Company history

iSupply Energy was purchased by the Swedish energy company, Vattenfall, in June 2017.

Based on the south coast of England, in Bournemouth, the firm initially only offered electricity. This later changed, when they expanded to offering gas and dual fuel tariff options in 2015.

It is estimated that the company has more than 120,000 UK customers, they employ around 170 people throughout their UK operations to manage this base.

iSupply Energy were previously a UK-owned independent supplier, this changed in June 2017 when Vattenfall, a large Swedish energy provider acquired the company. Vattenfall is a Swedish conglomerate that has operations throughout Sweden, Germany, Finland, Denmark and Netherlands.

Vattenfall has heavily invested in energy production throughout Europe, their financial backing will help iSupply reach their supply targets. iSupply’s renewable energy generation will benefit from the parent company’s large investments in onshore and offshore wind farms.
