Hi JulieAnne,
Thanks for contributing to our forum. I just reviewed the statement you are referring to which says "Only available to Top Rated Sellers" and it appears that is showing up in error, so we are going to work on having that removed with a future site update to prevent any further confusion.
Therefore, you should be able to use any of the options in the Marketing Tools section at this time, even if you are not a Top Rated Seller.
You can learn more about the listing upgrades that are available on eBay UK and the associated fees on the following page of eBay's Help index: http://pages.ebay.co.uk/help/sell/fees.html
I hope this helps!
