wrong meter reading used when switching

mustoep

Hi, when switching to Greenstar last year my dad had to ring through with his meter reading as the online facility wasnt working. He then received a very large bill from his old supplier but thought it must be right as he'd had estimates for years, but he's just had a request for a meter reading and found that the current reading is nowhere near the reading Greenstar started billing him from over 6 months ago. He didnt make a note of the reading he gave them but it was clearly either wrong or taken down wrong. What do we do now?
thanks.

You need to contact your current supplier to explain that the opening readings were wrong and give them the current readings.
If there is a big discrepancy they will take it up with the previous supplier to work out what the reading should have been.

There's an explanation here - you're not with Ovo but I would imagine the process is similar.

(And tell your dad to take regular meter readings himself in future and send them in rather than relying on estimated bills.)
