Compounds

A compound firework is multiple cakes or barrages pre-fused together into a single unit on a board. Lighting one fuse triggers the entire sequence automatically, firing each section in turn to deliver a continuous, varied aerial display. Also known as compound cakes or compound barrages, they can contain 100 to 400 or more shots and typically run for one to four minutes, with some lasting nearly 7 minutes, making them one of the most impressive single fireworks available to consumers.

A standard cake or barrage fires a sequence of shots from a single set of tubes. In Category F2, these are typically limited to 500g of explosive content (NEC), and up to 1kg in Category F3. A compound firework combines multiple cakes into a one pre-fused unit, allowing for a much higher total NEC - up to 2kg in Category F2 and up to 4kg in Category F3. This increased capacity means compounds can produce larger bursts, run for longer, and deliver a wider variety of effects compared to a single cake.

In simple terms, a standard cake delivers one continuous sequence from a single unit, while a compound links multiple cakes together into a longer, more powerful display - all from a single ignition. They’re the natural choice if you want a bigger, more impactful show without needing to light multiple fireworks.

Compound fireworks come in different categories depending on the space you have available. Larger compounds are typically Category F3 and need around 25 metres of clear distance, making them best suited to open areas like fields or larger gardens. Smaller options are available in Category F2, which require either, 8, 15 or 20 metres and are better suited to more compact spaces.

The easiest way to choose is to match the firework to your setting, smaller space - go for F2; more room - F3 gives you a bigger display.

Always check the safety distance on each product before buying to make sure it's right for your setup.

This is completely normal. Short pauses happen as the internal fuse transfers from one linked cake to the next, allowing the display to continue in stages. It doesn’t mean the firework has stopped or failed. Never approach the compound firework during a pause. Always wait until the display has fully finished and the firework has completely cooled before going near it. If no further effects occur after several minutes, treat it as a misfire and follow the safety instructions provided.

Compound fireworks are a popular choice for finales, but the key to a great ending is pace, intensity, and variety, not just size. A strong finale should feel fast, dynamic, and packed with effects to create a real “wow” moment.

Both compound fireworks and a combination of cakes, barrages and rockets can achieve this. Compounds offer a convenient all-in-one option, delivering a continuous sequence from a single ignition. Alternatively, firing multiple cakes or barrages in quick succession alongside a few well-timed rockets, can create a faster-paced, more explosive finish.

The best approach depends on your setup. If you want simplicity, a compound firework makes an easy, reliable finale. If you’re looking for maximum impact and control, combining different fireworks can create a more intense, high-energy ending.
