Oomi
We brought together the best operators in the industry in order to develop and offer more advantageous energy services to Finns.
Seamless together
Two familiar energy service companies, Oomi and Lumme Energia, are now one. We are the leading energy services company in Finland, with more than 800,000 customers across the country. We make everyday life and energy services easier, more sustainable and smoother for people, businesses and communities. We offer our customers a wide range of services, a superior customer experience and strong expertise – with the same familiar, people-oriented approach.
We are where everyday life happens. In homes, workplaces and communities, where people rejoice, work and dream together. Our customers trust us each and every day. And our intention is to live up to that trust.
Our customers now have a stronger, Finnish-owned partner they can rely on in the changing energy environment. Oomi is owned by local energy companies from all over Finland. At heart, we are a local, now more national, energy services company.
The larger size will allow customers to benefit from better services and competitive electricity contracts in a highly competitive sector. This is not just a merger of two companies, but an opportunity to build something new together. By combining their resources, Oomi and Lumme Energia can offer more value to their customers and better meet their changing needs. Lumme Energia and Oomi share the same values and highly skilled staff, and by combining our strengths and development projects, we can bring completely new solutions to the market.
As such, we will continue our journey together, constantly evolving – together, seamlessly.
Good to know for customers switching over from Lumme Energia
As a result of the corporate acquisition, all agreements, products and services concluded with Lumme Energia have been transferred to Oomi, as such, as of 1 January 2026. The change applies to all consumer and business customers of Lumme Energia. The merger will not affect the contracts of Lumme Energia’s customers, their terms and conditions, validity periods or prices.
Lumme Energia will continue to handle customer service and billing for the time being as before, and customer service contact details will remain unchanged. You can still use Lumme Energia’s service channels as usual.
Good to know for Oomi customers
The merger will not affect the contracts of Oomi customers, their terms, conditions, durations or prices.
We want to serve
Oomi already has more than 800,000 satisfied customers. We exist for our customers.
We take responsibility for our environment
We are part of a continuum of generations in small and large municipalities. Because of this, it is a matter of honour for us to do our part in taking care of the well-being of nature, the community and companies.
More together
We believe in the power of cooperation; together we have broader shoulders both for taking care of everyday routines and developing new things.
