Universal Credit and benefit payment changes prompt charity warnings. (PA) Over half a million people in the UK have been warned of changes to the benefit system for those claiming disability allowance. Ministers have recently lifted a two-year ban on people who claim ‘Severe Disability Premiums’ moving to Universal Credit. People on old-style benefits can now switch to Universal Credit if they want to but some may also be moved to the new method if they have a change in circumstances such as moving house or a relationship. Once people apply for Universal Credit, they lose the right to claim any old-style benefits and cannot reverse that decision.
