IGNORE the above post - do not use a local player for this type of move. Just imagine who might turn up in London on the day of your move!!
I have used three international
Movers since my life as an expat began:
First, if money is no object, go with Abels (they are by Royal Appointment and handle all of the Queen's gifts she receives from foreign dignitaries). They packed every item carefully, labelled and generally did a fantastic job. There were, however, not cheap at all. That is the price you pay. I think we had one broken mug and that was it.
Second, we used Allied Pickfords (or which ever one it is these days: Team Allied or Pickfords). For our move from Dubai to Singapore they did an adequate job but there were a few breakages and scuffs/dents on our bed and tables etc.. They were in general terms pretty good.
The third option is to go local - I have used local shippers in Dubai and Singapore and on each occasion have been horrified by the service and quality of the packing. In particular, Singapore
Movers seem to be groups of young students more interested in messing about than getting the job done. Avoid is my advice. They are of course, the cheapest option.
Good luck!
