I'd never even heard of a house centipede, so I googled it. I've never seen one before and I live in the UK. Apparently they occasionally sneak into the UK in imported food packaging, but they're not native or common here.
Nearly all instances go unrecorded, so precise frequency of distribution in England is impossible to determine. But they have spread across the globe to all countries and all continents except Antarctica, so chances are nearly certain you've got them in your home, even in England.[1] They're a little startling, but harmless to humans, and help keep your spider population in check. Even though I have probably only seen 5 of them in the last 20 years in places I have lived spanning the Eastern Seaboard of the US, I have no delusions about they being there regardless of spotting them. Unless they're disoriented and dying, like most "bugs," these things are supremely sneaky.
>> S. coleoptrata is indigenous to the Mediterranean region, but it has spread through much of Europe, Asia, North America and South America.[2]
