We have a daughter who has received higher rate DLA for approximately 3 years. In November 2023, we applied for UC and were awarded the relevant amount. Both myself and my wife work full time and we only receive a small amount, but it pays for my daughters riding lessons each week which makes a huge difference to her wellbeing. About 10 days ago we were contacted by UC and informed they may have underpaid us due to not taking account of the extra room we should have been awarded in line with my daughter’s disability. I had to complete a very quick tick box form and a week later we received a further communication saying we had been awarded an extra room and were entitled to backdating. I must admit if they hadn’t of contacted us, I’d never have known! From what I have read, we now have to wait for a further letter to confirm the amount to be backdated and when we should receive the funds. How long does it usually take from getting the first letter confirming it’s been approved to getting the second letter with the details of backdated money?
