8 Signs Your Business Needs New Fire Extinguishers
Fire extinguishers are a great first line of defence against small fires, but that line will be broken if one of yours isn’t working correctly.
Not only that, but fire extinguishers are a legal requirement in commercial properties, so keeping yours correctly maintained and knowing when they need replacing is key to keeping your business compliant with UK regulations.
The average lifespan of an extinguisher is between five and ten years, but many different factors can affect that, so you do need to actively keep on top of things. Even if they look fine on the outside, extinguishers can deteriorate internally, lose pressure and become unsafe. Read on and we’ll explain the importance of fire extinguisher servicing, eight signs your business needs new fire extinguishers and how we at Midland Fire can handle the supply and maintenance of your fire equipment.
So let’s get right to it.
Signs Your Fire Extinguishers Need Repairing or Replacing in 2026
- Age is beyond service life: Once an extinguisher passes its recommended lifespan, its components and internal chemicals may no longer work reliably when you need it, even if it looks fine. To find the age of your extinguisher, look for the date stamp printed on the extinguisher itself or on its label.
- Low pressure readings: If the needle’s in the red zone on the gauge, the extinguisher won’t discharge properly and won’t be able to put out a fire effectively.
- Visible corrosion or rusting: Rust or corrosion weakens the cylinder and can cause leaks or failure under pressure.
- Leaking valves or broken tamper seals: Any leaks or a missing tamper seal can be a sign of low pressure and could compromise the extinguisher’s ability to deliver the agent when needed.
- Damaged handles, pins or hoses: If any of the operating parts are damaged, the extinguisher may not work correctly in an emergency.
- Illegible labelling or missing instructions: If the label is unreadable, users won’t have the correct guidance on how to operate the extinguisher.
- Expired or missing inspection tags: Without valid inspection tags, there’s no assurance the extinguisher has been maintained and is still in proper working condition.
- The extinguisher has been used: Once an extinguisher has been discharged, even partially, it needs to be serviced or replaced to ensure it’s ready for the next emergency.
Legal Requirements for Fire Extinguisher Maintenance in the UK
According to The Regulatory Reform (Fire Safety) Order 2005 and The British Standard for fire extinguishers, BS 5306-3, a company’s responsible person should ensure that extinguishers are maintained regularly by a competent person.
Monthly in-house inspections as well as regular professional servicing will ensure that fire safety equipment is safe, reliable, efficient and fit for purpose. The maintenance intervals outlined in the regulations are as follows:
What Does Servicing and Maintenance Involve?
Monthly visual inspections
Each month, a visual inspection of your fire extinguishers should be carried out by the responsible person within your business. The monthly inspections should be recorded and any problems dealt with immediately. You need to do the following:
- Check for obvious damage like leaks, corrosion or signs that someone may have tampered with the extinguisher.
- Make sure they’re not obstructed so the extinguishers are visible and easy to find.
- Check their weight to make sure they feel full.
- Check the pressure dial – it should be pointing to green.
- Read the service labels to make sure they’re legible and nothing is missing.
- Check the handle and locking pins to make sure none are broken, missing or wobbly.
- Make sure the nozzle and hose aren’t blocked or torn.
Annual professional inspections
A yearly inspection needs to be carried out by a professional fire safety engineer on all your fire extinguishers. The following steps will be taken:
- Visual inspection for damage, corrosion and proper signage.
- Pressure and weight checks.
- Testing of discharge mechanisms.
- Replacement or repair of faulty components where necessary.
- Full replacement of the fire extinguisher if a repair is not possible.
- Recording of inspection, with the extinguisher tagged and dated for compliance.
- Extended servicing & overhaul every 5 – 10 years
- Fire extinguishers also need in-depth extended servicing within certain timeframes.
Powder, water and foam extinguishers need this service every five years, which includes a discharge test, valve overhaul, re-pressurising and refilling. CO2 extinguishers, due to their high-pressure cylinders, require a complete overhaul every ten years. This involves sending them to an approved centre for testing, performing a hydraulic (stretch) test and replacing the main valve.
Eventual replacement of fire extinguishers every 20 years
Even with the correct maintenance, all fire extinguishers will eventually need replacing. The lifespan can differ depending on the extinguisher, but all extinguishers need to be replaced after 20 years, regardless of their type or condition.
