Yes, only retailers, "UK Boarder Agency" (sic) or Hampshire Dibble should have access to UKARA. One-or-some retailers will check for you if you ask, for reasons that continue to escape me.
However, UKARA is just one way of adducing just one defence. Demonstrating any sort of history of having played, and intending to play, airsoft, would satisfy me.
In my opinion UKARA or something similar should be broadened, to not only protect retailers but players, second hand sales and the sport? Seeing more and more news articles about numpties in public waving replicas around.
@Chopper92 While that sounds like a good idea, it could bring GDPR into question. That many people with access to personally-identifiable information would need to be managed very closely.
If we go by the VCRA itself, you really just need "sufficient evidence of that matter is adduced to raise an issue with respect to it" meaning enough evidence that can reasonably show that the guy a. actually attended airsoft events and b. at an insured site. (And c. there is no evidence he is going to use it for something illegal)
a. can be proven by anything like photos or receipts or journey records or confirmation by the site etc.
b. can be automatically proven if the site appears on the UKARA list because only properly insured sites can join their register.
So really you don't need the UKARA per se, but you do need to save a file of how you have checked for a. and b. (and c.)
I know this is not answering your question but just to point out UKARA is not the only method of checking, any method is fine as long as it ticks the above boxes.
