Basically every European state has at least one national testing lab and even though approvals are recognised throughout the EU, many appliances still carry a whole list of approvals. The TÜV has branches all across Europe so their logo can be found on a lot of stuff, but it's not exactly what I'd look for on electric equipment. There the national electrical approvals such as VDE, IS,... are more interesting. For UK appliances it should be the "Kite mark" I think.
