but I'm not allowed to store Cat 4 items unless I have the correct storage lisences and insurance, which costs a small fortune.
Not as expensive (or as difficult) as one might think at first.
MSER Costs for registration and licencesTo register to "Store Explosives" costs:1 year £60 + £30 to renew
2 years £90 + £60 to renew
3 years £120 + £90 to renew
A licence to "Store Explosives" costs:1 year £100 + £75 to renew
2 years £150 + £125 to renew
3 years £200 + £175 to renew
A licence to "Manufacture Explosives by means of on-site mixing" costs:1 year £205 + £115 per hour of inspector time + £73 to renew
The requirement for registration/licence is determined by the amounts you wish to store. The criteria are quite long so I leave you to look up the MSER.
Your storage quota would be determined by what is near your magazine. For Type 4 explosives there is no real problem or us (unless you plan on having over a quarter of a tonne). For type 3 explosives, again not real a problem for us (up to 25kg is not regulated as far as safe distances are concerned). The problem comes with higher order explosives. For type 2 your need 73m between your magazine and any vulnerable building, for type 1 its bloody complicated. As a ROUGH guide, most compositions would be a "hazard type 4 explosive" where as a manufactured device (shell) would be a "hazard type 3 explosive", obviously 500g of flash would be a type 2 or even 1. A larger shell/rocket would be up to about 2 and maybe type 1 if large enough and a sufficient amount were in storage.
I used to paddle for GB, a bit more than a hobby in terms of time I know, but I used to spend well in excess of £2k a year on memberships, insurance, racking fees, boats, paddles and other kit. So compared to this, getting "legal" (turn your shed into an explosives factory
) is relatively inexpensive, certainly not too expensive for 10 or so in the same area to start a club and have a factory in a field somewhere. The previous thoughts about it costing millions are a little out, actually the figure is in the tens of thousands for initial layout to start a small club, maybe that would rise to near £100k if you were looking in the SE of england.
I think the UKPS is frantically at work producing a guide on exactly what you can and can't do etc. and how to go about getting licensed. So support the cause if your already not a member!
