UK complaint letters by sector

Different sectors need different complaint structures. A bank complaint often needs transaction details, dates, account references and escalation language. A retail complaint may need order numbers, refund framing and evidence of the fault. An airline complaint may need flight numbers, delay duration and prior contact history.

Start with the route that best matches who you paid, who made the decision, and what outcome you want. The clearer the route, the easier it is to produce a letter that a company can understand and route internally.

If you cannot find the right company, start with the generator and enter the company name manually. The letter can still be structured around the issue, evidence and outcome you want.
