There are some schemes, nothing quite as advanced as Y combinator.
- Seedcamp <a href="http://seedcamp.com/" rel="nofollow">http://seedcamp.com/</a>
- Launch48 Launchpad <a href="http://www.launch48.com/launchpad/" rel="nofollow">http://www.launch48.com/launchpad/</a><p>But there are lots of places one could hang out and work on an idea:
- Accelerator London: <a href="http://www.accelerator-london.com/" rel="nofollow">http://www.accelerator-london.com/</a>
- London Hackspace: <a href="http://london.hackspace.org.uk" rel="nofollow">http://london.hackspace.org.uk</a><p>Shameless self-promotion, have a look around here about London based startup resources / opportunities (look at the schmoozing list!)

Another place to "hang out and work on an idea" is <a href="http://techhub.com" rel="nofollow">http://techhub.com</a> @TechHub, a little like a KickLabs but without a fund. But Y-Com 'equivalents' would be Seedcamp (takes 8-10% of a startup) or The Difference Engine programme which is moving to Cambridge (just outside London)
I don't know of a YC-clone in London. There's Seedcamp and <a href="http://thedifferenceengine.eu" rel="nofollow">http://thedifferenceengine.eu</a> up north.
