That image is way too tiny... but I think it looks more like a bug (Hemiptera, Heteroptera) than a beetle (Coleoptera). Perhaps you can get further by visiting British Bugs (assuming your front room is in Britain, of course).
Thanks for you help, The Garden next door is some what unkempt and full of nettles, so I guess thats where it came from. It may well have got into the house via my fire wood store. which was close to the nettles.
I have managed to get a better picture, after reading the camera's manual.
