How do you pay a business energy bill?

How you pay your business energy bill affects more than convenience. It can affect the rate you are offered in the first place, and it changes what happens if a payment ever goes wrong or goes missing.

What payment methods are available?

Most suppliers offer a mix of the following, though the exact list varies:

• Direct debit, either fixed monthly or variable to match usage
• Standing order, where you control the amount and date rather than the supplier
• Bank transfer (BACS), paying a bill manually each time
• Card payment, often through an online account portal
• Cheque, still accepted by some suppliers for account or bill payments

British Gas Business, for example, says customers can pay online or set up a regular direct debit, and directs those who cannot pay by direct debit to the back of their bill for the full range of payment options for their account type. EDF tells its large business customers that the easiest way to pay is by direct debit, arranged using a downloadable mandate form. Not every method is available with every supplier, and some restrict your choice depending on your contract type or credit assessment.

Why is direct debit usually the cheapest option?

Because it gives the supplier the most certainty that it will be paid, on time, every time. Ofgem’s best practice guidance on non-domestic security deposits notes that a supplier’s assessment of your credit risk takes into account factors like billing frequency, since the more predictable your payment pattern, the less exposure the supplier carries between bills. Direct debit is about as predictable as payment gets: the money leaves your account automatically on an agreed date, without you or the supplier needing to do anything each time.

This is also connected to the credit assessment covered in our guide to business energy credit checks and deposits. A supplier that sees lower risk from your payment method has less reason to build a margin, a deposit, or restricted terms into your contract. Choosing a less certain payment method, such as paying by cheque or bank transfer whenever a bill happens to arrive, does not automatically cost you more, but it removes one of the factors that can help you get a better deal in the first place.

Fixed or variable direct debit: what is the difference?

British Gas Business offers both, and the distinction is a useful one to understand whichever supplier you are with:

Type	How it works	Best suited to
Fixed direct debit	You pay the same amount on the same day each month, calculated from recent usage and any outstanding balance spread across the year	Businesses that want predictable monthly outgoings for cash flow planning
Variable direct debit	The amount taken follows your actual usage, so it is higher in months you use more energy and lower when you use less	Businesses with seasonal or unpredictable usage who would rather pay closer to what they actually use, month to month

British Gas Business gives a worked example of how a fixed amount might be calculated: as an illustration only, with figures for explanation rather than real prices, if your annual usage totalled £1,200 and you had a £600 outstanding balance, the supplier might divide the combined £1,800 across 12 months to set your monthly direct debit at £150. Your own figure will depend entirely on your actual usage and account history.

Can a supplier require you to pay by direct debit?

Some do. Octopus for Business, for example, requires an active direct debit on all of its business tariffs, even where a customer also chooses to top up their account manually by bank transfer. This is a supplier-specific term rather than a universal rule, so check your own contract or ask before you assume you have a free choice of payment method. If direct debit is a condition of your tariff and you would rather not use it, you may need to look at a different supplier or tariff that offers more flexibility, accepting that this could affect the rate you are offered for the reasons explained above.

What if you cannot or would rather not pay by direct debit?

Ask your supplier directly what your options are. British Gas Business points customers who cannot pay by direct debit to the payment methods listed on the back of their bill, which suggests alternatives exist even where direct debit is the headline option being promoted. Be aware that:

• A non-direct-debit rate may be higher, reflecting the extra credit risk and administrative cost the supplier is carrying.
• You may be asked for a security deposit where a supplier sees your payment method as increasing its risk, covered in our guide to business energy credit checks and deposits.
• You are still responsible for paying on time, whatever method you use, and missing a payment carries the same consequences regardless of how you were set up to pay.

What protects you if a direct debit goes wrong?

The Direct Debit Guarantee. British Gas Business confirms this directly: if an error is made taking your direct debit payment, whether the mistake is the supplier’s or your bank’s, you are entitled to a full and immediate refund. This protection is a feature of the UK banking industry’s direct debit scheme generally, not something any individual energy supplier invented, and it applies regardless of which supplier or bank you use.

What happens if you pay late?

Business energy debt is treated differently from a domestic bill running late, because a commercial energy contract is a business-to-business contract for the supply of goods and services, and English law has specific rules for exactly this situation. The Late Payment of Commercial Debts (Interest) Act 1998 gives an implied right to statutory interest on a “qualifying debt” created by such a contract, where both sides are acting in the course of a business. In practical terms, this means a supplier has a statutory backstop entitling it to charge interest on an overdue business bill, separate from and in addition to any late payment terms it puts in its own contract.

That statutory right can be varied or replaced by your contract, but only within limits. The Act says a contract term that tries to remove the right to statutory interest is void unless the contract provides a “substantial contractual remedy for late payment” instead. In practice, most business energy contracts set out their own late payment terms, such as a specified interest rate or an administration charge, precisely so that this substitutes for the statutory default. Read your contract’s payment terms to see what actually applies to you, rather than assuming either the statutory rate or no consequence at all.

If missing a payment has already become a bigger problem than a one-off late bill, our guide to business energy debt and arrears covers what happens next and how disconnection actually works.

What if your direct debit does not match your usage?

This is one of the most common billing complaints, and it usually comes down to estimated readings rather than the payment method itself. If your direct debit was set based on an estimate that turns out to be wrong, or your usage has genuinely changed, contact your supplier to ask for a review. Suppliers generally adjust the payment amount, up or down, once they have accurate consumption data, and can usually apply this going forward rather than making you wait for the contract to end. Providing your own meter readings regularly, where you are not on a smart meter that reports automatically, is the simplest way to keep a fixed direct debit tracking reality. Our guide on how to read a business energy bill explains how to check whether a bill is based on an actual or estimated reading in the first place.

Standing order versus direct debit: does the difference matter?

Both move money from your account to your supplier automatically, but the control sits in different places. With a direct debit, the supplier (within the rules of the Direct Debit Guarantee) can vary the amount it collects, for example to reflect a change in your usage or an updated estimate, and it notifies you in advance of a change. With a standing order, you set the amount and date yourself through your own bank, and the supplier cannot alter it. That gives you more control, but it also means a standing order will not automatically adjust if your bill goes up or down, so you need to actively update it yourself if your circumstances change. It is worth checking with your supplier whether standing order is even an accepted option, since some prefer or require direct debit specifically because of the flexibility it gives them to track your changing usage.

Does your payment method affect your unit rate or standing charge?

Not directly in the sense of a separate line item, but indirectly, yes. A supplier prices a contract based partly on the credit risk you represent, and your chosen payment method is one input into that risk assessment, alongside your credit history and billing frequency. Two businesses with identical usage can end up with different headline rates if one pays by direct debit and the other does not, simply because the supplier is pricing in a different level of certainty. Our guides to unit rates and standing charges and business energy standing charges explain what these figures actually represent on your bill, separate from the payment question covered here.

Managing payments across multiple sites

If your business operates from more than one premises, you may be able to consolidate billing and payment onto a single account or direct debit rather than managing each site separately, depending on what your supplier offers. This can simplify cash flow and give you one point of reconciliation instead of several. Our guide to multi-site business energy covers how contracts and billing are typically structured across more than one location, which is worth reading alongside this guide if payment administration across sites is becoming a burden.

How to change your payment method or amount

1. Contact your supplier directly, since payment terms are managed through your account rather than through a general request.
2. Ask what alternatives exist for your specific tariff, since some contracts tie a rate to a particular payment method.
3. Get any change confirmed in writing, including the new amount and date if you are changing a direct debit.
4. Check whether changing method affects your rate, since moving away from direct debit can sometimes mean a different, less favourable price.

Once your payment arrangements are settled, it is worth checking your rate is still competitive. You can compare business energy quotes with us at any time.
