If I start an ebay shop, would I have to pay VAT or any other charges (other than the �14.99 a month)?

I'm selling a few items but the listing fees are very high. Will starting an ebay shop lower my listing fees for auctions with reserves on (each item is costing me between �10-�20) and will it lower the final value fee on a buy it now (the fee I'm charged when I sell an item on a buy it now). Are there any other fees (except the �14.99 a month) and will I have to pay VAT on all my items? Is it worth me starting an ebay shop or to sell on my normal ebay account?
