If you need to raise a formal Service Complaint about discrimination, harassment or bullying, a written letter is the recommended first step — it creates a clear record and shows you're pursuing the matter formally. Below is what a strong service complaint letter should include, plus a free tool to generate yours.

What this letter needs to cover

What counts as a valid Service Complaint

A Service Complaint is the formal route for raising concerns about how you've been treated in service — this covers issues like bullying, harassment, discrimination, unfair treatment in postings or promotions, and bullying by colleagues or those in the chain of command. It's a structured process with defined stages, not simply a grievance email.

What to include before you send it

Time limits matter

Service Complaints generally need to be raised within a set period of the incident occurring — normally measured in months, not years. Don't delay raising a complaint while you decide exactly how to word it; you can always add further detail once the formal process has started.

Frequently Asked Questions

Will raising a complaint affect my career?
You're protected from victimisation for raising a genuine Service Complaint in good faith. If you experience any negative treatment as a result of raising one, that itself can form the basis of a further complaint.

Can I raise a complaint anonymously?
Formal Service Complaints generally need to be raised in your own name for the process to proceed properly, though you can discuss concerns informally and confidentially with a welfare officer first if you're unsure how to proceed.
