Formal complaint letter to a business, bank, insurer, energy supplier or any organisation. States your complaint, the remedy you are seeking and the deadline to respond. From £4.99.
A Formal Complaint Letter is a written communication to a business, service provider or public body that puts your complaint on the record, states the remedy you are seeking, gives a deadline for response, and warns of escalation if the matter is not resolved. It is the precursor to an ombudsman complaint, a regulator referral or court proceedings — and the document that starts the clock on most formal complaints processes.
When informal contact has not resolved the problem. A formal complaint letter escalates a dispute from casual correspondence to a documented record. For financial services complaints, a formal complaint triggers the 8-week window after which the Financial Ombudsman Service (FOS) has jurisdiction. For legal services complaints, it triggers the Legal Ombudsman's clock. For energy and telecoms, it opens access to the relevant ADR scheme.
The sender's identity and relationship with the recipient, a factual chronology of the complaint, why the conduct or product failure is unacceptable, the specific remedy sought, a firm response deadline (typically 14 days), the escalation route if the matter is not resolved (ombudsman, regulator, Trading Standards or county court), and a scope note confirming the letter states the sender's position and is not legal advice on entitlement.
