A complaint letter to your housing association needs five things: a clear subject, dates, what the landlord has not done, what you want, and a deadline. Step by step with a free letter builder.
On this page
Short answer: a formal complaint letter to your housing association needs five things. A clear subject line. A dated timeline of what happened. Exactly what the landlord failed to do. Exactly what you want done. And a fair deadline. Sending it in writing, email or portal rather than a phone call, starts the landlord's published Stage 1 complaints clock.
Our free letter builder produces a clean, dated letter that does all of this in two minutes.
Why a letter, and not just a phone call
The mistake tenants make most is leaning on phone calls. Calls are not records. Even when the landlord logs them, no copy reaches you, and "you didn't tell us" is the easiest defence in the world.
A written complaint:
- Starts the formal clock. Most complaints policies give Stage 1 a 10-working-day response window. The clock starts at your written complaint, never at a phone call.
- Creates evidence. The proof environmental health, or any future disrepair claim, will need.
- Forces a written reply. Which becomes more evidence in turn.
- Cannot be misheard or mis-logged. Your wording stands.
The five things every complaint letter needs
1. A clear subject line
"Formal Stage 1 complaint, [your address], damp and mould unresolved since [date]"
Not "Hi, complaint about my flat."
2. A dated chronology
A bullet list of every contact about the issue, dated, with reference numbers where you hold them. Example:
- 12 February 2025, first reported damp on bedroom wall by phone, reference DRP-12345
- 27 February 2025, contractor visited, took photos, no follow-up
- 14 March 2025, re-reported via portal, reference DRP-12389
- 6 April 2025, chased by email, no response
This one section works harder than any other part of the letter.
3. What the landlord has failed to do
Name the specific duty they missed. No lawyer needed; short references land fine:
- "Failed to investigate inside the timescale in your published repairs policy."
- "Breach of Section 11 of the Landlord and Tenant Act 1985: the structure of the home was not kept in repair."
- "Breach of the Homes (Fitness for Human Habitation) Act 2018: the home is not fit, because mould keeps hold of two rooms."
- "Failure to act on a prescribed hazard inside the timescale set by Awaab's Law, in force 27 October 2025."
4. What you want them to do
Be specific. "Sort it out" gives them nothing to act on. Try:
- "Carry out a full inspection of the damp and mould and find the underlying cause."
- "Complete the safety work inside the Awaab's Law window for significant hazards: 5 working days from the investigation ending."
- "Treat the affected wall surfaces with proper mould treatment."
- "Give a written response inside the Stage 1 timescale in your published complaints policy."
- "Pay fair compensation for [period] during which the home has not been fit."
5. A deadline
"Please respond within [10 working days, in line with your Stage 1 complaints timescale]. If no response or clear plan of action reaches me by [date], I will escalate to Stage 2 and then to the Housing Ombudsman."
Step-by-step template structure
``` [Your name] [Your address] [Your contact email] [Date]
[Housing association complaints team] [Their address or email]
Subject: Formal Stage 1 complaint, [your address], [issue] unresolved since [date]
Dear Complaints Team,
I am writing to make a formal Stage 1 complaint under your published complaints procedure.
The issue [1 to 3 sentence description of the problem.]
Timeline
- [date], [what happened, reference]
- [date], [what happened, reference]
- [date], [what happened, reference]
[…]
Why this is a complaint You have failed to [specific obligation]. This is a breach of [legal/policy reference].
What I want
- [Specific action 1]
- [Specific action 2]
- [Specific action 3]
Deadline Please respond within 10 working days, in line with your Stage 1 complaints timescale. If I have not received a substantive response by [date], I will escalate to Stage 2 and then to the Housing Ombudsman.
[If relevant: Please note that I have flagged vulnerability, [reason], and ask that this be reflected in the priority given.]
Yours faithfully, [Your name] ```
What to attach
- Dated photos of the issue.
- A short video where it helps: running water, visible mould spread.
- A doctor's letter where health suffered.
- Receipts for anything replaced or paid for.
- Copies of earlier reports where you hold them.
Where to send it
Every housing association publishes a complaints contact. Usually that means:
- A dedicated complaints email address
- A complaints form on the website
- A complaints postal address
In doubt? Email the customer services address and the complaints email both, with "FORMAL COMPLAINT" in the subject line. That kills the "we didn't realise it was a complaint" defence.
What happens next
- Stage 1. The landlord must acknowledge inside their published timescale, usually 5 working days, and respond inside the Stage 1 window, usually 10.
- Stage 2. Not satisfied? Request escalation in writing. Stage 2 usually runs 20 working days.
- A disrepair claim. Things still not put right? A compensation claim may stand. Call us free on 0800 030 4669.
