EDF prices and tariffs

There is a wide range of EDF energy tariffs available at any one time, including fixed and variable plans.

How EDF prices have changed in 2022

EDF energy tariffs are subject to Ofgem's energy price cap. The price cap sets the maximum rate suppliers can charge for average use on standard variable or default tariffs - which are typically the most expensive type of energy plan.

Energy wholesale prices rose significantly from the autumn of 2021 due to various factors such as low wind generation and low reserves of gas. This meant that it cost energy suppliers much more to buy energy than it previously did, so Ofgem raised the energy price cap level (which caps the unit rates customers pay) to its highest ever level of £1,971 to help them cover their costs.

EDF therefore increased its standard variable tariff rates from £1,277.22 to £1,970.44, effective from April 2022.

EDF was the first of the big six energy suppliers to announce its new rates after an increase to the price cap was announced in August 2021. In line with the new cap level, EDF energy prices will increase by 12% from October 2021 on standard variable tariffs. This means the average customer on a standard variable tariff from EDF will now pay £1,277 a year - an average price rise of £139 per year. The table below shows recent changes to EDF Energy prices, alongside changes by the rest of the big six energy suppliers:

How EDF prices changed previously

EDF was also the first of the big six energy suppliers to announce its new rates after the Ofgem energy price cap was raised in February 2021. EDF energy prices increased by 9% from April 2021 on standard variable tariffs with the average customer on a standard variable tariff paying pay £1,138 a year. In line with a drop in the energy price cap level announced in August 2020, EDF energy prices dropped by 7% from October 2020 on standard variable tariffs. This translated into an average price drop of £84 per year.

EDF prices on standard variable tariffs previously dropped by just over 1% in April 2020, also in line with a reduced energy price cap. EDF announced a price drop of 6% for standard variable tariff customers in August 2019. EDF dropped slightly further than it had to: its new average price, effective from 1 October 2019, was £1,177. In February 2019, EDF energy prices rose by 10% on standard variable tariffs, effective 1 April 2019. The supplier increased rates to the energy price cap level of £1,254. The last EDF price rise before this was announced in April 2018 — a 1.4% price rise for standard variable rate tariff electricity customers. The increase, which resulted in a £16 per year hike in customer bills, went into effect 7 June 2018 and followed days after big six rival British Gas announced a dual fuel price rise of 5.5%.

EDF gas and electricity

In total, EDF supplies energy to around 5.5 million customers, both businesses and households, making it the nation's largest supplier of electricity by volume. EDF produces around one-fifth of the UK's electricity from a variety of sources, including combined heat and power plants and wind farms, as well as the more traditional gas, coal and nuclear power stations.

EDF and Zog Energy

Zog Energy went bust as a result of the energy market crisis in December 2021. Its 11,700 customers were transferred to EDF under the Supplier of Last Resort system.

EDF and Green Network Energy

EDF was appointed as the supplier of last resort when Green Network Energy ceased trading in January 2021. Green Network Energy's 360,000 customers were automatically transferred to EDF.

EDF and iSupplyEnergy

In March 2020, EDF took on around 190,000 of iSupplyEnergy's customer accounts, after iSupplyEnergy exited the UK energy market.

EDF and Solarplicity

In August 2019, EDF took on approximately 8,000 customers from Solarplicity after the small supplier ceased trading.

EDF renewable energy

EDF, as well as being one of the biggest energy suppliers in the UK overall, is also the UK's biggest producer of low-carbon electricity thanks to its operation of 10 nuclear power plants around the UK. It was also the energy and sustainability partner of the London 2012 Olympic and Paralympic games.

Is EDF going bust?

The energy market is challenging and unpredictable at the moment and there is a certain level of risk to some suppliers - find out why in our energy market Q&A guide.
