The site is in Finnish and Swedish only, but the contract terms are published in English.
Compare the same contract type and yearly electricity use. A fixed price, a spot-price margin and a hybrid price are different products. Include the monthly fee and any commitment, and check whether the offer covers your address. Electricity distribution remains with your local grid company when you change seller.
The service and contract facts come from Oomi's and Vattenfall's own websites, checked on 8 November 2026. Sources are linked with each provider. “Not confirmed” means the source did not establish an answer; it does not mean “no”. Live plan tables, when available, use separately refreshed prices.
