OK, just like anything else, everyone has their favorites (like w/combustible cigs, some like Marlboro, others will say that sucks, Camel's better), so let us not get into this "fanboy" this and that kind of argument here, and focus on helping the newbie.
Seeing as you are in the UK, I would suggest getting three more posts in here (so you have five), and then you'll have access to more sub-forums. In particular, you should visit the UK Forum
HERE. They can help you find a vendor good for you in the UK, and avoid International shipping, etc. There may even be a physical store near you to which they could refer you.
Something to consider before looking at the choices is whether you think you must have a "cig-a-like" (cigarette-sized), or you would be willing to deal with one a little larger (say, cigar-sized), in order to improve battery performance. The former do not last long between charging, while the latter (depending on size) lasts much longer. So consider that first. Also, there are different attachments to the top of the battery that hold the liquid that heats into vapor. Again, everyone has their preferences, and many will insist their preference is best. The reason there are so many choices is that different equipment works better for each individual. To start, I would recommend getting a box of cartomizers (typically in a box of five) and two or three clearomizers (such as the "Stardust" aka CE4+, or the T2, if your battery has a "510" thread).
Finally, e-liquid. You can start with a tobacco or menthol, many, if not most, of us did. But keep in mind, the tobacco flavors are more like the smell of an un-lit combustible cigarette, as it's near-impossible to capture the flavor of burning leaves and paper.

Many people still use a tobacco or menthol flavor, and I do on occasion as well. It just depends on my mood. Some still use one as their "ADV" or all day vape (flavor). But many have also turned to the fruity or dessert flavors, of which I love several as well.

So with your hardware kit and clearos or cartos, be sure to get some e-liquid in a couple of smaller sizes so you don't waste something you end up not liking.
Let us know if you have any more questions, and remember to visit the UK forums after three more legit posts!
