Pachygnatha clercki
This was found in a pitfall trap (in propylene glycol, so no live photos). The Britain's Spiders book suggests you need to see the genitalia for certain ID of this genus and I wasn't entirely sure if what I could see of the epigyne clinched it or not, but with a body length of 6.6mm I think it's got to be clercki.
