Your EON login page will be different depending on whether you're a residential or business customer. If you're a homeowner with a boiler, it’ll be different compared to those with a Heat Interface Unit. Business customers will log in another away compared to corporate customers. With so many login pages, where do you start? Here we'll guide you step-by-step.

EON login for residential customers

With EON, homeowners can have their water heated either by a boiler or by a Heat Interface Unit (HIU). The latter is an example of how EON uses its energy portfolio to generate renewable energy. See the supplier’s full energy portfolio in our leading EON guide by clicking the button below:

Does this apply to me? If you have a boiler installed at home that heats your water, you'll be receiving separate gas and electricity supplies from EON. You can identify the name of your tariff in our EON tariffs guide.

Customers with a Heat Interface Unit (HIU)

You probably won't know what an HIU is unless you already have one. Let's go over what it is and how you'll access your EON login page as a "Heat customer".

What is EON Heat?

It's a different way of getting heating and electricity rather than using a traditional boiler. According to EON's marketing material, its Heat customers will have a Heat Interface Unit (HIU) instead of a boiler, which is about the same size.

If you're an EON Heat customer, you won't be on any of their plans listed on our EON tariffs page (link above). Your best bet is to reach out to EON directly for any login or billing issues.

    2. Type in the account number of the second account and click ‘Register'.
    3. Go to ‘Your Account', and choose which account you want to view.

    4. From the application listed, open a menu displaying additional applications and locate the most recent version of Adobe Reader.
