The Warm Home Discount

The Warm Home Discount is a one-off £150 discount applied to household electricity bills, funded by a levy on all domestic gas and electricity customers and delivered by the larger energy suppliers. It is a fuel poverty reduction scheme, reducing the energy costs of low-income and vulnerable households across Great Britain, and it has run since 2011¹. Around 6 million households now benefit from a £150 rebate off their winter energy bill, and the measure has been confirmed through to 2030-31³.

The discount is not paid to the household. Your electricity supplier applies it to your bill, so it reduces what the account owes rather than arriving as cash or a voucher⁴. For winter 2026 to 2027 the qualifying date is 23 August 2026, and three conditions must all have applied on that date: your supplier is part of the scheme, you or your partner receive certain means-tested benefits, and your name or your partner's is on the electricity bill⁵.

The scheme operates as two separate schemes, one covering England and Wales and the second covering Scotland, and it does not run in Northern Ireland². Most eligible households in England and Wales receive the rebate automatically through data matching, while some households in Scotland must apply through their supplier⁵.

What the Warm Home Discount is: £150 off your electricity bill

The scheme requires large domestic energy suppliers to provide an annual discount of £150 to eligible households¹. It is described in official statistics as a one-off £150 discount off household electricity bills, and the same £150 figure appears across the government's own guidance and consultation material¹. The discount is applied to the electricity account, and the money is not paid to you⁴.

The scheme's purpose is narrow and specific. It is a fuel poverty reduction scheme, reducing the energy costs of low-income and vulnerable households across Great Britain since its inception in 2011⁸. It helps households in, or at risk of, fuel poverty with direct energy bill payments as well as other financial and energy-related support⁵. Since 2011 it has helped around 3 million low-income and vulnerable households every year, and over its life more than £4 billion-worth of direct assistance has been provided⁶.

The value has moved over time. The scheme was worth £140 for each household at one point, and the extension announced in 2022 lifted it to £150 while widening the number of households covered⁹. The £140 figure still appears in some older material, so a household reading an out-of-date page may see a smaller number than the one that now applies. The current published figure is £150.

For a household's energy independence, the discount is a partial offset rather than a step towards self-sufficiency. It reduces a bill that still depends on the grid and on a supplier, and it does nothing to change how the home is heated or how much energy it uses. What it does is lower the cost of the dependence that remains, for households on the lowest incomes.

Who qualifies: the core group and the benefits that count

Eligibility in England and Wales has been organised around two groups. Core Group 1 covers receipt of the Guarantee Credit element of Pension Credit. Core Group 2 covers receipt of a qualifying means-tested benefit, by the person named on the bill, or their partner or legal representative, on the qualifying date¹¹. The Core Group 2 qualifying benefits for winter 2025/26 are set out below⁷.

The government has decided to merge the current Core Group 1 and Core Group 2 into a single Core Group in England and Wales, retaining the expanded eligibility criteria from 2025/26¹¹. That simplification matters for households because it removes a distinction that previously decided whether a payment arrived automatically or needed a claim.

The high-cost-to-heat eligibility threshold that applied in England and Wales has been removed from October 2025, allowing all households in receipt of specified means-tested benefits to qualify⁷. That threshold was the reason some households on the right benefit still missed out, because their property was judged not expensive enough to heat. Its removal widens the group considerably.

The scheme's own eligibility statement describes the criteria used to determine eligibility for a rebate under Core Group 2 as low-income criteria, meaning qualifying means-tested benefits, and eligible property types¹². The property-type condition is the part that has changed most, and it is the part a household is least likely to be able to judge for itself.

England, Wales and Scotland: how eligibility differs, and why Northern Ireland is excluded

Since 2022 the Warm Home Discount has operated as two separate schemes, one covering England and Wales and the second covering Scotland². The legislation reflects that split: the Warm Home Discount (England and Wales) Regulations 2026 extend to England and Wales only, apart from two regulations that also extend to Scotland, and the Warm Home Discount (Scotland) Regulations 2026 extend to Scotland only, again apart from two regulations¹³. Earlier regulations from 2022 and 2011 show the same pattern of territorial extent¹⁵.

The practical difference is in how a household gets the money. In England and Wales the majority of eligible households receive their rebates automatically from their energy supplier through data matching⁵. In Scotland, only customers on a low income need to apply through their energy supplier, and eligible energy customers should receive the discount by 31 March 2026⁷. Scotland also has its own Winter Heating Payment, which is an automatic payment that usually requires no application form¹⁷.

Scotland's Core Group eligibility is being expanded to align with the same qualifying benefits list as the Scottish Winter Heating Payment from 2026/27¹¹. That alignment is intended to make the two schemes easier to understand together, since a household in Scotland may be dealing with both.

Northern Ireland is excluded. The Warm Home Discount Scheme does not run in Northern Ireland, although an Affordable Warmth Scheme is available there². A household in Northern Ireland therefore looks to the Northern Ireland energy grant landscape rather than to this scheme, and the £150 electricity discount described here does not apply.

How the discount is paid, and when it arrives

The discount is applied to the electricity bill by the supplier, and the money is not paid to the household⁴. That single rule explains most of what follows. There is no cheque, no voucher and no bank transfer. The supplier credits the account, and the effect is a lower balance or a lower direct debit.

Timing has varied across scheme years. In an earlier scheme year the discounts were taken automatically from energy bills before March 2021, with most pensioners receiving their discounts between the announcement and January¹⁸. More recently, eligible energy customers should receive the discount by 31 March 2026 for winter 2025/26⁷. The pattern is that payments land across the winter and are complete by the end of March.

For a household on a prepayment meter the mechanism is the same in principle, because the discount attaches to the electricity account rather than to a payment method. The £150 is credited to the account, which reduces what the meter collects or builds credit on it. The scheme statistics describe the £150 Warm Home Discount as reaching around 6 million households, and prepayment customers are among them³.

What a household should expect in practice is a line on a statement or a change in the account balance, not a separate payment. That is also why a missing discount is usually a records problem: if the benefit record and the electricity account have not been matched, the supplier has nothing to apply the discount to.

Automatic payment or application: which route applies to you

Through data matching, the majority of eligible households receive their rebates automatically from their energy supplier⁵. Around 96% of discounts were matched in a recent scheme year, which is the clearest available measure of how well the automatic route works⁶. If you receive Pension Credit Guarantee, the payment arrives automatically¹⁹.

The automatic route depends on records lining up. The government has used letters to reach households that meet part of the criteria but are not yet benefiting: a further 220,000 pensioners who met part of the eligibility criteria but were not yet benefiting received a letter encouraging them to claim via a dedicated helpline¹⁸. That is the model for the gap cases, where the data match has not produced a payment and a claim has to be prompted.

Scotland is the main exception to the automatic model. Only customers on a low income in Scotland need to apply through their energy supplier⁷. A household in Scotland that has not applied should not assume the payment will arrive on its own.

Park home residents have a separate route again. The Park Homes Warm Home Discount scheme is for permanent residents of park homes who pay the site owner for their electricity, paying council tax and receiving certain benefits or on a low income; they need to apply each year and only one application per household is considered⁷. For 2026/27, applicants must be a permanent resident of a park home, pay the park site owner for electricity usage and be on a relevant qualifying benefit or demonstrate household income or fuel poverty criteria⁵. Eligibility is decided by the scheme administrator, currently Charis Grants⁵.

Caravan residents have their own evidence requirement: they need to contact the Warm Home Discount helpline and provide evidence that the caravan is their sole, legal residence and that the applicant is named on the electricity bill⁵.

Switching supplier: when you keep the discount and when you lose it

If you pay a supplier directly for the electricity or gas you use at home, you can choose to switch to a different supplier or tariff at any time²⁰. Switching is a normal part of managing a bill, and the Warm Home Discount does not remove that right.

What switching does affect is whether the discount follows. The scheme requires large domestic energy suppliers to provide the discount, and suppliers with more than 1,000 domestic customers, plus other suppliers who elect to take part, offer the discount and recoup the costs from the energy bills of all their customers⁷. A supplier that is not part of the scheme cannot apply the discount, so a household that moves to a non-participating supplier loses the payment for that year.

The rules anticipate suppliers leaving the scheme. A supplier that participated in the preceding scheme year but not the current one must place a statement on its website that it is not participating in the Warm Home Discount scheme, and must notify former core group customers in writing, on or before the date one month after the scheme year starts²¹. That notification duty exists precisely because customers would otherwise not know their discount had gone.

The practical sequence for a household is to check the supplier's participation before switching, and to check it again if the discount does not arrive. The government publishes the list of suppliers that take part, and the eligibility rules require the supplier to be part of the scheme on the qualifying date⁵.

What the discount is worth against your bill, and how that has changed

The £150 figure is fixed for the scheme, but its weight against a bill depends on the bill. The scheme was extended from 2 million people to 3 million people, with the uplift to £150, in the 2022 announcement²². Before that it was worth £140 for each household⁹. The direction of travel has been upward in both coverage and value.

The way the cost is recovered has also changed. From April 2026 the recovery of Warm Home Discount costs shifts from the standing charge to the unit rate on household energy bills³. That is a change in how the levy is collected rather than in the discount itself, but it changes which part of a bill carries the scheme's cost.

The expansion has been presented as cost-neutral to the system as a whole. The expansion of the Warm Home Discount will be offset by new efficiency savings across the energy system, including Ofgem's confirmed decrease in the operating cost allowance of the price cap and savings from reducing consumer debt recouped via a levy on all bills¹⁰. That is the government's stated position on the net effect.

For a household, the honest summary is that £150 is a meaningful but partial contribution. It is a one-off payment against a bill that recurs, and it does not scale with the size of the bill or the size of the home. Its value to a household on a low income is real, and its limit is that it is a fixed sum.

How the scheme is funded and what it adds to everyone's bill

The Warm Home Discount is funded through a levy on all domestic gas and electricity customers². That is the central fact about its economics: the money comes from bill payers collectively, and is redistributed to eligible households through their suppliers. The scheme primarily provides support through the provision of £150 energy bill rebates, funded through a levy on all domestic gas and electricity customers⁸.

The levy is collected by suppliers and recouped through bills. Suppliers with more than 1,000 domestic customers, plus other suppliers who elect to take part, offer the discount and recoup the costs from the energy bills of all their customers⁷. A household that does not qualify therefore contributes to the scheme through its bill, and a household that does qualify receives a share back.

The scale of the redistribution is substantial. The scheme has been running for 14 years, and over that time more than £4 billion-worth of direct assistance has been provided⁶. It has helped around 3 million low-income and vulnerable households every year since 2011⁶. The expansion announced for winter 2025/2026 was expected to bring 2.7 million extra households into receipt of £150 off their energy bills¹⁰.

The scheme's cost sits alongside other levies and obligations on bills, including the Energy Company Obligation and the price cap's own allowances. For a household thinking about energy independence, the levy is a reminder that a grid-connected home pays into collective schemes whether or not it draws on them, and that the only way to reduce exposure to those levies is to reduce the bill they are charged on.

How long the scheme runs, and what happens if your supplier fails

The scheme covers England, Scotland and Wales and will run until 31 March 2031². The extension from 2026 to 2031 followed the Department for Energy Security and Net Zero's consultation and government response on extending the scheme⁸. The scheme years 17 to 20 are defined in legislation as a period of 12 months beginning with 1st April in any of the years from 2027 to 2030¹³.

The scheme has been extended before. It was originally in operation for seven years, until 31st March 2018, and was then continued²¹. An earlier extension covered scheme year 2015-16²³. The pattern is that the scheme is renewed in fixed periods rather than being open-ended, so a household should not assume it will exist indefinitely beyond the published end date.

Supplier failure is handled through the scheme's structure rather than through a household claim. The discount is an obligation on suppliers, and the rules set out what a supplier must do when it stops participating, including the website statement and the written notification to former core group customers²¹. There are also reporting duties, set out below¹⁶.

• Undelivered rebate reporting, scheme year 6: 1st July 2017 to 30th September 2017¹⁶
• Undelivered rebate reporting, scheme year 7: 1st April 2018 to 31st August 2018¹⁶
• Undelivered rebate reporting, each subsequent scheme year: 1st April to 31st August following the scheme year¹⁶
• Spending notification, from scheme year 8: a supplier must notify the Authority by 15th December in the scheme year if it considers it will not incur at least the notified spending²¹

What this means for a household is that the discount is tied to the supplier's participation and to the supplier's own compliance. If a supplier fails or withdraws, the household's route to the discount is through the supplier that takes over the account, and the notification duties exist to make that visible.

The Warm Home Discount alongside the price cap and other bill support

The Warm Home Discount requires suppliers to provide an electricity bill discount for certain customers²⁴. It is one of several forms of bill support, and it is worth understanding how they sit together.

Warm Home Discount recipients on a standard variable or default tariff were protected by the prepayment price cap until the end of 2018, and were then transferred to the default tariff price cap²⁵. That transition is a reminder that the discount and the cap are separate mechanisms: the cap limits what a supplier can charge per unit and standing charge, while the discount reduces the amount owed.

Other support operates on different triggers. Cold Weather Payments are automatic for those eligible²⁶. The Winter Fuel Payment is a separate payment with its own eligibility rules, and the two are often confused; the comparison of the Warm Home Discount and the Winter Fuel Payment sets out where they differ. The Scottish Winter Heating Payment is an automatic payment that usually requires no application form¹⁷.

The scheme also sits alongside the supplier-funded obligations. The Energy Company Obligation funds physical measures such as insulation and heating, while the Warm Home Discount reduces a bill. A household facing both a high bill and a cold home may need both kinds of support, and they are claimed through different routes.

For energy independence, the honest position is that none of these schemes reduces a household's dependence on the grid or on a supplier. They reduce the cost of that dependence. The step that changes the underlying position is a physical measure, such as insulation or a heat pump, funded through a scheme such as the Boiler Upgrade Scheme, and the Warm Home Discount is best understood as bill relief that runs alongside those efforts rather than a substitute for them.
