Yes - OneLink Energy covers every gas and electricity provider in the UK, without exception.
This includes customers who:
Top up a prepayment meter - online, at a PayPoint, or at a Post Office
Pay a bill - including by direct debit or standing order. The voucher enables a one-off payment online or by phone to settle a bill or add credit to an account
Use off-grid energy - including heating oil, LPG, and coal suppliers
When you open your OneLink Energy link, you'll be asked to select how you pay for energy. The system will then route you to the right solution for your situation automatically.
