Are you an existing ENGIE customer?

If you’re an existing customer, you might be wondering how things have changed since your ENGIE account was bought by Octopus Energy. Keep reading to find the answers to some of your questions.

ENGIE login

When ENGIE was bought by Octopus Energy, you should have received a letter inviting you to sign up for a new account. Octopus Energy will manage your online account, which is great news for you as there are a lot more features available.

Through your online account, you can:

  • Send meter readings (and win prizes when you do)
  • Update your details
  • Change your payment methods
  • Monitor your energy usage
  • Request a smart meter
  • Contact customer services
  • View and download your bills
Log in to your account

Why can’t I access my ENGIE account?

If you’re having trouble with your ENGIE login, it may be because you haven’t set up your new Octopus Energy online account. While you should have received a letter inviting you to do this, you might not have actually done it yet.

Create an account

If you’ve definitely signed up for a new account, make sure you’re using the right email address and password. Check your spellings and make sure the combination is the right one for your Octopus account. If you’re still having trouble, after resetting your password, you can email or call 0808 164 1088.

Making payments and topping up

If you have a prepayment meter, you might have more questions about topping up than anything else, especially now you’re with a new provider.

You can now top up your prepayment meter at:

Just take your electricity key or gas card to your local outlet and they can top them up.

How do I get a new top-up key or card?

If you’ve lost or damaged your top-up key or card, you can easily get a replacement. Just bear in mind that you might have to pay for it.

All you have to do for a new one is email or call 0808 164 1088.

If you can pick up a new key or card from your local PayPoint, you’ll be given a code when you call or email to take to a PayPoint outlet where they’ll use it to issue your new key or card. You’ll have to put the new key/card in your meter to activate it before you can top up.

Alternatively, you can have your replacement sent in the post, but this might take a few days.

What if I can’t top up?

If you’re struggling, each of your meters will hold emergency credit for you to use when you’re running low. Bear in mind that any emergency credit used will be taken out of your next top-up.

Your electricity meter holds £5 of emergency credit which you can activate when your credit falls to less than £1. To activate this, you just have to put your key back in the meter and press ‘A’.

Your gas meter holds a different amount of emergency credit depending on the time of year. Between April and October, your meter will hold £5, however, between November and March, your meter will hold £10 of emergency credit. This can be activated by reinserting your card into the meter and pressing ‘A’.

If you think you’re going to struggle to pay your bills in the long term, you can call 0808 164 1088. You might be able to set up a payment plan or talk about other options.

I want a smart meter

Automatic meter readings!

Did you know that with a smart meter you’ll never have to submit a meter reading again! 100% accurate bills, all the time. Give us a call to find out more about automatic meter readings.

Smart meters are being rolled out across the country at an extremely fast pace. Providers are offering them to all of their customers and are mostly being installed area-by-area. But why are they such a great piece of tech?

  • They’re free to install
  • They can send meter readings automatically
  • They can save you energy
  • There are smart meter exclusive tariffs to save you money
  • You can monitor and understand your energy usage more easily

Why is my ENGIE smart meter beeping?

Smart meters beeping can be a common occurrence, but why is it doing it and how can you make it stop? There are a few reasons your smart meter might be beeping.

If you’ve set a budget on your smart meter, your in-home display might be beeping because you’re getting close to or over your budget. This could also be the case if you haven’t set one as many smart meters come with preset budgets. To stop it from beeping so much, you can try changing the budget through your in-home display or by cutting back on your energy usage so you aren’t reaching the limit!

Another reason it might be beeping is that your in-home display is running out of battery. This is easy to fix and prevent as all you have to do is plug it back into the wall and charge it. Watch where you plug it in, as it may start beeping again if it loses connection with the meter.

Are you considering switching to ENGIE?

Unfortunately, you can no longer switch your home energy to ENGIE as their residential accounts were bought by Octopus Energy. However, that doesn’t stop you from switching to Octopus. Visit our guide to find out more about Octopus Energy.

Fuel Mix

ENGIE and Octopus Energy are both very conscious about the road to net zero so it’s no wonder they were happy to work together. They’re now a 100% renewable energy company, which we can break down even more into:

Apply for the Warm Home Discount

Octopus Energy offers the Warm Home Discount to all of its eligible customers and the customers of other energy companies it works with. If you’re eligible, you could receive a one-off payment of £140 to go towards your winter energy bills from September to March.

Get £140 from the Warm Home Discount

Let us guide you through the Warm Home Discount and find you the right tariff that can also give you an additional £140 from the Warm Home Discount.

If you’re eligible, you’ll be placed in one of two groups:

  • The core group – To be in the core group, you’ll be receiving the Guarantee Credit element of Pension Credit. If you’re in the core group, you’ll be signed up for the discount automatically and will receive a letter from the Department of Work and Pensions letting you know and if there’s anything else you need to do (there shouldn’t be).
  • The broader group – If you receive certain benefits and support, you could be eligible for the broader group. The criteria for this group can vary by provider and you’ll have to apply for the discount every year. Unlike the core group, there is only a limited number of discounts available for this group, so they’re given on a first-come, first-served basis.
