you'll be fine , as long as you got your family with you (wife and kids)...might be a little difficult to start with getting jobs but if theres a will , theres a way
I've been here for nearly three years now and i can say I've well adopted the British culture but not the weather...
I can also say that the cost of living near the Black country is also slightly less than if you plan to live near London.
good luck with your plans.
