Finding DSS properties hard to locate

Hi I’m needing a 1 bed flat or house or a studio flat in the newham area.
I am currently on benefits and I am signed off due to medical issues.
I have looked and it just seems I can’t find hardly any.
Is anyone able to point me in a direction where I’ll be able to find more?
My budget is £1100 pcm
My area is newham but e15,e16 & e6
