Don't panic, you have time to plan everything down to the last detail, but it is going to be hard work.
Ideally, it would probably be least disruptive if you could move straight into the bungalow when you come. Would the vendors leave white goods/curtains/ wardrobes etc? Or is there someone in uk who could prepare the bungalow for you?
Another thought...Where are you coming from? Could you organise a moving company to bring your things over by road?
Aim for others to do all that kind of stuff, leaving you to fly home with suitcases as if you were going on holiday. You will need to focus on there being as little disruption as possible for your husband.
My mum's dementia was more advanced when I brought her back from Australia, but we packed 3 suitcases with clothes, photos and favourite ornaments etc on the morning of the flight and just came, leaving my sister to sort out her house. Mum was going into a care home and my brother drove us straight there from the airport.
I think you are wise to bring your husband home sooner than later. We should have done it sooner.
