As it happens I've got a copy of the Collins
Complete British Wildlife. The identifications in it are correct. If you look immediately to the left of the spiders name and description you'll see indicators showing which picture it refers to.
Page 198, 1 up from bottom left is the Purse Web spider.
Page 198, 1 up from bottom right is Amaurobius similis.
Your spider is neither of these, and Collins only picture of a Tegenaria species is not much help as its a head on shot, bottom left of page 200!
Hope this helps, but Collins ID's are correct.
No.9 Spider
