A Complaint Letter is a formal, written notice to a business or individual about issues such as unacceptable behaviour, faulty products, poor service, and more. It outlines exactly what’s causing the problem and what’s needed to remedy the situation. 

A Complaint Letter also creates a record of your attempt to resolve the conflict before taking legal action. 

Often, sending the letter directly to the offending party is enough to fix the problem. But, if you do escalate the problem to higher authorities (e.g., ombudsmen, tribunals, or other government agencies), you’ll have documentation to support your argument. 

In this case, you’ll have proof that the other party is aware of the problem and that you’ve attempted to resolve the issue in other ways.

If there’s a problem that impacts your life, money, health, or ability to work, it’s a good idea to use a Complaint Letter to raise your concerns with the appropriate authority. Doing so shows your commitment to solving the problem. 

For example, situations that commonly warrant a Complaint Letter include:

• Consumer complaints: A company’s service or product fails to meet quality standards (e.g., a faulty car)
• Housing complaints: A neighbour makes too much noise (e.g., a barking dog)
• Human Resources (HR) complaints: A co-worker exhibits inappropriate behaviour at work (e.g., unfair treatment or harassment)
• School complaints: A child runs into a problem with bullying
• Hospital complaints: A patient has a negative care experience with a medical practitioner, hospital staff, or an NHS service
• Privacy complaints: A person experiences a breach in their data protection services (e.g., a landlord shares your personal information to an unauthorised third party)
