Who is EDF?

EDF, in its current iteration, was formed in 2002 when French state-owned utility provider, Électricité de France, bought Seeboard plc, London Electricity plc, and SWEB Energy plc.

Over the years, EDF Energy expanded its operations through further acquisitions and investments. It acquired British Energy in 2009, significantly increasing its presence in the UK's nuclear power sector. British Energy operated several nuclear power stations across the country, making EDF Energy a major player in nuclear energy generation in Great Britain.

Thanks to its sustained investment in nuclear power stations, EDF has grown into Britain's biggest producer of zero carbon electricity, with almost 60% of its electric power stemming from nuclear sources.

As a division of EDF Energy, EDF Business Energy benefits from the company's extensive experience and resources in the energy sector. It leverages EDF's diverse energy generation portfolio, which includes nuclear, gas, coal, wind, and solar power assets, to offer reliable and sustainable energy solutions to businesses of all sizes.

How to cancel EDF Business Energy

Unlike domestic contracts, business energy contracts do not come with cooling-off periods.

This means you are obligated to fulfil the full length of your fixed rate business energy contract after the contract has been signed.

If you want to leave EDF Energy before the end of your business contract, you will have to pay a premium, the amount of which will be determined by EDF. Contact EDF to find out more.

When your contract enters its final 60 days, EDF will provide you with your renewal options. If they are not to your satisfaction, you can call EDF to negotiate your renewal.

If you wish to leave, you must give more than 30 days’ notice and provide your new supplier with your final meter readings. They will pass these on to EDF, which will use them to calculate your final bill. This way, your bill with your new supplier will begin the day after your final bill with EDF finishes.
