How to Choose the Best Fire Extinguisher for Your Home in 2026
We all want to feel safe at home, so we try to be prepared for any possible scenario. One of the most critical steps we must take is to purchase a proper fire extinguisher. But when there are so many different fire extinguishers on the market, how do you know which one to buy?
Don’t worry; we’ve got you covered. This article will review the various types of fire extinguishers, the minimum recommendations for domestic use, and the regulations required by the authorities. And we will help you find the best fire extinguisher for home use.
Who are the Fire Safety Authorities in Your Area of Residence?
Different authorities are responsible for fire and safety regulations in different parts of the UK. Your premises must have the appropriate extinguishers, or you risk failing to meet current regulations.
The Regulatory Reform (Fire Safety) Order 2005 governs general fire safety in England and Wales.
Part 3 of the Fire (Scotland) Act 2005 covers general fire safety requirements, supplemented by the Fire Safety (Scotland) Regulations 2006.
Local fire and rescue authorities enforce this fire safety legislation on most premises. HSE oversees enforcement on construction sites and ships being built or repaired.
Types of Fire
Before we discuss the different types of fire extinguishers, let’s review the main scenarios in which they might be used.
- Class A: solid materials such as wood or paper, fabric, and some plastics
- Class B: liquids or gas such as alcohol, ether, gasoline, or grease
- Class C: electrical failure from appliances, electronic equipment, and wiring
- Class D: metallic substances such as sodium, titanium, zirconium, or magnesium
- Class K: grease or oil fires, specifically from cooking
Types of Fire Extinguishers
The five primary types of fire extinguishers are water, foam, dry powder, CO2, and wet chemicals. In addition to choosing the right type, you must consider the correct sizes and weights.
Water Fire Extinguisher
Water extinguishers were the first fire extinguishers and remain one of the most commonly used ones today. They can be identified by the WHITE-coloured label stating ‘Water’.
Standard water fire extinguishers only work on fires involving flammable solids. As mentioned above, fires involving flammable solids, such as paper, wood, and textiles, are ‘class A’.
Sizes available: 3 litres, 6 litres, and 9 litres
Application
| USE ON | DO NOT USE ON |
|---|---|
| Class “A” Fires- Flammable solids, such as paper, wood, and textiles, which are ‘class A’. | Electrical fires – they are extremely dangerous and could result in electrocution. Fires caused by flammable liquids such as fuel and paint (‘class B’ fires) Fires caused by flammable gases like methane and butane (‘class C’ fires) Oil and grease-related cooking fires, such as chip pan fires (‘class F’ fires) |
Foam Fire Extinguisher
A foam fire extinguisher is suitable for the majority of commercial premises. They are typically used to extinguish fires involving flammable solids and liquids.
They are distinguished by a CREAM-coloured label on the body that reads ‘Foam’.
Sizes available: 2 litres, 3 litres, 6 litres, and 9 litres.
Application
| USE ON | DO NOT USE ON |
|---|---|
Fires involving flammable solids, such as paper, wood, and textiles (‘class A’ fires) Fires involving some flammable liquids, such as petrol, diesel, and paint (‘class B’ fires) Fires involving electrical appliances IF the extinguisher has passed the 35kv conductivity test | A foam fire extinguisher is good for general use but is not specifically designed for electrical fires. |
Dry Powder Fire Extinguisher
There are two types of dry powder fire extinguishers – standard and special.
Almost any type of fire can be extinguished using a standard dry powder fire extinguisher. They are not
advised for use in confined areas, though.
Specialist dry powder extinguishers are used on fires involving flammable metal, lithium (L2 powder extinguishers only) and other flammable metals (M28 powder extinguishers only).
These fire extinguishers are also known as ABC fire extinguishers, multi-purpose fire extinguishers and dry chemical fire extinguishers. They can be distinguished by a BLUE-coloured label stating ‘Powder’.
Sizes available: 1 kg, 2 kg, 3 kg, 6 kg and 9 kg.
Application
| USE ON | DO NOT USE ON |
|---|---|
Standard dry powder extinguishers Fires involving flammable solids, such as paper, wood, and textiles (‘class A’ fires) Fires involving flammable liquids, such as petrol, diesel, and paint (‘class B’ fires) Fires involving flammable gases, such as butane and methane (‘class C’ fires) Electrical fires involving electrical equipment up to 1000v Specialist dry powder extinguishers Fires involving the flammable metal lithium (L2 powder extinguishers only) Fires involving all other flammable metals (M28 powder extinguishers only) | Fires involving cooking oil, such as chip pan fires (‘class F’ fires) Fires involving electrical equipment over 1000v Fires in enclosed spaces Fires involving flammable metals UNLESS it is a specialist dry powder extinguisher |
CO₂ Fire Extinguisher
The preferred extinguisher for electrical fires is a CO₂ extinguisher. They also work on flammable liquid (class B) fires. The term “carbon dioxide extinguishers” or “carbon dioxide extinguishers” may also be used to refer to them.
They can be distinguished by a BLACK-coloured label stating ‘CO₂’ and nozzle ends in a distinctive black ‘horn’.
Sizes available: 2kg and 5kg
Application
| USE ON | DO NOT USE ON |
|---|---|
Fires involving equipment such as computers, or generators (‘electrical’ fires) Fires involving some flammable liquids, such as petrol, diesel, and paint (‘class B’ fires) | Cooking fires involving oil and grease, such as chip pan fires (‘class F’ fires) |
Wet Chemicals Fire Extinguisher
Wet chemical extinguishers are one of the less well-known extinguisher types. Only wet chemical fire extinguishers are advised for use on cooking oil fires, and they are a crucial component of any professional kitchen’s safety supply kit. Additionally, they are referred to as “Class F” and “Class ABF” fire extinguishers.
They can be distinguished by a YELLOW-coloured label stating ‘Wet Chemical’ and a longer-than-usual hose with a ‘lance’ attachment.
Sizes available: 2 litres, 3 litres and 6 litres
Application
| USE ON | DO NOT USE ON |
|---|---|
Fires involving cooking oils and fats, such as lard, olive oil, butter and vegetable oil (‘class F’ fires) Fires involving flammable solids, such as paper, wood, and textiles (‘class A’ fires) Some wet chemical fire extinguishers are also cleared for use on class B fires – those involving flammable liquids, such as petrol, diesel, and paint. Check the label or ask your fire safety professional before using wet chemical extinguishers on this type of fire. | Fires involving flammable liquids (‘class B’ fires) UNLESS they are specifically cleared for this use Fires involving flammable gases, such as methane and butane (‘class C’ fires) Electrical fires |
What is the best fire extinguisher for home use?
Powder fire extinguishers are the most often recommended home fire extinguishers.
These fire extinguishers spray a chemical-based powder that efficiently douses flames and puts out the fire’s source. Powder fire extinguishers are also called ABC extinguishers because they can be used in fire classes A, B, and C.
Due to the chemicals in the powder used in these types of fire extinguishers, some surfaces in the home may be damaged. In an emergency, using powder fire extinguishers can also reduce visibility.
Using a 1 kg dry powder extinguisher is advised for domestic purposes. The fire is too big if it cannot be put out with a 1 kg extinguisher. Everyone should leave the house immediately, and you should dial 999.

FAQ
How do I use a fire extinguisher?
Remember the acronym “PASS”:
P – Pull: Pull the pin to unlock the extinguisher.
A – Aim: Aim the nozzle at the base of the fire.
S – Squeeze: Squeeze the handle to release the extinguishing agent.
S – Sweep: Sweep from side to side until the fire is out.
How often should I inspect my fire extinguisher?
Regularly inspect your fire extinguisher to ensure it is in good working condition. Check the pressure gauge, inspect for physical damage, and ensure the pull pin is intact. Follow the manufacturer’s guidelines for maintenance.
Can I recharge a fire extinguisher myself?
It’s recommended to have a professional fire extinguisher service provider handle recharging. They can also perform any necessary maintenance or repairs.
Where should I place fire extinguishers in my home?
Install fire extinguishers in easily accessible locations, such as the kitchen, garage, and bedrooms. Mount them on the wall at eye level and ensure everyone in the household knows their location
How long does a fire extinguisher typically last?
Most standard fire extinguishers have a lifespan of around 10 to 12 years. However, this depends heavily on the extinguisher type and whether it has been well-maintained. You should visually inspect the pressure gauge monthly to ensure the needle remains in the green zone. Even if an extinguisher has never been used, its internal seals can degrade over time, causing it to lose pressure.
What do the different colour codes on fire extinguishers mean?
In the UK, all modern fire extinguishers are painted red, but they feature a specific colour band or label to quickly identify the extinguishing agent inside. Knowing these colours is vital in an emergency:
Red (or White label): Water
Cream label: Foam
Blue label: Dry Powder
Black label: CO₂
Yellow label: Wet Chemical
Should I use a fire blanket instead of an extinguisher in the kitchen?
For most domestic kitchens, it is highly recommended to have both. A fire blanket is often the safest and most effective way to smother small pan fires without splashing or spreading hot oil. If you do opt for an extinguisher in the kitchen, it must be a Wet Chemical extinguisher (Yellow label) specifically designed for cooking oils and fats. Never use a standard water or foam extinguisher on a cooking oil fire.
How do I safely dispose of an old or expired fire extinguisher?
Because fire extinguishers are pressurised, you cannot simply throw them in your standard household bin. If your extinguisher is out of date or depressurised, you should take it to your local council recycling centre (many have dedicated hazardous waste sections for pressurised containers). Alternatively, if you are having a new extinguisher installed by a fire safety professional, they will often take the old one away for safe disposal.
Is it safe to use a dry powder extinguisher indoors?
While a 1kg dry powder extinguisher is frequently recommended as a versatile multi-purpose option for homes, it should be used with caution in small, unventilated rooms. Discharging a powder extinguisher indoors can significantly reduce visibility, and the powder can cause respiratory irritation, which might impede your escape route. If you have to use one indoors, ensure everyone else has evacuated and you have a clear path to the nearest exit.
