Managed migration and cost of living issues

Dianimoon

Hope someone can advise. Long term ESA in support group with SDP - managed migration to UC. If Transitional Protection eroded by uplift in other benefits that means overall benefits wont increase for 5 years. for example if get £150 per month TP and benefits uplifted £30 per month annually, it will take 5 years to erode which means no increase in total benefits for 5 years. If still on legacy benefits next year would get an extra £600 per year but now will receive nothing - how is this even legal let alone how are you meant to cope with cost of living issues etc.

Has this been tested in Triunal/Court does anyone know

Thanks for your help
