What Evidence Do You Need to Support a Claim?

Living with damp and mould can affect your comfort, damage personal belongings, and potentially contribute to health problems. If your landlord has failed to address the issue after being notified, you may want to explore your options. Understanding the evidence needed for Damp and mould compensation claims can help you organise your records and explain your situation clearly.

The right evidence can help demonstrate the condition of your home, when you reported the problem, how your landlord responded, and the impact it had on your daily life. Although every case is different, keeping accurate records from the beginning can make it easier to assess whether you have grounds for a claim.

How Housing Repair Solutions Can Help You Understand Your Claim

Gathering evidence can feel overwhelming, particularly when you have repeatedly reported a problem without receiving a satisfactory response. Housing Repair Solutions helps tenants understand housing disrepair claims and the information that may be needed to assess their circumstances.

Before starting a claim, it is useful to organise your evidence and understand what each record can demonstrate. Here are the main types of documentation that may help.

Dated Photographs and Videos of Damp and Mould

Photographs and videos are among the most useful ways to document visible problems in a property. They can show the location, extent, and development of damp or mould over time.

When taking photographs, try to capture:

• 
  

  Mould growing on walls, ceilings, window frames, or other surfaces.

  
  


• 
  

  Damp patches, water stains, peeling wallpaper, or damaged plaster.

  
  


• 
  

  Leaks around windows, pipes, ceilings, or other areas.

  
  


• 
  

  Damage to furniture, clothing, carpets, or other belongings.

  
  


• 
  

  Different affected areas to show the overall condition of the property.

  
  

Take clear photographs in good lighting and keep the original files with their dates. If the problem spreads or returns after cleaning, additional photographs can help document those changes.

Videos may also provide useful context by showing the affected area and surrounding conditions. However, photographs alone may not establish the underlying cause of dampness or prove that a landlord was responsible. A professional inspection may be necessary to investigate the source.

Emails, Letters, and Messages to Your Landlord

One of the most important questions in a housing disrepair case is whether the landlord knew about the problem and had a reasonable opportunity to respond.

Keep copies of emails, letters, text messages, and online maintenance requests that explain the issue. Include any messages sent to a letting agent or property manager where relevant.

Your records should ideally show:

• 
  

  The date you first reported the problem.

  
  


• 
  

  A clear description of the affected areas.

  
  


• 
  

  Any photographs shared with the landlord.

  
  


• 
  

  Requests for inspection or repairs.

  
  


• 
  

  Follow-up messages if the problem remained unresolved.

  
  


• 
  

  Responses, repair appointments, or explanations received.

  
  

If you report a problem by telephone, make a note of the date, time, person you spoke to, and what was discussed. Follow up in writing where possible so you have a clear record.

These documents may help establish a timeline and show how the landlord responded after being notified.

Medical Records and Evidence of Health Effects

Damp and mould can affect indoor air quality and may contribute to respiratory symptoms or worsen existing conditions in some people. If you believe your living conditions have affected your health, relevant medical records may help explain the impact.

Potential evidence includes:

• 
  

  GP appointment records.

  
  


• 
  

  Medical letters or reports.

  
  


• 
  

  Records of specialist consultations.

  
  


• 
  

  Prescriptions or treatment records relevant to the symptoms.

  
  


• 
  

  Documentation of ongoing symptoms and their effect on daily activities.

  
  

Keep the information factual. Explain when symptoms began, when you sought medical advice, and whether the symptoms changed while you were living in the property.

Medical evidence may help support an argument about the impact on your health, but it does not automatically prove that damp or mould caused a particular condition. That connection may require further medical assessment.

Importantly, you should not wait for medical evidence before reporting serious damp and mould or requesting necessary repairs. Health and safety concerns should be addressed promptly.

An Independent Surveyor's Report

Photographs can show what a property looks like, but they may not explain why dampness is occurring. An independent surveyor or suitably qualified professional can investigate the possible cause and recommend appropriate remedial work.

Depending on the property, an inspection may examine:

• 
  

  Roof damage or leaking pipes.

  
  


• 
  

  Defective windows or external walls.

  
  


• 
  

  Poor ventilation or condensation.

  
  


• 
  

  Problems with insulation or heating.

  
  


• 
  

  Structural defects that allow moisture to enter.

  
  


• 
  

  Previous repairs that failed to resolve the issue.

  
  

A report may identify the likely source of the problem, the work required, and the extent of the damage. This can be particularly helpful where the landlord disputes responsibility or suggests that the issue results entirely from the tenant's behaviour.

Not every case requires a privately commissioned report. Consider seeking advice before paying for an inspection, as a legal adviser may be able to explain whether expert evidence is appropriate for your circumstances.

Receipts for Damaged Belongings and Additional Expenses

Damp and mould can damage household possessions and may lead to additional costs. If you are seeking compensation for financial losses, keep evidence showing what you lost and how much it cost.

Useful records may include:

• 
  

  Receipts or invoices for damaged furniture and clothing.

  
  


• 
  

  Purchase records for items that need replacing.

  
  


• 
  

  Photographs of damaged possessions.

  
  


• 
  

  Repair or replacement quotations.

  
  


• 
  

  Receipts for reasonable expenses related to the problem.

  
  


• 
  

  Records of additional costs, such as running equipment to manage persistent dampness.

  
  

If you no longer have the original receipt, look for bank statements, online order histories, or other documents that may help establish the purchase and value.

Create a simple list of affected items, including their approximate purchase dates, original costs, and current condition. Be realistic about the value of older belongings, as compensation is not necessarily based on the full cost of buying everything new.

Tenancy Agreement and Property Records

Your tenancy agreement can help establish the nature of your rental arrangement and identify relevant responsibilities. Other property documents may also help explain the history of the problem.

Keep copies of:

• 
  

  Your tenancy agreement.

  
  


• 
  

  Check-in or inventory reports.

  
  


• 
  

  Property inspection records.

  
  


• 
  

  Previous repair requests.

  
  


• 
  

  Contractor visit records.

  
  


• 
  

  Reports from the local council or an Environmental Health Officer, if applicable.

  
  

These documents may provide context about the property's condition when you moved in and whether the landlord or managing agent was previously aware of defects.

The legal responsibilities involved can vary according to the type of tenancy, the nature of the defect, and the circumstances of the case. A tenancy agreement is useful evidence, but it does not necessarily determine every legal responsibility on its own.

A Timeline of Events

When evidence comes from different sources, it can be difficult to remember the order of events. Creating a timeline is a simple way to organise everything.

For example:

This is only an illustrative example. Record the actual dates and events in your own case.

A timeline can help identify gaps in your records and make it easier to explain how the problem developed. It may also help a legal adviser assess whether the landlord was given appropriate notice and whether the response was reasonable.

Council Reports and Formal Complaints

If the problem remains unresolved, you may be able to raise a formal complaint with the landlord or seek assistance from your local authority, depending on your circumstances.

Keep copies of complaint forms, reference numbers, inspection reports, and written decisions. If an Environmental Health Officer inspects the property, ask how you can obtain a copy of any relevant report.

For tenants of councils or housing associations, the landlord's complaints procedure and the Housing Ombudsman may also be relevant. The appropriate route depends on the type of landlord and the nature of the dispute.

Official inspection findings can help document the condition of the property, although they do not automatically establish entitlement to compensation.

Common Mistakes to Avoid When Collecting Evidence

Even when a problem is serious, missing records can make it more difficult to explain what happened. Avoid these common mistakes:

Waiting too long to take photographs: Document the condition as soon as possible and continue recording significant changes.

Relying only on verbal conversations: Keep written records of reports, responses, and repair appointments.

Throwing away damaged items without documenting them: Photograph the damage and retain receipts or other evidence of value where possible.

Assuming mould alone proves landlord negligence: The cause, the landlord's responsibilities, notice of the problem, and response may all be relevant.

Ignoring health concerns: Seek appropriate medical advice if symptoms develop or worsen, and keep relevant records.

Exaggerating losses: Provide accurate information and distinguish confirmed expenses from estimates.

Waiting for every document before asking for help: You can seek advice while continuing to collect evidence. Do not delay reporting urgent property or health concerns.

Frequently Asked Questions

1. What evidence is needed for a damp and mould compensation claim?

Useful evidence may include dated photographs, written reports to the landlord, responses, repair records, medical documents where relevant, receipts for damaged belongings, and professional inspection reports. The most relevant evidence depends on the circumstances of the case.

2. Can I make a claim if I did not take photographs at the beginning?

Possibly. You can still gather evidence such as emails, messages, repair records, witness statements, receipts, and photographs of the current condition. Explain honestly when the images were taken and avoid suggesting that they show an earlier condition if they do not.

3. Do I need a medical report to make a claim?

Not every housing disrepair claim requires medical evidence. However, if you are claiming that damp and mould affected your health, relevant medical records may help support that part of your case. Medical evidence is not a prerequisite for reporting damp and mould or requesting repairs.

4. What if my landlord says the mould is caused by condensation?

The cause of damp and mould can be complex, and more than one factor may be involved. Keep records of the conditions, your repair requests, and the landlord's response. A qualified professional may be able to investigate the underlying cause and identify any defects that need attention.

5. Can I claim for furniture and clothing damaged by mould?

Depending on the circumstances, damage to personal belongings may be relevant to a compensation claim. Photographs, receipts, purchase records, and reasonable estimates can help demonstrate the loss. Whether compensation is recoverable depends on the evidence and applicable law.

6. How long should I keep evidence of housing disrepair?

Keep relevant documents throughout the dispute and until your case is fully resolved. If you are considering legal action, seek advice promptly about any applicable time limits, as these can vary depending on the type of claim and circumstances.

7. Can I still make a claim if the landlord has repaired the mould?

Potentially. Repairs may resolve the current problem, but they do not necessarily settle questions about earlier disrepair or losses already suffered. Keep your historical evidence and seek advice about whether a claim may be appropriate.

8. What should I do if my landlord ignores my repair requests?

Keep copies of your requests and follow-up messages. You may be able to use the landlord's formal complaints process or contact your local authority, depending on the situation. If the issue remains unresolved, consider getting advice from a housing specialist or solicitor.

Final Thoughts

Supporting a housing disrepair claim is about more than showing that damp or mould exists. Clear records can help establish the property's condition, the history of repair requests, the landlord's response, and any financial or health-related impact.

Start by taking dated photographs, reporting the problem in writing, and keeping copies of relevant documents. Add medical records, receipts, and professional reports where appropriate, and organise everything into a clear timeline.
