I'm gonna throw my two cents in here and say get a kit lens. With your first DSLR, it's important to get a kit. You get to learn a lot about different focal lengths and you get the freedom to decide which one you want without having to spend a wallet full of cash on lenses. Canon kit lenses aren't too shabby and rarely have issues with animation (see: ForlornCreature), though the general style of the lens isn't as "fancy" since the optics are pretty standard (aka, you don't get swirly bokeh or cool lens flares because it's a factory-made modern plastic lens).
I for one enjoy having my kit lens even though I have 105mm, 58mm, and 28mm lenses. No, I don't use my kit for animating very often, but if you don't have the freedom of a wide range of focal lengths, you'll be seriously limited without your kit lens. A bunch of my films only used the 58mm, and while it isn't that obvious at first, all the shots look distant because of the long focal length.
Sometimes you just want that freedom to have a dramatic zoom-in (see: MECH) or to have a different focal length. If you can get a kit lens for only £20 extra, go for it. It's worth it. I mean, a DSLR is an investment anyway, so you if you can get an accessory for relatively inexpensively, you should.
