@Lozzer - when you ask for spider ID's is very useful if you provide:

1: The size (excluding legs) on spiders with large jaws like this, to the front of the body.
2: Location - where you found it in the UK
3: Habitat, and anything you think that could help (egg sacs, web etc)

Anyway - to the spider

Yes looks like a Dysdera crocata, if you look closely on leg IV femur you can just make out 2 spines.
