EDF acquires iSupplyEnergy's customer contracts
Today it was announced that EDF will be acquiring iSupplyEnergy's customer contracts. We look forward to welcoming these customers to EDF, and are working closely with iSupplyEnergy to ensure a smooth transition.
Please find our statement below, to be attributed to an EDF spokesperson:
“As the largest producer of low carbon energy in the country, EDF is committed to growing its retail business in the UK so it can support as many customers as possible on the journey to net zero emissions.
"iSupplyEnergy customers will be able to benefit from low carbon energy alongside our industry-leading customer service, and do not need to do anything at this time. Their supply will continue as normal and we will be in touch with them shortly to explain any new arrangements.”
Notes to editors:
- Approximately 190,000 of iSupplyEnergy’s residential customer contracts will be transferred to EDF in the coming months.
- EDF is only acquiring iSupplyEnergy’s residential customer base and is not acquiring iSupplyEnergy.
- Customers do not need to do anything. They will remain on same terms, and their prices will not go up as a result of their contracts moving to EDF. Existing Direct Debits will be automatically transferred to EDF for the same amount / dates.
- EDF is the UK’s largest producer of low-carbon electricity, meeting around one-fifth of the country’s demand and supplying millions of customers with electricity and gas. It generates low carbon electricity from eight nuclear power stations, more than 30 onshore wind farms and two offshore wind farms.
About EDF
EDF is driving the transition towards An Electric Britain – a secure, affordable, low-carbon future for everyone. As Britain’s biggest generator of zero carbon electricity, we are investing more than £100 million weekly in Britain’s electricity infrastructure. We supply millions of customers with electricity and help homes and businesses switch to electricity for heating, transport and industrial processes.
We operate five nuclear power stations and more than 35 onshore wind farms and three offshore wind farms. Since 2009, EDF has invested almost £9 billion in the nuclear fleet to improve reliability and extend station lifetimes. The five generating stations currently supply about 12% of the UK’s electricity demand.
EDF is building the UK's nuclear renaissance with the construction of a new nuclear power station at Hinkley Point C. We are a minority investor (12.5%) in and major supplier to a replica plant at Sizewell C in Suffolk. Hinkley Point C and Sizewell C will provide low carbon electricity to meet 14% of UK demand and power around 12 million homes. EDF Group companies Framatome and Arabelle Solutions have a presence in the UK and manufacture critical equipment such as reactor pressure vessels and turbines.
