Housekeeping money from adult children - what does it cover?

[Anotherloverholeinyohead]

Curious to know what arrangements other people have.

My 20 year old son gives me £150 per month. He does not drive yet (taking lessons though) so £100 of that is to cover the fuel costs of me driving him to work. The other £50 is a token contribution to the household. He is saving for a car/insurance and is building up work tools which he needs to pay for.

Talking to his friend yesterday - he pays £100 housekeeping money plus buys all his own food/toiletries/washing powder etc.

I don't want to profit from my adult child living at home and if I thought he was taking the mick with the situation I would review it but, just curious as to other peoples set up

It doesn't matter what their "keep" covers or doesn't cover. They need to contribute to the cost of having a roof over their head for starters. DDs both paid £50 pw which then went up to £70pw due to COL.

They eat some meals with us, sometimes they cook their own. They use the washing machine - sometimes I do their washing in with ours, sometimes I don't.
