There's some effort going on in Croydon (that's South London, and one of the cheapest parts of London for those of you not in the UK): http://croydontechcity.com/ (heh - just noticed I'm in one of the pics on their site)

They run regular event to try to pull together a startup community, and it's extremely well attended, to the point where they've had to restrict numbers for some of the meetings. It'll be interesting to see what comes out of it - it's only been going for a year or so, but seems to be growing rapidly and it does seem like there's an increasing number of actual startups rather than just people talking about it.

Croydon, despite its reputation has the advantage of lots of cheap low grade office space (though the cheapest stuff in the main business district is gradually being demolished to create space for new high grade expensive high rises, but there are also a couple of "retail parks" in the midst of a sea of cheap office buildings and warehouses a few minutes walk/bus out of the town centre), there's at least one local data centre from a good provider, and it's very well connected to central London and the South coast.
