If you manage a commercial property or public building, you’ve likely asked yourself: Do fire extinguishers expire? The short answer is yes — and understanding the rules around this is crucial for compliance, safety, and insurance.

In this guide, we’ll explain how long fire extinguishers last, UK laws you need to follow, and how to stay protected with regular servicing.

How Long Do Fire Extinguishers Last in the UK?

In the UK, most fire extinguishers have a lifespan of 5 to 15 years, depending on the type, manufacturer, and usage. However, just because a unit hasn’t been used doesn’t mean it’s safe to keep.

Key signs an extinguisher may be expired or unsafe include:

  • Missing or unreadable labels
  • Damaged hoses or nozzles
  • Rust or corrosion
  • Low pressure readings
  • Expired service tags

If your extinguisher shows any of these signs — even if it’s “in date” — it should be replaced or serviced by a professional.

UK Fire Extinguisher Regulations for Businesses

Under the Regulatory Reform (Fire Safety) Order 2005, employers and building owners are legally responsible for:

  • Providing suitable fire-fighting equipment
  • Maintaining that equipment in working condition
  • Ensuring regular servicing and checks

BS 5306-3:2017 provides the standard for extinguisher maintenance and servicing in the UK. It states that all extinguishers must be:

  • Visually inspected monthly
  • Serviced annually by a competent technician
  • Pressure-tested (extended service) every 5 years for water, foam, and powder types
  • Replaced every 10 years for CO₂ extinguishers, as they cannot be refilled or pressure tested

Failure to follow these guidelines can result in fines, invalidated insurance, or more serious consequences in the event of a fire.

Do Fire Extinguishers Really Expire?

Technically, extinguishers don't have an “expiry date” printed on the canister — but they do have a manufacturer’s date and a maximum serviceable lifespan. Once that lifespan passes or the unit fails a service check, it must be replaced.

That’s why fire extinguisher servicing is so important: it identifies faults before they become dangerous or non-compliant.

How to Tell If Your Extinguishers Need Replacing

Ask yourself:

  1. Has the extinguisher been serviced in the last 12 months?
  2. Is it more than 10 years old?
  3. Does it show visible damage or corrosion?
  4. Is the pressure gauge in the green?

If the answer to any of these is no — it's time to book a service or replacement.
