What is Fire Extinguisher Maintenance?
Fire extinguisher maintenance is the routine inspection, testing, and servicing of portable fire extinguishers to ensure they remain in full working order. Carried out by a competent, trained engineer, the process covers everything from checking the physical condition of the extinguisher body to verifying that pressure levels, safety pins, and discharge mechanisms are functioning correctly. A dated service label is applied after each visit, providing a clear record of compliance for audit purposes.
In the UK, fire extinguisher maintenance is governed by BS 5306-3, the British Standard that sets out the requirements for the commissioning and maintenance of portable fire extinguishers. This standard defines the frequency of inspections, the checks that must be performed, and the circumstances under which an extinguisher should be replaced or recharged. Alongside this, the Regulatory Reform (Fire Safety) Order 2005 places a legal duty on responsible persons to keep all fire-fighting equipment in efficient working order, making professional servicing a practical and legal necessity rather than simply best practice.
It is worth noting that maintenance differs from a basic user check. While staff can and should visually inspect extinguishers on a monthly basis, the thorough annual service required by BS 5306-3 must be carried out by a competent engineer with the appropriate knowledge and equipment to identify faults that would not be visible to the untrained eye.
Why is Fire Extinguisher Maintenance Required?
The legal basis for fire extinguisher maintenance in non-domestic premises sits within the Regulatory Reform (Fire Safety) Order 2005. Under this legislation, the responsible person, typically the employer, building owner, or managing agent, must ensure that fire-fighting equipment provided on the premises is suitable, sufficient, and properly maintained. Failure to demonstrate compliance can result in enforcement action from the local fire authority, and in serious cases, prosecution. Just as understanding who is responsible for fire door maintenance is a key part of managing a building safely, knowing your obligations around extinguisher servicing is equally important.
Beyond the legal obligation, there is a straightforward safety case. A fire extinguisher that has not been serviced may have a depleted charge, a blocked nozzle, or a corroded body, any of which could cause it to fail at the moment it is needed most. Regular professional maintenance gives building occupants the best possible chance of responding effectively to a small fire before it escalates, and gives responsible persons the documented evidence they need to demonstrate due diligence to insurers and regulators alike.
What Does Fire Extinguisher Maintenance Involve?
During a professional service visit, a qualified engineer will inspect every extinguisher on site against the requirements set out in BS 5306-3. This includes a thorough examination of the cylinder body for signs of corrosion, denting, or damage; a check of the pressure gauge or indicator; an inspection of the hose, nozzle, and discharge mechanism; and verification that the safety pin and tamper seal are intact. Where an extended service or overhaul is due, the extinguisher may be discharged, internally examined, and recharged. The engineer will also confirm that the correct type of extinguisher is positioned in the right location for the hazards present in each area of the building.
At the end of the visit, each serviced extinguisher receives a new service label showing the date, the engineer’s details, and any remedial actions taken or recommended. You will also receive written documentation summarising the condition of your extinguishers, any units identified as requiring replacement, and confirmation that the service has been completed to the required standard. This paperwork forms a vital part of your fire safety records and will be required during any fire authority inspection or insurance review. If any extinguishers need replacing, London City Fire can supply the right units directly, and you can also buy fire extinguishers through us to ensure you have the correct coverage from the outset.

Who Needs Fire Extinguisher Maintenance?
In practical terms, any premises that holds fire extinguishers as part of its fire safety provision needs to have those extinguishers professionally maintained. This covers a wide range of building types including commercial offices, retail units, restaurants and hospitality venues, warehouses, schools, healthcare facilities, and places of worship. Residential blocks, particularly those managed under the Fire Safety Act 2021, also fall within scope where extinguishers are provided in common areas. Landlords, managing agents, housing associations, and property developers all have responsibilities in this area, and professional servicing is the most straightforward way to meet them.
Smaller businesses sometimes assume that fire extinguisher maintenance is only necessary for large or complex premises, but this is not the case. Even a single-unit business with just one or two extinguishers on site is required to have them serviced annually. The size of the business does not change the legal obligation. For those who are unsure whether their current extinguisher provision is adequate, a fire extinguisher quote from London City Fire will include a review of your coverage as well as a clear breakdown of servicing costs.

Frequently Asked Questions
Q: “How often does fire extinguisher maintenance need to be carried out?”
A: Under BS 5306-3, portable fire extinguishers should be serviced at least once every 12 months by a competent engineer. In addition, users should carry out a basic visual check each month to confirm the extinguisher is in its correct location, undamaged, and that the pressure indicator is in the green zone. Some extinguisher types also require an extended service or overhaul at specific intervals, typically every five years, which your engineer will advise on.
Q: “Who is legally responsible for fire extinguisher maintenance?”
A: Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person for the premises holds this duty. In most workplaces, this is the employer or building owner. For residential blocks and multi-occupancy buildings, it is typically the managing agent, landlord, or building owner. If you are unsure who holds responsibility for your specific premises, it is worth seeking guidance from a qualified fire safety professional.
Q: “What happens if I do not have my fire extinguishers maintained?”
A: Unmaintained extinguishers may fail to operate correctly in an emergency, putting the safety of building occupants at serious risk. From a legal standpoint, failure to maintain fire-fighting equipment in efficient working order is a breach of the Regulatory Reform (Fire Safety) Order 2005 and can result in enforcement action by the local fire and rescue authority. In more serious cases, prosecution may follow. Keeping extinguishers serviced and properly documented is one of the most straightforward steps a responsible person can take to demonstrate compliance.
Q: “How much does fire extinguisher maintenance cost?”
A: The cost of fire extinguisher servicing varies depending on the number of units on site, their type, and whether any remedial work or replacements are needed. London City Fire provides transparent, itemised quotes with no hidden charges. The best way to get an accurate figure for your premises is to get in touch directly, and we will put together a quote based on your specific requirements.
Q: “Do I need fire extinguisher maintenance for a small business?”
A: Yes. The legal requirement to maintain fire-fighting equipment applies regardless of the size of your business or the number of extinguishers you hold. Even if you only have one or two extinguishers on site, they must be serviced annually by a competent person and the service must be documented. Many small business owners find that arranging a combined service visit for all fire safety equipment, including extinguishers and fire alarm checks, is the most efficient way to stay compliant.
