[Trehopr1]

This is a species of "Rove beetle" of the family Staphylinidae. These are harmless and they're actually predators in their world. This is not some grain pest....

Despite their shortened wing covers they're flying wings unfold quite nicely from beneath them thus they are very capable flyers. It's springtime and you may have gotten in a couple while a door or window was open for a time or they could have come in under the threshold of an outer door to your home where there is oftentimes a gap.

You might try looking up the term common Rove beetles of Britain on the internet and it may show you some of the most commonly encountered ones. Perhaps this one will look like one of the pictures. Any reference book specifically on the insects of Britain will likely also show a page or so of some examples as well.
