Hate Ivy. Hate hate hate. Our next door neighbour (the one that's a bit of a nutter) has it growing on his wall and over the garden wall, I'm forever chopping it back, trying to leave only 6 inches or so hanging over the wall, but we've got blackthorn there, so trying to untangle it is a bit of a nightmare, plus I'm now going to have to leave it until late autumn to give a good going over, as there are several sparrows nesting in the hedge.
I removed it from the back of our house last year using an extendable pole and my wolf patio knife - great for slicing it away from the brickwork. It has left marks though, which I am really annoyed about.
If you like it, for heavens' sake plant the dratted thing in a pot, otherwise it will rampage all over your garden, putting down roots wherever it hits soil. It's a flipping nuisance in my garden, will be glad when we leave and I don't need to do battle with that any more.
