Hi Tallus, any spider described as having orange legs would usually say
Dysdera species to me, ie; Woodlouse spider, and one of the few British species able to inflict a bite upon humans. Have a google on
Dysdera crocata.
Much of the reaction from spider bites can be caused by secondary infection of the wound from germs around the spiders fangs rather than envenomation - after all you never know what the spiders last meal was walking on

.
Any chance of a better photo, it doesn't come close to helping with i.d. at the moment.
