Start with the outcome you need
A regulator, enforcement body and redress scheme may look at the same conduct for different reasons. This profile separates the wider public-interest role from the route that can deal with your own loss.
Role and remit
What Ofgem does
Ofgem regulates Great Britain's gas and electricity markets. It sets licence conditions, monitors suppliers and network companies, protects consumers and can take regulatory enforcement action.
Ofgem sets the framework and acts on systemic or licence compliance issues.
Raise an individual complaint with the energy supplier or network company.
The Energy Ombudsman can investigate qualifying unresolved individual disputes.
Powers and limits
What it can and cannot do
The correct route depends on whether you want wider enforcement, an individual remedy, or both.

Individual route
Supplier complaint, then Energy Ombudsman
The individual dispute route begins with the supplier or network company, not with Ofgem.
- Send a clear complaint to the supplier or network company, including account details, disputed readings, bills and the remedy sought.
- Keep the complaint start date and every response.
- Ask for a deadlock letter if the organisation says it can do no more.
- Refer to the Energy Ombudsman after deadlock or when the current waiting period is met.
- Report wider or repeated regulatory concerns to Ofgem separately where useful.
Ofgem regulates the market. The Energy Ombudsman considers eligible individual complaints. Sending the same evidence to the wrong body can delay the route that can actually award a remedy.
Prepare the report
What to keep and send
Give the body enough information to identify the conduct and understand why it matters. Keep the material needed for your separate claim as well.
- Bills, meter readings, photographs, smart-meter data and tariff terms.
- A calculation of the disputed amount and the correction requested.
- The original complaint, complaint reference and final or deadlock response.
- Records of vulnerability needs or reasonable communication adjustments.
- Evidence suggesting that the issue affects other customers, for any Ofgem report.
Route check
Is this the right route?
Ofgem regulates gas and electricity markets in Great Britain. It sets and enforces the framework for licensed firms, while suppliers and network companies handle complaints first and the Energy Ombudsman considers eligible unresolved individual disputes. Northern Ireland has a different regulatory and redress structure.
| Situation | Best first route | How to separate the issues |
|---|---|---|
| A bill uses an implausible reading | Supplier complaint, then Energy Ombudsman | Provide dated actual readings, photographs and the calculation you believe is correct. Ask for the account to be placed on hold while the dispute is examined where appropriate. |
| A supplier repeatedly mishandles vulnerable customers | Supplier complaint, ombudsman route and possible Ofgem intelligence | Record requested adjustments, priority-service needs and each failure. Separate the personal remedy from evidence of a wider compliance problem. |
| A complaint has reached deadlock | Energy Ombudsman | Use the final response or deadlock letter and check the scheme's current eligibility and referral time limits. |
| A whole supplier practice may breach licence obligations | Ofgem intelligence | Explain the regulated business, conduct, dates, scale and supporting material. Do not assume Ofgem will take over the individual account dispute. |
| The issue concerns Northern Ireland | Utility Regulator and Consumer Council routes | Ofgem's Great Britain remit should not be presented as UK-wide. Use the Northern Ireland bodies and scheme rules. |
Define the outcome before choosing the body
A report can seek wider enforcement, an individual complaint can seek a practical remedy, and a court claim can seek a legally enforceable order. The same evidence may support all three, but each submission should say what that recipient is being asked to do.
Worked situations
How the route works in practice
These examples show how to divide one set of facts into the correct complaint, regulatory and redress tracks. They are illustrations, not findings that a rule has been breached.
Estimated bill after actual readings
A customer supplies readings but receives a large estimated bill. Build a table of reading dates, values, meter serial numbers, billed readings and payments. Ask the supplier to explain the calculation and correct the account. If unresolved after the supplier process, use the current Energy Ombudsman route. A general Ofgem report is not a substitute for that case file.
Direct debit increased without a clear explanation
The useful complaint separates annual consumption, tariff, account balance and payment-plan assumptions. Ask for the calculation and a proportionate review, rather than stating only that the increase feels unfair. Keep prior statements and communications. If the supplier's final response does not resolve it, the ombudsman can consider an eligible complaint within its rules.
Repeated failures affecting a vulnerable household
Record the support need, what the supplier knew, adjustments requested, disconnection or self-disconnection risk and practical impact. Ask for urgent safeguarding support where needed. The supplier complaint can seek account correction and service remedies; ombudsman and regulatory information may address different parts of the same evidence.
Build the case
Prepare one evidence pack, then tailor each submission
A large unstructured upload makes a complaint harder to assess. Build a reliable master file, then send the documents and explanation relevant to the recipient's role.
- Write a five-line case summary. Name the respondent, transaction or service, disputed conduct, date range, current position and outcome needed.
- Build a chronology. List the important event, who acted, the evidence reference and why it matters. Leave out repeated chasers unless delay itself is an issue.
- Separate facts from conclusions. State what the document shows before stating the rule or standard you think it engages. Avoid claiming criminality, fraud or systemic misconduct without a proper basis.
- Create an evidence index. Use short labels such as A1 contract, A2 advert, A3 payment and A4 complaint response. Redact irrelevant personal data, but keep an unredacted original.
- Calculate the personal remedy. Show the refund, correction, reimbursement or compensation requested and how each amount was calculated. This belongs in the redress submission even where the regulator cannot award it.
- Explain the wider concern. For a report to Ofgem, identify the repeated practice, safety issue, regulated standard or public impact. Give evidence of scale without speculation.
- Record every deadline. Keep complaint, chargeback, statutory, ADR, ombudsman and court dates in one list. A regulatory report rarely stops another clock.
| Document | Purpose | Keep it usable |
|---|---|---|
| Case summary | Lets the reader understand the dispute before opening attachments. | Keep it factual, dated and under one page. |
| Chronology | Shows sequence, delay and opportunities to put matters right. | Reference the supporting evidence beside each important event. |
| Issue schedule | Separates different allegations, responses and remedies. | Use one row per issue and do not merge unrelated failures. |
| Loss schedule | Explains the money or practical correction requested. | Show arithmetic, receipts, mitigation and amounts already repaid. |
| Source note | Connects the facts to the rule, Code or official guidance. | Cite the exact provision or heading and check its date and scope. |
Write the submission
A clear structure for the complaint or report
Use plain language and adapt the request to the body's actual powers. A useful submission can be firm without treating an allegation as an established fact.
Suggested structure
Subject: Complaint or information about [respondent] concerning [issue] on [date or period]
Summary: I am writing because [brief factual description]. The attached chronology and documents identify the relevant events.
Issues: My main concerns are [numbered issue 1], [issue 2] and [issue 3]. For each issue I have identified the evidence and the rule or standard I believe may be relevant.
Impact and scale: The effect on me was [practical or financial impact]. I believe the wider concern may be [supported explanation], based on [evidence].
Request: Please confirm whether this is within your remit, what further information is required and what I should expect next. My separate request to [trader, provider or scheme] is [personal remedy].
Do not copy this structure blindly. Remove paragraphs that do not apply, use the body's form where required and comply with limits on issues, attachments or file types. Never include bank details, identity documents or third-party records unless they are necessary and the submission route is secure.
Scope and jurisdiction
Check coverage before arguing the merits
A strong complaint can still fail if Ofgem has no power over the respondent, activity, territory or date. Record the jurisdiction analysis at the front of the file so it can be corrected early.
| Check | Evidence | Why it matters |
|---|---|---|
| Respondent | Legal name, trading name, registration, licence, membership or provider status. | A brand, agent or marketplace may not be the body legally responsible or within scope. |
| Activity | Contract, advert, account, product, service and the precise conduct complained about. | A body can regulate one activity of a firm while another activity belongs elsewhere. |
| Consumer status | Whether the complainant acted mainly outside a trade or profession, or meets another scheme definition. | Individuals, businesses, charities, tenants and passengers may have different access tests. |
| Territory | Consumer location, business establishment, property, service and place of the relevant event. | UK bodies often have England-only, Great Britain or otherwise limited jurisdiction. |
| Date | Event, contract, complaint and final response dates. | Law, rulebooks, membership and regulatory powers change. The current rule may not govern an older event. |
| Complaint stage | Original complaint, escalation, final response, deadlock letter and elapsed period. | Some redress routes open only after the provider has had a fair opportunity to respond. |
If coverage is unclear
Check the official remit and definitions first. Ask the body a short jurisdiction question if necessary, giving the respondent, activity, territory and date. Do not send the full merits bundle merely to ask whether the route exists. At the same time, preserve any alternative complaint, payment, appeal or court deadline.
Agents, groups and marketplaces
Identify who made the promise, received the money, supplied the service, processed the payment and issued the disputed decision. These may be different organisations. A regulator may supervise one of them while the consumer claim lies against another. Keep the contractual and regulatory relationships separate in the issue schedule.
How evidence is assessed
Quality matters more than volume
Regulators and redress bodies apply different legal tests, policies and priorities, but reliable evidence has common features. It is authentic, relevant, complete enough for context and clearly connected to the proposition it is said to support.
Contemporaneous records
Documents created at the time usually carry more weight than a later recollection. Keep original emails, messages, bills, recordings where lawful, photographs with dates, website captures and account history. If a record has been annotated or cropped, retain the original and explain the edit.
Conflicting accounts
Do not hide evidence that appears inconsistent with the complaint. Identify the conflict and explain why one account should be preferred, using timing, independent records, internal consistency and surrounding conduct. A candid explanation is stronger than an incomplete bundle that the respondent can discredit.
Pattern evidence
For wider enforcement, show repeated wording, standard terms, common design, multiple dated examples or a documented failure of systems. Public reviews can suggest a line of enquiry, but anonymous posts are not a substitute for primary evidence. Avoid contacting strangers for personal information or coordinating accounts.
Impact and remedy evidence
Link financial loss to receipts, statements and calculations. Explain non-financial impact with specific duration, disruption, vulnerability or missed opportunities, without turning ordinary frustration into a medical or legal conclusion. Show steps taken to reduce avoidable loss.
Evidence obtained later
New documents can be supplied if they materially affect the issues. State when they were obtained, why they were unavailable earlier and exactly which part of the case they support. Do not repeatedly expand the complaint with unrelated concerns after the respondent has answered the defined issues.
Deadlines and risk
Do not let one route quietly close another
Complaint systems, ombudsmen, payment providers and courts calculate time in different ways. Record each possible deadline from the event that triggers it and verify it with the current official source.
| Clock | Risk to manage | Practical action |
|---|---|---|
| Provider complaint | Internal policies may impose stages or submission periods. | Complain promptly and save proof of receipt, while checking whether a policy limit is legally decisive. |
| Ombudsman or ADR | A final response can start a referral period, and waiting rules do not always extend the final limit. | Record the final response date and submit a complete enough referral before expiry. |
| Payment protection | Chargeback and platform protections can have short contractual limits. | Contact the provider early and ask for the applicable rule and evidence requirements. |
| Statutory appeal or review | Some public-law and tribunal routes use very short, strict periods. | Obtain specialist advice promptly and do not assume a complaint pauses the appeal clock. |
| Court limitation | Negotiation, regulatory reporting or ombudsman review may not stop time running. | Identify the cause of action, jurisdiction and limitation position. Seek advice before relying on an extension or standstill. |
Urgency is not only a date
Loss of essential supply, unsafe products, threatened eviction, fraud in progress, serious vulnerability and imminent travel can require immediate protective action. Use emergency or specialist channels first, then return to the ordinary complaint record when the immediate risk is controlled.
After submission
What may happen next
The absence of a full investigation or personal update does not decide the merits of the private complaint. Track the report and the redress process as separate pieces of work.
Supplier correction
A clear complaint may produce rebilling, account correction, a payment plan, an apology or compensation under the supplier's process.
Ombudsman remedy
For an eligible unresolved case, the Energy Ombudsman may require practical action within its powers. Check current scheme rules rather than assuming every energy issue is covered.
Regulatory action
Ofgem may monitor, investigate or enforce compliance by regulated firms. That work protects the market and may not generate a personal decision or update.
Urgent support
Loss of supply, vulnerability, meter safety and affordability can require faster support than the ordinary complaint timetable. Use the supplier's emergency contacts and current official advice.
Maintain a route log
Record the date submitted, reference number, acknowledgement, promised response date and any request for information. If new evidence arrives, send only what materially changes the assessment and identify the original reference. Repeatedly resending the whole file can obscure the important update.
Keep the personal claim active
Continue reasonable mitigation, answer relevant questions from the business and move to the next redress stage when eligible. If the dispute may go to court, comply with the appropriate pre-action conduct and obtain advice where the value, complexity or risk justifies it.
Detailed questions
Common questions about Ofgem
Always check the linked official source for current forms, jurisdiction, service standards and scheme rules.
Is Ofgem the same as the Energy Ombudsman?
No. Ofgem is the regulator. The Energy Ombudsman is the principal individual redress route for eligible unresolved energy complaints in Great Britain.
How long must I wait before going to the ombudsman?
Use a deadlock letter or the scheme's current waiting rule. Verify the period on the official site because processes can change.
Can I stop paying while a bill is disputed?
Do not assume that a complaint suspends all payment duties. Ask the supplier what amount remains undisputed and seek advice before withholding payment.
What if I cannot afford the bill?
Tell the supplier promptly and use current energy debt and vulnerability advice. Affordability support can run alongside a dispute about accuracy.
Does Ofgem regulate heating networks?
Coverage and protections depend on the activity and current regulatory framework. Check the official source for the service and date rather than assuming ordinary gas or electricity rules apply.
