Energy complaints where evidence and timeline matter
The builder helps you organise the facts behind common energy supplier problems so you can understand what happened, prepare the evidence and decide which complaint route may be worth considering.
Delayed switch, erroneous transfer, blocked switch, duplicate accounts or supplier objections.
Estimated bills, wrong readings, back-billing concerns, final bill delay or unexplained debt.
Smart meter faults, prepayment top-ups, wrong meter details, inaccessible readings or metering evidence gaps.
Direct Debit changes, credit balance refund, duplicate payments, debt collection or payment-plan issues.
Understanding Bank Complaints
Banks and FCA-regulated firms must have complaint procedures. Keep statements, messages, transaction references and the final response; this page organises evidence and does not provide legal advice.
Formal complaint
Use the bank's current official complaint route and keep the reference and acknowledgement.
Most complaints
The standard response period is generally eight weeks before a Financial Ombudsman route may be available.
Payment services
Relevant payment-services and e-money complaints generally use 15 business days, not calendar days.
Exceptional extension
A relevant exceptional holding response may extend the payment-services final response period up to 35 business days.
Final response
Keep the decision and the stated Financial Ombudsman rights and deadline.
Financial Ombudsman
The service is free for consumers, is not a court and applies only where jurisdiction and time limits are met.
Specialist routes
Section 75, APP fraud, frozen accounts, car finance and other specialist products remain separate routes.
Safe references
Use masked references or last four digits; do not enter unnecessary full account or card numbers.
Official complaint and Ombudsman guidance
Common questions before choosing a route

Prepare a professional account, payment, charge, closure or complaint-handling file using the shared Framework A workflow.
Important bank complaint boundaries
This general builder does not replace specialist Section 75, APP fraud, Frozen Account, car-finance, investment, pension, mortgage or regulated debt routes.
Seek urgent specialist help for court papers, imminent financial harm or inaccessible essential funds where delay could materially worsen the position.
Before using your Complaint Pack
This builder organises bank-account facts, evidence and a self-service complaint pack. It does not submit complaints automatically or promise refunds, compensation or Financial Ombudsman acceptance.
Review every factual entry against statements, transaction records and correspondence before sending anything to a bank, provider or Ombudsman.
