to s&l you have nothing to worry as based on my experience, we submit the following:

2 original phone bills on both our names
2 original bank statements on both our names
bank statements on my name
bank statements on my hubbys name
my medical card
jobcentre letter for my NI number
my husbands pension letter

i submitted more than 6 and the officer just pick the best to photocopy and got my visa

to jane just ask the company if they can post you the bill for ur record.

goodluck to all
