ESA, JSA and UC

Hello,

I have been very sick over the past year and have stopped all of my jobs and responsibilities due to my health. My employer can longer pay me sick pay. So they said they would give me an SSP form to take to the job centre.

I have the full-year NI contributions over the past 10 years.

This is my first time applying for any kind of benefit, so I am a bit of a "nube".

My question is, what benefit should I go about applying for first? ESA, JSA, or UC? Is there a specific order to be entitled? Should I apply for all of them?

I am hesitant to apply for UC first because I have not moved out of my current accommodation (living with the father of my children but we are separated and I am single) (See previous post for more info on this if curious). I am still going to apply for UC but I'd imagine it'll be a bit of a battle.

Any guidance would be much appreciated.

Warmest regards,
BH
