Maximise your Avios, air miles and hotel points

Which energy suppliers let you pay your bill with an American Express card?

Links on Head for Points may pay us an affiliate commission. A list of partners is here.

Gas and electricity is a substantial monthly outlay for most people, but it is rare that you find a way of putting the cost of gas and electricity onto an American Express card.

This is unfortunate, as it would make a major dint into the spend you need to trigger a sign-up bonus or your annual British Airways American Express 2-4-1 companion voucher.

There IS a way to pay via credit card, however, and it works with many of the newer suppliers. You are unlikely to get very far with any of the legacy utility companies, unfortunately.

How to pay your energy bill with an American Express card

Whilst most energy suppliers will prefer to set up a monthly or quarterly direct debit to keep costs down, many will let you top-up your account at any time.

This can often be done using an American Express (or other credit) card.

Doing a top-up does NOT mean that your next Direct Debit payment is not taken.  Energy companies will try to charge you a flat monthly figure throughout the year even though your usage is higher in Winter. This means you build up a balance during the Summer and it unwinds during the Winter.  Making a top up payment simply increases this balance.

Some suppliers do, however, let you reduce your monthly direct debit, although it may depend on how much of a buffer you have in your account.

Your money should be safe if you do top-up.   Whilst a lot of small energy companies have gone bust in recent years, Ofgem has a system in place to ensure whoever takes over your account honours outstanding credit balances.  If this failed – which seems unlikely – you would still have protection via your payment card.

Pay Bulb with american express

Using American Express with Bulb

Rob has used Bulb for a couple of years for his gas and electricity.

Bulb operates differently to most companies, having only one tariff. There is no ‘introductory’ rate or other deals – everyone gets the same price, and that price is fixed at a small margin above the wholesale rate. Whilst an introductory deal from another company may be cheaper in the short term, Bulb works fine for anyone who wants to switch once and then not think about it for five years, confident that the deal will always be ‘market’.

If you are concerned about your environmental impact,  100% of Bulb’s electricity is renewable and their gas supply is 100% carbon neutral.

To top up your Bulb account with an American Express card, head to your ‘Payments & Statements’ page on their website. You will see:

If you click the ‘Top up’ box, you get taken to the payments processor Stripe:

…. and you can see American Express as a payment option.  It works fine – Rob has done it.

Even better, when Rob moved house last year and closed his Bulb account (and then opened a new one at his new property), the credit balance on his account was paid out in cash to his bank …..

Bulb has a £50 refer a friend sign-up bonus if you sign up for electricity and gas or £25 for one fuel.  Rob’s wifes refer a friend link is here.

Using American Express with Octopus Energy

Octopus Energy is another supplier that will let you top up your account with an American Express card, as Rhys has found.

To top-up your account, click on ‘Make a one-off payment’ in your account:

Octopus Energy pay Amex card

Once done you are taken to a payment page. As you can see, inputting the first four digits of your Amex card show that it is working:

Octopus Energy Amex card payment

You can reduce your direct debit to as low as £1 per month in your online account to avoid overpaying.

Like Bulb, Octopus supplies 100% renewable electricity and also offers a £50 refer a friend sign-up bonus when you sign up via this link. This also applies for London Power, which piggybacks on Octopus Energy.

You can also sign up via the Virgin Red app, which offers you 7,400 Virgin Points for a dual fuel switch and 3,700 Virgin Points for a single fuel.

If you are not a Virgin Red member, you will need to register – free – here.

This works for other providers too

According to recent comments on HfP, a number of other energy suppliers let you pay via American Express. No-one on the HfP team has any experience of these suppliers, however.

These include:

  • Igloo
  • Avro
  • People’s Energy
  • Outfox the Market
  • Green

These are smaller players in the energy market but, as mentioned above, you should be protected in case the company goes bust by both Ofgem and your payment card under Section 75 coverage.

Please do leave a comment below with your experiences of these companies – I’m sure this would be appreciated by other readers. We will update the list above during the day with any additional reader suggestions.

    Moved to Green and they have been very good. Price fluctuates since on variable rate but with no exit fees and cheapest for us, they have been good. Customer services chat via app works well and top up with Amex is a bonus. They even had a 10% bonus for topping up last year which worked well.

    • Steve says:

      Will Green let you reduce the DD amount based on the top up, or do you need to use the low usage “trick”?

      • Doc says:

        Steve, haven’t tried to reduce DD yet since other half working from home and so our DD is spot on even with the extra payments I have done. So not 100% sure.

  • JP says:

    M&S Energy, which is also a white label version of Octopus also accepts Amex for top ups and allows a variable direct debit so will adjust for the payments you have made and not take additional ones.

  • mark2 says:

    Some suppliers pay interest on credit balances up to a limit.
    Ovo used to pay 3%up to £1000; may still do so.

    • Alan says:

      Igloo do this too.

    • Harrier25 says:

      OVO still pays interest on the first £1,000 at 3% in year 1 followed by 4% in year 2 and than 5% in year 3 and thereafter. You can top up your account but only with Visa and MasterCard.

    • Julian says:

      I can’t believe its 3% now or otherwise people might try putting £10,000 extra credit with them……………….

  • LeMain says:

    Ecotricity, as well as offering 100% renewable electricity, allow bills to be paid by Amex at no additional cost.

  • Melvin says:

    I use Avro and choose to pay £100 by Amex only last week, as a test. The payment went through fine. I have messaged them since and asked if my direct debit could be reduced to allow me to pay by card, but unfortunately they kinda dodged the question. Their terms say they will review the DD every three months so overpaying might work. Not sure that’s where I want to go though.

    • Peter K says:

      I overpaid Avro by £700 and asked for a DD reduction. No was basically the answer.

  • Jeff says:

    I have just successfully used Amex with Green ,,, thanks for the tip

  • Lol says:

    Igloo pay 3 per cent interest on the account balance. I transferred to Igloo in January and set the Direct Debit at £10 per month and topped up the account by a £1000 using Amex. I’ll do a similar top up towards the end of the year.

    Igloo gas and electric costs compared well at the time with a couple of other companies and I’ve found the Igloo website is easy to use and their admin efficient.

    • Lol says:

      You can also get £50 credit with Igloo if you transfer to them using a referral code. If you ask for a code here I’m sure a few HfP readers will offer you the referral link!

    • Steve says:

      When you say you set the DD to £10 per month, is that an option because of your overpayment or due to setting the usage so low as to be £10 worth?

  • Nick M says:

    I’m with Igloo, and very happy with them. Obviously check on MSE etc as to who is cheapest for your circumstances….

    I have a referral code I’ll be happy to share with anyone!

    • John Gallagher says:

      Igloo accepts Amex and also Apple Pay

      • Julian says:

        Like Igloo as a concept as they only have one variable tariff and no fixed tariff for all their customers so that variable tariff is bound to be fair and competitive or they wouldn’t get any new customers.

        However Bulb seems to be more or less the same but have both Pay Monthly and Pay As You Go options. Pay As You Go is only possibly if you have Smart Meters as far as I can tell. Just had Honeywell (formerly Elster) SMETS2 smart gas and electricity meters installed last week and mobile signal is fine sending back the readings from the basement room.

        Main snag is the In Home Display (IHD) does not work due to my flat’s distance from the meter room (not very much but its a floor down a couple of doors away) and may take a few more months yet for a suitable connecting device from the http://www.althanco.com to become available to fix this problem.
