Citizenship application

[Sreyas]

"June 2014" AN form states: Please note that each individual applying for naturalisation must complete a
separate application form. Therefore husbands, wives and civil partners
wishing to naturalise, must complete separate forms. [b]For a “joint” application
attracting a single fee,[/b] the applications for a married or civil partnership couple
must be submitted together.

My wife is on ILR since 1 and half years. She completes her 5 years of stay in the UK in June this year. Should I apply for her british citizenship along with me now (i have completed 6 years here) or should I apply for citizenship together in June so that the application attracts a single fee?

Fees are separate now.
