Why a fused one? How is the rad currently supplied??
And even after you've got a new element with a longer lead it'll still look pants trailing over the wall like that.
Take the rad off, cut the tile here-ish
(probably further to the left so that the accessory plate lines up with the RH edge when fitted) - that way there'll only be two cuts to make in the tile), and put a polished chrome outlet plate there. It'll be fiddly to get the rad wired in - you'll need to support it as close as possible to its installed position so that you keep the flex as short as possible, but the end result will be worth it. You could move it further down if you wanted to - I'm sure at some point you'd find a position where the flex was long enough to reach, so no new element. You might even be able to get it below the rad and not need to take it off the wall.
Another idea which would avoid cutting the tile, but wouldn't look as good, and might not be appropriate for the location anyway would be a surface mount polished chrome pattress on the wall.
