Home / Everyday Money / Warm Home Discount Checker
In a nutshell
Plain-English Warm Home Discount checker for England, Wales and Scotland, including Pension Credit, low-income criteria, prepayment meters and what to do…
Support first, switching second.
This checker routes through the main Warm Home Discount pathways: Pension Credit Guarantee Credit, low-income criteria, Scotland supplier rules and prepayment-meter situations.
Use the official GOV.UK page when the scheme opens. If bills are already unaffordable, contact your supplier and ask about hardship support before arrears build.
Important timing
As of 8 May 2026
GOV.UK says the Warm Home Discount Scheme has closed and will reopen in October 2026. This page is designed to prepare the check and route you to the official page, not to replace the scheme rules when it reopens.
