My husband was able to get transferred with his company, but since it was a voluntary transfer they really didn't help much with the costs. He is in IT, (web middle-ware engineer --whatever that is. I'm a nurse and was able to interview over the phone with BUPA and secure a job.
If you can stay with someone, that will help a lot with expenses, by not having to pay for a hotel room and by saving on meals. We just went to several estate agents.
Also, since your husband has ties in the UK already, he might want to see if he can set up some sort of bank account before you move.
Also, I'm not sure what/how your visa works, when you will be able to work, etc. My husband has an Irish passport, so I was able to work right away without visa issues, due to EU rules.
Although we have liked living here, we are looking forward to going home.
One word of advice, it is expensive here- we live in Kent and it is still expensive (we're about 35 miles southeast of London)-- if it costs a dollar in the states, it will cost a pound here is the rule I sorta go by.
Salaries do not double here (even though the pound is strong). Say if you make 40,000 USD you probably will make about 20-25,000 pounds, at least that's been our experience. And everything does cost more here. Like the 10 dollar bucket of chicken at KFC, costs 10 pounds here. So you do have to adjust your living standards, I think. A meal at McDonalds would be 5 pounds here, vs. 5 dollars in the states.
Anyway, good luck! Having family here will help loads (we didn't know anyone)
