Hi
we returned late last year. I did a lot of research. these were my findings.
Many shipping companies wanted to get their workforce to pack the box and they would only use NEW ones.
We had many of our own original boxes form movie in the first instance so were happy to reuse if we could.
I used Trans international.
We decided NOT to take any furniture home, we sold EVERTHING on FB pages and in the end had 32 boxes coming to 5 cubic meters. Cost us $1500 and because i was able to pack myself, NOTHING was broken when it arrived in the UK and all boxes were FULL!(when we arrived in OZ we were amazed how much free space were in some of the boxes packed by the UK shipping company.
When we arrived back in the UK the UK side were amazing with detail and communication. I would, with out fail recommend trans international.
