EDF Business Energy Profile: Tariffs & Reviews

EDF is a member of the big 6 and the UK’s largest producer of low carbon electricity. They have approximately 5.7 million customers and serve over 200,000 businesses, ranging from micro businesses to SMEs and large businesses.  

The company was founded in 2002 and is a subsidiary of Electricité de France, a French state-owned company. In 2009, EDF purchased share capital in British Energy, the nuclear generator. They are now one of the largest producers of electricity, and one of the largest distribution network operators in GB. 

EDF is unique in that it offers renewable and ‘low carbon’ tariffs, with their low carbon tariffs utilising electricity from nuclear power. This is the result of them owning the UK’s largest network of nuclear power stations

Key features:

  • Low carbon nuclear tariffs 
  • 100% renewable tariffs
  • Fixed and flexible (variable) 
  • Fixed tariffs up to 4 years
  • Smart metres for SMEs

EDF Energy Core Services 

EDF serves non-domestic customers throughout the UK with a focus on gas and electricity for SMEs. They also serve large businesses. They offer fixed and flexible (variable) tariffs as well as ‘low carbon’ and renewable tariffs.

The products they offer differ for SMEs and large businesses with large businesses enjoying the lower rates by far. Uniquely, however, SMEs and large businesses can both choose from a fixed or flexible price contract. Most suppliers only allow large businesses to jump on fixed contracts, because they want to tie them in. 

In addition to gas and electricity, EDF also offer:

  • Smart meters
  • New installations
  • EV charging points 
  • Energy efficiency business energy products

EDF Energy Business Electricity and Gas: Tariffs & Rates

EDF Energy offers a variety of business energy tariffs:

Fixed for Business Tariffs

EDF’s Fixed for Business Tariffs let you fix the price of energy for 1, 2, 3 or 4 years at a time with a 7% discount when paying by Direct Debit. You can take out gas, electricity or dual fuel with this tariff with a fixed price on both. 

  • Fix for up to 4 years
  • 7% discount if paying by direct debit

Freedom for Business Tariffs

EDF’s Freedom for Business Tariffs are variable gas and electricity tariffs with prices that go up and down with the market. The benefit is you can opt out at any time with no exit fees, so this may suit your business if you need temporary energy. 

  • No exit fees
  • Upgrade to a fixed plan at any time

Flexible contract (large businesses)

EDF’s flexible contract lets you buy blocks of energy – and you can choose how far into the future you want to buy them. This is a solution for large businesses whose energy demands outstrip what a standard tariff can supply. 

  • Purchase energy blocks in bulk
  • Suitable for the largest businesses 
  • Buy energy from 1-3 years, 3-5 years, or 5+ years


EDF Energy Deemed Rates 

You will pay deemed rates if you move into premises with an existing EDF energy supply, or if your contract expires without renewing. Deemed rates are more expensive than contract rates, so you should switch as soon as possible. 

  • Half-hourly deemed rates for large businesses can be found here
  • Non half-hourly deemed rates for large businesses can be found here.
  • Deemed rates for micro, small and medium-sized businesses can be found here.

The deemed rate links provided were accurate and relevant as of 28.05.2020. 

EDF Energy Fuel Mix 

EDF offers businesses a few different types of energy tariffs depending on their size and consumption needs. Their standard tariffs are mostly fuelled by nuclear power, and they also offer a low carbon tariff with 100% nuclear electricity. 

Their standard fuel mix is as follows:

  • Coal 5.20%
  • Natural gas 10.84%
  • Nuclear 72.07%
  • Renewable 11.73%
  • Other 0.16%

And the environmental impact is as follows:

  • CO2 emissions – 87g per kWh
  • Radioactive waste – 00.50g per kWh

The low CO2 emission output compared to other energy suppliers who also have a mixed fuel mix is because EDF sources the bulk of their energy from nuclear (this is why they also have higher than average radioactive waste). 

Their low carbon tariffs use 100% nuclear power and have a radioactive waste rating of 0.0060g per kWh. EDF also offers renewable tariffs to eligible small businesses, which offer no CO2 emissions or radioactive waste.

EDF Energy Reviews

EDF Energy is rated excellent with customers online – although it depends which review platform you look at. 

Here’s a breakdown of their ratings across different review platforms:

  • Trustpilot – they have a 4.5/5 star rating based on over 8,500 reviews
  • Review Centre– they have a 1.4/5 star rating based on over 250 reviews


EDF Energy has also been compared to other suppliers for complaints handling:

  • Citizens Advice – EDF Energy Ranked 4th out of 16 for complaints handling among non-domestic energy suppliers.


How these ratings compare 

EDF’s Trustpilot rating is better than all other members of the big 6 (British Gas, Scottish Power, SSE, E.ON, Npower) and they also rank better than many smaller suppliers. However, their Review Centre rating is less favourable. 

If we combine the review rating systems of Trustpilot and Review Centre to give us an overall score out of 10, EDF Energy gets a 5.9/10 rating. However, Trustpilot’s reviews are in a far greater number, so the 4.5/5 rating is a good metric. 

In terms of complaints handling, EDF was ranked by Citizens Advice in 4th place out of 16, ahead of Utility Warehouse, Total Gas & Power and Opus Energy, but below Contract Natural Gas in third, SSE in second and E.ON in first.
