Bad housing can cause real clinical harm. Here is what a doctor's letter adds to a housing disrepair claim, and how to ask your doctor for the right kind of letter.
A question we are often asked: does a letter from your doctor actually make a housing disrepair claim stronger?
The answer is yes, and not for the reason most people assume. This article looks at what medical evidence really contributes, and how to ask your doctor for the right kind of letter.
What a doctor's letter adds to a housing disrepair case
There are three distinct things a doctor's letter can do:
1. Establish the causal link
A landlord can argue that mould "might be there" but that there is no proof it is affecting anyone in the household. A letter that says "Patient has presented with three episodes of bronchitis in the past four months consistent with exposure to fungal spores. The patient's home has documented damp and mould, this is the most likely cause" closes that argument.
This is the contribution that most directly increases the value of a claim. Courts weigh medical evidence heavily.
2. Establish vulnerability
Awaab's Law and Section 11 case law both recognise that a vulnerable occupant raises the duty on the landlord. "Vulnerable" is interpreted broadly: children, elderly, pregnant, immunocompromised, asthmatic, anyone with a pre-existing respiratory condition, anyone with a disability that limits their ability to escape or mitigate the hazard.
A letter confirming any of these, particularly if it names the patient, strengthens the urgency category, which can shorten the deadline the landlord is held to.
3. Quantify the harm
For compensation, the question is not just "was there an issue" but "what was the impact on this person, in this home, over this period". A letter listing appointments, prescriptions, missed days of school or work, and ongoing referrals is the evidence used to quantify general damages.
What strengthens a medical letter most
Across the housing-disrepair sector, the patterns are clear and well documented:
- Medical evidence is widely recognised as one of the strongest factors in a disrepair case, alongside the written reporting trail and any delays by the landlord.
- Letters that reference harm to a child (a child with documented respiratory symptoms) tend to support notably higher awards than equivalent cases without.
A medical letter helps most when it:
- Names a specific clinical impact (not just "could be related to housing")
- Is written during the period of exposure, not months later
- References a specific date the patient first mentioned the housing issue
- Is on letterhead with the clinician's registration number
How to ask your doctor
Doctors are time-poor and may not know housing-disrepair processes. The cleanest way to ask:
"I am in a housing disrepair situation (damp, mould, whichever) and the landlord has been ignoring me. I am bringing a legal claim. Could you write a short letter confirming: (1) the symptoms I have presented with that may be related to housing conditions, (2) my relevant medical history including any vulnerabilities, and (3) your clinical opinion on whether housing conditions are a likely contributing factor? It does not need to be long, but it needs to be on letterhead with your registration number."
Some surgeries charge a small fee (£20-£50) for this kind of letter. That is normal, and the cost is typically recoverable as part of your claim.
If your doctor is reluctant, you can also request a copy of your medical record under your right of access (free under UK GDPR). The record itself often contains the relevant evidence without needing a separate letter.
In summary
A doctor's letter is not magic, but it is high-leverage evidence in any housing-disrepair claim. If you have seen a doctor about symptoms that started or worsened around the time of the housing problem, ask for a short letter. Keep it with your photos and your written reports to the landlord.
