Also I'm a little in the dark as to what certification I would need. I think I need an EPP licence but what else would I need. I don't mind jumping through a few hoops if it will mean I can do all this legit.
Thankyou for any advice, Neil.
You need an EPP licence if you want to possess any of the regulated chemicals, so ideally you'd have one or it limits your options to BP based stuff really.
You need an A&K for BP, ideally. To keep it you need a 'box'
You need an Acquire only for other pyrotechnic compositions.
You should follow the best practice guidance offered by the UKPS, or be able to justify why you didn't if it goes wrong.
But don't get too excited.
You aren't supposed to make anything because you enjoy it and it's fun, It has to be for research, demonstration or experimentation, there is overlap there I suppose, but it would be nice not to have to pretend..
You aren't supposed to store completed pyrotechnics. It's open to interpretation if an item is being stored, or is in the 'drying' stage of manufacture. You could try and get 1.1 storage I suppose
You aren't supposed to transport what you've made, so technically you can't take it 200M down the highway to the farm where you have permission to use fireworks.
100g is for the pyrotechnic composition, not card, hulls etc. My personal interpretation is that it would be legal to make a say, 99g NEC shell, and lift it with a seperate, unattached lift charge, but others may disagree.
As for rockets, great fun but they have to come down somewhere.
Probably best to get all the legal certs sorted and then keep your head down.
But that makes for a dull forum.
