what was this show called??

An old kids show that I think was on CITV originally but was later repeated on the childrens channel. Had Frankie Howard as a rich uncle to 2 familys (one from the south of england one from the north) and in order to win the millions both familes had to swap lives

Anyone out there remember what it was called???

It wasn't "All Change" by any chance?

Oh God, I feel a surge of 'what was that show called?' kind of threads coming on!

All Change brilliant thanks

Couple of other shows i used to watch on the childrens channel years ago I can't remember the names i'll be back discribing in the near future
