2kg fire extinguisher buying guide

Updated: 20 October 2026

You are looking at a red cylinder that says 2 kg, and you still cannot tell whether it belongs in a flat, a van, or a holiday let. A 2kg fire extinguisher buying guide splits the charge weight from the fire rating, and it says who in the United Kingdom is obliged to keep one. The kilograms are the agent inside, not the size of the test fire. Prices and brackets sit on the [2 kg fire extinguisher comparison](/hub/fire-protection/fire-extinguisher-2kg). Peter F. compared four amazon.co.uk listings on 19 October 2026 and did not run a fire test. A qualifying purchase can earn us a commission at no extra cost to you.

What 2 kg does and does not tell you

A 2 kg extinguisher is a portable cylinder people buy for a van, a garage, or a small home. A 2 litre water-based unit sits in the same conversation because the cylinder is a similar handful, not because a litre equals a kilogram of powder. Under BS EN 3, a larger A number is a larger Class A test fire, and a larger B number is a larger Class B test fire. None of that is hiding inside the 2 kg line. None of the four saved listings here prints a 13A or 34B figure.

The marks worth reading

The about £19.99 listing is the only one in this set that states both BS EN 3-7:2004+A1:2007 and a Kitemark. DIN EN 3 on the Gloria listing is a German citation of the same family, not a BSI Kitemark. The best 2 kg fire extinguisher page matches that listing to a driver who wants the branded car shape. Navpower's title claims RINA and MED and does not print BS EN 3. Firexo's bullets say EN3 and a wider class list than the manufacturer's 2 litre page, which limits BS EN 3-7 to A, B, and F plus electrical fires up to 1000 V at 1 metre. The 13A, 34B, and 25F figures live on that manufacturer page, not in the Amazon saved listing.

Home, holiday let, and workplace

A private home in England and Wales does not have to keep a fire extinguisher. Article 6 of the Regulatory Reform (Fire Safety) Order 2005 takes ordinary domestic premises outside that Order. Scotland and Northern Ireland also leave an ordinary house outside the main duty. The duty starts for a workplace, common parts of flats, and many holiday lets. The Fire Protection Association, quoting BS 5306-8, warns that powder used indoors can wreck visibility unless a risk assessment says otherwise.

What to check before you pay

If the fire rating is absent, as it is on all four saved listings here, you are buying a weight and a class letter, not a measured test fire. Do not promote DIN EN 3, or a RINA line in a title, into a Kitemark. Firexo reviews include a pin and tamper seal already off. Navpower reviews include cylinders described as empty. Gloria reviews include a gauge described as showing no pressure. If the cylinder will travel, the bracket has to be a vehicle bracket, which is the 2 kg fire extinguisher for a car. About £90 is a pack of two 2 litre units, not a certificate for every fuel.

Common questions

What is the difference between 2 kg and 13A 34B?
2 kg is the mass of the agent in the cylinder. 13A 34B is a fire rating: the size of Class A and Class B test fires that model achieved under BS EN 3. A bigger number is a bigger test fire, not a better star score. Two 2 kg powders can carry different ratings. Jactone lists one trade model as 13A 70B C. That figure is not the rating of the four listings here, because those saved listings do not print a number.
Is a Kitemark the same as a star rating?
No. A Kitemark is a BSI certification mark against a standard such as BS EN 3. A star rating is the average of amazon.co.uk customer reviews. The about £19.99 powder states a Kitemark and also shows 4.8 from 89 reviews. Those are two different facts. Reviewers on that listing have generally not used the extinguisher on a fire, so the stars do not confirm the test behind the mark.
When does a workplace have to commission a cylinder bought online?
When the premises are covered by fire-safety law, paying for the cylinder is not the end of the job. The responsible person has it commissioned and kept maintained. BAFE's reading of BS 5306-3 is a monthly look and a basic service by a competent person about every 12 months. An online listing with no fire rating and no service history is not commissioned because a driver delivered it.
How often is a basic service due?
About every 12 months, where BS 5306-3 is the regime you are following, plus a look each month at the gauge, the pin, and the seal. Powder then has a longer extended service, every five years, or every ten years if it is primary-sealed. A private home is not under that duty. A gauge that has already left the green is still a reason to stop trusting the cylinder, including at home.
Is DIN EN 3 on the Gloria listing a UK Kitemark?
No. The Gloria P2 GM listing cites DIN EN 3. A BSI Kitemark is not stated, and the saved listing has no UK star line. DIN EN 3 points at the European standard as it is cited in Germany. It does not, by itself, show that this amazon.co.uk page carries a Kitemark. Check the label photograph before you treat the two phrases as the same thing.
