My landlord in Jingui Community, Tianxin District, Changsha, charged me 1 yuan for electricity and 4 yuan for water. Is it reasonable for the landlord to charge me?

The landlord charged me 1 yuan for electricity and 4 yuan for water, which was unreasonable. At present, residents' electricity charges are charged in grades, and landlords should not charge renters more than the third grade. However, there is no clear legal provision in this respect, which should be settled through consultation with the landlord. For reference only, thank you.
