If a mistake has occurred and you have been over paid on any benefit and you have taken all reasonable steps to keep the dept up to date AND CAN PROVE THAT.
Then it is what is called an official error.
I was in the position of having my income support stopped, without warning, no letter etc.
I am a carer for my wife.
Turns out I was paid it for 3 years and was not entitled to it.
Quite right,when they showed me the figures they were right.
But that was due to some prat not transferring info in their offices.
I was then told that we were under investigation for fraud to the tune of 5700 pounds.
As my wife keeps everything she ever gets we proved quickly it was their fault.
They still tried it on and wanted payment.
Once I enlisted the help of a solicitor and got the crack, official errors are very common and cannot be clawed back if it is not your fault, then their attitude changed.
To the extent I got an apology and compensation.
So if any DWP dept is getting heavy and you feel you are in the right, plus sorry to say it again, you can prove it.
Fight it, you do have rights.
