Road bike recommendations

Looking to get a road bike on the cycle to work scheme so have £1000 max to spend. Is carbon out of the question at the price? I'm looking for something that is great for long distance and also looks half decent. Any recommendations would be appreciated as I really know very little about road bikes.

Planet-X usually do something with a SRAM mix for a grand.

But a good alu frame might actually be better at the same price.
