Thanks Guys - much appreciated. OH has just pointed out I need to do the bank accounts as well.. don't know why, as there's only a few quid in them and just use them for the occasional ordering of b.day presents for friends and relatives in the UK, but I suppose he's right - now i have to request paperwork from them as aparently they don'y send it automatically, which will no doubt take for ever - might have to stick this one on the back burner after all.
*actually, the idea of telephoning the UK inland revenue with a screaming baby is strangely appealing.. payback time!
