For now, most of the 1-MW chargers are located in China, where they have been installed during the last half of year or so.

Therefore there is no wonder that none could be found in UK.

Because BYD and other companies have announced plans to sell such cars in the EU, I assume that they will also promote the installation of such chargers wherever they export their cars.

But I would expect that some years will pass until such chargers could become available everywhere.
