DynAero
I've since discovered that they have relocated to Pau in the Pyrenees and have a good and informative website. However, their head of sales Francois Catuhe tells me that while the LAA accept the type they do not currently have a UK distributor (although they're looking for one); and that although they can provide a factory-built aircraft on the F register, for the G-register it has to be home built. I'd be perfectly happy with one on the F-register, as that is where I will do most of my flying, but if I read the regs right, outside the UK my UK-issued EASA PPL only allows me to fly EASA aircraft, if they're not on the G-reg, and I guess the DynAero VLA is never going to be an EASA aircraft.
None of this seems to make any sense to me, but then light aircraft regulation never does.
