Why not try it on a handful of popular pages first, and keep an eye open for the bot-browse. Please report back on results, because this Q has arisen more than once (as hinted by JKMitchell's response in msg11), and it would be very useful indeed to get your feedback (both generally, and for myself personally). If you use the META HTTP-EQUIV, please double-check the server response using the Header tool (not all web-servers are setup the same).
If it does work, the next Q will be why on earth your pages are missing from G.co.uk in the first place? Still, one step at a time.
