Thank you all for your advice.
Lamb family - very informative response thank you
I should have said in my original post, although we're buying a car, we won't be paying for it out if the £10,000. This will be bought on hp/finance. Also re Medicare, hubby's company are paying for a basic level of cover but we have discussed topping it up ourselves. That's something we will have to look into when we get there.
We will be cramming as much as is possible into our container. The white goods are intergrated, so unfortunately we can't bring them.
The responses on here have made me feel much more confident. Thank you all
