Can the property increase the price and charge electricity?

I can't.

Lawyer's analysis

The water and electricity charges collected by residential properties cannot be charged at a higher price.

Entrusted by the water supply and power supply unit, the property company can collect the water and electricity charges from the owners, but the property company collects the water and electricity charges from the owners on behalf of the water supply company and the power supply company.

Property companies shall implement the price standards of water supply and power supply departments, and shall not, in violation of the stipulations of the property service contract or the provisions of laws, regulations and departmental rules, expand the charging scope, raise the charging standards or repeat the charging without authorization.
