Understanding SSDI in Simple Terms

Social Security Disability Insurance (SSDI) provides monthly income for people who can no longer work due to serious medical conditions. The rules are strict, and the process can be confusing. We help you understand whether you may qualify, what Social Security looks for, and how to apply with fewer mistakes.

What SSDI Helps With

SSDI is based on your work history and payroll taxes you’ve paid over time. To qualify, Social Security must agree that your condition prevents you from working full-time for at least 12 months or is expected to result in death.

SSDI May Apply to You If…

You have worked long enough to earn work credits and can no longer work full-time because of a medical condition that is expected to last at least 12 months or longer. If your health limits your ability to work, SSDI may provide monthly income support.

SSDI vs SSI - The Quick Difference

SSDI is based on your work history and earnings, while SSI provides need-based support for people with low income and few resources.

Success Stories

London Disability did a great job fighting for me. Although I was denied several times, they did not give up fighting to pursue what they knew was the right thing. If you’re in a tough spot with no help, in pain and can’t function, if all doors have closed and you feel like giving up, don’t, just pick up the phone and call London Disability, because it’s time you had a positive change.

I’m so glad London Disability reached out to me about my disability. I was awarded and won my case from Social Security. It took only a few months, and my case manager was amazing. Thank you, thank you. If you need help with your disability, look no further than London Disability.

I just wanted to say that my team from London Disability is the best. They have been fighting for my case since 2020 and not once did they give up on me when I was denied twice. My case manager called me with the best news ever that we had won our case. I was so happy and she really made my day.
-K.M.
I had a great experience with London Disability. I was two years without any income. They listened to my case, understood my issues, and handled it from there. I couldn’t do it without you. It’s very much appreciated. Great job.
