Sorry to reply to my own post but we got two recommendations from friends which were:Fosters
and Better Removals
Both seemed good on meeting but we went with Fosters in the end based on the quote which was the (significantly) cheaper of the two.
Important different however is that Fosters don't have insurance to cover lofts whereas Better Removals do.
We decided to empty the loft ourselves, YMMV.
Having now moved and returned our boxes, we were very pleased with the service we got and how it all went and our happy to recommend Fosters.
My advise for a smoother home move, always pay for the packing service!
