Price Cap Rates by Payment Method: Direct Debit, Prepayment and Standard Credit

The energy price cap is not one number. It is a family of maximum rates, and the payment method a household uses decides which member of that family applies. For the cap period from 1 October to 31 December 2025, the direct debit cap level was £1,755 a year for a typical customer, the prepayment level was £48 lower than direct debit, and standard credit customers paid an additional £136 compared with direct debit¹. Same tariff, same household usage, three different bills.

The reason is cost. The cap, as set out in law, works by setting a maximum that suppliers can charge per unit of energy, including a daily standing charge². It applies to default tariffs regardless of how you pay, whether by direct debit or a prepayment meter³, and it covers customers paying by standard credit, direct debit, prepayment meter or an Economy 7 meter⁴. But suppliers face different costs serving each payment type: collecting cash and cheque payments costs more than an automated transfer, and serving customers in debt costs more still. Ofgem builds those differences into the cap, so the maximum rate itself varies by payment method.

For a household thinking about energy independence, the payment method is one of the few levers on a bill that needs no equipment and no capital. It is also a reminder of what the cap does not do: it caps the rate a supplier can charge, but it does not cap the bill, and it does not remove the household's dependence on the supplier, the wholesale market or the network. Our pillar page on energy bills and the price cap sets out the wider picture.

What the energy price cap covers and its limits

The price cap sets a ceiling on the rates a supplier can charge on a default tariff: a maximum price per unit of energy and a maximum daily standing charge². It applies to these default tariffs no matter how the customer pays³, and it covers the four payment routes Ofgem lists⁴:

• Standard credit, where payment follows a bill
• Direct debit
• Prepayment meters
• Economy 7 meters

What it does not do is cap the total bill. A household that uses more energy pays more, because the cap limits the price of each unit, not the number of units. Nor does it apply to every tariff: fixed tariffs, green tariffs and time-of-use tariffs sit outside the cap, so a household on a fixed deal is not affected by its movements. The cap is a backstop for households that have not switched or whose fixed deal has ended, not a guarantee of the cheapest available rate. Ofgem has repeatedly encouraged consumers to switch to save money, because fixed deals can sit below the cap.

The cap also does not protect against the standing charge, which is charged every day regardless of use. That daily fee is inside the cap, but it is a floor under the bill rather than something the cap removes: a household that uses no energy at all still accrues the standing charge. We cover that in detail in standing charges.

Direct debit: cheapest way to pay on credit under the cap

For the cap period from 1 October to 31 December 2025, the direct debit cap level was £1,755 a year for a typical customer, an increase of £35 (2%) on the previous quarter's level of £1,720¹. Direct debit is the cheapest of the credit payment methods because it is the cheapest for a supplier to operate: payments are automated, collection failures are rarer than with cash and cheque, and bad debt is lower.

The cap's cost breakdown for direct debit customers shows how the allowance is built. For the July to September 2025 period, the direct debit cap included an operating margin allowance (earnings before interest and tax) of £43 a year, a levelisation allowance of £8 and headroom of £18⁷. These are the supplier-facing components: the margin the cap permits a supplier to earn, an allowance for smoothing costs across the year, and headroom that lets suppliers price within the cap without breaching it.

The direct debit level matters beyond its own customers because it is the baseline against which the other two levels are measured. When Ofgem says prepayment customers pay a certain amount less, or standard credit customers a certain amount more, the comparison is against this direct debit figure. Our page on direct debit payments and credit balances explains how the monthly amount is set and what happens to credit that builds up.

Prepayment meters: how pay-as-you-go users are affected

A prepayment meter lets a household pay for electricity or gas in advance rather than after using it⁸. These meters require customers to pay before they use the energy, on a pay-as-you-go basis⁹. Around four million households were on prepayment meters when the cap level for them was set at £1,156 a year including VAT in 2021¹⁰, and the protection has a longer history than the main cap: households using a prepayment meter were protected by a separate "prepayment" price cap, sometimes called a safeguard tariff, from 2018¹¹. That earlier cap itself followed a Competition and Markets Authority remedy, a limited, short-term cap on prepayment prices introduced in 2016¹², which moved every six months in line with a range of cost indices¹². The Scottish Government noted at the time that, with the exception of that limited prepayment cap, no wider intervention in the market was intended¹³.

For the cap period from 1 October to 31 December 2025, the prepayment cap level increased from £1,672 to £1,707, a £35 (2%) rise on the previous quarter¹. Crucially, the prepayment cap level was set £48 lower than the direct debit level¹. In the previous quarter the gap was £46¹⁴, and for Economy 7 prepayment customers the difference was £25 less than paying by direct debit¹⁴.

The prepayment discount reflects policy choices rather than pure cost. Prepayment customers are more likely to be on low incomes and in vulnerable circumstances, and successive governments have chosen to hold their cap level below the direct debit level rather than recover the extra costs of serving them through higher rates. The practical effect for a pay-as-you-go household is that the cap works differently from the credit caps: there is no bill to challenge, but the unit rates and standing charge loaded onto the meter are capped in the same way. Our pages on prepayment meters and prepayment vs direct debit cover how topping up and emergency credit work in practice.

Standard credit: the costliest payment option under the cap

Standard credit means paying on receipt of a bill, typically by cash or cheque. Ofgem's position is consistent across cap periods: standard credit is the most expensive payment method option under the price cap¹. For the cap period from 1 October to 31 December 2025, the standard credit cap level increased from £1,855 to £1,890, a £35 (2%) rise¹, and customers paying this way paid an additional £136 a year compared with direct debit customers¹.

The premium has varied as costs have moved:

The direction of travel is upward, and Ofgem's debt strategy explains why: the standard credit price includes a £135 premium specifically due to the costs of debt⁵.

That debt link matters for understanding who pays. Around 16% of customers pay by standard credit, and research suggests up to 43% of them do not realise this is the most expensive way to pay for energy⁵. Standard credit also becomes the default payment method where a direct debit fails, or where prepayment is not an appropriate way for a customer to pay⁵. A household can therefore slide onto the highest cap level not by choice but by circumstance, for example after a missed direct debit.

Our page on standard credit vs direct debit compares the two in detail.

Standing charges: the daily cost every household pays

The standing charge is a fee paid each day, even if no energy is used that day¹⁶. It cannot be opted out of or reduced: it is a daily charge paid for a range of services, from maintenance to support services¹⁷. The Commons Library describes it plainly:

For the cap period from 1 January to 31 March 2026, the cap included an electricity standing charge of 54.75p a day and a gas standing charge of 35.09p a day³. Standing charges have moved in both directions recently:

• From 1 July 2025 they fell by £19 (6%) a year for most households, with the typical electricity standing charge down 2.4p a day (5%) and gas broadly down 2.8p a day (9%), including VAT⁷
• For the October to December 2025 period, they rose again, by 4% for electricity and 14% for gas¹⁹

Part of what sits inside the standing charge is policy cost. The Warm Home Discount scheme's costs were recovered by suppliers through the standing charge, a fixed daily fee applied to all customers regardless of energy usage²⁰, and Ofgem reported that the expansion of the scheme added a total of 7p per day to standing charges¹⁹. This is the structural criticism of the standing charge: it spreads social and policy costs across every household, including those that use very little energy. A few zero standing charge deals exist, but they are very rare and come with catches¹⁷. Ofgem has consulted on requiring suppliers to offer a tariff with a standing charge priced £150 below the cap's nil-consumption level per year²¹, which would give low-usage households a genuine alternative. We cover the debate in standing charge reform.

Why there are 14 regional caps rather than one

The cap a household actually faces depends on where they live, their payment method, their fuel type and their meter type¹⁶. A separate price cap is set for each of the 14 regions and applies throughout the region, with no breakdown below regional level²². The licence condition behind the cap, SLC 28AD.1, confirms that the price cap is calculated depending on a number of factors, including a customer's location and, for electricity, whether their tariff uses a multi-register or single-rate metering arrangement²³.

The regional differences are not cosmetic. For the July to September 2026 period, the gas benchmark maximum standing charge for the Southern Western region was £99.68, with an annual bill of £776.07 at 9,500 kWh of gas, under the "other payment method" category²⁴. A household in a different region faces a different standing charge and different unit rates for the same usage. The drivers are the costs of transporting energy: Ofgem cited increases to parts of the costs of transporting energy in Great Britain, covering England, Scotland and Wales, as one reason for a cap rise⁶.

When standing charges were reduced nationally from 1 April, Ofgem noted that Britain's standing charges would reduce for most households, but some regional variation remains². So a household comparing its bill with a relative in another region will see different figures even on the same tariff and payment method. Our page on electricity and gas unit rates by region gives the regional detail.

How Ofgem sets and revises the cap level

The cap is set using a bottom-up cost assessment approach²⁵: Ofgem builds up an allowance for each cost a supplier faces, from wholesale energy to network charges, policy costs and operating costs, and the resulting total sets the maximum. Importantly, one cap level is set for all suppliers²⁶: an efficient supplier can undercut the cap, but no supplier can exceed it on a default tariff.

The reset mechanism has evolved. The original prepayment cap moved every six months in line with cost indices¹², and the default tariff cap was designed to be adjusted using cost indices and data outside suppliers' control, similar to the existing safeguard tariff²⁷. In 2019, Ofgem reset the level of the cap in August for a six-month winter period beginning on 1 October²⁸. Earlier still, the Energy Price Cap was reviewed twice a year based on the latest estimated costs of supplying energy²⁹. Today the rhythm is quarterly: Ofgem updates the price cap every three months³, with each period lasting a quarter and the new levels announced in advance.

The benchmark consumption behind the headline figures has also been reviewed. The benchmark used in the price cap was based on Typical Domestic Consumption Values from 2017³⁰; following a review decision, from 1 January 2026 the single-rate electricity benchmark is 2,700 kWh a year and the gas benchmark is 12,000 kWh a year, with a single benchmark maintained across all payment types³⁰. Adopting the latest values increased the cap level by about £9 a year for a typical customer³⁰. Our pages on the typical household bill and typical domestic consumption values unpack what those figures mean for real households.

Future direction of the price cap

The cap's recent history has been volatile in both directions. In the fourth quarter of 2022 the planned increase was a further 80%²², a period of crisis-level wholesale prices. Since then the direction has generally been down: average prices under the cap in July to September 2024 were 21% lower than in the same period in 2023³¹, the cap was falling in July 2025³², and at the start of April 2026 action taken at the Budget saw the cap fall by 7%³³.

Two structural changes are in prospect:

• Half-hourly settlement. Ofgem has consulted on updating how it sets the cap level for single-rate customers, those who pay the same price for electricity regardless of when they use it, as part of the move to market-wide half-hourly settlement³⁰.
• A lower standing charge option. The consultation on requiring a lower standing charge tariff²¹ would, if implemented, give every household a route to a standing charge £150 a year below the cap's nil-consumption level, changing the economics for low-usage homes and for households that generate much of their own power.

For a household planning its energy position, the practical reading is this: the cap resets every three months, the gaps between payment methods are reviewed with it, and neither the levels nor the gaps can be relied on to stay where they are. What persists is the structure: direct debit is priced as the cheapest credit method, prepayment is held below direct debit, and standard credit carries a premium tied to the costs of debt. A household that keeps its payment method in good order, and watches the quarterly announcements, holds the parts of the bill it can control.
