Why Is My Energy Bill So High? Bills and Direct Debits Explained

A higher energy payment does not always mean you suddenly used more gas or electricity. It could reflect a tariff change, an estimated reading or money owed from an earlier period. Work through the checks below to separate the cost of your energy from the amount being collected from your bank account.

Your statement records energy charges and account activity. A regular Direct Debit is a payment into that account, usually based on estimated annual costs. Citizens Advice explains that a supplier may increase it if previous payments did not cover usage or if money needs to be repaid.

Illustrative example: if expected future energy costs average £130 a month and you agree to repay £240 over twelve months, a payment could be £150. The extra £20 is repayment, not a higher unit rate. Ask your supplier to separate the elements rather than treating the whole payment as your monthly consumption.

Look for wording such as estimated or an E beside the readings. If the estimate is wrong, submit a current meter reading and ask for an updated bill. Citizens Advice notes that a smart meter can also produce estimated bills when it is not communicating correctly.

A new actual reading after months of low estimates can produce a catch-up charge. That is different from using all the extra energy in the latest month. Compare the billed dates with previous statements and keep a dated photo of your meter reading if you need to query the calculation.

Ofgem explains that energy charges include a price per kWh and a daily standing charge. Check whether your tariff changed and whether this statement covers a longer period. Standing charges normally continue even on days when you use no energy.

For an electricity example using invented rates, 240 kWh at 25p costs £60. Add a 50p standing charge for 30 days and the total is £75, before any other account adjustments. Use rates on the same VAT basis as your statement. For gas, use the billed kWh figure rather than assuming the raw meter reading is already in kWh.

Add up payments credited to your account and check for missing or duplicated entries. Look at the opening balance as well as the closing balance. Money in credit is not automatically evidence of overcharging: Ofgem says summer credit can help cover higher winter consumption.

You can contact your supplier to request credit back, but consider upcoming bills before withdrawing it. Ask for the balance to be checked against current readings so the refund is based on up-to-date charges.

If the payment still looks wrong, ask which annual usage, tariff rates and account balance the supplier used. Citizens Advice says you can challenge an increase and request an explanation. If the assumptions are inaccurate, ask for a revised payment. Keep the explanation and any agreed change in writing.

If you cannot afford the proposed payments, tell your supplier and discuss a payment plan. If the calculation remains disputed, use the supplier’s formal complaints process. Do not treat reducing the payment alone as evidence that the underlying charges have been corrected.

Collect a recent statement, your tariff details, current readings and a record of payments. Write down exactly what changed: the kWh, the rate, the billing period or the monthly collection. A precise question is easier to investigate than simply saying the bill feels high.

An average-household comparison can be a useful starting point, but it cannot establish that your supplier made an error. Your own meter readings, tariff and account history are the evidence that matters.
