What is fire protection engineers insurance?
Fire protection engineers insurance is cover for firms that install, maintain and inspect fire extinguishers, sprinklers, suppression systems and passive fire protection. It combines public and products liability, including claims that equipment failed in a fire, with employers' liability, professional indemnity for design or inspection, and cover for tools and stock.
Fire protection is judged on a day nobody plans for. If an extinguisher your engineer passed will not discharge, a sprinkler valve was left shut after maintenance or fire stopping around a pipe was missing, the building owner and their insurer may claim that your work made the fire worse. The opposite risk is just as real: a sprinkler head knocked during a service can flood a warehouse.
Fire alarms and detection are covered on our alarm installers insurance page. This page covers the equipment and systems that fight or contain a fire.

What does fire protection engineers insurance cover?
Fire protection firms usually combine the sections below. The balance depends on whether you service portable equipment, install fixed systems or carry out passive work.
Failure in a fire
Claims that extinguishers, sprinklers or fire stopping you installed or maintained did not perform, and that the fire spread further as a result.
Read more about products liability insurance
Accidental discharge
Damage when a sprinkler head is knocked, a suppression system is set off during maintenance or an extinguisher is discharged in a server room.
Read more about public liability insurance
Fire extinguisher servicing
Commissioning, annual servicing, extended servicing and refilling of portable extinguishers, the core work of extinguisher service engineers.
Sprinkler systems
Installing and maintaining wet and dry sprinkler systems, pumps and tanks, where leaks, freezing pipes and closed valves cause the claims.
Suppression systems
Kitchen, server room and special hazard suppression. Gas-based systems also bring a risk to anyone in the room when they discharge.
Passive fire protection
Fire stopping, fire doors, intumescent coatings and compartment surveys, where missing or poorly recorded work is often found only after a fire.
Read more about contractors' all risks cover
Design and inspection
System design, hydraulic calculations, fire risk assessments and inspection reports that a client relies on.
Read more about professional indemnity insurance
Engineers and fitters
Employers' liability for injuries from pressurised cylinders, falls from ladders and lifts, and manual handling of extinguishers and pipe.

Tools, stock and refill workshop
Extinguisher stock, spare parts, test equipment and refill equipment in vans and at your workshop.

How much does fire protection engineers insurance cost?
Fire protection firms are rated on what they do and how they prove it. These are the factors insurers weigh most.
Activity mix
Extinguisher servicing, sprinklers, suppression, passive work and risk assessment carry very different risks, so the turnover split comes first.
Certification
Third-party certification of your firm and the training records of engineers carry real weight with underwriters.
Design and inspection
Firms that design systems, sign off compartments or write risk assessments need professional indemnity, priced on fees and work type.
Building types
High-rise residential, healthcare, data centres and warehouses with high stock values attract closer questions.
Records and evidence
Photographic records of fire stopping, service logs and asset tags help defend claims and reassure insurers.
Claims and wage roll
Accidental discharge and failure claims count heavily, while engineers' pay sets employers' liability.
What fire protection engineers insurance usually excludes
Claims against fire protection firms tend to fail or shrink on these points.
- Fire alarm and detection work that was not declared, a risk set out on our alarm and CCTV installers page
- Advice, design or inspection errors causing financial loss, unless professional indemnity is held
- Redoing fire stopping or sprinkler pipework you installed defectively, although resulting damage may be covered
- Work on high-rise residential buildings or special hazard sites that was not declared
- Gradual leaks from sprinkler pipework that went unreported
- Pollution from foam or suppression agents, unless covered by an environmental policy or sudden and accidental cover
- Service vans while driven, which need their own commercial vehicle insurance
Active or passive fire protection: how the cover differs
Active systems fight a fire; passive measures contain it. Insurers see different risks in each, and many firms work in both.
| Feature | Active fire protection | Passive fire protection |
|---|---|---|
| Typical work | Extinguishers, sprinklers, suppression, risers | Fire stopping, fire doors, coatings, boards |
| Claim between fires | Accidental discharge and sprinkler leaks | Rarely, as nothing moves |
| Claim after a fire | Equipment did not operate | Fire or smoke passed through a gap |
| Evidence that matters | Service logs and asset tags | Photographs of every penetration and door |
| Design cover | Hydraulic and system design | Compartment surveys and product selection |

How much does fire protection engineers insurance cost?
It depends on your activity mix, certification, design and inspection work, the buildings you work in, your records, wage roll and claims. A sprinkler contractor on warehouses is rated differently from an extinguisher servicing firm working in offices.
Are fire extinguisher service engineers covered?
Yes. Supplying, commissioning, servicing and refilling portable extinguishers is a standard activity. Insurers ask about service volumes, engineer training, refill workshop arrangements and whether your firm holds third-party certification.
Are we covered if an extinguisher we serviced fails in a fire?
Usually under products or public liability, if the failure was caused by your negligence and led to injury or extra damage. Insurers look for service records showing what was checked, so good records are central to defending a claim.
Is accidental discharge of a sprinkler or suppression system covered?
Damage caused by your engineers setting off a system or damaging a sprinkler head is normally a liability claim. Expect a separate, often larger, excess for water damage on many policies.
Do passive fire protection contractors need different cover?
The core covers are the same, but insurers ask more about record keeping, product certification and design responsibility. Fire stopping problems may only surface after a fire or a building safety review, sometimes years later.
Do fire protection engineers need professional indemnity?
Usually, yes, if you design sprinkler or suppression systems, write fire risk assessments or certify compartments. A client who relies on your advice and suffers financial loss would need professional indemnity, not liability cover, to respond.
Are high-rise residential buildings covered?
Often, but they must be declared. Insurers have become more cautious about fire safety work on taller residential buildings, and some limit or exclude it. Give the broker a clear picture of these projects.
Does the policy cover our refill and recharge workshop?
It can. The premises, refill equipment, stock and staff working there can be insured on the same policy, with employers' liability covering injuries from pressurised cylinders.
How do I get a fire protection engineers insurance quote?
An enquiry from this page goes to a broker who places fire safety firms. Expect questions on your activity split, certification, records, building types, contract terms, wage roll and claims.
