What Damp Records Should I Keep as a Landlord

UK context: what your damp file actually needs to prove (and why it matters)

You need damp and mould records that show you acted promptly, understood the risk, and chose reasonable fixes for the building you let and the law that applies where you operate. Good records don’t have to be complicated, but they do need to tell a clear story that would make sense to a council officer, Ombudsman, or judge who has never seen your property.

Across the UK, the pattern is similar even though the legal tests differ:

• In England and Wales, you are judged against repairing duties (for example, keeping structure, exterior and key installations in repair) and, in England, against fitness for human habitation throughout the tenancy.
• Councils use the Housing Health and Safety Rating System (HHSRS) to treat damp and mould as a health hazard, especially for children and people with respiratory issues.
• In Scotland and Northern Ireland, repairing standards and local enforcement routes change the detail, but the core question is the same: what did you know, what did you do, and how quickly did you do it?

If a case escalates, the arguments usually stop being about how bad the mould looked and start being about your timeline, your decisions, and whether you relied on vague ideas about “lifestyle” instead of evidence. A modest amount of discipline now prevents you trying to rebuild that history under pressure later.

Sussex Damp Experts work with landlords, agents and social housing teams who have learnt the hard way that memory, scattered emails and a couple of phone photos are not enough. A simple, repeatable file structure for each damp case gives you confidence that you can show both care for your tenants and control over your risk.

The core damp records checklist: what you want on file every time

You should aim to create the same small set of documents every time a damp or mould issue is raised so your handling is consistent, even when different people in your organisation touch the case. That way, any property professional or regulator who picks up the file can see what happened within a few minutes.

First, you want a one‑page case index. This notes the property, unit, affected rooms, the date and channel of the first report, a short description of the problem in the tenant’s own words, and who currently “owns” the next step. If you manage several homes, this alone can be the difference between calm and chaos when multiple complaints arrive at once.

Next, you want a simple chronological log. This is where you record each significant event: report received, acknowledgement sent, inspection booked, inspection done, contractors instructed, works completed, post‑works check, and any further contact. Each entry only needs a line or two, but together they show at a glance whether you were responsive or slow.

Around that skeleton you add:

• The tenancy agreement and any written variations that affect repairs, reporting routes or access.
• Copies of the tenant’s original report and key follow‑up messages in their own wording.
• Your inspection notes and photos.
• Your works instructions, quotes, invoices and any guarantees.
• Your follow‑up notes and any monitoring or reinspection.

Imagine you manage three self‑contained flats in one converted house. In January, two different tenants email about mould – one in a bedroom, one in a hallway cupboard. Because you always build the same index, log, photo set and works documents, each damp case sits in its own neat folder. When a surveyor or insurer later asks what you did and when, you can send a complete pack within minutes instead of scrolling back through months of mixed messages.

A good surveyor or damp specialist can help you take whatever you already have – emails, portal logs, photos, invoices – and re‑pack them into this basic structure once, so you can copy the model for future cases.

From “on notice” to “resolved”: records that show you acted reasonably

Your damp and mould records should show, in simple order, what you did from the first report until the problem was resolved. A clear trail needs to capture when you were told there was an issue, how seriously you treated it, how quickly you arranged inspection and works, and what checks you made afterwards so anyone reviewing the file can see that you acted reasonably rather than reactively.

You are not expected to predict problems you could not reasonably know about. Most disputes hinge on what happened after you were put on notice that there might be a damp or mould issue. Your records need to show how you moved from report to resolution.

The first step is a clear record of notice. Note when the tenant first told you there was a problem, how they contacted you, what exactly they described (for example, “black mould on bedroom ceiling above window” rather than “damp”), and whether anyone mentioned health issues or young children sleeping in the room.

Next comes triage. Within a day or two, you should have noted how you categorised the issue (for example, suspected leak, serious mould in a sleeping space, minor condensation) and what you decided about urgency. If you could not attend immediately, record any interim steps you offered, such as advising the tenant to move a bed away from a wet wall or providing temporary heating or drying where appropriate.

Access is another recurring flashpoint. Keep copies of appointment offers, reminder messages and any “no access” notes. If you have tried multiple times to gain entry and can evidence those attempts, it becomes much easier to show that delays were not of your making.

When you instruct works, note who you contacted, what you asked them to do and the target date for completion. When works are finished, add a simple closure entry: what was done, when, how you confirmed it was satisfactory, and whether any longer‑term monitoring or follow‑up is planned.

Picture two similar flats above shops on the same street, each with black mould around bedroom windows. In one file, the only record is a paid invoice for “mould wash” and a brief text confirming someone “popped round”. In the other, there is a short timeline showing the first report, triage, inspection, works and post‑works check. When a complaint reaches the council or Ombudsman, the landlord with the second file is in a far better position to show they acted reasonably.

Diagnosis and evidence: records that help you pin down the real cause

Mould on a wall is the symptom, not the cause. Your records need to prove (and why it matters is obvious when a dispute arises) that you made a serious attempt to work out why a surface is wet, not just that you wiped it off and painted over it. That is where good inspection and evidence records earn their keep.

Before you touch a moisture metre, make sure your inspection note forces you to consider the obvious structural suspects: blocked gutters, cracked render, slipped tiles, defective pointing, a bridged damp proof course, leaking pipework, failed sealants and poorly performing windows or doors. Write down what you checked and what you saw, including “no defect observed” where that is the case.

Photos should tell a story. Take a wide shot to show the whole room, a mid‑range shot to locate the patch in context, and close‑ups to show detail. If possible, capture something fixed in each frame (like a window, fireplace or door) so someone else can understand the location later. Keep the original files rather than only edited images.

If you use a moisture metre or hygrometer, record where it was used, on what surface or material, at what height and what the reading was. Note the limitations; a surface metre is useful for comparing damp patterns but does not, on its own, prove (and why it matters) that you have rising damp. Where you monitor relative humidity and temperature, keep a short note explaining where the device was placed, how often it logged data and over what period.

In some cases, especially where health impacts are claimed or causes are strongly disputed, commissioning an independent survey or specialist damp report is sensible. If you do, your file should include the full report and any key drawings or diagrams, not just the front page and invoice.

When a specialist damp firm carries out investigations, a large part of the value is the written reasoning: how the observations, measurements and building details fit together to explain the pattern of damp. You can mirror that approach in your own notes, even if you are recording a simpler case.

Works, variations and quality control: proving the fix matched the diagnosis

When you have a working theory of the cause, your records need to show that the remedial works you ordered actually addressed that cause and were carried out competently. Simply having “mould wash and repaint” invoices on file for repeated problems in the same corner of a room rarely satisfies anyone.

Start with a clear written scope for the contractor. Describe the problem you are trying to fix, any constraints (such as heritage fabric or access limitations), and what you expect them to do. If you are not specific, you risk getting cosmetic work where a structural repair or ventilation change was needed.

Keep basic due‑diligence records on the people you instruct – insurances, trade memberships where relevant and any references to damp work on similar buildings. You do not need a thick folder, but you should be able to show you did not simply pick the cheapest person with no experience.

Where works involve ventilation or heating, keep the product information, any commissioning results such as airflow readings or control settings, and the user instructions given at handover. If you are paying for a fan upgrade or a new positive‑input system to reduce condensation, you want something on file that shows it was sized and set up appropriately.

Variations are worth logging too. If a contractor opens up a wall and discovers a more serious leak, rotten timber, or an unexpected void, they may need to change the plan. A simple entry explaining what changed, why, who approved it and the cost or time impact keeps the picture honest when someone later asks why the job took longer or cost more.

At completion, a short quality‑control record ties it all together: what was done, what you inspected, any snags raised and resolved, and any guarantees or warranties provided. Good contractors routinely include before‑and‑after photos taken from the same viewpoint so you can see, and show others, what has actually changed.

Communication, complaints and “vulnerability‑safe” notes

Good communication and complaint records around damp and mould need to show that you listened, responded and kept residents informed at every key stage, and how you communicate about damp and mould often matters as much as what you do on site. A strong file makes it clear when concerns were raised, what you promised, how you updated people when plans changed, and how you handled any formal complaints so an external reviewer can follow the story without guessing. Complaint handlers and regulators look closely at whether you took concerns seriously, kept residents informed and avoided lazy assumptions about “lifestyle” where building defects could be in play.

A good communications log covers key contacts: who spoke to whom, when, by what route, what was discussed and what was agreed. It does not need to record every casual call, but it should capture the important moments: first complaint, promises about visits, notices of delays, and decisions about works.

When a complaint is raised formally, keep each stage response in order. That includes what the tenant alleged, how you looked into it, what you decided and what remedy or apology – if any – you offered. Many Ombudsman findings turn less on the original problem and more on how poorly the complaint trail is documented.

Temporary measures deserve a place in the record too. If you agreed a make‑safe visit, moved a bed, loaned drying equipment or prioritised one area over another while waiting for larger works, record what you did and why. This helps show you were managing risk rather than simply queuing jobs.

Think about a family reporting mould in a child’s bedroom in late autumn. You log the first call, agree an urgent visit, arrange a make‑safe clean and temporary dehumidifier within a couple of days, and explain when full works can be done. Each promise, update and change of plan is written down. Months later, if the case is reviewed, that trail shows you recognised the vulnerability, made interim provision and kept the household informed instead of leaving them guessing.

Notes that touch on health, disability or safeguarding need particular care. Record only what you were told and what action you took, not your own labels or speculations. Where you ask residents to take steps – such as allowing access, reporting leaks quickly, using installed extract fans or keeping trickle vents open – keep the wording neutral and link it back to the diagnostics and works you are undertaking, rather than presenting it as the whole solution.

This is an area where Sussex Damp Experts are often asked to review existing files. A few small changes to language and structure can make the difference between a record that looks defensive and one that clearly shows you were trying to protect your tenants and resolve the problem.

Storage, retention and disclosure: keeping enough – but not everything forever

As you build better records, the next question is how long to keep them and how to store them so they are useful without creating new risks. You want your damp files to be easy to find, easy to share when needed, and not kept longer than is sensible.

A simple retention schedule is a good start. Decide, in writing, how long you will keep damp and mould case files after a tenancy ends or a dispute is resolved. Many landlords choose periods that align with typical time limits for bringing claims, but the precise figure should reflect your own risk appetite and the kind of stock you manage. The important point is that you can explain your reasoning and apply it consistently.

Think about access as well as duration. Files that contain health information, photographs from inside homes and contact details should not be available to every staff member or contractor who happens to use your systems. Limiting access to those who need it to do their jobs reduces both privacy risk and mistakes.

From a practical standpoint, design your storage so you can produce a neat “disclosure pack” quickly if asked. That usually means a property‑by‑property structure, a clear naming convention that includes the date and document type, and a way of exporting a copy set without disturbing your originals.

Version control is another quiet but important safeguard. If you regularly update standard letters, inspection templates or guidance leaflets, keep a note of when each version came into use. That way, if someone questions what you told a tenant two years ago, you can show which information they actually received.

A specialist damp firm can help you sense‑check your current approach, but even a simple move from loose email chains and phone photos to dated folders with standard names can dramatically improve how robust your files look when they are scrutinised.
