The cost of sales and contracted work decreased by 27 million compared with 2018.

The decrease in the cost of sales and contracted work was caused mainly by the sale of Joulz Diensten and Joulz Energy Solutions, with an impact of around 49 million, as well as a decrease in the purchase costs of energy of some 5 million.

This decrease was partly offset by a cost increase relating to external costs, excluding the impact of Joulz Diensten and Joulz Energy Solutions, of some 21 million and higher cost of material of 4 million.
