Vattenfall is to enter the UK domestic energy market as it buys a Bournemouth-based supplier.
iSupplyEnergy provides gas and electricity to more than 120,000 customers and employs 170 people.
The move follows the Swedish utility’s announcement last month that it has started to sell renewable energy to UK businesses.
Vattenfall said no jobs at iSupplyEnergy are at risk and its headquarters will remain in Bournemouth.
Martijn Hagens, Vattenfall’s Senior Vice President for Customers & Solutions said: “We have a strong and growing customer focused company with more than eight million power, gas and heat customers in norther Europe.
“We are convinced our acquisition of iSupplyEnergy will be good for our new customers as we will combine our experience and increasingly smart and fossil-fuel free energy solutions with iSupplyEnergy’s strong, nimble, digitalised and transparent customer service.”
French utility ENGIE also recently joined the UK home energy market.
