For me:
- Set up your visa(s) for you and your family or do you take care of that yourself?
Sort of- they did mine from the WP aspect, but I had to do the actual entry clearance visa myself. They were surprised I needed to actually even get a visa, they thought the WP was enough

- Pay for your entire move (furniture, etc) out there?
Sort of- I had a fund of money until it ran out and it didn't cover all of it. But my company is used to moving people within the UK and not from overseas and they only gave me a tiny bit more than what someone relocating within country would get
- Put you up in temp housing for a certain amount of time (how long?) so that you can find a flat?
Yes. I had a nice relocation assistant to who helped me find a place to live
- Provide a housing stipend?
No
- Help you setup a bank/CC/utility account or are you on your own?
Yes, my lovely relocation assistant again helped me on that for bank. Credit card, utilities, etc were all on my own.
I'd be absolutely amazed if your company paid you the same in £ as they would in $!!! If so, what company is that! I want that!
