DLA PIP CARERS BENEFITS

Hi sorry if not allowed but I have a question about Pips DLA and carers
I have written to local authorities because we have been council tenants for over 45 years and for the last few years asked for DHP it is where the local council because of family circumstances, mental health, and poor health in general all 3 bedrooms in our house is still being used............ well short cut of it is I had to send them a financial list of out in and outgoings. and our cash going into the banks this is all benefits ie ESA Carers PIPS, well I just got this email and it says

When looking at your expenditure and after your rent shortfall is paid you still have £150 per week disposable income. but this £150 is coming from PIPS DLA Or even Carers so surely they are not allowed to count this in with the Expenditure Incoming money?? as it is a disablement benefit? Please understand I am not looking for any help about the so-called Bedroom Tax part of this question but only asking if the local council can take any of the PIP / DLA or carers Thank you very much for reading

Thank you Gordon
I been looking for this tonight
To reflect the Court’s ruling the Government has changed the law to create further exemptions for carers from the Bedroom Tax. This means that from the 1st of April 2017
it was made by the 09 November 2016

Today, in a landmark ruling, the Supreme Court has ruled in favour I am hoping to appeal this anyway. thank you
