Forums Chit Chat Charging Your Child Rent Reply To: Charging Your Child Rent July 9, 2018 at 3:20 pm #367 Suee 10 Posts I think I used to pay £200 a month and that was as soon as I had left uni and was in employment. However whatever my mum charged they would have taken earnings into consideration, i.e. she wouldn’t have charged £200 if I was only bringing home a small amount. They worked it out on extra water charge having me there (they would see the increase in water bill compared to when I was at uni!) and food etc. They fed and watered me, and mum would offer to do my washing if I left it out for her.
