Paying business energy bills: payment methods and avoiding late fees

Most suppliers let businesses pay by direct debit, and many also accept bank transfer, card or cheque. The terms (including any charge for paying late) are set out in your contract, so read those before relying on any method. If you cannot pay on time, contact your supplier before the due date, not after.

Payment methods to look for

What is on offer depends on the supplier and the contract. Ask about:

• Direct debit: automatic and often the easiest way to avoid missed payments.
• Bank transfer or online banking: good if you want to time payments against your own cashflow.
• Debit or credit card: check whether any fee applies.
• Cheque or other options: slower, with more risk of lateness.

Ask whether there are different terms or prices for different payment methods. Ofgem's microbusiness guidance suggests looking at payment methods as well as contract length when you compare deals. We have not found an Ofgem rule requiring suppliers to offer any particular payment method to business customers. Ask for the payment terms in writing before you sign; see contract terms to check.

How direct debit amounts are set

A fixed monthly direct debit is based on the supplier's forecast of your annual cost, spread over twelve payments. If usage is lower than forecast, credit builds up; if higher, you may owe a balance later. Ofgem's guidance lists fixed direct debits above usage as one way credit accumulates.

Worked example

A small workshop expects 20,000 kWh of electricity a year at an illustrative 28.4p/kWh and 58.0p a day standing charge (Moneysupermarket micro fixed average, October 2026):

• Energy: 20,000 x £0.284 = £5,680.00
• Standing charge: 365 x £0.58 = £211.70
• CCL: 20,000 x £0.00801 = £160.20 (usage is above the 1,000 kWh/month exemption)
• Subtotal: £6,051.90
• VAT at 20%: £1,210.38
• Total: £7,262.28, or £605.19 a month

If actual use is nearer 25,000 kWh, the bill rises to about £9,014: (25,000 × £0.29201 + £211.70) × 1.2 = £9,014.34, where 29.201p is the 28.4p unit rate plus 0.801p CCL. A direct debit based on the lower forecast will leave a shortfall, so review the amount whenever your use changes. Try your own figures in the business energy cost calculator.

Ask for your direct debit to be reviewed after every meter reading, and send readings often; see submitting a business meter reading.

What happens if you pay late

Consequences differ by supplier and contract. Typically they can include a late payment charge or interest, a reminder and then a formal demand, moving to a different payment arrangement, a request for a security deposit (see security deposits) and, ultimately, disconnection. Fee levels vary and are not set by one rule, so check your contract for the exact charge.

Disconnection

Business Debtline explains that suppliers can disconnect a business without a court order, though in Scotland they need a sheriff court warrant to enter premises. Notice periods depend on your contract, so read the disconnection clause now rather than when a letter arrives; you would normally get letters or calls first. Commercial supplies do not carry the same prepayment-meter protections as homes. See disconnection and reconnection.

If you cannot pay

1. Contact the supplier early. Ask for the team that handles arrears and repayment plans.
2. Explain your position. Include why you cannot pay and when things should improve.
3. Offer a realistic plan. Business Debtline says suppliers usually want you to cover ongoing energy use plus an amount towards the arrears, and often check payment history.
4. Renegotiate if things change. Write to the supplier and ask for a revised plan.
5. Get free advice. Business Debtline and Citizens Advice can help.

Disputed bills and payment

If you think a bill is wrong, tell the supplier in writing, pay any amount you agree is correct, and ask for the rest to be reviewed. See disputing a high business energy bill and the Ombudsman route in energy disputes.

Cash-flow habits that help

• Pick a payment date that follows your main customer receipts.
• Put aside VAT; if VAT-registered you can usually reclaim it on business use (see reclaiming VAT).
• Keep an eye on credit and ask for refunds; see refunds and credits.

Payment terms worth negotiating

When you agree a deal, ask whether you can choose the payment date, whether the direct debit can follow your cashflow, and whether the supplier will do a mid-term review of the amount. Suppliers choose which customers they accept, often by credit rating, and they may ask for a deposit or different payment terms if your credit is weak; see credit scores and energy prices.

Keeping records

Save your bills, payment confirmations and any messages about payment plans. If you reclaim VAT, you need valid invoices. If you ever dispute a charge, a clean payment record strengthens your position and shows you acted in good faith.

Do not stop a direct debit as a way of disputing a bill. It can trigger late-payment steps even if you are right about the charge. Ask for the bill to be reviewed and pay the undisputed amount.

VAT and cashflow on the bill

Bills carry VAT at 20% for ordinary business use. A VAT-registered business can usually reclaim it as input tax, while very small supplies (up to 33 kWh a day of electricity or 145 kWh a day of gas) are charged at 5%. Remember that Climate Change Levy of 0.801p per kWh applies from 1 April 2026 unless you are under the de minimis limits. These items arrive on every bill, so when you set aside money for energy, budget for the total including tax rather than the pre-tax figure. If your business is quiet for part of the year, ask whether a seasonal payment pattern is possible instead of equal monthly instalments.

If you run the business from home or share a supply, tell the supplier, because disconnection rules and protections can differ when people live on the premises. Business Debtline also notes that a limited company in difficulty may be able to apply for a moratorium to gain breathing space, and that supply may be protected once an insolvency practitioner agrees to it continuing. Seek independent advice before relying on either.

Next steps

• Find your contract's payment and late-payment terms.
• Check your direct debit against a recent actual reading.
• If you are struggling, call the supplier before the next due date.
