It's not an extra charge. If you don't claim benefits but you do rent a council home, then you are just paying the rent that has been decided as accurate for the property you live in.
There won't be any extra charge for people who already pay their own rent.
People will just be given less money in housing benefit, if they claim it.
People will no longer be able to claim enough money to cover the rent in a three bedroom house if they only need a two bedroom house.
Housing benefit will still pay for what people actually need in the vast majority of cases.
So actually Strokethecat, it is only people who claim benefits that will be affected by this.
Those who rent will pay for the size of the property they rent, just the same as people who buy will pay for the size of property they buy, even if the smallest bedroom is tiny.
