If they are already outdoor cats can do you have a cat flap? If so you could leave it open for them to come and go as they please.

If you are at work all day and the cats are in the house they will probably sleep which is why they are wide awake at night time! LOL

Mine used to do this all the time - in the end I learnt to sleep through it.
Since we have moved house they have access to go outside during the day and then i keep them in at night and then they know its bedtime and go to sleep
