Of course it’s possible.
I just used the ‘Entitled To’ calculator.
A family with 2 non working parents, where 1 is a carer and 1 on PIP, with 2 kids claiming DLA, is entitled to £40,000 in benefits per year.
£2300 UC
£360 carers
£145 council tax support
£262 child benefit
£4000 PIP
In the handful of families I mentioned above, there is a bit more at play (such as 3 DC on DLA, or both parents receiving PIP, or 1 parent caring for the other). So that would in theory be more.
Do you dispute the figures above?
