I have in the past sent a request back to a Local Authority on the grounds that it would cause Financial Hardship
Similar scenario in that max deductions were already being taken from her Income Support entitlement and she was unable to meet the top up for her rent.
She was been granted a DHP by us because of this, and then the request was made to recover HB op on behalf of another authority.
I know that recovering from ongoing entitlement is considered good practice, and I know that if you had a HB overpayment of your own you would just recover it from ongoing entitlement – however you do have the discretion not to on the grounds of Financial Hardhsip.
I do believe that where there are already max deductions being taken from DWP benefits that the LA should either wait and try again when the deductions have gone down or if the deductions are clearly going to take years then drioudly consider writing the debt off as the customer simply does not have the means to pay it.
