Thanks for posting the above :-)

In this area of the country, English ivy should be avoided. And to add to this caution, the ivy in your first photo has developed to the adult stage - it is setting flower buds which will bloom and be followed by berries/seeds that are eaten by birds and then dispersed all over the countryside, furthering the invasive issue.

If you must keep the ivy in place, shear it back now to get rid of any adult foliage (non-lobed or heart shaped leaves compared to the pointy lobes of the juvenile form) and the flowers/berries the adult form will produce. That will at least curb some of the problem.

If you need more privacy, replace the vine on the fence with an evergreen shrub. There are dozens that could work.
