Re Paul Cobb possible Raft Spider.
Not that one Paul. You will be surprised by how big they are when you see a Raft Spider!.
It looks like a Pardosa wolf spider.

NB you can never be sure of an spider ID until you have used a microscope to check the tiny details (must not use that as a euphemism in future! Could get into trouble)
