New Warm Home Discount Regulations were consulted on earlier this year and approved by Parliament in July. They extend the scheme until winter 2020-21.
The Department for Work and Pensions engage with participating energy suppliers to match the name and address details of recipients of Pension Credit Guarantee Credit and will write to them, either confirming that the discount will be paid automatically, or explaining that they need to verify their details with the Warm Home Discount helpline.
Notice is also provided to the public through GOV.UK, the website for the UK Government. In addition, participating energy suppliers notify their customers on their websites and some also choose to write to them.
