Well done!
I'm paid monthly on 25th, in 2016 my pension contributions arrived the following month on 8, 8, 7, 7, 9, 13, 7, 9, 19, 7, 12th of the month for January to November (salary paid early in December so I'll ignore that). Which I think is pretty poor really, I don't see why it should take more than about three working days for the money to arrive and be invested. I can't really imagine anybody in my company's HR department giving a stuff about it though (if they even understand what I'm asking)!
