The Warm Home Discount: how it works and who qualifies in 2026

The Warm Home Discount is a one-off £150 reduction applied directly to your electricity bill each winter. You don't receive cash; the money comes off what you owe your energy supplier. Most people who qualify for the Core Group get it automatically, without filling in a single form. If you're in the Broader Group, you may need to take action, but the process is more straightforward than it used to be. This article explains both routes, who falls into each, and what to do if you believe you should be getting the discount but haven't heard anything.

What is the Warm Home Discount and how much is it?

The scheme is run by the Department for Energy Security and Net Zero (DESNZ) and is separate from the Winter Fuel Payment or Cold Weather Payment. The discount is currently set at £150 and applies to electricity bills only, not gas.

The scheme runs from October through to March each year. For the 2025/26 scheme year, eligibility rules and figures remain consistent with the reformed structure introduced in 2022, which expanded the Broader Group and shifted more of the automatic qualification to Pension Credit recipients. If there are changes for 2026, the government publishes updated guidance on GOV.UK, which is worth checking directly.

One thing people often miss: this is an obligation placed on energy suppliers, not a universal entitlement. Your supplier has to be part of the scheme for you to claim it. In practice, all the major household names, including British Gas, EDF, E.ON, Octopus Energy and Scottish Power, are enrolled. Smaller suppliers may not be. You can check participation on GOV.UK.

Who qualifies automatically (the Core Group)?

The Core Group is the simpler of the two routes. If you receive the Guarantee Credit element of Pension Credit and your name is on the electricity bill for your main home, you're almost certainly in it.

The government cross-references its own data with energy supplier records. When there's a match, your supplier is informed and applies the £150 discount without you doing anything. The government writes to you between October and January to confirm you're in the scheme. That letter will name your supplier and tell you when to expect the discount.

A word of caution: the matching process isn't perfect. I've spoken to people who received a letter telling them they were in the Core Group but then found the discount never appeared on their bill. If that happens to you, don't wait. Contact your supplier directly with your letter as evidence and ask them to apply it manually.

If you receive Pension Credit Savings Credit but not Guarantee Credit, you don't automatically fall into the Core Group. You may still qualify through the Broader Group instead (covered below).

Who qualifies through the Broader Group?

The Broader Group covers a wider range of households, including people on certain means-tested benefits who have a low income and high energy costs. The specific qualifying benefits include Universal Credit, Income-related Employment and Support Allowance, Income Support and others, though the full list and the income thresholds can change between scheme years.

Since the 2022 reforms, the government now uses an automated matching system for much of the Broader Group too. If your details match, you may receive a letter, in the same way as Core Group recipients, telling you the discount will be applied automatically. Not everyone gets this, though. Some Broader Group applicants need to call their supplier or apply through an online checker on GOV.UK to confirm eligibility.

The key variable is whether your supplier has enough data to make the match. If they can't confirm your eligibility automatically, they'll ask you to provide details about your benefit claim and household income.

I'd suggest not assuming you'll be contacted if you think you might qualify. Check your supplier's website in October or call them. The earlier you make contact in the scheme year, the less likely you are to miss the deadline.

How is the discount actually applied to your bill?

If you pay by direct debit, you'll usually see a £150 credit appear on your electricity account. Your supplier might apply it as a reduction to a specific bill, spread it across several months or hold it as account credit, depending on how they administer the scheme. If you're in debt to your supplier, they may apply it to reduce that debt instead.

Prepayment meter customers receive the £150 as credit loaded directly onto their meter. In some cases, suppliers issue a voucher that you redeem at a PayPoint or Payzone outlet. If you receive a voucher, act quickly; they have expiry dates, typically 90 days from issue.

If you haven't received the discount by the end of March, contact your supplier. After 31 March, the scheme year closes and any unclaimed discount is lost.

What if you think you qualify but haven't heard anything?

This is where the system can let people down, and it's something I saw regularly in my social work years. Someone would tick every box for a benefit or discount, the letters would go to an old address or get ignored, and by the time anyone looked into it, the window had closed.

If you believe you should qualify and haven't received a letter by December, don't wait for the post. Do both of the following:

Check your eligibility using the GOV.UK Warm Home Discount checker. It takes a few minutes and uses your National Insurance number to look up your benefit status.

Contact your energy supplier directly and ask whether they have you on their records as a potential qualifying customer.

If your supplier tells you you're not eligible and you think that's wrong, you can raise a complaint with the supplier first, and then escalate to the Energy Ombudsman if they don't resolve it. Age UK's helpline (0800 678 1602) can also help you work through the process.

What about tenants and people who don't pay electricity bills directly?

Renters sometimes miss out because the electricity account is in the landlord's name. The Warm Home Discount goes to whoever holds the electricity account, not to the person living in the property. If your landlord pays the energy bills, the discount would apply to their account, and there's no legal requirement for them to pass it on to you.

That said, if your tenancy agreement includes utility costs, it's worth raising it with your landlord. Some will pass the credit on. Some won't. It's a conversation worth having.

Park home residents and people in certain types of sheltered housing sometimes have their electricity supplied through a site-wide meter, which creates similar complications. The scheme does make some provision for these arrangements, but you'll need to contact your supplier and, in some cases, the site owner to work out whether anything can be done.

Can you get the Warm Home Discount if you're under 66?

Yes. Age isn't a qualifying criterion on its own. The discount is tied to your benefit status and household circumstances, not to your age. A 55-year-old on Income-related ESA with high energy costs could qualify through the Broader Group. A 70-year-old who isn't on any qualifying benefit wouldn't.

This surprises people. There's an assumption that warm home support is only for pensioners, but the scheme is broader than that. If you or someone you're supporting is on a low income and receiving one of the qualifying means-tested benefits, it's worth checking regardless of age.

What happens if you're switching energy supplier?

The discount is tied to your account at the time it's processed. If you switch supplier during the scheme year, you may miss out, or the discount may follow you, depending on the timing. In general, I'd recommend waiting until after you've received the discount before switching. Check with your new supplier before you complete the switch, and ask your current supplier whether an in-progress discount will still be applied.

The Citizens Advice consumer helpline (0808 223 1133) can give specific guidance if you're mid-switch and worried about losing the discount.
