My Aunt is on illness benefit with 6 months can she rent out 2 rooms in her house to help with bills or will it affect her illness benefit weekly payments under new rules ?
Illness Benefit is not a means tested payment, so it is not connected in any way to renting out rooms. It is a taxable income for Revenue, ie it is taken into account, which may or may not mean tax is payable depending on your Aunt's overall income etc.
