Our EDF Energy Verdict
In our experience, EDF Energy operates a professional, reliable and consistent service when it comes to handling new customer energy supply applications.
We like the transparency of their pricing. Their advertising, featuring Zingy, is also pretty cool.
From late 2012 EDF Energy withdrew exit penalties from their energy tariffs. Unfortunately, due to the pressure of competition and the rate of energy switching
in the market, exit penalties have come back on a number of their tariffs. As this is now a feature of most fixed term tariffs in the market, this is not
something that we can hold against them.
It probably goes without saying but is worth pointing out nevertheless that, given the financial strength of the group, there negligible financial risk to being on supply with EDF Energy.
We have awarded EDF Energy a 4 star service rating (from 5) and are happy to recommend them to customers.

About EDF Energy
EDF Energy is commonly referred to as one of the Big 6 energy suppliers supplying the domestic energy market. However, its operations extend well beyond just energy supply.
Although the supply business was incorporated back in 1988, the origins of the current UK group date back in the early 2000's when it was established through a series of mergers and acquisitions that brought together the assets of several energy businesses - London Electricity, SEEBOARD, SWEB Energy and the former Virgin Energy.
Today EDF Energy in the UK is involved in the supply of gas and electricity to commercial, residential and industrial customers and the generation of electricity through a portfolio of generation assets including nuclear, coal, gas and renewable generation.
In generation it owns and operates one gas fired power station (West Burton B CCGT), 2 coal fired power stations (Cottam, West Burton A) and 8 nuclear power stations (Dungeness B, Hartlepool, Heysham 1, Heysham 2, Hinckley Point B, Hunterston B, Sizewell B and Torness). Seven of these are Advanced Gas-Cooled Reactors (AGCRs) and the eight is a Pressurised Water Reactor (PWR).
The company operates 2 gas storage facilities in Cheshire.
EDF Energy is also active in renewable generation. It currently operates 31 wind farm sites and has more coming on stream over the next few years.
In the supply business, EDF Energy had 3.3 million electricity customer accounts and 2.0 million gas customer accounts at the end of 2015. This was a slight fall in customers on 2014.
Going forwards EDF Energy, in partnership with China General Nuclear Corporation, is planning to build new nuclear reactors at Hinckley Point in Somerset, and to work together towards developing proposals for nuclear plants at Sizewell in Suffolk and Hinckley Point in Essex. EDF Energy is also proposing to develop a gas power station at Sutton Bridge.
Who Owns EDF Energy?
EDF Energy is owned by the French government under the Èlectricitè de France (EDF) Group, one of the largest diversified energy companies in the world. At end 2015, the group had net assets of 279 billion Euros.

Fuel Mix Disclosure
All suppliers, including EDF Energy, are required to provide information about the mix of fuels they use to generate the electricity they supply to their customers. They also need to disclose the environmental impact of this fuel mix.
This information is known as the Fuel Mix Disclosure and is published annually.
The table below shows the EDF Energy Fuel Mix Disclosure for the period 1 April 2017 to 31 March 2018.
| Energy Source | EDF Energy | UK Average |
| Coal | 7.55% | 7.64% |
| Natural gas | 9.39% | 9.39% |
| Nuclear | 71.21% | 20.01% |
| Renewables | 11.66% | 29.04% |
| Other fuels | 0.19% | 2.07% |
| CO2 emissions | 104 g/kWh | 225 g/kWh |
| High-level radioactive waste | 0.0050 g/kWh | 0.0014 g/kWh |

Compared to the UK average, EDF Energy supplies a much higher proportion of energy generated from nuclear - it is a significant generator of nuclear
power - and consequently a much lower proportion of electricity generated from natural gas and renewables. Its CO2 emissions are well below the UK average
largely due to low carbon emissions from nuclear power.
Compared to the preceding year, EDF Energy has reduced its supply of electricity generated from nuclear and increased the proportion generated from renewables.
The table below shows the EDF Energy Fuel Mix Disclosure for the period 1 April 2016 to 31 March 2017.

Profits of these businesses have been volatile and indeed both companies suffered losses in 2015. This reflects the underlying volatility of the energy business. Nevertheless, the group has such massive asset backing, both in the UK and internationally, that there is negligible financial risk to customers. In the UK alone EDF has assets of over £16 billion.
