The importance of the list when moving house can never be overestimated. You need to plan carefully and then follow that plan so you should have lists that show you what needs to be packed and when, the type of labelling system that you are using and you should also make sure that these lists are put together as far in advance as possible so you can get started when you need to. Starting late means that you are playing catch up all the time. Your moving company may be able to offer advice on getting your lists organized.
Clean and dust your possessions as they go into the boxes. This may sound like it will add extra time to the process but it should actually save you a lot of time when you are unpacking at the other end. You do not really want to spend too much time cleaning things in your new home.
If you are packing cables, wires and plugs separately you need to make sure that you have labelled them. It is so easy to forget which one goes with which appliance and labelling them before packing means that they can be easily set up again at the other end. This means that if you want the TV on within a couple of hours of arriving at the new house, it will not take you several hours to find what you need.
