Observer reports that upon unpacking a delivery of new furniture, this beetle was discovered.
No interactions present.
Interesting beast - do you know where the furniture came from? It looks like a member of the genus Semanotus which doesn't occur in Britain, but I can't be sure (and definitely not which one, though it looks close to S. laurasi) - plus I guess it could be an odd colour form of something more familar. If this turns out to be genuinely unusual, I imagine the longhorn recording scheme might be interested: Dr Martin Rejzek, http://www.brc.ac.uk/scheme_details.asp?schemeChoice=7
It's not one I've seen before, and Dave's suggestion looks like a good one. Will see if we can get it checked.
P.S. to Dave: I've edited your comment to remove the email address, it's best not to give out addresses in the iSpot comments.

The closest species I could think of was S. laurasi but the pattern's not quite right and I don't know if it is variable. PS about emails noted,
