Fire Extinguisher Servicing & Maintenance
Fire extinguishers are one of the simplest and most effective first-aid fire measures in a building — but only if they’re the right type, in the right place, and maintained properly.
When they’re missing, out of date, poorly sited, or not suitable for the risks on site, they can give a false sense of security and leave your business exposed.
In the UK, duties around fire safety equipment sit primarily under the Regulatory Reform (Fire Safety) Order 2005 (FSO). The Responsible Person must ensure appropriate fire precautions are in place, including suitable fire-fighting equipment where needed, and that it’s kept in efficient working order.
The practical “how” of extinguisher provision and maintenance is set out in the British Standards:
BS 5306-8 (selection and positioning of portable fire extinguishers)
BS 5306-3 (commissioning and maintenance of portable fire extinguishers)
Whether you manage an office, factory, warehouse, industrial unit, construction site, healthcare premises, school, retail space, hotel, or multi-occupied building, the goal is the same: appropriate coverage, clear identification, and reliable equipment.
Getting the right fire extinguisher coverage starts with a risk assessment
Extinguishers aren’t a “one size fits all” purchase.
A suitable fire risk assessment (and, where necessary, an extinguisher assessment) should consider:
The likely fire classes present (ordinary combustibles, flammable liquids, electrical risks, cooking oils, etc.)
Building layout, escape routes and travel distances
Occupancy type and staff competence
High-risk areas such as plant rooms, kitchens, workshops, charging areas, and storage spaces
Any special hazards (lithium-ion batteries, solvents, welding, dust risks)
This process helps ensure you’re not under-provided (risking non-compliance and poor control) or over-provided (unnecessary cost and clutter), and that the extinguisher types match the risks.
Fire Extinguisher Supply and commissioning to current standards
Supplying extinguishers is more than dropping off equipment in boxes.
A compliant installation should include:
Correct selection of extinguisher types and sizes for the risks identified
Correct siting and mounting so extinguishers are visible, accessible, and not obstructing escape routes
Clear identification so people can find equipment quickly
Commissioning is the point where new extinguishers are checked on site and confirmed as fit for service, including correct pressure/condition checks, location, mounting, and record keeping.
This commissioning process is set out in BS 5306-3 and forms part of your compliance trail.
Signage and identification
If there’s a fire, nobody wants to waste time searching. Extinguishers should be clearly identified with appropriate signage and consistent siting.
Good signage supports safe evacuation and helps staff locate the right equipment quickly, particularly in larger premises, warehouses, shared buildings, or public-facing environments.
Signage should be suitable, consistent, and aligned with workplace expectations and the fire risk assessment findings (for example, extinguisher ID signs and location signs where appropriate).
Why regular servicing matters
Extinguishers are safety-critical devices. Even if they’re never used, they can lose pressure, suffer corrosion, be knocked, have pins removed, or become obstructed by storage and day-to-day clutter.
Regular servicing is how you confirm they remain ready for use.
Under BS 5306-3, maintenance includes a structured inspection of each extinguisher, typically covering:
External condition, damage, corrosion, tamper indicators and safety pin/seal
Pressure/weight checks (as relevant to type)
Hose/nozzle condition and security
Legibility of labels and operating instructions
Correct location and visibility
Service records and labelling
This is exactly the sort of evidence that supports your duties under the Fire Safety Order, helps satisfy insurers, and demonstrates to enforcing authorities that the premises is being managed properly.
One-off visits vs ongoing compliance
We can carry out one-off extinguisher inspections, commissioning visits for new installations, or audits where you’ve taken over a new premises or inherited unknown equipment.
However, the most reliable way to maintain compliance is a planned maintenance arrangement. A maintenance contract keeps servicing on schedule, ensures records stay up to date, and prevents the common problem of “it was done once, then forgotten”.
It also gives you a clear point of contact for replacements, upgrades, site changes, or additional equipment as your business grows.
Who we support
We work with a wide range of clients, including:
Offices and shared workspaces
Factories, warehouses and industrial premises
Construction sites and temporary facilities
Healthcare settings, care homes and clinics
Schools, community buildings and places of assembly
Retail, hospitality and mixed-use buildings
No two sites are identical — and that’s why correct selection, siting, and maintenance matters.
Do businesses legally need fire extinguishers?
Under the Regulatory Reform (Fire Safety) Order 2005, the Responsible Person must provide appropriate fire precautions.
In most workplaces that means suitable “first-aid fire-fighting equipment” such as portable extinguishers, based on the findings of your fire risk assessment.
How do we know what types of fire extinguishers we need?
Correct selection should be based on your fire risks and building layout.
BS 5306-8 provides guidance on choosing the right extinguisher types and coverage for common hazards such as ordinary combustibles, flammable liquids, electrical risks and cooking oils.
How often do fire extinguishers need servicing?
BS 5306-3 sets out the maintenance requirements.
In most cases, extinguishers require annual servicing by a competent person, with additional extended servicing and overhaul intervals depending on extinguisher type and manufacturer guidance.
What happens during a fire extinguisher service visit?
The engineer will check each extinguisher’s condition, safety pin and tamper seal, pressure/weight (as applicable), hose/nozzle, labels, and mounting location.
Any defects are recorded, the service label is updated, and you receive documentation to support compliance.
Do we need signage for fire extinguishers?
Clear identification is strongly recommended so staff and visitors can quickly locate equipment in an emergency.
Appropriate extinguisher signage, consistent siting, and keeping equipment unobstructed should form part of your overall fire safety arrangements and risk assessment.
