I'm also British, and found YC invaluable setting up in the US. Kirsty Nathoo, one of the YC team, proved very helpful with her knowledge of both UK and US accounting norms.
Remember that for anyone wanting to apply for funding to Y Combinator that we only invest in US corporations (registered in Delaware), which means that the parent company will need to be a US company. So if you're thinking about applying you probably should hold off on any type of incorporation in the UK, until you know whether you'll be in Mountain View over the summer!
