Hi @CardiffGirlInEssex, I'm hoping to goodness that these people change their minds, but if your dad is absolutely going to come home the door locks need to be changed to ones with a thumb turn on the inside. Before we had one at MIL home she left key in the lock, had a fall and we couldn't get in! Your mum will then not be able to leave a key in the door and lock carers out. You will also need a key safe outside the door so carers can let themselves in if necessary. Your local authority will have a company they use for things like this - your dad will be able to give consent even if your mum does not. You may even get it free if either of them are on certain benefits (I think attendance allowance is included).
