British Gas vs E.ON Next (2024 Comparison)

Last updated: 19th January 2024

Energy supplier giants British Gas and E.ON Next are comparatively popular. But, how do they compare value for money and customer reviews? In this guide, we take a look at how the two energy names compare on what matters most to consumers. If you are looking for a comprehensive energy supplier comparison, you’re in the right place!

Who is E.ON NEXT?

E.ON Next is a brand of E.ON that was founded after the collapse of Npower in 2019. The energy company was launched separately from E.ON and found its way into the market by solely focusing on sustainable energy. Despite sharing the same name, E.ON and E.ON Next are different. E.ON Next has its own tariffs and contact details.

Who is British Gas?

British Gas is one of the country’s largest energy suppliers. They were founded in 1812 and are known for supplying customers with natural gas and electricity. British Gas has grown its services from its initiation. Today the brand offers a wide range of energy-related services spanning boiler installation and maintenance, central heating, smart home solutions and more.

What’s the difference in tariff options?

Both E.ON NEXT and British Gas offer three ‘standard’ tariffs to their customers. However, all of E.ON NEXT’s tariffs come with 100% renewable electricity, great for those who want to live a more green lifestyle.


E.ON NEXT offer three different energy tariffs to customers, two fixed-term options and one that is variable. All of the tariffs include 100% renewable electricity and E.ON NEXT can also provide energy to businesses too.

NEXT Fixed Tariff (12 or 24 months)

– Discount applied if you pay by direct debit.
Fixed tariff for 12 or 24 months meaning fixed and predictable prices
– An exit fee of £75 for a 12-month contract and £150 for 24-months
– Smart meter required
– 100% renewable electricity


– Variable prices, so prices can go up and down over time.
– No contract, so no exit fees.
– Discount applied if you pay with direct debit.
– 100% renewable electricity

For those on a variable tariff, no exit fees are charged as no contract is in place.

Both E.ON NEXT’s variable and fixed-rate tariffs can be either charged on a single rate or off-peak basis. For an off-peak tariff, customers will need to have the right meter installed. This could be an economy 7 meter, for example.

E.ON NEXT also offers either electricity or gas-only tariffs. For customers who require just one type of energy rather than a duel-fuel tariff, this is an excellent option.

British Gas

British Gas offers customers three types of tariff, much like E.ON NEXT. The tariffs include two fixed-term options and a variable tariff for customers who don’t want to be locked in with a contract. All of British Gas’ tariffs are matched 100% with renewable energy. Let’s take a look at these tariffs in more detail.

Fixed Energy Tariff (The Fixed One v25)

– A fixed tariff rate for 12 months
– If energy prices increase, the tariff price stays the same
– £100 exit fees per fuel
– Optional sign-up for PeakSave, a scheme that rewards customers for mindful energy usage
Ofgem caps don’t apply

Standard Variable Tariff (Standard Variable Tariff v14)

– This is a tariff available to customers who pay via direct debit.
– There is no end date for this type of tariff and you can leave whenever you wish to with no exit fees.
– Variable tariffs go up and down and customers will be provided with notice before any price changes.
– Customers on this tariff can also choose to sign-up for PeakSave, a scheme that rewards customers for mindful energy usage.
– Ofgem caps apply to this tariff.

Safeguard PAYG

– Pay as You Go rates match direct debit prices.
– There are no exit fees and no end date.
– Variable tariffs go up and down and customers will be provided with notice before any price changes.
– Ofgem caps apply to this tariff.
Conclusion: From the information we’ve gathered, it’s clear that both energy suppliers offer customers a great range of energy tariff options. However, E.ON NEXT offers its customers better discounts when they set up direct debits which means greater savings all around.

Who offers the greenest energy?

British Gas and E.ON NEXT are both regarded as highly green energy companies. In fact, they are two of the best-known renewable electricity and gas suppliers in the U.K.

All of British Gas’ fixed tariffs are matched 100% with renewable electricity meaning that customers are one step closer to net zero. The Green Future Tariff from British Gas helps customers to go that one step extra to a greener lifestyle.

100% of your CO2 footprint from your gas use will be balanced by carbon-cutting projects around the world (90%), and renewable biogas made from food and farm waste (10%) and you’ll also protect five trees in the UK per fuel for each year of your green energy tariff, contributing to cleaner air and improving natural habitats (source).

Moreover, the British Gas’ Green Future Energy Tariff has been awarded the gold standard by Uswitch – one of the only three energy suppliers to achieve this accreditation.

E.ON NEXT is a 100% renewable electricity supplier meaning that all customers, irrespective of whether they are a home or business, benefit.

E.ON NEXT generates its own renewable electricity with biomass plants in Lockerbie and Sheffield. It creates enough renewable energy to power 100,000 homes throughout the UK. E.ON NEXT also works with other renewable generators such as wind farms and they buy REGO certificates (source).

Conclusion: It’s clear that both of these energy suppliers commit to providing green gas and electricity. However, British Gas seems to go the extra mile when it comes to pledging to be green!

Hi, I'm Rob and I run I initially started this project 5 years ago when I was looking to switch energy suppliers and found there wasn't a website that provided simple, data backed reviews on all the suppliers available. Since then, I spent have a lot of time (too much some may say!) looking at all publicly available data about each supplier and writing reviews using this information. These reviews are updated as regularly as possible and any data is backed up by a source where necessary. I have also started writing guides on various energy related topics which hopefully you will find useful. If you find any issues, please use our contact form to let us know.
