Your hair type (porous, non porous/ fine, coarse, medium textured) will help determine what kind of products to use. It's hard for people to recommend stuff because it might weigh your hair down or not be conditioning enough for your tresses. Can you provide some more information? The NaturallyCurly shop classifies hair products by curl type, so that might be a good place to start.
Also, have a look at the links in the newbie section. There are some awesome resources about how to start caring for your curls all over this forum. Some people have even posted links to videos. It takes some experimenting to find out what works best for your hair but once you've got a routine down pat you might start to really love your curls.
I personally really like curl keeper (a runny gel you apply to sopping wet hair after you get out of the shower), but I don't know if it's available in the UK. Maybe someone else will pop in with some UK product recommendations.
There is a book called "Curly Girl" that some find useful also.
Good luck and welcome to the forum!
P.S. I did a review of a product called "Curl Formers" on my blog a while ago:
They are a useful option to help shape your curls when you're going through a bad hair period. I experimented with them on my blog trying to create a looser curl patter in my hair. Check out the link if you think this might help you out.
