Last time we moved, 6 years ago (both houses in Leeds and approx 10 miles
apart), we had them do the lot. We left our old house in the morning went
to work and returned to our new house at tea time, a neighbour made sure
everything was taken from the old house before the lorry drove off.
Everything was in put away and tidy when we got home. All we had to do was
leave them a list of which room was going to be which room in the new house,
if you see what I mean. My wife also packed her 'smalls' and took them to
work with her. Even the loo rolls were on the holders! Admittedly
everything wasn't in the 'correct' cupboard etc. in the kitchen but it was
far easier to redo these than pack up a whole house! The only things they
wouldn't do was any loft spaces, either empty or refill. They had cardboard
stand up wardrobes and just transferred clothes on hangers into them and
back out at the new house, this would be a problem obviously if the new
place didn't have any wardrobes.
If I remember correctly it cost somewhere around £350-£400 quid, but offset
that against hiring a Transit Luton, fuel, and trying to get 4 or 5 mates on
a Friday to help when they all work, not to mention the crates of ale and
chinese takeaway you would need to furnish them with.
