We just a a proper bell transformer in the electricity cupboard.

I did have one once, took it out for some reason (maybe it went wrong)
and went battery.

It
lights the bell-push up as well so visitors are more likely to see it.

That's the last thing we need, visitors. ;-)

My wife can be a bit anti-social at time though, so she often doesn't
answer at all while I am out at work!

I'm with her ... unless it's a delivery of course. ;-)
