Energy suppliers: how many are there, and who’s the best?

According to the energy watchdog Ofgem there are a whopping 57 active energy suppliers across the UK.

How many UK energy suppliers are there?

Some of these, however, are subsidiaries of larger companies and groups. OVO Energy, most notably, owns a number of energy suppliers in the UK including Spark Energy, Boost and (its biggest and most recent acquisition) SSE. It is important to thoroughly compare energy suppliers.

What’s the difference between energy suppliers in the UK?

In terms of the energy they provide, absolutely nothing. All the UK’s suppliers distribute the same gas and electricity through the same networks of wires and pipes. But that doesn’t mean that all suppliers in the UK are the same. The difference lies in a number of factors. Of course, pricing plays a vital part in setting one apart from the other. But there are also other considerations like customer service, and how well they respond to a crisis or loss of supply.

The “Big 6”: Who are the Top 6 energy suppliers?

While there are 60 active suppliers in the UK, the lion’s share of the energy market is provided by the “Big 6” energy suppliers. Between them, these 6 companies supply 70% of the electricity supply and 69% of the gas supply in Great Britain.

The “Big 6” energy suppliers are (in no particular order):

British Gas
SSE
E.ON Energy
EDF Energy
nPower
Scottish Power

But, as any savvy consumer will tell you, bigger doesn’t necessarily mean better.

But really…

Who are the best energy suppliers in the UK?

One good thing about the vast number of energy suppliers in the UK today is that the increased competition can prove beneficial to consumers. There is a long list of energy suppliers in the UK. As suppliers scramble to engage new customers, they’re all trying to out-perform one another by presenting attractive new tariffs for consumers.

This means that savvy customers can use comparison services (like us) to trawl through dozens of tariffs to help you find the best one for your needs. But while the right tariff is important, it’s also important to choose the right supplier.

Who has the best customer service?

Smaller energy companies often burst onto the market with offers and tariffs that are too good to miss. The trouble is that sometimes they go bust very quickly. Others do very well for a short time then disappear almost overnight. As such, many people gravitate towards the “Big 6” because they are perceived as more reliable. They may get bought out or subsumed by another supplier or group… but you don’t have to worry about them going bust overnight.

However, according to consumer ratings in 2020, the “Big 6” providers were among the lowest rated for customer service. The highest rated were as follows:

• Octopus Energy
• Bulb
• Ecotricity
• Good Energy
• OVO Energy

Who are the cheapest energy suppliers in the UK?

One supplier’s energy is completely indistinguishable from other’s. So, why pay more for it? When choosing an Energy Supplier, it’s likely that low prices and great value for money are high priorities for you.

So, let’s find out who the cheapest Energy Suppliers in the UK really are.

While costs may vary depending on your usage and the region where you live, these are the 5 providers with the cheapest tariffs on the market today:

• Green Energy
• Outfox The Market
• So Energy
• Octopus Energy
• Robin Hood Energy

All of the above offer tariffs at costs significantly below the energy price cap of £1,126 per annum with savings of around £200-£300 pounds.

Who is the greenest supplier?

Consumers are growing increasingly conscious of the ecological impact of their choices on the planet we all share. As such, when choosing a supplier, they want to ensure that their energy mix is as renewable as possible. Fortunately, this is something that energy suppliers are growing increasingly conscious of, with many generating their own energy as well as supplying it. Scottish Power and SSE are two good examples of this, generating significant energy from their on and offshore wind farming infrastructures.

However, you may be surprised that even the efforts of the “Big 6” pale in comparison to these smaller companies that have a strong focus on renewable energy. All of the following offer 100% renewable electricity as well as carbon neutral or renewable gas:

• Bulb
• Green Energy
• Ecotricity
• Good Energy
• Tonik Energy

Business energy: who is the best business electricity supplier?

Most energy suppliers offer not only domestic tariffs but special commercial tariffs for businesses. While the “Big 6” tend to dominate in the world of commercial electricity, there are still a number of smaller energy suppliers in the UK with commercial electricity tariffs.

Bulb, Corona Energy, Robin Hood Energy, So Energy and Ecotricity all have competitively priced tariffs targeted at business users. On balance, Bulb is probably the best business electricity supplier with a good combination of affordability, renewability and customer service.
