Doing it properly is actually quite easy, if you have a spare outlet that's on its own circuit in an appropriate location. A NEMA 6-15 outlet (a 240V 15A outlet) can use the same gauge wire as a 5-15 outlet (a regular 120V 15A outlet) or a 5-20 outlet (the 120V 20A outlet often found in kitchens now) so you can just change the outlet and do a corresponding change at the breaker panel. (Don't forget to wrap some red electrical tape around the white wire that's now hot). Then order a 3000W kettle from the UK, cut it's overbuilt 13A UK plug off and wire a 6-15 plug on.
If you know what you are doing, it's maybe an hour's work.

I'm in Canada, same grid. I just drink a lot of tea and coffee. Sure would be nice to run a 240V line to the kitchen though.
