Why your Warm Home Discount letter matters this week
A Warm Home Discount letter is one of the few bits of post worth opening with a smile. It’s the government telling you that £150 is coming off your electricity bill this winter. The catch, as MoneySavingExpert warned on 22 October 2026, is that scammers know those letters are landing too, and they’re not above copying them.
So here’s the plain version. Who gets a Warm Home Discount letter, what a real one asks you to do (very little), and the four checks that sort the genuine article from a fake. Doing nothing is usually fine here. Doing the wrong thing, like clicking a link in a text, is where it goes wrong.
Who gets a Warm Home Discount letter?
You get a Warm Home Discount letter if the government has matched you to the scheme using your benefits and electricity account data. The rules differ by nation, so here’s the short version from GOV.UK and MSE, checked October 2026.
| Where you live | Who qualifies | Do you get a letter? |
|---|---|---|
| England and Wales | Named on the electricity bill on 23 August 2026 and getting Housing Benefit, income related ESA, Pension Credit or Universal Credit on that date | Yes, between October and early January 2027 |
| Scotland (core group) | Named on the bill on 23 August 2026 and on Pension Credit, or certain Universal Credit, ESA or Support for Mortgage Interest cases | Yes, October 2026 to January 2027, and the discount is automatic |
| Scotland (broader group) | Named on the bill on 23 August 2026 and on a means tested benefit | No letter. You apply through your energy supplier |
| Northern Ireland | No equivalent scheme | No. Any Warm Home Discount letter there is a scam |
The discount itself is a one off £150 taken off your electricity bill, or your gas bill in some cases if the same supplier provides both. It’s never paid to you as cash, and it doesn’t affect your Cold Weather Payment or Winter Fuel Payment. The full rules are on the GOV.UK Warm Home Discount page.
How can I tell if my Warm Home Discount letter is genuine?
A genuine Warm Home Discount letter arrives on paper, through your letterbox, and most of them ask you to do nothing at all. That’s the single biggest tell. Here are the four checks MSE sets out.
The four checks
- It came in the post. The government only sends a physical letter. An email, text or phone call claiming to be the government about your Warm Home Discount is a scam.
- It doesn’t ask you to click. If your letter says you automatically qualify, you don’t need to click a link, call a number or send any evidence. Anyone asking is a scammer.
- If it asks for information, it gives you a code. Some people are flagged as “potentially eligible” and asked to call a specific helpline with a reference code unique to them. The call agent will never ask for your bank details.
- You can verify the code yourself. Call the general Warm Home Discount helpline on 0800 030 9322 and ask them to confirm your reference number before you do anything else.
MSE says it has asked the government to publish the specific helpline number used in the “more information” letters, so people can check it, and the government has so far declined. That’s why the general number above is the safe route. If you aren’t sure, ring it.
What should I do if I get a text or email instead?
Treat it as a scam, don’t click, and find your supplier’s details yourself. Some energy suppliers do send emails or texts to remind customers the scheme exists, but MSE’s advice is firm: don’t follow any link or number in the message. Look up your supplier’s contact details from your bill or its website and get in touch that way if you want to check.
The reason is simple. A fake Warm Home Discount letter or message is designed to harvest your bank details or get you to pay a “processing fee”. The real scheme has no fee, no form to fill in on a website, and no reason to ask for your card. Your supplier simply takes £150 off the bill.
What if my Warm Home Discount letter never arrives?
Wait until early January 2027, then call the helpline. Letters go out in batches from October through to early January, so a quiet doormat in November doesn’t mean you’ve missed out. If you think you qualify in England or Wales and nothing has arrived by early January, ring 0800 030 9322.
In Scotland, the broader group doesn’t get a letter at all. You apply through your supplier, and the sooner the better, because supplier schemes can close once their allocation is used. Check your supplier’s website for its Warm Home Discount page.
If you’re on a prepayment or pay as you go meter you still qualify. Your supplier will tell you how you get the £150, often as a voucher to top up with. And if you live in a park home, there’s a separate Park Homes Warm Home Discount route on GOV.UK.
While the letter’s on the table, check the rest of your bill
Here’s the Do Nothing Default at work. The £150 is welcome, but it’s a one off against a bill that Ofgem’s price cap put up by 4% from 1 October 2026. If you’ve not looked at your tariff since the spring, that’s the bigger number sitting quietly in the background.
Our guide to the Warm Home Discount in 2026 covers the full eligibility rules, and our energy bill schemes checklist lists the other support worth a look this winter. If you’re older, disabled or rely on medical equipment, the Priority Services Register is free and worth joining before the storms do their worst.
Then compare. A fixed deal won’t suit everyone, and any saving depends on your usage, but it takes about a minute to see what’s on offer. Roo’s already done the boring bit.
Frequently asked questions about the Warm Home Discount letter
- Do I have to reply to my Warm Home Discount letter?
- Usually no. If the letter says you automatically qualify, the £150 is applied to your bill without you doing anything. Only the “potentially eligible” letters ask you to call, and they include a unique code.
- Will the government ever email or text me about the Warm Home Discount?
- No. The government only sends a paper letter. An email, text or call claiming to be the government about the discount is a scam, according to MSE’s 22 October 2026 warning.
- When will the £150 come off my bill?
- Letters go out between October 2026 and early January 2027, and suppliers apply the discount over the winter. The exact timing depends on your supplier, so check with them if nothing shows by the spring.
- What’s the Warm Home Discount helpline number?
- The general helpline is 0800 030 9322. Use it to verify any reference code you’ve been sent, or to chase a missing letter after early January 2027.
- Can I get the Warm Home Discount on a prepayment meter?
- Yes. Your supplier will tell you how it’s paid, often as a top up voucher. The eligibility rules are the same as for credit meters.
