You can get a Canon 1000D body only for just on £300 from either Warehouse Express or Amazon, or get a 1000D + kit lens for a little over £350. That would leave enough for a 55-200mm to round of the kit as a starter.
Alternatively you can get a Nikon D3000 for around the same price - either body only or body + kit lens.
Depending on your style and preferences, the requirements of the course and so on, a low cost option would be either a 1000D + 50mm f/1.8ii - total cost approx. £370. Or, a 1000D + 35mm f/2 - total cost approx. £512. Having a single prime to work with can make you more involved in composing a shot, get you thinking more about composition and moving more in order to achieve that. For a 35mm lens on a 1000D the cropped field of view is close to that of a 50mm (standard) lens on a 35mm body; while the 50mm FOV is equal to 80mm. The 50mm is also a good, and cheap, starter portrait lens. You could then just borrow zooms, or other primes, from the college as needed.
