You talking London? I reckon it doesn't snow enough for you to worry as much about grip as winter punctures. A pair of large Marathon Plus should cover you nicely. You'll roll through winter with no flats and when it gets a bit icy they do ok.
That said I'm fairly sure there are actually winter bike threads on here if memory serves and loads of folks see it as an opportunity to build something specific with chunky tyres a big feature. Depends what your riding requirements are going to be.
