How do I calculate the tax credit if I move between 1 January and 30 April 2023?

Add together your electricity expenses for the old and the new apartment between 1 January and 30 April 2023. If you are moving, for example, on 1 March 2023, calculate your electricity expenses for the old home for the period 1 January - 28 February and your electricity charges for the new home for the period 1 March - 30 April.
