Generate My Claim LetterEnergy switch evidence
Energy switch disputes often depend on the date the switch was requested, meter readings, tariff promises, supplier emails, billing records and whether either supplier caused delay or confusion.
Switch confirmations, final bills, account numbers and supplier messages can help show where the process broke down.
Opening readings, closing readings, smart meter screenshots and estimated bills can be used to challenge incorrect charges.
A structured complaint letter can set out the timeline and request correction, refund, compensation or a final response.
Quaerens can help you prepare a clear free complaint letter so the supplier can see the issue, evidence and requested outcome.
