About This Letter

When a complaint has gone unresolved through normal customer service channels, a formal written complaint escalated to senior management is often the most effective next step. A formal complaint letter signals that you are serious, that you understand your rights, and that you are prepared to involve the relevant ombudsman or regulatory body if necessary.

Formal complaints carry more weight than phone calls or emails to customer service teams. They create a written record, trigger internal escalation procedures, and when they reference the relevant consumer protection legislation and ombudsman powers, demonstrate that you know the consequences of continued inaction. Many regulated companies are required by their regulator to have a formal complaints process, and a posted letter is what triggers it.

PostRight generates a professionally worded formal complaint letter tailored to your situation, citing the Consumer Rights Act 2015 and the relevant ombudsman or regulator for your sector. Your letter is printed and posted via Royal Mail. Once a company receives a formal written complaint, they are on an 8-week clock. If they fail to resolve your complaint within 8 weeks, you are entitled to escalate to the relevant ombudsman, such as the Financial Ombudsman, the Energy Ombudsman, or the Telecommunications Ombudsman. That clock does not start until they receive your formal complaint.
