I used Allied in the States for the same reason -- they were associated with a small moving firm local to my destination. I had no problems with the packing up job Stateside, but my UK movers said they did a crap job wrapping my stuff. In any event, nothing was damaged.
I had been quoted in dollars and expected to pay in dollars, but they actually insisted on pounds and I had to pull some money over quick. On the other hand, I totted up what had happened with the exchange rate since the quote, and I was better off paying in pounds, so I didn't kick up a fuss.
The total for three quarters of a container was £4,800. That included pick-up, delivery and a bit of storage time at both ends. That was January of this year. Hope that helps.
