I believe that is Boddingtons yeast, I don't think there will be much of a sub.
1099 - Whitbread Ale
1968 - London ESB Ale
1275 - Thames Valley Ale
1318 - London Ale III
1335 - British Ale II
1469 - West Yorkshire Ale
That list is direct from wyeast web site under their style guide.
There is no direct substitue but this cahrt may be helpful in the future.
