Fire extinguishers are often the first line of defence when a fire breaks out in the workplace. When used quickly and correctly, they can prevent a small incident turning into a major emergency. However, a fire extinguisher that has not been properly serviced is unreliable at best and dangerous at worst.

In this complete guide, we explain everything UK organisations need to know about fire extinguisher servicing, the legal responsibilities involved, and how Morgan Fire helps businesses, schools and commercial property managers stay compliant and protected.

Why Fire Extinguisher Servicing Matters

It is easy to assume that because a fire extinguisher is hanging on the wall, it will work when needed. In reality, extinguishers are mechanical devices that can lose pressure, become blocked, or deteriorate internally over time.

If an extinguisher fails in an emergency:

  • Staff may be put at serious risk

  • A manageable fire can rapidly spread

  • Evacuation routes may become blocked

  • Property damage and downtime increase dramatically

Regular servicing ensures that every extinguisher on your premises is safe, charged correctly and ready for use.

What the Law Says in the UK

Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must ensure that fire-fighting equipment is:

  • Suitable for the risks in the building

  • Properly maintained

  • Easily accessible and clearly identified

British Standard BS 5306 further explains how fire extinguishers should be selected, installed, inspected and serviced.

Failing to maintain extinguishers is not a minor oversight – it is a breach of fire safety legislation and can result in enforcement action.

Types of Fire Extinguishers and Their Uses

Different types of extinguishers are designed to tackle different fire classes. Common examples include:

  • Water extinguishers – for paper, wood and textiles

  • Foam extinguishers – for flammable liquids such as petrol or paint

  • CO₂ extinguishers – for electrical fires

  • Dry powder extinguishers – for mixed risks including gases

  • Wet chemical extinguishers – for commercial kitchens

Correct selection is just as important as servicing. Morgan Fire ensures your extinguishers are suitable for the specific risks in your building.

What Does Fire Extinguisher Servicing Involve?

Fire extinguisher maintenance is not simply a quick glance at the gauge. A proper service includes a number of checks.

1. Visual Inspection

This ensures:

  • The extinguisher is in its correct location

  • There is no physical damage or corrosion

  • Instructions are legible

  • The pressure gauge is in the green zone

  • The safety pin and tamper seal are intact

2. Annual Basic Service

This is carried out by a competent engineer and involves:

  • Checking internal pressure or weight

  • Inspecting internal components where possible

  • Ensuring hoses and nozzles are clear

  • Replacing faulty parts if needed

  • Updating service labels and documentation

3. Extended Service or Overhaul

At set intervals (usually every 5 or 10 years depending on the extinguisher type), extinguishers must undergo more in-depth maintenance, including discharge testing or internal examination.

How Often Should Extinguishers Be Serviced?

In most commercial settings, extinguishers must be:

  • Visually checked regularly by in-house staff

  • Serviced annually by a competent professional

  • Overhauled or replaced according to manufacturer and British Standard guidelines

Morgan Fire offers structured servicing schedules to ensure nothing is missed.

Who Can Service Fire Extinguishers?

Servicing must be carried out by a trained and competent engineer. This is not something that should be done by unqualified staff.

Morgan Fire’s technicians are fully trained and experienced in servicing extinguishers across a wide range of sectors, from schools and offices to warehouses and healthcare environments.

Common Fire Extinguisher Issues

Some of the most frequent problems discovered during servicing include:

  • Loss of pressure

  • Blocked discharge horns

  • Corrosion inside the cylinder

  • Incorrect extinguisher types for the risk

  • Units missing or removed from their brackets

These issues often go unnoticed until a professional inspection takes place.
