I've let ivy grow up the back of the house, as it looks quite
picturesque. However, now it's reached first floor level and is growing
over the window panes, I'm beginning to have second thoughts as to the
advisability of letting it rampage.
Any advice?
If it's not destroying any brickwork or undermining the mortar it's
your call, but regular attending to is essential to prevent it going mad

That's a very informative link.
I had a lot of ivy on my house, and although not as spectacular as the
Street View example, had invaded the roof and the loft. I removed most
of it, and now have only a small patch, which I keep strictly under
control.
I've also got some Virginia Creeper, which although equally invasive, is
easily pulled away from the wall.
As
http://www.whatprice.co.uk/gardening/ivy.html also says, ivy can
seriously damage trees. There was massive (60'?) ash tree just outside
the end of my back garden, with quite a lot of ivy growing up it. I
suddenly noticed that its leaves were beginning to shrivel, while those
on an adjacent, mainly ivy-free ash were OK. On investigation, I found
that the ivy stems had got under the bark, and lifted it around the
whole of the circumference of the trunk, effectively ring-barking it.
Since then, I have made sure that the same fate does not befall its now
solitary neighbour.
