F2 vs F3 Fireworks: What's the Difference and Which Do You Need?

What Do F2 and F3 Actually Mean?

F2 and F3 are safety categories set by European (and now UK) regulations. They tell you one thing: the minimum distance between the firework and your audience.

• F2 — 8-metre safety distance. Designed for outdoor use in reasonably confined areas. These are your garden fireworks.
• F3 — 25-metre safety distance. Designed for outdoor use in large open areas. These are your display fireworks.

That's it. The category doesn't tell you how loud a firework is, how high it goes, or how much explosive content it has. It's purely about how far away people need to stand.

For completeness: F1 covers indoor fireworks like ice fountains and fun snaps. F4 covers professional display fireworks that require a firing licence — we don't sell those.

Category vs Classification — Why People Get Confused

This is the single biggest source of confusion in fireworks, so let's clear it up.

Category (F2/F3) and classification (1.3G/1.4G) are two completely separate systems. They measure different things and they don't line up the way most people assume.

• Category (F1–F4) = safety distance. How far to stand back.
• Classification (1.3G/1.4G) = UN transport hazard rating. Based on the net explosive content inside the firework.

Here's where it gets interesting: a firework can be F2 category and 1.3G classified. It can also be F3 category and 1.4G classified. The two systems are independent. An F2 cake with 1.3G classification has a higher explosive content per unit but still only needs 8 metres of clearance. An F3 rocket with 1.4G classification has a lower explosive content but needs 25 metres because of how high and far it travels.

The takeaway: don't assume 1.3G means "professional" or that 1.4G means "garden safe." Check the category label for your safety distance, and check the classification if you're interested in the explosive characteristics.

Which Fireworks Are F2?

Most of the fireworks we sell are F2. Roughly 60% of our range falls into this category. F2 fireworks include:

• Cakes and barrages — smaller bore sizes (under 25mm) tend to be F2. These are the workhorses of any garden display.
• Fountains — the majority are F2. Low-level effects that work well in tighter spaces.
• Roman candles — most single-tube candles and smaller batteries are F2.
• Sparklers — all F2 (or F1 for indoor sparklers).
• Catherine wheels — most are F2, except the larger 4 Point Silver Wheel.
• Selection boxes — smaller boxes are predominantly F2 items, though larger boxes may include some F3 pieces.

F2 fireworks work in a standard back garden. If you can stand 8 metres from the firing point and keep spectators behind that line, you're good. That's roughly the length of a large car and a half.

Which Fireworks Are F3?

F3 fireworks are the bigger, more powerful pieces. They make up around 30–35% of our range and include:

• Larger cakes — bigger bore sizes (30mm+), heavier powder loads, higher-reaching effects.
• Compounds — most compounds are F3. These are the multi-cake display pieces like Perpetual Motion (600 shots, 4+ minutes) and High Roller (100 shots, 24 seconds of pure intensity).
• Rockets — the majority of rockets are F3 because of the height they reach.
• Mines — both mines in our range are F3.
• Larger candle batteries — multi-tube batteries with higher shot counts.

You need 25 metres between the firework and your audience. That's about the length of a standard swimming pool, or roughly 80 feet. If your garden is smaller than that, stick with F2 pieces or find a larger open space.

Can I Use F3 Fireworks in My Garden?

You can, provided your garden (or the space you're using) gives you at least 25 metres from the firing point to where people are standing. Plenty of larger gardens, allotments, paddocks and fields meet this requirement. If you're not sure, measure it — 25 metres is further than most people think.

If your garden is too small for F3 but you still want a proper show, there's a lot you can do with F2 fireworks. A well-planned display using F2 cakes, fountains and Roman candles can look brilliant. It's about variety and pacing, not raw size.

Do F3 Fireworks Sound Louder Than F2?

Often, but not always. F3 fireworks tend to have larger charges and bigger aerial breaks, which usually means more noise. But the category itself doesn't measure sound — it measures safety distance.

Some F2 cakes with 1.3G classification are surprisingly loud. And some F3 pieces are relatively quiet, producing colour and visual effects without heavy bangs. If noise is your main concern, check individual product descriptions for noise ratings rather than relying on the F2/F3 label alone. Our low-noise collection gathers the quietest options across both categories.

How to Check a Firework's Category

Every firework sold in the UK must display its category on the label. Look for "F2" or "F3" printed on the product packaging, usually near the safety instructions and CE/UKCA marking. On our website, each product page lists the category and safety distance in the specifications.

If you're buying a selection box or complete display kit, check the individual items inside — a box might contain a mix of F2 and F3 pieces. The box itself will usually state the highest category item included.
