Fucks sake, the ignorance about how those dependent on UC is astounding.
You don't get all your rent covered. You get your LHA idea of what your rent should be, and no more. It is in many cases around 150.00 to 200.00 LESS than your actual rent. You make up the shortfall from the 400 quid meant to cover basic living costs - utilities and food, unless you're in the "unable to work" category which gives you an extra 300.00 or so if you are a single person. You may qualify for council tax relief.
If you achieve the holy grail of employment, say a "full time" job on minimum wage, any benefit is cancelled out by the cost of council tax and getting to your job.
Trust me, I know. I've done every calculation I can to figure out how to improve my situation at knocking on 57, having had four years of curve balls, not limited to but including my DP dying unexpectedly, losing my business due to economic decline, having to move from the house we shared into a tiny one bed flat out of town with all those associated costs, plus at the same time navigating my Dad's homelessness and declining health following my SM going batshit and ending their marriage at 85 and 82 respectively, then this year in a three month period I lost my Dad, my dementia ridden MIL and my Uncle.
So I apologise for my "bad choices" and the fact that my age, gaps in CV and a host of other impediments mean I'm leaching off the tax payer and I'm stuck in Groundhog Day.
And finding a guarantor, even for a bedsit or HMO isn't easy due to income thresholds, home owning requirements, and people naturally unwilling to take on the liability of someone else's rent.
The housing market is broken.
