The mode of collecting electricity charges varies in different service apartments. While electricity charges are covered by the rental for some service apartments, some tenants are required to pay the charges to the landlords (instead of CLP). As to whether the tenant of a service apartment is eligible for the relief, it will be subject to factors such as having a "separate electricity meter of an electricity company" installed in that apartment, holding a residential electricity account for the power supply, as well as the agreement between the tenant and the landlord.
