The Warm Home Discount is an annual £140 payment to help those struggling to pay their energy bills. 

Who gets the Warm Home Discount?

Large energy companies must pay the Warm Home Discount. It's an annual credit they pay into the electricity account of those who are eligible. Many smaller energy suppliers also offer it.

For winter 2020-21, the payment was £140. While this is a welcome saving, you should also make sure you're on the cheapest energy tariff for your home. 

The Warm Home Discount applies to two groups:

  • The core group: if you receive the Guarantee Credit element of Pension Credit, you're in this group. In most cases, your energy supplier will identify you automatically and write to you telling you how to get the discount.
  • The broader group: if you are on a low income or get certain means-tested benefits, you might qualify in this group. Each supplier has its own eligibility criteria, which are approved by the regulator Ofgem, so you should check with your supplier to see whether you qualify.

If you're on a standard default tariff with one of the Big Six energy companies, you could save hundreds of pounds by switching. Check our free, independent comparison site, Which? Switch, to find the cheapest energy deal for you.

Is the Warm Home Discount only for pensioners?

No. Energy companies pay the Warm Home Discount to a broader group of people who have difficulty paying energy bills. Gas and electricity suppliers have some discretion over which of their customers make up the broader group and how many to help, based on their market share.

Participating suppliers have had their own eligibility criteria approved by Ofgem and limit the number of customers who can benefit. You might be eligible if you:

  • are on a low income with a disability
  • have a long-term illnesses
  • are a parent with young children
  • get certain means-tested benefits. 

The actual criteria used vary between electricity suppliers. See the government's Warm Home Discount guidance for eligibility criteria for different suppliers.

If your supplier isn't listed, ask it whether it offers the Warm Home Discount before you switch.

How to apply for the Warm Home Discount

Households in the core group should automatically receive the discount on their energy bill without having to take any action. 

You should get a letter confirming this, or telling you how to apply, if necessary. You should receive this letter between October and December 2020. The letter will say if you need to call a helpline to confirm your details. If it does, you should do this by 26 February 2021.

Payments are usually made during the winter months (by the end of March 2021, at the latest).

If you think you qualify in the core group but didn't get a letter, contact the government's Warm Home Discount helpline on 0800 731 0214 (Monday to Friday, 8am to 6pm). 

Customers in the broader group have to apply to their electricity supplier – check with it to find out the eligibility criteria. People with pay-as-you-go meters can also qualify for the discount.

Contact your energy firm as soon as possible if you are in the broader group. The number of discounts it can give is limited.

The Warm Home Discount is applied to your electricity account. So if you receive gas and electricity from different suppliers, you should contact your electricity company to register. But if you get your gas and electricity from the same supplier, you can ask it to credit your gas account instead.

If I switch energy supplier, what happens to my Warm Home Discount?

If you switch away from a supplier that offers the Warm Home Discount to a supplier that doesn't, you'll lose your Warm Home Discount. 

But some of the smaller suppliers could be cheaper for you overall, even when taking into account the value of the Warm Home Discount. So it's worth checking whether you will be better off. 

An independent comparison site, such as our own Which? Switch, will show you how much you could save by switching away from your current supplier and tariff. Check if you're on the cheapest energy deal with Which? Switch.

If you qualify for the Warm Home Discount under the broader group with your current supplier and want to switch to another supplier, check first that you would still qualify under the criteria of your new supplier's broader group. 

Again, take into consideration whether you could be better off by switching even if you were to lose the Warm Home Discount.
