspection.

04How much does it cost?

• Smaller business premises up to 200 m²: a complete system with design and installation roughly €1,500 to €3,000
• Medium buildings (500 to 2,000 m²): by project, most often €4,000 to €12,000 depending on the number of detectors and zones
• Annual maintenance with periodic testing: from a few hundred euros for smaller systems, with a fixed price in the contract
• Connection to the 0-24 alarm receiving centre: a monthly fee, often cheaper bundled with intrusion protection

For context: the average damage and downtime after a serious fire in business premises is measured in tens of thousands of euros, and some insurers refuse or reduce payouts if the prescribed protection measures weren't in place. Fire detection is one of the rare items where cost and risk can be compared on a calculator.

05How to check what applies to you: 3 steps

• 1. Get out the documentation: the fire threat assessment (if it exists), the fire protection project from the occupancy permit and the insurance policy. Those three documents most often say it all.
• 2. If documentation is missing or unclear, order a review: on a free site visit we inspect the space and documents and say what's an obligation, what's a recommendation and what's unnecessary.
• 3. Set the deadlines: if an obligation exists, arrange installation and a testing contract before the inspector sets the deadline, with a fine attached.
