Both of us, depending on who notices it needs doing.
We don't really have set jobs tbh. The only thing I hate doing is emptying the washing machine and hanging it up (our machine is in a little shed thing at the bottom of the garden, away from the house, makes it hard with DCs need to be watched) so I did barter for DH doing all the laundry stuff and I do all the house hold hoovering (he has a bad back, so fair trade).
That's about it really.
Things evened out a LOT when we both went back to work - it had to!
