We moved into a similar house and garden 3 years ago - more ivy than garden! Now is the best time to remove the ivy - nests aren't used at this time of year - they may be used as roosts by wrens in very cold weather so you could get some roosting pockets http://shopping.rspb.org.uk/birds-wildlife/nestboxes/roosting-pockets-x3.html to replace them.
Birds start nesting from early February onwards and it is illegal to disturb nesting birds, so that would be the worst time to do any work on the ivy.
And when removing the ivy please remember that it is a very valuable wildlife resource, providing shelter for many birds, animals and insects. The flowers provide invaluable nectar for bees and other pollinating insects at a time of year when nectar is scarce, and the berries are needed by blackbirds, fieldfares, redwings, waxwings and other birds in the winter when there's nothing else about. So if you can leave some ivy somewhere to grow where it can't do any damage that'll be really great
