How Much Does Fire Extinguisher Servicing Cost?

When you’re running a business, managing a property, or taking care of a premises’ safety responsibilities, one of the practical questions you’ll eventually ask is:

“How much does it actually cost to service fire extinguishers?”

It’s a fair question—and like most things in fire safety, the answer depends on a few key factors.

But don’t worry—we’ll walk you through the typical costs involved and what to look out for, so you can budget smartly and stay compliant.

Whether you’re in Farnborough, Camberley, Reading, Guildford, or anywhere across Hampshire, Surrey, or Berkshire, here’s what you need to know.

The Short Answer

As a general guide:

🔧 Basic annual servicing of fire extinguishers usually costs between £7 and £15 per unit, depending on:

• The type of extinguisher (e.g. water, foam, CO₂)
• The number of extinguishers on site
• Whether any parts or refills are required
• Travel distance or call-out charges

Many fire safety companies (including ESI) offer fixed-price servicing packages or discounts for multiple extinguishers, which helps you stay on top of costs.

What’s Included in Annual Servicing?

Annual servicing, carried out in line with BS 5306-3, includes:

✅ Checking the pressure and weight
✅ Inspecting for damage, corrosion or leakage
✅ Verifying the safety pin and tamper seal
✅ Confirming accessibility and correct placement
✅ Cleaning the unit and updating labels
✅ Recording everything in your fire safety logbook

This servicing must be done by a competent person, not just for legal compliance, but also to ensure the extinguisher will work when you need it.

At ESI, we only use fully qualified engineers—trained to the latest standards and fully insured.

Extra Costs to Consider

While the basic service cost is predictable, some additional costs may apply depending on the condition or age of your extinguishers:

🔁 Replacement parts

• O-rings, seals, pins, and hoses may need replacing
• These are usually a few pounds per part

🧯 Refills or recharges

• If your extinguisher has been used or has lost pressure, it may need refilling
• Refilling costs can range from £10 to £25, depending on the type

🔧 Extended servicing (every 5 years)

• Water, foam, and powder extinguishers need a full discharge, internal inspection, and recharge at year 5
• This extended service can cost £20 to £60 per unit
• At this point, some customers choose to replace the unit entirely, which can often be more cost-effective

🚫 Non-compliant or expired extinguishers

• If an extinguisher is damaged, the wrong type, or over 10 years old, it may need replacing
• New extinguishers typically cost between £30 and £120 depending on the type and size

How Many Extinguishers Do You Need?

Another factor in your overall cost is how many extinguishers your premises requires, which is influenced by:

• The size and layout of the building
• The types of risks present (e.g. electrical, flammable liquids, kitchen equipment)
• The travel distance to reach an extinguisher (usually no more than 30 metres)

As part of our service, ESI can carry out a full fire extinguisher audit and help you understand if you have the right number and type, properly positioned, for your space.
