Might be a useful exercise to ask Chat GPT. I just did and said they must cover costs, but not looking for profit.
The response was:
Fuel - £10-£20 per week
Water - £3-£5 per week
Budget groceries for full meals - £30-£50
Sundries (eg loo roll) - £3-£5
So between £46-£80 per week and they must obviously pay any lost Council Tax discount on top of that - as I suspect OP is single. Obviously OP will know whether she is feeding them budget food, ready meals or what to judge accordingly.
The "system" offered to do further thinking on that topic.
Conundrum regrding friendship.
