You need to apply for one of the benefits as soon as possible.
JSA i know you cant get backdated, I.S you can.
With Income Support you will be paid at what they call appeal rate rate, at the moment its £51.45. If you make a claim to I.S then ask for backdating to the day after you failed your PCA.
Few questions
Do you have DLA? .
Do you have a pension ?
Do you have saving over 16K?
all three could effect your claim
You Can claim ESA and ask for back dating up to three months, but you would need a backdated medical certificate off your doctor to cover this period
Jobcentre Plus - Making a new or repeat claim
If you get awarded any of these then you should get housing benefit.
If you win your appeal you can go back on I.B
appeals can take months longest I Have seen is eighteen months but I dont think that is a record
