I have been in the household removals and storage business for almost 30 years.
We have been amazed at the amount of clutter that some customers carry around with them.
As well as doing local moves in West Sussex, We have moved many people to/from UK/ Europe.
In some cases they could reduce the cost of the removals if they where to get rid of a lot of junk prior to moving the money saved on the removal cost would in some cases pay for brand new effects on arrival at the new address
We have also stored effects for customers at our store in Angmering West Sussex for several years, only to be asked to dispose of it,
My advice would be if you have had something stored in your loft/garage for a year or more get rid of it as you are not going to use it. having said this I think will have to take my own advice my garage is full of junk.

Self-storage: The men who got rich selling empty space - BBC
It's amazing that the majority of us store most of our clutter, junk and rubbish in the garage, and leave our most expensive possession after the house, out on the drive in all weather.
Now it seems a lot of us need even more space, hence the explosion in self storage. "Experts say we have six times more "stuff" than the previous generation"
I think we all just need a good clear out. Box it up, put it in the garage, if you haven't looked at it for 6 months, take it down the charity shop 
Now just need to convince the wife...”
