How to photograph mould evidence for your landlord or council
Good photos are the single most useful piece of damp and mould evidence you can gather. A calm, dated set of five clear images will do more for your case than a phone camera roll full of similar close-ups. This guide walks through exactly what to take, what to avoid, and how to keep your evidence organised over time.

In short
Take three photographs of every affected area: a wide shot that shows the whole wall and where it sits in the room, a medium shot with something for scale, and a close-up of the growth. Use daylight, keep the originals unedited, and repeat from the same spot weekly and after any visit or repair. Photographs prove presence, extent and change over time; they do not prove the cause, and they should never be presented as if they did.
- Tenants documenting damp or mould for a landlord, agent, council or adviser
- Homeowners preparing for a survey or an insurance claim
- Landlords recording an inspection
- Wide shot, medium shot, close-up, in that order
- Date every photograph and keep the originals
- Include a reference for scale and a fixed feature for position
- Repeat weekly from the same spot
- Store them with the written report and every reply
- UK-wide. The evidence habits are the same in every nation; what the photographs are used for differs by tenure and law.
- A photograph cannot show moisture content, what is behind the wall or whether the air is harmful
- Flash and heavy editing hide texture and colour; avoid both
- Illustrative images on this site are labelled as such and are not photographs of real cases

To photograph mould evidence properly, take five photos per affected area: a wide room shot, a mid-range shot showing the affected wall or ceiling in context, a close-up of the mould itself, a shot of any window, vent or leak source nearby, and a photo of the date on your phone or a newspaper. Keep faces, documents and children out of frame. Re-photograph the same spot every 1–2 weeks so you can show change over time.
Golden rule
One clear, dated wide shot is worth more than twenty phone-roll close-ups. Landlords, agents and councils need to see the room, not just the mould.
Why photos matter
In damp and mould disputes, the person with dated, organised evidence usually gets taken seriously first. Without photos, a report can be dismissed as exaggeration or lifestyle blame. With photos — especially ones showing the affected area in context — the conversation shifts from he-said-she-said to visible fact.
Photos also protect you if the issue gets worse before anyone visits. A dated set from six weeks ago is powerful evidence that the problem is not new, not caused by you last week, and not fixed by a single quick clean.
The five photos to take
For every affected area, aim for these five shots. They take less than five minutes and give a landlord, agent, council or specialist enough to work from without needing to ask you for more.
| # | Photo | Why it matters |
|---|---|---|
| 1 | Wide room shot | Shows scale, furniture placement, ventilation, windows — landlords want to see the whole context, not just the worst spot |
| 2 | Mid-range shot of the affected wall or ceiling | Shows where the mould sits within the room (corner, window reveal, behind furniture) |
| 3 | Close-up of the mould or damp patch | Shows colour, pattern and spread — helps distinguish surface mould from deeper damage |
| 4 | Nearby moisture source (window, vent, leak, radiator) | Explains likely cause — condensation, penetrating damp, leak |
| 5 | Date reference (phone screen with date visible, or newspaper) | Turns any photo into dated evidence a landlord or council can rely on |
Include a scale reference where useful
A ruler, a phone, a coin or your hand next to the affected area helps show real size — much clearer than 'a patch about this big' in an email.
What not to include in the frame
This matters because photos often end up shared with multiple parties: landlord, agent, letting agent's contractor, council environmental health, a specialist you may later instruct, and possibly the Housing Ombudsman. Assume every photo will travel further than you intended.
- Faces of tenants, family or visitors
- Children — even if the mould is in a child's room, keep them out of shot
- Documents, letters, bank statements, medication or anything with personal data
- Neighbours' property visible through windows
- Anything that could identify a specific address in a way you don't want shared later
How to date your evidence
Every phone photo already has hidden metadata (EXIF data) with a timestamp, but that can be lost when photos are compressed by email or messaging apps. Belt-and-braces is better.
- Take one photo with your phone screen visible in-frame showing today's date
- Or place today's newspaper in one shot
- Keep the original photos on your phone — do not delete them after sending
- When you email a set, mention the date the photos were taken in the body of the email, so the email itself becomes a dated record
- If you use a photo-based report, that report will carry its own dated case reference
How often to re-photograph
Damp and mould rarely stay the same. Re-photographing the same spot on a regular schedule turns a single snapshot into a timeline — and a timeline is much harder to dismiss.
- Weekly if the problem is spreading, if you have a vulnerable occupant, or if you have already reported it
- Every 2 weeks for a stable but ongoing issue
- Immediately after any repair, clean or treatment — from the same angle as before
- Immediately after a heavy rain event if you suspect penetrating damp or a leak
- Immediately if it visibly worsens, spreads, or returns after being cleaned
What landlords, agents and councils actually need to see
Most professionals looking at damp and mould photos are trying to answer three questions: where in the property is it, how serious is it, and what likely caused it. Your five photos should let them answer those questions without needing to visit — even if a visit is still the right next step.
Good evidence
- Wide shot showing room, window and ventilation
- Clear close-up with visible scale reference
- Dated evidence (phone screen, newspaper or email date)
- Photo of any nearby leak, vent or moisture source
- Multiple dates showing change over time
- Twenty near-identical close-ups from the same angle
- Photos with faces, documents or personal items in frame
- Screenshots of screenshots (loses metadata and quality)
- Cropped-in shots with no context of the room
- Photos with no date reference and no accompanying email
When photos are not enough
Photos are strong for surface evidence. They are weak — sometimes useless — for what is happening inside a wall, above a ceiling, under a floor, or in a roof void. If a landlord, agent or council pushes back on photos alone, that is often a legitimate signal that an in-person inspection is needed.
It is not a failure of your evidence. It is the boundary of what any photo-based report — including ours — can honestly tell you.
Signals to escalate to an in-person survey
Recurring after treatment, spreading fast, bulging or cracked plaster, timber decay, sagging ceiling, active leak, or vulnerable occupants (children under 2, elderly, respiratory conditions).
Frequently asked questions
Five is usually enough per affected area — a wide room shot, a mid-range shot, a close-up, a nearby moisture source (window, vent or leak), and a dated reference. More photos help if the problem spreads, but quality beats quantity.
No. Weekly is enough for a spreading or already-reported issue. Every 2 weeks for a stable ongoing issue. Immediately after any repair or clean, from the same angle as before.
Yes. Dated phone photos are routinely accepted as evidence by councils, letting agents, the Housing Ombudsman and courts. What matters is that the date is credible and the images have not been manipulated. This is general information, not legal advice.
Yes, where practical. Something familiar in the frame — a phone, coin, ruler or your hand — makes it much clearer how big the affected area actually is.
Photograph what you can see, note in your evidence that the wardrobe or sofa cannot easily be moved, and mention that the affected area may extend further. Do not injure yourself moving heavy furniture — the landlord or a contractor can inspect properly.
WhatsApp compresses photos and can strip metadata, which weakens them slightly as evidence. Where possible, email the originals as attachments (not embedded) so the full file is preserved.
No. Never put children or vulnerable occupants in frame. Note their presence in the accompanying email or report — 'A child under 2 sleeps in this room' — rather than in the image itself.
This is where dated series matter. A wide shot alongside the close-up, and a photo taken 4 weeks earlier from the same angle, is very hard to argue with. That is exactly what a Stop The Mould evidence pack organises for you.
