Changed job and have a universal credit claim running. I would be entitled to a small amount, and importantly help with some childcare costs. However my employment pay date will be just after my claim period ends so I will look like I haven't earned anything in my first month. This means I will likely get the full UC amount as if I had no income at the same time as recieving a full month's pay. Is this an overpayment or simply how the system works re claim period/dates?
