spiders and skin

Am I right in saying that most spiders (certainly the ones in the UK) don’t have the ability to pierce the skin of a human ?

My colleague says that spiders can and do bite people in this country, it’s just the venom doesn’t effect us much.

I’m sure there was a staff report that had info like this in it, but dammed if I can find it now.

If anyone could point me toward it, or confirm my theory I’d appreciate it.

Cite. Looks like you’re both right.
