Universal Credit can ask for bank statements. They will ask if something smells fishy. They won’t ask if you’re a model citizen with boring transactions.
If they do, don’t panic. Upload the PDF, delete your weird purchases, and move on. Remember: Steve the DWP worker is probably just as bored as you are.
So, can they ask? Yes. Will they find your secret McDonald’s habit? Only if you paid with a cheque. And honestly, if you’re hiding money in a shoebox under your bed, you’re safe—for now. The government hasn’t invented a scanner for that yet. Go eat your toast in peace.
