ok, sorry to disagree with you scooby, but I do
They will do a rent determination. They willl look at how many bedrooms the property has, and how many he needs. Non-resident children are not normally counted.
I have never ever ever never known them pay out for a house that was bigger than they felt was needed, although occasionally they will do a DHP top up. This did used to be my job!
Non-resident kids were not, when I was working a year ago, counted towards the no of bedrooms allowed. I think this is massively unfair as it hinders access. But I remember it being a problem.
What they will normally do is to pay you the amount they'd normally pay out for a house that they think is big enough for your family, and you'd have to make up the difference.
Also-you know the rules re kids and bedrooms, yes? 2 under 10's or 2 over 10s of same sex per bedroom?
They are normally very strict. Eg, round here, its common for houses to have a dining room and a reception room. The kitchem will be cat-swingingly small. The will often expect the dining room to be used as a bedroom. Thats how strict they can be.
I'm still hoping scooby is right and I'm wrong, though. Nutty-get on to the council!
