All of the concerns I can think of have already been covered by clephan, cj and lucytalk.
However how will you predict what scents will sell strongly over here though? To keep stocks up, as I understand scents at the moment are made on a 'need to make' basis. I think that to stock the shop initially will be a huge drain on BPAL's resources to give a balanced mix of scents. BPAL is 10-14 days behind at the moment anyway, wouldnt it be better to concentrate on catching up rather than making huge batches of perfume for a foothold in a new continent.

The other problem will be pricing as the shop will have to make a profit too, so the prices in England will increase to cover other costs such as shipping and middle men fees.
But I do work as a web designer in a UK media based company and I've been learning some PR techniques from our guru's in the company. I personally think that the best thing you could do is to find another store in the heart of one of the UK cities who would be willing to sell them. The prime location will offer greater access to people who can get there and there will be more chance from people who dont know your product to sell them. There are plenty of goth markets in the UK and these will be your *ideal* target as the product names will appeal to Goths more than anyone.

However I would think about asking Black Rose about whether they would like to stock BPAL scents first, as they are one of the more established goth online shops on the Internet. But instead of sending them an email, I would send a parcel with your strongest selling scents along with a letter asking if they would consider selling your product online and in their shop (located in Camden Market which is in London; the biggest goth market in the UK!). Make the letter personally tailored to them. As you have some complimentary scents with the letter, they can see what the product is like.
Hmmn, I talk too much.
Interesting possibility though.
