How we calculate your monthly payment

We estimate your annual consumption based on your previous usage and your chosen plan, calculate the expected amount for the next 12 months, and divide it into 12 equal payments. For example, if we estimate an annual cost of €600, you would pay a monthly instalment of €50. At the end of the 12 months, we compare the amount paid with your actual bills and adjust the difference, either upwards or downwards.
