E.ON started out life in 1989 as Powergen, and was acquired by German utility company E.ON in 2002, before officially rebranding as E.ON UK in 2004. Today, E.ON is praised for being a leader in the shift towards sustainably-sourced energy.

What E.ON tariffs are available?

E.ON offers a good range of tariffs to suit any UK household. At the time of writing, these tariffs include both fixed and variable options, as well as prepayment and variable plans (information correct as of November 2020):

E.ON electric vehicles

E.ON’s Fix and Drive plan is exclusively for those who own or lease a plug-in electric or hybrid vehicle that’s been registered with the DVLA. It currently offers 12 months of fixed rate energy with an exit fee of £60. For each year you’re on the plan you’ll receive a reward of 850 miles (equivalent to £30), which is credited to your account six months into your contract each year. 

This is a dual-fuel tariff and it can only be paid for using direct debit. Under this plan, E.ON will match 100% of your energy with Renewable Energy Guarantees of Origin (REGOs) and 100% of your gas with Certified Emission Reduction Certificates (CERs). 

Renewable electricity with E.ON Energy

E.ON Energy now offers 100% renewable electricity with all its tariffs. This means you can be sure you’re receiving electricity that’s backed by 100% renewable sources, regardless of which tariff you choose. This includes electricity sourced from wind, solar, and biomass. 

Currently, energy sourced by E.ON from its renewable assets and renewable supply agreements provides enough electricity to power 1.7 million homes, based on the consumption of the average E.ON customer. This covers 61% of E.ON’s domestic and small business customer base, and 46.3% of its entire customer base when corporate customers are also included. To make up the shortfall, E.ON purchases renewable electricity guarantees certificates as well as power from independent wind power generators in the UK.

E.ON green energy

E.ON has invested over £9 billion in UK renewables since 2007, and has been a frontrunner of the energy industry in pushing forward more sustainable practices and promoting fuel efficiency. Its current fuel mix (for electricity and Renewable energy is just one way E.ON is working to achieve these goals, but its efforts can also be seen through other services like its electric vehicle deals, smart meter and smart thermostat rollouts, and its solar panel plans.  

E.ON’s priority of helping green energy sources outperform unsustainable fossil generators has helped the provider maintain and grow its popularity in recent years. 

E.ON smart meters

Along with all major energy suppliers, E.ON Energy is helping both business and domestic customers receive a more accurate picture of their energy use by rolling out smart meters across the country for no charge. E.ON claims that using smart meters will support the shift towards a carbon-neutral Britain, helping households become more energy efficient.

Although the UK government postponed the deadline for the rollout to June 2021, E.ON is one of the few companies that has made smart meter installation mandatory for all its fixed-price tariffs where eligible.

Smart meters automatically send regular readings to your energy provider to save you the hassle of doing so manually. They also ensure you receive accurate bills based on your actual usage rather than an estimate.

Along with your smart meter, you’ll also receive an in-home display that you can use to track your energy consumption with real-time, personalised insights. You’ll be able to set a daily budget, view your CO2 emissions, view and compare your gas and electric usage history, and more. Prepayment customers on the Smart Pay As You Go tariff can also use the in-home display to top up credit and activate emergency credit. 

How does a smart meter help reduce energy costs?

Your in-home display is handheld, so you can even take it around the house and, as you turn on and off appliances, view how much energy each appliance is using at the time. This helps you gain an accurate picture of your energy usage, enabling you to identify areas where you’re consuming too much energy unnecessarily. From here you can adjust your habits and watch your consumption (and bills) drop.

In receiving more accurate data about consumption nationwide, energy providers are also able to monitor energy production and supply more precisely, enabling them to plan accordingly and further reduce waste. E.ON claims that if every UK household were to switch to a smart meter, the impact would be the equivalent of planting 75 million trees every year. E.ON also offers discounts on a number of additional smart home technology products, including smart lighting and thermostats.
