Necessary Documents for SET(M) for my wife

[Vakella]

Hi,

I have got my British Citizenship in Dec 2012, however my wife is on Spouse Visa from Oct-2011 which is due to expire shortly. Though my wife and I are living at the same address from Jan 2007, for her to apply for ILR next month, we don't have any documents addressed to us jointly, since all utility bills, council tax, TV licensing documents are on my name only. My wife can show only her personal bank statements, and she requested he bank for the statements that cover the last 24 months.
Please can someone suggest if this is ok or anything else that we can do to prove that we live at the same address?

Thanks in advance,
VA
