After looking around I used the Bronze package from Companies Made Simple. It ended up being slightly cheaper then using Companies House direct (my understanding of which is that Companies House only charges formation agents £14 per company). Both give you a PDF of the Certificate of Incorporation which you can print off yourself for the bank if they ask for it, plus if you're happy with Barclays the £50 cash back was pretty sweet.

I also used Companies Made Simple. Everything was fine with them, except that if you have non-ASCII characters in your name they will look scrambled in some of the official documents. Use an ASCII transliteration for your name instead of using non-ASCII characters.
