Claimig benefits

[Rajapk2012]

Hi members

I have applied benefits in may ,intially they awarded me only child benefit, but housing and Tax credit and child tax credit were in process,

On 26/6/2012 i sent my wife application FLR(M) and i mentioned same in benefits part that i am getting only child benefit,

But on 27/06/2012 i received letter from Tax Credit dept that my application successfull and i will receive £86 per week and on 28/06/2012 they transfered in my account, on 29/06/2012 i received letter from housing benefit dept that i been awarded housing benefit of £19 per week and they already transferred to my account,

I am worried as i didnot mentioned about these two benefit i received this week to home office, as i received after sending my wife application,
what should i do ? should i stop these benefits? will it effect my wife application?Should i tell Home office?
in all benefit claim i mentioned wife is not entitled for public funds

My financial position is not strong and earning little bit, i was not planning to send wife application as she have visa up to jan 2013, but becs of rule changing on 9th july i have to send

Need your help

Many thanks
