Social Energy Tariff
Households with low income or those receiving social benefits (like unemployment or child benefits) are automatically eligible for the Social Tariff. This provides a discount of over 30% on electricity and gas bills.
The process is automatic via data cross-referencing between Social Security and energy providers. If you believe you are eligible but aren't receiving the discount, you must contact your energy supplier to force a check.
