Tariffs are assigned to each offtake point on the basis of an inspection report, after an on-site technology check, and vary according to the technology used and the power input. If the property is an apartment or office with classic appliances such as a gas or electric stove, washing machine or television, the standard tariff applies. However, changing the type of heating your appliance uses (electric boiler instead of gas, installing a heat pump) or purchasing an electric car and setting up a charging station is a fundamental change.
