Warm Home Discount 2026/27: Does Solar Affect It?

The Warm Home Discount reopens this October for winter 2026 to 2027, and it is worth a few minutes of your time if you have solar panels. The scheme is a one-off £150 off your electricity bill, and having panels on the roof neither qualifies you nor rules you out. Here is how it works, who gets it, and what it means for a household that already generates some of its own power.

What the Warm Home Discount is

The amount. GOV.UK describes it as a one-off discount of £150 on your electricity bill for the winter. Your supplier applies it to your account; you do not receive the money directly (GOV.UK).

Timing. The scheme is closed until October 2026, when it reopens for winter 2026 to 2027. GOV.UK says most eligible households get it automatically, so there is usually nothing to apply for in England and Wales.

Gas and prepayment. If your supplier provides both gas and electricity, you may be able to have the discount on your gas bill instead. Prepayment customers can still qualify, and the supplier explains how the credit reaches you, for example through a top-up voucher.

Where it applies. It is not available in Northern Ireland. It also does not affect Cold Weather Payment or Winter Fuel Payment.

Who is eligible in England and Wales

GOV.UK sets out the core group for winter 2026 to 2027. You may be eligible if all of the following applied on 23 August 2026:

• your energy supplier takes part in the scheme;
• you, or your partner, receive a qualifying means-tested benefit; and
• your name, or your partner's, is on the electricity bill.

The qualifying benefits listed are Universal Credit, Housing Benefit, income-related Employment and Support Allowance, and Pension Credit (GOV.UK, England and Wales). Scotland has its own rules: some benefits qualify automatically and others require you to apply to your supplier (GOV.UK, Scotland). Check the official page for the full list, because the rules differ by nation.

Do solar panels affect Warm Home Discount eligibility?

Not on the criteria GOV.UK publishes. Eligibility turns on your benefits, your supplier and whose name is on the electricity bill. Owning panels is not listed as a condition either way. A household on a qualifying benefit that also has solar is assessed the same way as one without.

Your supplier still has to take part. This is the catch for solar owners who chose a supplier mainly for its export rate. If you moved to a small supplier because of a good solar export payment, check that it is on the scheme's list. If it is not, the discount will not arrive. Confirm before the qualifying date rather than after, and look at tariffs for solar owners before switching in winter.

The bill it comes off. The £150 is a credit against your electricity account, so it reduces what you owe the supplier. How it interacts with export payments depends on how your supplier runs the account; ask them whether the credit shows on the import side of your statement.

How it fits with the rest of your winter bill

Winter is when solar helps least (see how panels perform in winter). The discount is a modest offset against that. It sits alongside, not instead of, the other levers: a fixed or time-of-use tariff, shifting use into cheap periods, and the changes to VAT on electricity bills.

If you are on a low income and thinking about longer-term upgrades, the Warm Homes Plan is the route to look at next; our Warm Homes Plan guide explains what is on offer.

What to do now

1. Check the GOV.UK page for your nation and read the core-group conditions.
2. Confirm your supplier takes part and that your name is on the electricity bill.
3. Watch for a letter or email from your supplier or the government over the autumn and winter, and check the sender is genuine before acting.
4. If you are in Scotland and your benefit is not automatic, apply directly to your supplier.
5. If your household did not get the discount last winter, GOV.UK has a separate page on what to do.

A note on scams. Because the discount is applied to your bill and usually arrives automatically, be wary of anyone who asks for bank details or a fee to "release" it. If in doubt, contact your supplier using the number on your bill.
