Energy direct debits help

Lower your payments & get money back

Paying by monthly direct debit can cut bills by around £80/yr. Sounds good, and it is! Yet direct debits are based on an estimate of your usage. If that's wrong, you can end up overpaying month after month.

Energy direct debits: the key points

Here are the key need-to-knows about how energy direct debits work.

What you pay isn't necessarily the same as the cost


It's important to be clear the price you're charged and the amount you pay every month aren't the same thing.

  • The price of the energy

    Power costs are set by suppliers. Usually, they're a combination of a daily standing charge plus an additional amount based on energy used, which is measured in kilowatt hours (kWh).

    After all's said and done, this is what your energy actually costs. The lower the rate and the less you use, the less you owe.

  • What you pay

    With a monthly direct debit, the company estimates your annual usage and spreads it over 12 months. In summer, you'll usually build up a credit as you use less, but you'll likely need this surplus for winter.

    But some bills are massively overestimated, where the amount paid seems to have been de-linked from the cost of the energy you actually use. Many customers feel their suppliers set the rate willy-nilly.

    Remember too, even if you're on a fixed tariff, your direct debit can go up if your supplier thinks you'll use more.

Many can save £100s a year by switching (see our free Cheap Energy Club). But when people do switch, bill confusion leaves many thinking they haven't gained. For example, it's possible to move to a cheaper energy company, only to find your direct debit rises. This is because it's estimated wrongly, but you'll get a refund later so you'll still save.

Here's an example...

Beccy Tricity's been with her provider for 10 years and her £80 a month direct debit is set to about the right level. She rightly does a comparison and finds EnergyMonster is 10% cheaper, so she'd expect to pay £72 a month.

However, EnergyMonster sets her direct debit at a mammoth £100 a month. Therefore, for a year, she's overpaying by £30 a month and may be unable to change it. Of course, in the end, she'll get the money back, and will have saved on her unit rate, yet in the meantime, the overpayments mean less cash in her pocket.

The fact that people can end up with a higher direct debit, after switching to what they think is a cheaper supplier, is damaging to the industry. It's a huge disincentive for people to switch, which ultimately stops suppliers winning new business and stops consumers saving cash.

Direct debit is usually cheaper

While there are problems, there's one important fact in favour of setting up a monthly direct debit. It's usually around 8% cheaper than any other way of paying.

If you use heating oil to heat your home, instead of gas or electricity, it's different. Paying by direct debit won't get you a discount. But it can be convenient as it allows you to spread the costs. Heating oil users can learn simple steps to save in our Cheap Heating Oil guide.

Generally speaking, direct debit is the right MoneySaving option (see the Gas & Electricity guide), yet it's crucial you understand how it works before taking it up. For maximum savings, combine it with:

  • Switching to the cheapest tariff and saving £100s. If you've never switched before, savings of £100s/year are possible if you opt for a cheap tariff.

  • Always give meter readings. Give your supplier regular meter readings and it'll give you a more accurate bill. If you don't, you may find you're paying for high estimates.

  • Smart meters. These send meter readings to your supplier automatically, so you should get an accurate bill. They often lose this ability after switching supplier though, so you may need to start doing it manually again. See the Smart Meter guide for more.

Pay too little and you can end up owing your supplier

While this guide focuses on excessive direct debits, the other worry is when they're set too low. This can happen when you use more energy than expected. 

Remember, lowering your direct debit doesn't lower the cost. It just means you'll pay less each month, then get a huge bill at the end of the year which you may not expect and will be chased for. If the debt gets too high, you may not be able to switch.

Ask for a payment plan if you're struggling to pay off debt

If you do find yourself in debt, talk to your supplier as soon as you can. Energy firms are required to help you find a solution. 

If you just ignore the debt, your supplier could contact you about the possibility of installing prepayment meters or even disconnection.

According to the regulator, suppliers must give you the chance to repay the money you owe through a payment plan before installing prepayment meters or disconnecting you – if it doesn't, complain and challenge its decision. 

The payment plan has to factor in both your financial circumstances and your ability to pay. The debt is then repaid over a number of months alongside what you pay for your ongoing energy use.

Energy Fund Schemes

If you have been hit by a huge bill and find yourself in arrears there's help available. Some providers offer an energy fund scheme to help with arrears if you're facing serious financial hardship. 

To apply for help with arrears you'll need to be an account holder – you'll need to complete a full income and expenditure budget sheet along with proof of your income, plus give details on how your arrears have built up, eg, due to illness or redundancy, and say how the grant will help you. It can take several weeks to process your claim.

Exact requirements vary – some say you need to be in receipt of certain benefits for example – but those with the greatest need are prioritised on a case by case basis.

You can apply via these links:

Know your rights

know your rights

After years of persistent complaints, the regulator finally stepped in and introduced new licence conditions setting out guidelines for fair and reasonable direct debits.

Under condition 27 of the Gas Supply Licence, suppliers must:

  • Set fair direct debits. They must take reasonable steps to ensure customers' direct debit levels are based on the best available information, including the quantity of gas and electricity supplied.

  • Give clear explanations. If you ask, your supplier must clearly explain why it's chosen that amount for its direct debit.

  • Refund credits. If a credit has accumulated and a customer asks for it back, suppliers must refund it. If the supplier thinks the credit should be withheld, the reasons why must be clearly explained but customers can challenge this (see how to challenge it).

In theory, this should make it much easier for consumers to get fair direct debits set for them and reclaim refunds where due. As this is a licence condition, energy regulator Ofgem can fine suppliers if they breach it. Many energy companies, including all of the big six, now offer automatic refunds when you're in credit (though the threshold for this happening varies). However, in some cases it'll still be up to consumers to demand a refund.

Annoyingly, Ofgem doesn't set out what's "fair and reasonable". Instead, it leaves it up to the supplier to decide. If you disagree and the company won't sort out your complaint, you can go to the free, independent Energy Ombudsman to dispute it.

Work out why you're paying too much

There are a number of direct debit overpayment scenarios. All need handling slightly differently.

Your supplier's said it's increasing the direct debit

It's possible you've received a letter telling you the direct debit has increased. This may be because your supplier has hiked prices across the board. 

If you think the increase is disproportionate, it's best to deal with that before the new price increase is in place. Do a Cheap Energy Club comparison to see if you can save.

It's put up the direct debit without telling you

Under the Direct Debit Guarantee, the supplier should normally tell you of any changes to your direct debit 10 working days before it's taken out of your account. It might do this by writing to you, or by including a notification on your bill.

If it doesn't, this may be an error. You should complain, ask for compensation, and under the guarantee you can claim the extra cash from your bank.

You switched supplier

switch supplier

Outrageously, some who have switched to a supplier that's supposed to be cheaper find their direct debit set at a higher level, which is counter-logical. Your new energy firm will often justify this by saying it doesn't yet know your usage, so it's gone higher to make sure usage is well covered.

Here, the best thing is to arm yourself with knowledge of your past usage. Check how much in credit you were in with your last supplier too, before calling to attempt to rearrange the debit.

The current direct debit is too high

There are many scenarios where this may have happened. Maybe your house is more energy-efficient than it used to be, or you've been overcharged for a long time without noticing. Or maybe you've been paid back a substantial credit amount over the last year, but the supplier's not lowered the amount it demanded.

The obvious evidence here is being substantially in credit.

How to fight back

While there are guidelines suppliers must adhere to – and many are now offering automatic refunds – you could often still have a fight on your hands to get your cash back. After all, while the companies have your money, they can earn stacks of interest.

Plus, for many years, some firms operated a 'don't ask, don't get' policy, so it could be worth checking if you're also owed credit from any old suppliers – see Energy Credit help for more. 

Here's how to make sure you get what you're owed:

Step 1: Always do a meter reading

meter reading

Don't let the company rely on its estimates, that's just a great excuse to set high direct debits. Keep it as accurate as possible. The info on how to read your meter will be on the back of your bill, or look online. Usually you can give readings online, or by calling an automated answer system – or sometimes you can even call up and speak to an actual person!

If you've never given a meter reading before and have been relying on estimates, then do the reading and wait for the updated bill before even attempting to ask to have the debit lowered.

Step 2: Ask for your money back

money back

In itself, being in credit on your bill doesn't mean the energy company is doing anything wrong. Energy usage is seasonal, so it's expected that between summer and winter, you may have racked up some credit.

Yet if you're heavily and disproportionately in credit, then before even beginning to talk about lowering the direct debit, try to get a chunk of the amount you've overpaid back. According to Ofgem, suppliers must refund an accumulated credit, though it doesn't say what it thinks is fair.

As the table below shows, many energy companies have payout policies, and the majority, now issue refunds automatically each year on the anniversary of when you signed up to their tariff (though the threshold for getting a refund varies).

That said, you may still have to chase. If you think you're owed, call and ask for your cash back. Quote condition 27 of the Gas Supply Licence, which states credits must be refunded and direct debits fair. If it won't reset it, you're entitled to a full explanation, and you can complain to the Ombudsman. 

Providers' refund policies (correct at October 2019)

British Gas If you're in credit by more than £75, you'll need to contact it to get a refund. It'll only refund anything over £75, and puts the rest toward your future bills.
E.on If your account is more than £5, it'll refund you automatically as long as you've submitted a meter reading in the last six months.
Npower If you've built up a credit of £25 or more, it'll refund it automatically, providing your latest statement is based on an actual and not estimated meter reading.
Scottish Power If you're in credit by more than one month's payment value or by over £75, you'll get an automatic refund. If you're in credit by less than this, Scottish Power says you can still request a refund if you provide up-to-date meter readings.
EDF Provided it has an up-to-date meter reading, EDF will automatically refund you any in-credit amount above £40.
SSE Gives automatic refunds on in-credit cash of more than £60 provided your last bill was based on an actual and not estimated meter reading.
(1) Paid on the 12 month anniversary of when you signed up to the tariff.

Step 3: Call to ask for a lower direct debit

call now

You have a right to ask for an explanation of why your direct debit is set at a certain level, so call up and do it. If you're always in credit and it isn't just seasonal, politely request the direct debit be lowered to reflect your ACTUAL annual usage and meter readings.

It's possible you may have a small debt on the account too. In this case, paying off a £20 debit balance to bring the account to zero is likely to give you more leverage when renegotiating the direct debit. Customer service staff may sometimes be limited in what they can do due to their computer systems, but paying off the debt may give them leeway.

Do remember electricity and gas companies rightly should err very slightly on the side of overpayment rather than underpayment, as otherwise you could get a shock at the end of the year with a big catch-up bill. If you're unsuccessful, see the next step.

Step 4: Formally request the direct debit's lowered

At this point, you've gone through the usual protocols, and it's here where you have to make it not worth the energy company's time to continue making you overpay.

Writing a formal letter indicates you're taking it seriously and you're unwilling to let it lie. Write to say your direct debit is set too high, it breaks the energy retailers' code, and threaten if there's no change, you'll ditch and switch.
