Prepayment versus direct debit: satisfaction and costs compared

The newest official survey puts prepayment meter customers at the top of the satisfaction table. In the July and August 2025 findings, satisfaction was highest among prepayment meter customers, and satisfaction with customer service had risen for prepayment customers from 73% to 80%¹. That reverses the position two years earlier, when direct debit payers reported higher satisfaction at 71%, against 66% on prepayment meters and 64% on standard credit².

The cost picture runs the other way. Prepayment tariffs tend to be higher than those paid by direct debit, and almost all companies offer a discount for paying by direct debit, so it is often the cheapest way to pay³. The gap has narrowed at the cap, though: for the cap period that followed 1 July to 30 September 2025, the prepayment cap level was £48 lower than the direct debit cap level⁴.

So the two questions a householder is really asking, which way of paying feels better and which way costs less, have different answers. This page sets out what the consumer data shows, where the price cap gap sits by period and meter type, what changes when a household moves between the two, and what suppliers are obliged to do when a prepayment customer cannot top up.

Satisfaction: prepayment 66% versus direct debit 71%

The headline comparison most people arrive with is the 2023 one. In the August and September 2023 survey, direct debit payers reported higher satisfaction at 71%, compared with 64% on standard credit and 66% on prepayment meters². That was a five point gap in favour of direct debit, and it matched the intuition that paying by direct debit is the easy option and prepayment is the awkward one.

Two years later the order had changed. In the July and August 2025 findings, satisfaction was highest among prepayment meter customers, and satisfaction with customer service had improved for prepayment customers from 73% to 80%, and for standard credit customers from 73% to 79%¹. Ofgem's own analysis of what drives satisfaction notes that prepayment meter customers' satisfaction has improved, matching the satisfaction levels of direct debit customers for the first time⁶.

The earlier data shows how recent that shift is. Ofgem's report records that January to February 2024 data showed prepayment customers were less satisfied than direct debit customers, at 68% against 76%⁷. The same report identifies a likely cause of the turnaround: since July 2023, prepayment meter customers have no longer faced the highest energy costs, which may have gradually influenced satisfaction levels⁷.

It is worth being precise about what these percentages measure. The 2023 figures are overall satisfaction with the supplier by payment method². The 2025 figure of 80% is satisfaction with customer service specifically, and the same survey reports satisfaction highest among prepayment meter customers overall¹. The two are not the same measure, and the documents do not give a single like for like series across both years. What can be said is that the direction of travel for prepayment customers is upward, and that the gap in their favour is new rather than long established.

For a household, the practical reading is that payment method is a weak predictor of how happy someone is with their supplier. The 2021 data, for comparison, put satisfaction among direct debit customers at 75%⁸. Across four surveys the numbers move by a few points either way, and the ranking changes.

Why prepayment customers can be more satisfied once other factors are controlled for

The obvious objection to the 2025 result is that prepayment customers are a different group of people, not a random sample, so comparing raw percentages may mislead. Ofgem's analysis addresses this directly: prepayment customers show higher satisfaction than those on direct debit once other variables are controlled for⁷. In other words, the result survives the obvious controls.

The report offers a cost explanation rather than a service one. Since July 2023 prepayment meter customers have no longer faced the highest energy costs, which may have gradually influenced satisfaction levels⁷. If the main grievance attached to prepayment was that it was the most expensive way to pay, removing that grievance removes the reason for lower satisfaction.

Qualitative research in Scotland points to a second factor: control. The main perceived advantage of prepayment was that it provided a sense of control, allowing users to decide how much money to put into their account and to manage their use of energy accordingly⁹. A household that decides week by week what to spend on energy has a kind of budgeting certainty that a monthly direct debit does not provide, even where the direct debit is cheaper overall.

That control comes with costs that the same research records. Direct debit arrangements were considered a more flexible approach than prepayment, as they allowed customers to negotiate a payment plan with suppliers if bills became unmanageable, whereas there was a perception that this would not be available on prepayment⁹. Prepayment consumers were also far more likely to be rationing their energy use, at 74%, compared with 66% of direct debit and standing order consumers and 68% of all consumers¹⁰. Fourteen per cent of prepayment meter consumers reported seeking financial support from their supplier, against 3% of direct debit customers¹⁰.

The satisfaction advantage, then, is real in the data but narrow in what it covers. It reflects how people feel about their supplier, not how much energy they can afford to use.

Costs: why direct debit is usually cheaper

On price the evidence is consistent and points one way. Prepayment tariffs tend to be higher than those paid by direct debit, and almost all companies offer a discount for paying by direct debit, so it is often the cheapest way to do it³. Paying on receipt of a bill tends to be a more expensive way of paying than direct debit, because most companies offer discounts for setting up a direct debit instead³.

The independent statistics show the same pattern in bill movements. Prepayment electricity bills fell by 16.85% between 2023 and 2024, standard credit bills by 12.28%, and direct debit by 11.11%¹¹. Prepayment bills fell furthest in percentage terms, which is what closes a gap rather than what opens one.

The cap structure explains why direct debit has historically been cheapest. The direct debit cap level for 1 January to 31 March 2025 was £1,738 for a typical dual fuel customer⁵. Within that level, the July to September 2025 breakdown shows an earnings before interest and tax allowance of £43 a year and headroom of £18 a year, with VAT at £82 a year¹². Those are the components that make up the cap, and they apply across payment methods with different totals.

The practical consequence for a household is that the cheapest route is usually the one with the least friction: a direct debit that is set at the right level. Suppliers must ensure that customer fixed direct debit amounts are based on accurate and up to date information to ensure credit balances are not excessive¹³. Under Standard Licence Condition 27, suppliers must take all reasonable steps to ensure the fixed amount of a domestic customer's regular direct debit payment is based on the best and most current information available¹⁴. Where a direct debit has been set too high, that is a licence matter, not simply a matter of preference.

The price cap gap: where prepayment comes out ahead

The price cap does not treat prepayment as the expensive option any more. For the cap period that followed 1 July to 30 September 2025, the prepayment cap level was £48 lower than the direct debit cap level⁴. In the same announcement, customers paying by standard credit were told they would pay an additional £136 compared with those paying by direct debit⁴. Both the direct debit and prepayment cap levels rose by £35, or 2%, compared with the previous period⁴.

The gap varies by period and by meter type, and the documents give several figures rather than one.

The same periods show what standard credit pays over direct debit: £120 more for 1 April to 30 June 2025⁵, £106 more in cap period 12a¹⁵, and £82 more for Economy 7 electricity customers for 1 July to 30 September 2025¹².

Two things follow. First, the prepayment advantage at the cap is small, in the tens of pounds a year, and it is smaller still for Economy 7 households. Second, the gap has been consistent across recent periods, which is what allows Ofgem to say prepayment customers have not faced the highest energy costs since July 2023⁷.

The cap is not the whole bill. Fixed, direct debit tariffs tracking below the April price cap level offered savings of around £50 compared with the upcoming cap level in February 2025¹⁶. A household on prepayment cannot always access those tariffs, which is the point Consumer Scotland has pressed: there should be parity of costs for direct debit and prepay customers¹⁰. The Scottish Government has said it will continue to press for customers with pre-payment meters to access similar tariffs to direct debit customers¹⁷.

Choice: prepayment, direct debit or both

The choice is not simply between two payment methods, because the rules now push households towards direct debit by default in some circumstances. Standard credit becomes the default payment method where a direct debit fails, or where prepayment is not an appropriate way for a customer to pay¹⁸. That matters for anyone whose direct debit has bounced: the fallback is not prepayment but standard credit, which is the most expensive of the three.

The direction of policy has been towards levelising the two cheaper methods. Prepayment meter and direct debit consumers pay the same level of standing charges, a change that opened in April 2024¹⁹. Before that, standing charges differed between the two.

Switching between methods is possible in both directions, and the evidence on what people experience is mixed. Those who had switched from prepayment meters to direct debit described having saved money as a result, but prepayment users were concerned direct debit would make it harder to manage their money²⁰. That is the trade in plain terms: a lower bill against tighter control of the household budget.

The practical route to switching runs through the meter. Switching from an existing gas or electricity prepay meter to a smart credit meter is straightforward for customers who have one¹⁶. A smart meter in prepayment mode can add credit automatically or without having to visit a shop¹⁷. That removes the main practical drawback of traditional prepayment, which is the trip to the shop and the risk of running out at a bad moment.

For a household thinking about energy independence, the payment method is a small lever. It changes what the same units of gas and electricity cost, and it changes who holds the money in the weeks before the energy is used. It does not change where the energy comes from, and it does not remove reliance on a supplier and the grid. The wider picture of what households can and cannot control is set out in what the data says about household energy independence, and the bill components themselves are covered in UK domestic energy prices over time.

What suppliers must now do for struggling prepayment customers

The obligations on suppliers are specific and they apply whether or not the household has asked for help. Suppliers must offer help if a customer cannot afford to top up, for example by giving extra credit in a vulnerable situation²¹. Providing appropriate support to customers in vulnerable situations using prepayment meters, who have self-disconnected or self-rationed or are at risk of doing so, is a licence obligation²².

For heat network customers, the draft guidance goes further. Where a supplier switches an existing supply meter to a prepayment mode without the consumer's consent, the supplier must ensure the consumer receives prepayment meter credit, unless that is technically infeasible or otherwise outside the supplier's control²³. The same guidance obliges suppliers to offer a reasonable amount of additional support credit in a timely manner where a prepayment consumer has self-disconnected or self-rationed in circumstances in which any occupant of the household is in a vulnerable situation²³.

There is also pressure from government on how customers end up on prepayment in the first place. The government has demanded that energy suppliers stop moving customers over to prepayment against their will, and for customers paying by direct debit, the supplier must let them know about a payment increase before it happens.

The evidence on how well this works in practice is mixed. Prepayment meter customers were less likely, at 30%, to agree that their supplier makes it easy for them to contact them, and only 24% would recommend their supplier, compared with 37% of those paying by direct debit or standing order²⁴. Direct debit and standing order customers were more likely, at 46%, than prepayment meter customers, at 28%, to report that their supplier treated them fairly²⁴. Customers paying direct debit or standing order were also more likely, at 58%, than those paying on receipt of a bill at 40% or by prepayment at 35%, to agree that their bills provide guidance²⁴.

For anyone in difficulty, the official position is that it is better to agree a payment plan with your supplier rather than cancelling direct debits and letting debt build up²⁵. The wider data on how many households are in arrears is set out in household energy debt and arrears statistics, and the pattern of running out of credit is covered in self-disconnection and prepayment meter data.
