I'm consider hiring a cleaner for about 3 hours a week to do some of the weekly things I hate don't have time to do, but what should I be asking for? The one in the pipeline is self employed, should I ask for references/DBS check? Will she have these? I don't want to offend but at the same time I'm wary of a stranger coming to the house. DH would be here most of the time but obviously won't be following her to every room
