Fire Extinguishers: Your Legal Obligations (UK Compliance Guide for Businesses)

Highlights

• Fire extinguishers are a legal requirement where your fire risk assessment shows they are needed in order to protect relevant persons. In England and Wales, this duty sits under the Regulatory Reform (Fire Safety) Order 2005. 
• The legal duty falls on the Responsible Person, which may be the employer, owner, landlord, occupier or another person with control of the premises.
• Extinguishers must be suitable for the risks present, easy to reach, simple to use, and signed where necessary. 
• To comply in practice, businesses typically follow BS 5306, with monthly visual inspections by the Responsible Person and annual servicing by a competent person. 
• Staff must receive fire safety instruction and training, with additional training for employees who have specific fire safety duties. 
• Non-compliance can lead to enforcement notices, prohibition notices, prosecution, unlimited fines and up to two years’ imprisonment in serious cases. 

Introduction

Fire extinguisher requirements for UK businesses need to be understood as an important criterion, rather than optional. If your premises present fire risks, the law requires appropriate fire-fighting equipment, supported by a suitable fire risk assessment, proper maintenance, staff training and clear emergency procedures. 

In England and Wales, the main law is the Regulatory Reform (Fire Safety) Order 2005, while BS 5306 provides the recognised code of practice for selection, positioning and servicing. 

Hence, business owners should be considerate in choosing the right extinguishers, keep them serviceable, train their people, and document what they do. 

What Are the Legal Requirements for Fire Extinguishers?

UK law requires businesses to provide appropriate fire-fighting equipment where it is necessary to protect people on the premises. Under the Regulatory Reform (Fire Safety) Order 2005, the Responsible Person must assess the fire risks and put in place suitable fire precautions. That includes extinguishers where they are needed because of the building layout, activities carried out, hazards present, substances used, or the number of people on site. 

The law requires equipment that is appropriate to the premises and the risks of every business. 

Businesses usually follow BS 5306-8 for selection and siting, and BS 5306-3 for maintenance and servicing. These standards are widely used to demonstrate good practice and workplace fire safety compliance. 

Who Is Responsible for Fire Extinguisher Compliance?

The Responsible Person is legally accountable for fire extinguisher compliance. In a workplace, that is usually the employer if the workplace is under their control. 

In other premises, it may be the owner, landlord, occupier, managing agent, facilities manager or another person with control of the premises. If more than one Responsible Person exists, they must co-operate and co-ordinate. 

The Responsible Person’s fire safety duty includes:

• Carrying out and reviewing the fire risk assessment
• Providing suitable extinguishers and related fire safety measures
• Maintaining equipment in efficient working order
• Planning emergency procedures
• Giving staff information, instruction and training
• Appointing competent people where needed to help manage fire safety

Fire Extinguisher Installation Requirements

Fire extinguishers must match the actual fire risks on your site and be positioned where people can reach them quickly. The Fire Safety Order requires appropriate fire-fighting equipment, and the official offices and shops guidance explains that selection should follow risk assessment rather than guesswork. 

Choosing the Correct Extinguisher Type

Different fire risks call for different extinguishers:

• Class A: ordinary combustibles such as paper, wood and textiles
• Class B: flammable liquids
• Class C: flammable gases
• Electrical risks: commonly covered with CO2 where suitable
• Class F: cooking oils and fats, especially in commercial kitchens

Typical provision benchmarks

For standard Class A fire risks in offices and shops, official guidance says that one water-based extinguisher for approximately every 200m² of floor space, with a minimum of two extinguishers per floor, will normally be adequate. That is guidance, and it should always be checked against your fire risk assessment. 

Positioning rules

Extinguishers should usually be:

• On escape routes
• Close to room exits, floor exits or final exits
• Near specific hazards such as flammable liquids or cooking equipment
• Located so people ideally travel no more than 30 metres to reach one
• Mounted on a wall or dedicated stand at a practical height

Maintenance & Inspection Requirements

Fire extinguisher maintenance requirements are ongoing. The law requires a suitable system of maintenance, so fire safety equipment remains efficient, in working order and in good repair. In practice, businesses usually evidence compliance by following BS 5306-3. 

1. Monthly visual checks

The Responsible Person should carry out visual inspections at least once a month. BAFE’s summary of BS 5306-3 states that visual inspections should be carried out at least monthly, and more often where circumstances require. 

A monthly check should confirm:

• The extinguisher is in the correct location
• Access is unobstructed
• The unit has not been discharged, damaged or tampered with
• The pressure indicator, where fitted, is in the safe range
• The instructions remain legible

2. Annual servicing

Portable extinguishers should receive a basic service at least annually by a competent person. GOV.UK’s fire risk assessment checklist also expects annual maintenance of extinguishers and records of testing and maintenance. 

Extended servicing

BS 5306-3 also sets longer-interval servicing requirements. Water-based and many powder extinguishers generally require extended service every five years, while CO2 and some other types require overhaul or extended service every ten years, depending on extinguisher type.

Signage, Accessibility & Positioning Rules

Extinguishers must be easy to find, easy to access and clearly indicated where necessary. Article 13 says non-automatic fire-fighting equipment must be easily accessible, simple to use and indicated by signs.

Furthermore, Extinguishers should be visible, not blocked by stock or furniture, and mounted so the handle is roughly 1 metre from the floor for larger units and 1.5 metres for smaller units. That makes them easier to locate and lift in an emergency. 

Signage is more nuanced than many businesses realise. If the location of firefighting equipment is readily apparent and visible at all times, signs may not be necessary. In other situations, your fire risk assessment is likely to show that signage is required.

Training Requirements for Employees

Employees must receive fire safety training, and extinguisher-use training should be given where appropriate. Staff must receive adequate safety training when they start work, when risks change, and periodically, where appropriate. 

The training must cover the precautions and actions needed to protect themselves and others, and it must take place during working hours. 

Basic staff instruction should cover:

• The alarm and evacuation procedure
• The location of exits and assembly points
• How to identify extinguisher types
• When not to use an extinguisher
• Simple operating guidance, such as the PASS method (Pull, Aim, Squeeze, Sweep)

Record Keeping & Documentation

Good documentation is essential evidence of workplace fire safety compliance. Article 9 requires the Responsible Person to record the significant findings of the fire risk assessment where they employ five or more people, where a licence is in force, or where an alterations notice applies. 

The assessment must also be reviewed regularly and updated when circumstances change.

Consequences of Non-Compliance

Ignoring fire extinguisher compliance can trigger enforcement action, prosecution and serious business disruption. Fire and rescue authorities can inspect premises, issue informal advice, serve formal fire safety notices, and require improvements through enforcement notices.

Where risk is severe, they can serve a prohibition notice that takes effect immediately and restricts or prohibits use of the premises. That is the closest equivalent to a forced closure, and it can have an immediate operational impact on your business.
