Overview

• The one‑off £150 credit will be applied to eligible electricity accounts or issued as prepayment vouchers between October 2025 and March 2026, with final application due by 31 March 2026.
• DWP letters, arriving October to January, confirm eligibility and whether payment is automatic or requires contacting the official Warm Home Discount helpline before 28 February 2026.
• Officials caution that unsolicited calls asking people to apply are scams, as eligible customers usually receive the credit automatically and should only use contact details provided in the DWP letter or on GOV.UK.
• The expanded scheme now covers just over six million households after adding about 2.7 million, including roughly 900,000 families with children.
• Suppliers with more than 1,000 customers must participate and deliver the credit—major firms such as British Gas, E.ON Next, EDF, OVO, Octopus and ScottishPower are listed—while low‑income households in Scotland may need to apply via their supplier and Northern Ireland operates a different scheme.
