Hi Lynz,
The Severe Disability Premium does not exist in Universal Credit. If you were entitled to a Severe Disability Premium on Income Support, income-related Employment and Support Allowance (ESA), or income-related Jobseeker's Allowance at the time you claimed Universal Credit, you are entitled to transitional protection.
There is also a brilliant website called Turn2us (see link below) who may be able to help advise you.
