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.
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:
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, 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 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.
In order to assist you in evaluating and comparing energy suppliers, we have curated a comprehensive table featuring every energy supplier available in the UK. This table provides a convenient resource to help you make an informed decision based on your specific requirements and preferences.

Choosing the right energy supplier is an important decision that can impact your energy costs, customer experience, and environmental footprint. When evaluating energy suppliers, consider the following factors:
Review the pricing options offered by different suppliers. Assess whether they provide fixed-rate tariffs, which offer stable pricing over a set period, or variable tariffs, which may fluctuate with market conditions. Compare prices and consider any discounts or incentives available for new customers.
Customer service plays a crucial role in your overall experience with an energy supplier. Research their reputation for responsiveness, availability, and helpfulness. Look for reviews or ratings that reflect their commitment to resolving customer queries and concerns in a timely manner.
