Looks like i may need to go via a swap DEX site where ill loose a bit on fees unless there`s another simple option?
There are a few P2P platforms that allow you to buy cryptocurrencies directly from other users. Have you considered the options of using some of them, like for example Bisq to buy Bitcoin? Once you have some form of cryptocurrency, you will have more options to find a platform to exchange to any other altcoin you want. As far as I know, DEXs are not regulated by the FCA, so you may have more options available.
