Given your location, it might be a Brittish company in which case I'm utterly clueless.
But just speculating beyond that, if it were German, which would certainly seem possible given the style of the vase, I would think of Nachtmann Riedel. Most of my Nachtmann vases are marked with Nachtmann only, but it could be possible that they used a combined name logo at some point. In which case it would be after 2004, the year when Riedel took over Nachtmann. Unfortunately I haven't seen this sort of logo before, so it remains sheer speculation, sorry.
