Warm Home Discount vs the Warm Homes Loan

In brief

The Warm Home Discount is a £150 rebate on the electricity bill of a lower-income household. The Warm Homes Loan is reduced-rate borrowing for a five-figure low-carbon retrofit.
They are run, funded and applied for separately. The discount usually lands automatically through your supplier; the loan comes from an approved lender.
The loan pays for heat pumps and solar, to caps like £20,000 and £15,000. The discount pays for nothing physical; it just cuts one bill.

The warm home discount vs warm homes loan mix-up happens because the names rhyme and the meanings do not. The Warm Home Discount is a £150 one-off rebate taken off the electricity bill of a lower-income household each winter. The Warm Homes Loan is reduced-rate borrowing, usually five figures, for a low-carbon upgrade like a heat pump or solar. One helps you pay this winter's bill. The other helps you replace the thing that runs the bill up. Different schemes, different money, different front doors.

Read that twice if you need to, because getting it wrong costs you either a rebate or a retrofit. Below is who each scheme is for, how you actually get it, and why the two never meet.

Same three words, two unrelated schemes

The overlap is only in the branding. "Warm Home" and "Warm Homes" both sit under the government's push to cut household energy use, so the phrasing keeps colliding in search results. That is where the resemblance ends.

The Warm Home Discount is old, established and about affordability now. It is a rebate that a lower-income household receives on its electricity account, delivered by energy suppliers under rules set by GOV.UK. The Warm Homes Loan is new and about capital works: it lends you money to install low-carbon kit, at a rate the government has helped bring down. One is welfare support on a bill. The other is a financing product for a building job. If you were sent here looking for help with a bill, the loan is not it, and the guide to the Warm Homes Loan Scheme will tell you the same.

What the Warm Home Discount is

The Warm Home Discount gives eligible households £150 off their electricity bill. It is not cash in hand and it is not a cheque. Your electricity supplier applies the rebate to your account, usually over the colder months, and most people who qualify get it without lifting a finger.

Eligibility, per GOV.UK, turns on the Guarantee Credit element of Pension Credit, or being on a low income. If you receive that part of Pension Credit, the rebate is normally applied automatically. Households on a low income who meet their supplier's criteria may need to be identified through data matching, and in Scotland a low-income applicant may have to contact the supplier directly. The scheme runs in winter cycles and is set to reopen for the October 2026 season. None of this involves a loan, a survey, an installer or a heat pump.

What the Warm Homes Loan is

The Warm Homes Loan does the opposite job. It does not touch your bill directly. It lends you money to install a low-carbon measure, at a reduced rate, and you pay that money back over a 3 to 10 year terms. The government pays the lender a grant of up to 20% of the loan, which is what pulls the rate down by up to around 5 percentage points.

Each measure has its own loan cap: an air source heat pump up to £20,000, a ground or water source heat pump up to £35,000, and solar or battery to £15,000 each. Public loans are expected from September 2026, and you apply to an approved lender rather than to the government. For a heat pump you can take the £7,500 Boiler Upgrade Scheme grant first and borrow the balance. There is more detail in our heat pumps guide.

The two schemes side by side

Who it is for	Lower-income households, Pension Credit	Owner-occupiers and private landlords
Income test	Yes, it is means-based	No income threshold, but affordability checks
What it pays for	Nothing physical, just the bill	Heat pumps, solar, battery, biomass
How you get it	Usually automatic via your supplier	Apply to an approved lender
When	Reopens October 2026	Public loans from September 2026

Read down the columns and the point makes itself. One row is a welfare rebate that arrives on its own. The other is a building project you choose to finance. There is no version of the Warm Home Discount that pays for a heat pump, and no version of the Warm Homes Loan that credits your electricity account.

Which one do you actually need

Work back from the problem. If the trouble is this winter's bill and money is tight, the Warm Home Discount is the scheme to check, and a low-income household on Pension Credit is exactly who it is built for. If the goal is a warmer, lower-carbon home and you can carry a monthly repayment, the Warm Homes Loan is the door.

A lot of people who land on the loan pages were actually hunting for insulation help or a bill rebate, and that is a third confusion worth naming. Insulation sits under the Warm Homes: Local Grant, a means-tested grant, not the loan. The loan funds low-carbon measures, the Local Grant funds insulation for lower-income homes, and the Warm Home Discount funds a bill rebate. Three schemes, three jobs. Our explainer on the warm homes plan for 2026 lays out how the umbrella fits together if you want the wider map.

Common questions

Is the Warm Home Discount part of the Warm Homes Loan?

No. The Warm Home Discount is a £150 rebate taken off the electricity bill of a lower-income household, run by energy suppliers. The Warm Homes Loan is reduced-rate borrowing for a low-carbon retrofit, arranged through an approved lender. They share three words in their names and nothing in how they work.

Can I get both the Warm Home Discount and a Warm Homes Loan?

Yes, in principle. They test different things. The discount looks at your income and benefits and cuts one winter bill. The loan looks at whether you can afford to borrow for a heat pump or solar. A household that qualifies for one may or may not qualify for the other, and neither blocks the other.

How do I know which scheme I qualify for?

Start from what you want. If you need help with this winter's electricity bill and you are on a low income or Pension Credit, look at the Warm Home Discount. If you want to install a heat pump or solar and spread the cost, look at the Warm Homes Loan. The funding wizard sorts this in a couple of minutes.

Does the Warm Homes Loan reduce my energy bills like the discount?

Not directly, and not the same way. The discount takes £150 straight off one bill. The loan pays for kit like a heat pump or solar that can lower your running costs over years, but you repay the borrowing meanwhile. One is an instant rebate, the other is an investment with a monthly repayment attached.

Pick the scheme by the outcome you are chasing, not the name that looks familiar. A rebate on a bill and a loan for a retrofit sit in different parts of the system and never overlap. If you are still not certain which side of the line you are on, the funding wizard asks a few questions and points you at the right one.
