So I agree with Chris, it's a Great Crested Grebe, on the verge of adulthood.
I was going through some old photos and came across it, I thought it was a Grebe but after trying to confirm identify it in my bird guide, thought it best to put it here. Thanks very much guys
The presence of the brown feathering on the lower rear cheeks and the suggestion of a crest both point to an adult at the end of the summer...a young bird would not have those features yet.
