That is one of my worries when I die, that my wife will have to claim HB to get by. Our rent is £600/m.
Her pension and half my company pension will give her a total of about £850/m.
My youngest son lives with us, but he is hoping to start training soon, for £5000/pa plus borrowings.
We have no savings at all.
Three bedroom, so bedroom tax will kick in sometime.
