For people who rely on benefits, a change of circumstances can be anxiety inducing.
The only positive change in my case, was when I started working.
Instead I only had to worry about upfront childcare costs and the cost of travel to and from work. At least now, the costs of childcare will be paid upfront.
Changes in other circumstances and notifying the DWP is the cause of anguish. Your account is often on hold until an appointment for paperwork checking is completed. When there is a rent increase, but no actual increase to your award because of no increase to the local housing allowance, then the account is still put on hold until further documentation is submitted.
