Not necessarily.
If landlords could get a fair rate from a government scheme they would prefer the lower risk option and kick out renting voters onto the streets. The closer the rate is to the rental market the faster this would occur.
As it stands this covers the "inconvenience" of renting out a room and sharing the facilities. The government is focusing on the temporary nature of this event and knowing that people will be transitory. The government don't want people getting addicted to the handouts too. It also places an emphasis on the home owner to interact (through shared cooking spaces, lounge etc) to integrate better. Only that idea gets shot down as landlords will stack and rack Ukrainian families purely to get the payout.
So with this in mind - this is more of "rent out your rooms" than rent a full property. Great for those rich people that have more rooms to throw a stick at (especially after the trend to home working now means any 'idle' rooms are consumed "hybrid working" without being reimbursed by employers).
This smells of Patel being dragged face down by the foot with vampire nails and teeth scratching the cement, hissing all the way..
