I have to say I'm very excited for the lucky recipient of all this! Photography is a wonderful hobby to have, I really can't put into words how much enjoyment my camera has given me and how many amazing memories I've captured with it.

For £700 that is your best bet in my opinon. The 600D is a great camera, it's got everything a new photographer needs. The lens bundled is a jack of all trades and perfect for a rookie photographer to find their niche: zoomed all the way out, it's good for shooting landscapes, the middle is great for portraits, and zoomed all the way in will be just about enough for nature and sports photography. As a bonus, the 600D also shoots HD video, which combined with that lens will give you incredibly high quality video. You will also need to buy a memory card to store all the pictures on. A standard 4GB SD card will do the job fine.
I would also recommend you buy a UV filter to screw on the end of the lens. For this camera's lens you need a 67mm filter. The filter will act as a barrier between your precious new lens and all the nasty sharp things in the world.
I cannot emphasis how important this is. If you scratch you UV filter, it's not expensive to replace, and your lens is still in in perfect condition. If you don't protect your lens with a filter, any scratches you pick up are permanent, and could potentially ruin the lens.
If you have it in your budget, these are some optional extras:
You might also want to get a cheap (~£50) tripod. This will help keep the camera still, and therefore give crisper images. You can also use it for self timer shots.
A good quality camera bag is nice to have. It will give your camera a bit of protection and give you space to keep all your accessories close to hand.
