This looks very like Rhagium bifasciatum, see http://en.wikipedia.org/wiki/Rhagium_bifasciatum which is "one of the most common longhorn beetles in Europe" (though not often in homes probably!) & "
can be distinguished by the two prominent pale yellow bands on each of the elytra" (ie wingcases). http://www.naturespot.org.uk/taxonomy/term/19365 shows (presumably most) UK longhorn beetles, so it's my guess no others have this marking.
(& agree with Quagga on the other eg http://www.naturespot.org.uk/species/wasp-beetle
This is Rhagium bifaciatum one of our longhorn beetles - the larvae feed within the wood of trees and this species has a preference for pines.
Now what's it doing in the house?
Do you have any logs in there?
