Surely it will unfairly penalise larger families. The papers ppoint out that a couple with 3 chldren will need a house less than £180 per week to be within the cap while a couple with 4 children will need a house costing less than £130 a week. Given rents for 3 bed houses here are £800 per month how is this going to work? It seems to say either the children go without or the couple would be better off splitting up.
