Direct Debit Too High in 2026? How to Check It

Last updated: Thursday 29 October 2026

For the current Ofgem cap, unit rates and past quarters, see our energy price cap page.

In short: A Direct Debit that goes up after the price cap changes is not always a mistake. Your Direct Debit is an estimate that spreads your yearly cost into equal payments; it is not the price cap. Ofgem’s typical dual-fuel bill for 1 October to 31 December 2026 is £1,723 a year by Direct Debit (Ofgem, 26 August 2026), but that is for typical use (2,500 kWh of electricity and 9,500 kWh of gas), not your bill. Check the usage your supplier has assumed before you accept or challenge a new amount.

Why Direct Debits change when the cap changes

The price cap sets the maximum unit rates and standing charges on default tariffs. Your Direct Debit is a separate payment plan that collects roughly the same amount each month, so cheaper summer months help cover the winter. When rates change, suppliers often re-estimate your yearly cost. Some change your payment straight away, others at the next review.

£1,723 divided by 12 is about £144 a month for a typical home. If you use more heating or someone is at home all day, a correct Direct Debit can be well above that. A Direct Debit still based on summer use can look low in October and then leave you with a debt in January.

Is a higher Direct Debit fair?

Not always, but often. Reasons an increase can be right:

• unit rates or standing charges went up under the new cap

• your last review underestimated your winter gas use

• you built up a debt over the summer

Reasons to question it:

• it assumes much more energy than you used in the last 12 months

• it ignores a large credit on your account

• you have already switched or fixed, and it is still based on your old tariff

Ask your supplier for the yearly kWh and £ behind the new amount, and compare it with your meter readings or app history.

Direct Debit checklist

1. Find your last annual statement and the letter about your new Direct Debit.

2. Find 12 months of electricity and gas kWh from your app or meter readings.

3. As a rough check, multiply your kWh by the unit rates above and add the standing charges for 365 days.

4. If the supplier’s yearly figure is far above your own, ask for a review.

5. If you are on a default tariff with no exit fee, compare deals for your postcode, meter type and payment method.

6. Switch only if the first-year total is lower after any exit fees, then set your new Direct Debit from your real usage.

Examples (illustrations, not quotes)

Flat with low gas use: last year it used 1,800 kWh of electricity and 6,000 kWh of gas. A Direct Debit based on the full typical £1,723 is probably too high, so ask for a review using your readings.

Family home with the heating on early: usage is above typical, so an increase can be fair. A fixed deal could still cost less than the default tariff.

Recently moved in: the first Direct Debit is often a guess. Send readings early and check again after four to six weeks.

Credits and debts

A credit means you have paid more than you have used. It is your money, and you can usually ask for a refund or a lower Direct Debit. A debt means you have paid too little; cutting your Direct Debit to an unrealistically low figure only leads to a bigger bill later.

Mistakes to avoid

• Do not cancel a Direct Debit without agreeing another way to pay. Standard credit is more expensive: Ofgem’s typical standard credit bill is £1,861, compared with £1,723 by Direct Debit (Ofgem).

• Do not keep a very low Direct Debit because it suited the summer.

• Check your smart meter data after a move or meter change; missing days can make estimates wrong.

If your supplier’s app shows a projected yearly bill, compare it with your Direct Debit. If they differ by hundreds of pounds, ask for a review. If you are on a payment plan or need extra help, tell your supplier before accepting an automatic increase.

FAQ

What is the price cap for Direct Debit customers?

Ofgem’s typical dual-fuel Direct Debit bill for 1 October to 31 December 2026 is £1,723 a year. Your bill depends on your usage, region, meter and payment method.

Why did my Direct Debit go up?

Default unit rates and standing charges changed with the new cap, and suppliers often re-estimate your yearly cost at the same time. Ask for the kWh behind the figure if the increase looks too big.

Is £1,723 what I will pay?

Only if your usage matches Ofgem’s typical figures and you are on a default tariff paid by Direct Debit. Most homes are different.

Can I lower my Direct Debit?

Often, if you have a credit or use less than the supplier assumed. Suppliers can refuse an amount so low that it would build up a debt.

Should I switch if my Direct Debit looks wrong?

First check the usage figures. Then compare deals, and switch if the first-year total is lower after any exit fees.

Does a fixed tariff follow the price cap?

No. Fixed deals are outside the cap. A Direct Debit change on a fix reflects your contract rates and usage.

What happens to a credit on my account?

It is your money. You can usually ask your supplier for a refund or to use it to lower your Direct Debit.
