....so I, too, googled (as you would ;D)....and played about with words, cos the family is so v.v.large....like you, can't come across a definitive on-line reference, tho Collins seem to do books of garden & house spiders in the UK/N.Europe...actually, like my bird books, a nice thing to read and have - a novel(!) change from staring at a screen? But all that's not going to help you, is it?
Not sure how to insert a link. But here goes:http://www.wildaboutbritain.co.uk/gallery/browseimages.php?c=30
Have printed off your last comment. I have a neighbour who works for a local animal ambulance. Will ask him later on this week.
I've been to see the neighbour and he has lent me a book. Also given me a list of latin names to what it could be.First of all, we need to know whether the body is round or elongated?
