What If I Disagree With an Energy Ombudsman Decision?

People use “appeal” to mean several different routes. This page separates review, rejection, final decision, court options and supplier remedy failure so you do not send the wrong response.

The short answer

If you disagree, first identify what kind of disagreement you have. A material factual error, new important evidence, rejection of the outcome and a supplier failing to implement an accepted remedy are different situations and need different wording.

Decision tree

Your situationDo this firstWhy
The decision uses a wrong date, reading or bill amountWrite a short review request pointing to the exact evidence.This is a factual correction issue.
You have important evidence that was not consideredExplain why it is new or was unavailable before.Do not just re-argue the same point.
You do not want to accept the outcomeCheck whether the decision is proposed, accepted or final.The route depends on decision stage.
The supplier has not completed the remedyUse a remedy follow-up, not a new broad complaint.The issue is implementation.
The Ombudsman cannot deal with the complaintCheck scope and whether another route is relevant.Some issues may be outside the energy Ombudsman route.

Short review request wording

Subject: Request to review Energy Ombudsman decision reference [reference]
I am asking for a review because I believe the decision contains a material factual error or missed evidence.
The specific point is: [one clear point].
The evidence is: [bill / meter photo / supplier email / statement date].
The correction I am asking you to consider is: [exact correction].
I am not adding a new complaint. I am asking for this specific point to be checked against the evidence already supplied.
Do not send a long emotional response if the problem is one factual error. Make the error easy to verify.

Frequently asked questions

Is disagreeing the same as appealing?

Not always. Many users say appeal when they actually mean review, rejection, court route or remedy enforcement.

Should I send all my evidence again?

Usually send only the evidence that proves the specific error you are raising, unless asked for more.

Can the supplier appeal too?

The supplier’s route depends on the process stage and whether a decision has been accepted or made final. Keep the focus on your own response deadline and evidence.
