Seven weeks.
Breakdown:
Company: UPakWeShip
Goods: 28 boxes coming within the size of 100 cubic feet.
From and to: Austin TX to Essex/London border region, "warehouse to door" selection of drop-off/delievery.
Time of year (can affect things as there are busier periods) July
Promised/estimated window of time: 6 to 8 weeks in "peak " shipping time of July, their busiest apparently, so I was warned it might be the higher end rather than the 6.
Arrival time in the UK: 7 weeks.
In my case, I did not ship or bring any domestic items such as mops and brooms, small appliances, or furniture such as couches, beds, TVs etc.
Mainly because most of mine were aging/not worth doing anything with but replacing anyway/ or were cheaply and easily replaceable once in the UK.
