What is fire extinguisher maintenance?
Fire extinguisher maintenance is more than a quick visual check.
It’s a structured series of inspections carried out by a BAFE qualified engineer to make sure your extinguishers:
- are suitable for the fire risks in your building and location
- are fully operational and ready to use
- will perform exactly as expected in an emergency
What’s included in fire extinguisher maintenance?
Every check is methodical. Every detail matters.
Our engineers follow a clear process to guarantee safety, reliability and compliance, including:
- visual inspection for damage, corrosion or tampering
- pressure gauge checks to confirm safe operating levels
- inspection of the discharge hose for blockages or wear
- confirmation the extinguisher is securely mounted and easily accessible

Our service goes beyond the basics, giving you peace of mind that your equipment will work when it’s needed most – wherever you operate across the UK.
installing the right one for your premises
Fire extinguishers come in various types, each designed to combat specific types of fire. Choosing the right fire extinguisher for your premises is crucial for effective fire protection.
At Mitie Fire & Security, our qualified engineers ensure that the correct extinguishers are installed based on the unique fire risks in your environment.
- Water Extinguishers
Designed to target Class A fires, including paper, wood, cloth, straw and textiles.
- Foam Extinguishers
Designed to target Class A and Class B fires, including liquid spill fires such as petrol, oil, fats and paints.
- Powder Extinguishers
Designed to combat mixed fire risk environments. Suitable for combating flammable liquid risk, such as methane, propane, hydrogen and natural gas fires. M28 and L2 Powder Extinguishers are best for tackling metal fires.
- Carbon Dioxide Extinguishers
Designed to target Class B fires particularly electrical hazards. Carbon Dioxide is harmless to electrical equipment and is ideal for modern offices, electronic risks, and fires caused by the combustion of liquids such as oils, fats and solvents.
- Wet Chemical Extinguishers
Designed for Class F fires, particularly flammable cooking oils such as sunflower oil, animal fats or olive oil. This extinguisher is also effective against Class A fires.
- Lithium Battery Extinguisher
Conventional fire extinguishers cannot effectively extinguish a lithium-ion battery fire. Only a specialist extinguisher such as the LFX extinguisher is suitable on this type of fire.
Why are there different extinguisher types?
Because the wrong choice can make things worse.
Different fires require different suppression methods. Using the wrong extinguisher can increase risk – from electrocution during electrical fires to ineffective suppression of gas or liquid fires.
That’s why we assess every building individually. From kitchens and plant rooms to offices and storage areas, we make sure your extinguishers match the real risks on site.
How do engineers choose?
Our fire extinguisher service includes a detailed assessment, considering:
- Fire risk classification
Identifying hazards such as solid combustibles, flammable liquids or electrical equipment.
- Environment and usage
Indoor or outdoor use. Accessibility. Operating conditions.
- Regulatory compliance
Ensuring full compliance with BS 5306-3 and UK fire safety legislation.
- Ease of use
Selecting extinguishers that can be operated quickly and confidently in an emergency.
Why is regular fire extinguisher maintenance important?
Regular maintenance is a legal requirement under the Regulatory Reform (Fire Safety) Order 2005 and BS 5306-3 — but it’s also essential for keeping people safe.
Our maintenance checks cover
- pressure and operational integrity
- handles, nozzles and discharge hoses
- corrosion, dents and physical damage
- tamper seals, misuse and accidental discharge
- mounting, access and obstructions
- refilling, replacement and expiry checks
- full compliance verification

FAQ: Fire Extinguisher Services
Who should carry out fire extinguisher maintenance?
Fire extinguisher maintenance must be carried out by a qualified, competent engineer.
At Mitie Fire & Security, all servicing is completed by BAFE-certified engineers who are trained to carry out thorough checks on all types of fire extinguishers. Our engineers are third-party examined and accredited, ensuring every service meets current British Standards and remains fit for purpose.
How often should fire extinguisher maintenance be carried out?
Fire extinguishers must be serviced annually, with additional extended servicing depending on the extinguisher type.
Annual servicing
In line with BS 5306-3 (2017), all fire extinguishers should be serviced at least once a year by a qualified, BAFE-certified engineer. This ensures legal compliance and confirms your extinguishers will operate correctly in an emergency.
Extended servicing every 5–10 years
Some extinguishers require more in-depth servicing at set intervals:
- Water, foam and powder extinguishers require an extended service every 5 years, including full discharge, internal inspection and refill
- CO₂ extinguishers require testing and refilling every 10 years due to their high-pressure construction
In addition, monthly visual checks should be carried out on site by the designated Responsible Person to spot obvious issues such as damage, pressure loss or tampering.
How often should fire extinguishers be serviced?
Fire extinguishers should be serviced once a year by a qualified engineer.
Alongside annual servicing, monthly visual inspections by the Responsible Person help identify visible damage, pressure changes or signs of misuse between engineer visits.
Who is responsible for fire extinguisher maintenance?
The responsibility sits with the business owner or designated Responsible Person.
Under UK fire safety legislation, they must ensure extinguishers are maintained correctly and that service records are kept as evidence of compliance with fire safety requirements.
Do I need to be qualified to perform fire extinguisher maintenance?
Yes. Fire extinguisher maintenance must only be carried out by a qualified engineer.
While the Responsible Person can complete monthly visual checks, annual and extended servicing must be completed by a competent, accredited professional to ensure safety, compliance and reliability.
Why are you transitioning to fluorine-free foam extinguishers?
We are transitioning to fluorine-free foam extinguishers to reduce environmental impact and stay ahead of legislation.
Traditional foam extinguishers can contain PFAS chemicals, including PFHxA, which persist in the environment and pose long-term risks. By moving to fluorine-free alternatives, we’re taking proactive steps to protect people and the planet while continuing to deliver effective fire protection and regulatory compliance.
