IF this product is intended to be connected to the mains electricity, you would need an EU to UK plug adapter (2 to 3 pin).
First of all, if you spend £ 400 in products (at least), we'll send the EU to UK plug adapter for FREE!
If you prefer, you can buy a similar product at your local store or somewhere else, instead.
OR (at your risk): Anyway, nowadays almost any electronic device is unearthed and doubleinsulated, because they have a smart internal protection. So, you could push the earth hole on your wall power outlet or multi socket extension bar, with a long piece of plastic or wood (never use metal!) or by another upset power plug, in order to insert the EU plug into the outlet or multi socket.
