EDF reviews, tariffs and information

About EDF

EDF is the UK’s largest producer of low-carbon electricity, the biggest supplier of electricity by volume in Great Britain. It owns and operates eight nuclear power stations and 35 wind farms (as well as other renewable sources) that generate that low-carbon electricity.

Among other things, it offers a range of fixed and bundled tariffs for electricity and gas; a range of connected home products (such as smart thermostats) to help you take your first step towards a smarter home; and heating and boiler insurance cover.

EDF was created in 2003, five years after French energy company EDF Group (Électricité de France) bought Seeboard, London Energy and SWEB Energy.

How EDF prices have changed in 2021

EDF was the first of the big six energy suppliers to announce its new rates after an increase to the Ofgem energy 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.

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%.
