Visma Tampuuri, Kamstrup and EnerKey into a cooperation – simplifying water invoicing for residential properties

Visma Tampuuri, Kamstrup and EnerKey work together to provide residential property sector with an effortless service package that enables consumption-based water invoicing by combining the market leading solutions. The aim of the cooperation is to position the service package as the standard solution for the Finnish market. International expansion possibilities are also being actively explored.

According to the EU Energy Efficiency Directive set in 2018, water invoicing for residential properties must be apartment-specific and based on real consumption. The invoicing is based on both, the water consumed, and the energy used to heat it. Information on water and energy consumption must also be provided to the resident.

The Finnish Parliament passed a law based on the EU Energy Efficiency Directive in November 2020. In future, apartment-specific water meters must be used as the basis for invoicing. In Finland, the installation of water meters became mandatory in new buildings in 2011 and in connection with renovating residential properties in 2013.

“For many of our customers, this legal reform means changing their current practices. We want to support our customers and continue to make water invoicing easy and straightforward. The partnership with EnerKey and Kamstrup makes this possible in the best possible way,” says Erkki Ahonen, Visma Tampuuri’s Partnership Manager.

The cooperation consists of three different areas, which are packaged seamlessly for the customers. Kamstrup designs and implements the necessary measurement solutions for water reading and consumption data collection. EnerKey provides the platform for energy management, data visualization and automated consumption alerts. The services are provided to the end customer through Visma Tampuuri’s comprehensive property management, which includes tenant management and water invoicing services.

“The new EU regulation is being implemented in national legislation, with the aim of improving consumers’ opportunities to influence the sustainable use of energy and water. What you can measure, you can also manage. Monetary costs act as a good consultant in sustainable resource consumption. The service package, designed and implemented in cooperation, is an easy turnkey solution answering the needs of forerunners in the residential property sector,” states EnerKey’s Jaakko Huhta, Vice President, Sales and Business Development.
