Energy Suppliers - Full A-Z list

Energy suppliers play a critical role in delivering electricity and gas to consumers. Understanding the landscape of energy suppliers is essential when making informed decisions about your energy provider.

What happened to the "Big Six" energy suppliers?

Traditionally the UK energy market was dominated by the "Big Six" energy suppliers British Gas, E.ON, EDF Energy, Npower, ScottishPower and SSE. Today only four remain. These are:

• British Gas
• E.ON
• EDF Energy
• ScottishPower

In 2019 E.ON took over Npower as part of the acquisition of Innogy and customers were migrated to E.ON Next in 2020. SSE was taken over by OVO Energy in 2020, taking OVO Energy from a challenger brand to one of the biggest UK suppliers overnight.

Founded in 2015, Octopus Energy has grown rapidly to become one of the UK's largest suppliers through organic growth and increasing its customer base through the Supplier of Last Resort process (where Ofgem appoints a new energy provider to take on customers of a failed supplier). At the end of 2022 Octopus Energy took on 1.5m Bulb customers and is set to take on a further 1.3 million Shell customers by the end of 2023.

Independent Energy Suppliers

Independent energy suppliers, also known as challenger brands, are smaller companies that have entered the market to provide alternative options for consumers. These suppliers offer competitive pricing, innovative tariffs, and often specialize in renewable energy.

By expanding the choices available, independent suppliers have brought increased competition to the energy market and provided customers with more options to consider.

Renewable Energy Suppliers

Renewable energy suppliers focus on providing electricity generated from renewable sources such as wind, solar, hydro, or biomass. These suppliers prioritize sustainability and offer green energy tariffs to environmentally-conscious consumers.

By choosing renewable energy suppliers, customers can actively contribute to reducing their carbon footprint and supporting the transition to a greener and more sustainable energy sector.

Understanding the different types of energy suppliers available allows you to explore a range of options and consider factors such as pricing, customer service, and environmental impact when selecting the right supplier for your energy needs.

Review your current energy contract to understand any terms, termination fees, or notice periods associated with switching suppliers. Make sure you are aware of any obligations or penalties before proceeding with the switch.

3. Contact New Supplier

Once you've chosen a new energy supplier, get in touch with them to initiate the switching process. Provide them with the necessary details and discuss the desired start date for your new contract.

4. Meter Readings

Provide meter readings to both your current and new supplier to ensure accurate billing during the transition. This will help avoid any discrepancies and ensure you are only charged for the energy consumed under each respective supplier.

5. Finalize the Switch

Confirm the switch with your new supplier and ensure that all the necessary paperwork is completed. They will coordinate with your previous supplier to make the transition as smooth as possible.

6. Review and Monitor

After the switch, carefully review your new contract terms, payment details, and any changes to your billing process. Monitor your energy usage and bills to ensure they align with your expectations and address any discrepancies promptly.

Switching energy suppliers can potentially lead to cost savings, better customer service, and access to renewable energy options. However, it's crucial to carefully assess your current contract and consider any fees or obligations associated with the switch. By following these steps and staying informed throughout the process, you can make a successful transition to a new energy supplier that better suits your needs.
