Fireworks Guide: Rockets

One of the most popular - and spectacular - consumer fireworks available in the UK.

Key information

  • Fired from the supplied launch tube into the air (note: never fire rockets from the hand or from bottles).
  • Nearly all rockets bang with their effect.
  • By far the highest consumer firework effect; large rockets can reach 300ft+.
  • But one of the shortest duration fireworks available, usually just a few seconds each.
  • Safety distances typically 8m up to 25m.
  • Sold singly or in packs.
  • 1.3G rockets usually significantly better than 1.4G rockets.
  • The rocket’s stick can travel some distance and will return to earth – ensure you have a suitable fall out area.

The anatomy of a typical rocket


Main body: The effect is contained in this part of the rocket and explodes out of this when the rocket is in the air.

Motor: The part which gives the rocket its thrust to take off.

Fuse cover: Always remove this prior to lighting the fuse underneath.

Stick: This is inserted into the supplied launch tube. This part and sometimes some of the casing comes back down to earth after firing.

Warning label and instructions: The important things you need to know about firing the rocket, its classification (Category F2 or F3), safety distance and so on. It is on the reverse of the rocket shown.

What type of effects to expect

Rockets are a one-shot firework; they take off, explode with an effect and that’s it, usually in just a second or two. However they can be one of the most spectacular consumer fireworks with the larger effects creating a brief but massive, sky-filling display. In fact the very largest consumer rockets can reach 300ft or more, significantly higher than even big bore cakes and candles.

But be warned that smaller rockets (especially Category F2 1.4G) can be quite tame in comparison with just a “pop” and weak effect, see below for more guidance on this. The smaller rockets typically fly to less than 100ft and their effect can feel a little lost.

Effect types in all sizes of rockets include hanging gold willow, coloured stars, crackles and more. Rockets that simply bang loudly (known as a salute, maroon or signal rocket) have fallen out of favour and are currently hard to find.

A larger Category F3 rocket is shown in the video below (costing £25 to £30):

How much do they cost?

Rockets are sold either in packs, or singly.

Rocket packs can retail for as low as £5 or so and go up in price from there. Single rockets typically cost £20 or so each but are significantly bigger than those found in packs. As an example, a bigger Category F3 rocket might have an overall net explosive content (NEC) of 180g but a rocket from a smaller Category F2 pack only around 15g or so.

It is not economically viable to produce, pack and store small rockets and to sell them individually, this is why single rockets tend to be much larger and more expensive.

Your retailer should provide you with a tube to fire single rockets from and most packs already include one.

1.3G vs. 1.4G rockets

Like all consumer fireworks, rockets are given a classification of 1.4G or 1.3G. This classification makes a big difference to the power of the rocket.

The less hazardous classification of 1.4G is easier to transport and store (hence being liked by retailers and seasonal sellers) but with rockets can produce effects lacking in much of a bang or big effect. 1.4G rockets typically create more of a “pop” with a small ejection of glitter. They’re great for back garden displays or if you want to keep the noise down.

However 1.3G rockets although less widely available unless you shop at a specialist, are allowed to contain more explosive power which is required to create the big spread of effects and a reasonable bang.

To complicate matters, some of the larger rockets are 1.3G but are supplied in special packaging known as pyromesh which allows them to be classified as 1.4G.  This allows retailers to both store them and send them via courier in the case of mail order customers.

So for the best effects in rockets look for either 1.3G rockets or rockets which are 1.4G because they are in pyromesh.

Firework retailers usually make it very clear if a rocket is 1.3G or pyromeshed. You will also have their video clips to watch to check out the quality and power of each rocket.

Be aware that having the more hazardous 1.3G classification of firework in your display may have implications on how many fireworks you can store and how long for.

You can read more about these subjects in the following guides: Firework Categories & Classifications, 1.3G or 1.4G Fireworks?That Pesky Pyromesh, and Safe Fireworks Storage.

The 1.3G or 1.4G classification should not be confused with the rocket’s category of F2 or F3 which is separate and will dictate the required safety distance. 

Category F3 rocket height
Photos of consumer rockets with people to scale are rare but this one from my archive demonstrates the height larger F3 rockets can reach. Aside from the oak tree for scale, there are three firers shown sitting by the base of the tubes. Using these for scale I estimate that the lowest rocket is reaching about 300ft high, with the others even higher, off the frame.
