Council Tax reduction - Possible backdating.

FirmSpear

We initially lost entitlement in September 2021 after I started working. We queried this at the time and due to the total income of my wages and our universal credit, the council deemed that we did not qualify for any reduction. We left it at this as they provided the income bandings to show our income was indeed above the threshold. We had already had a disabled reduction discount successfully applied.

We have recently looked into this again as we have recently moved house and believe that the council did not apply their own rules regarding income disregards and included carers allowance/carers element of UC, the LCWRA element of UC and the support component of the New-style ESA. These have been a constant element since September 2021. So if these were disregarded at the time we would have been eligible for the past three years.

We have reapplied for the council tax reduction providing our latest UC statement as requested (we were not asked for this previously). 
If successful, would there be anyway that we could apply for this to be backdated to the initial query even though the council state that they will not be able to backdate it?

Thanks in advance for any advice.
