The short, accurate answer: UK ombudsman schemes do not offer an appeal in the way a court does. There is no second panel that rehears the merits of your case because you disagree with the outcome. What you do have are three real options, and which ones are open depends on where your case is in the process. Before the decision becomes final, you can respond to the provisional findings with further evidence, and this is the closest thing to an appeal that exists. Once the decision is final, you can accept it, which usually makes it binding, or reject it, which usually leaves your legal rights intact so you can still take the business to court. The detail varies by scheme, and the differences matter, so this guide takes them in turn.
The stage most people miss: before the decision is final
Almost every scheme decides in two stages. A caseworker or investigator looks at the file first and issues an initial view or provisional findings. Only if one side disagrees does the case go to an ombudsman for a final decision.
That first stage is your genuine opportunity to change the outcome. If the initial view goes against you, you are invited to say why you disagree before the final decision is made. A response that simply repeats the complaint rarely moves anything. A response that addresses the specific reasoning, points to the evidence the investigator did not weigh, and adds any documents that fill the gaps identified, is read as new input rather than protest. If your case is at this stage, put your effort here, because it is the last point at which the merits are still open.
What happens when you accept a final decision
Acceptance is not a formality. In most schemes, accepting the decision within the deadline makes it binding.
At the Financial Ombudsman Service, if you accept the final decision by the date given, it becomes binding on the business, and the business must do what the decision says. Because acceptance settles the complaint, you cannot usually accept the money and then sue for more over the same matter.
At the Energy Ombudsman, acceptance works as full and final settlement of the complaint. The supplier is required to complete the awarded remedy, and the case is closed.
The communications schemes work the same way in substance: accept the decision and the provider must carry it out, and the dispute is settled.
The practical point: read the decision carefully before accepting, because acceptance is the end of the road for that complaint.
What happens if you reject or decline the decision
Rejecting a final decision, or simply not responding by the deadline, normally means the decision does not bind either side. You keep your right to pursue the same dispute in court, most often through the county court small claims process for sums up to 10,000 pounds in England and Wales.
Three cautions before you treat court as the fallback:
- Time limits still run. Court claims are subject to statutory limitation periods, and time spent in the ombudsman process does not necessarily stop the clock. If the events are already some years old, take that into account before rejecting an outcome you could live with.
- The court is not bound to agree with you either. A judge looks at the legal position, not at what feels fair, and an ombudsman decision that went against you on the evidence is a signal worth weighing honestly.
- Costs and effort are real. Small claims are designed for people without lawyers, but they still take months, and larger claims carry cost risk.
Rejecting is the right call when the decision misunderstood the facts, the sum at stake justifies the effort, and your evidence is strong. It is the wrong call when the objection is that the award feels too small for the inconvenience suffered.
Is there any true appeal route?
Before either of the routes below, check the specific scheme’s own rules: some schemes allow a limited internal review of a decision on narrow grounds, such as material new evidence or a clear procedural error, and that is always worth checking first. Beyond that, two narrow routes exist, and both are widely misunderstood.
Judicial review asks the High Court to examine whether the scheme acted lawfully and followed a fair process. It is not a rehearing of the merits, it does not exist because you disagree with the outcome, it is expensive, and it succeeds rarely. For an ordinary consumer dispute it is almost never the answer.
Complaints about service can be made to every scheme about its own handling, for example long delays or lost documents. This can bring an apology or a goodwill payment for poor service, but it does not change the decision itself.
Scheme by scheme: the rules that differ
Financial Ombudsman Service. An investigator gives an initial assessment; either side can ask an ombudsman for a final decision. Accept by the stated date and it binds the business. Reject and your legal rights against the firm remain, subject to limitation. There is no appeal against a final decision.
Energy Ombudsman. Covers gas and electricity suppliers. You normally have a set period to accept the remedy; acceptance is full and final settlement. If you reject it, the supplier is no longer required to carry out the proposed remedy and you keep your legal routes. Our Energy Ombudsman complaint process guide covers the process from the start.
Communications Ombudsman and CISAS. Broadband, phone, mobile and pay TV providers each belong to one of these two schemes. The decision process mirrors the others: respond to provisional findings, then accept or reject the final decision. Note that for complaints raised from 8 April 2026, you can go to the scheme after six weeks rather than eight if the provider has not resolved the complaint, or earlier with a deadlock letter. If you have not started that process yet, see how to write a letter to the Communications Ombudsman.
Water Redress Scheme. Water complaints pass through the Consumer Council for Water before the redress stage; the accept or reject choice at the end works the same way. See how to write a letter to the Water Ombudsman.
For any scheme not listed here, the pattern to check in its terms is the same three questions: how do I respond before the decision is final, what does accepting do, and what does rejecting leave open. Our guide to UK ombudsman schemes explains which scheme covers which sector.
Putting a disagreement in writing
Whether you are responding to provisional findings or setting out why a final decision has not resolved matters, the document does the work. It needs the case reference, the specific findings you dispute, the evidence for each point, and what outcome you are asking for, in that order, without heat. If you would rather have that document prepared professionally, our ombudsman complaint letter service drafts it from your papers, for you to review and send.
