Can I Complain About My Letting Agent for Damp

Damp & mould in your rental: who to complain to (and what you’re actually asking for)

You can complain to your letting agent about damp and mould, but you are really doing two things at once: asking for repairs and challenging how the problem has been handled, including basic Letting agent responsibilities. When you separate those two strands clearly, it becomes much harder for anyone to ignore you or pass you back and forth. It also helps you decide what evidence to gather, which rules apply and which organisations may be able to back you up if things do not improve.

Agent, landlord and who actually fixes things

In a typical private tenancy in England, the landlord is the one with the core legal duty to keep the structure, exterior and key services of the property in repair and to make sure it is fit to live in. Damp and mould often sit within those obligations where they arise from leaks, defective gutters, failed extract fans, broken heating or problems with the fabric of the building. The letting agent usually acts on the landlord’s behalf: they do not “take over” the landlord’s legal duty, whether the owner is a private landlord or another type of landlord, but they are paid to manage repairs day to day, pass on your reports, arrange inspections and contractors, and keep you updated. When you complain, you are mainly saying “the landlord must get this fixed” and “the agent has not managed this properly”.

Why you should write to both, not just the agent

If you want your complaint about damp and mould to be taken seriously, you are safer when both the landlord and the agent receive the same clear, written account of what is happening. A short letter or email that goes to both, with the property address and your key concerns, creates a single version of events that is hard to deny later. It also shows that you are giving everyone a fair opportunity to respond before you consider escalation.

If you only speak to the agent by phone, or only copy them into messages, it is very easy for responsibility to blur. You are safer if you:

• Put things in writing.
• Address your message to both the landlord and the letting agent.
• Ask for a written acknowledgement.

That way, nobody can say they were unaware, and the agent cannot quietly fail to tell the landlord what is happening. If the agent is not fully managing the property and only found the tenant for the landlord, your messages still give the landlord a clear chance to act.

Complaints about service as well as repairs

You strengthen your position if you separate the question “what repairs are needed?” from “how have my reports been handled?”, especially when dealing with a private landlord. A repairs request is about fixing the building; a service complaint is about how the agent or landlord has behaved. Making that distinction lets you say you want both the damp dealt with properly and the handling of your case reviewed, without sounding unreasonable or confused about the difference.

A repairs request is “there is damp, please fix the cause”. A service complaint is “the way you have handled my reports is not acceptable”. You are entitled to do both. Common service issues include:

• Ignoring messages or taking weeks to reply.
• Saying they will send someone out, but not doing so.
• Saying “it’s just condensation” without inspection.
• Losing records or giving contradictory information.

When you complain, say plainly that you are making a formal complaint about how your damp reports have been handled, as well as asking for repairs.

Ask for the agent’s complaints procedure and redress scheme

If your complaint may end up with an ombudsman-style body, it helps to show from the start that you are using recognised channels. Asking for the agent’s written complaints procedure and the name of their redress scheme signals that you understand there is a process and intend to follow it. It also sets a clear path from “raising concerns” to “formal decision”, which can be very useful if you later need to prove that you acted reasonably.

Agents in England and Wales must belong to an approved redress scheme. Those schemes will only usually look at your case after you have followed the agent’s own complaints process and received a “final response” or reached a time limit. Early in your correspondence you can safely ask:

• For a copy of the agent’s written complaints procedure.
• Which redress scheme they belong to and their membership number.
• What counts as their final response.

You are not threatening anyone by doing this. You are simply making it clear that you intend to use the proper channels if they do not resolve things.

Why escalating damp handling early matters: health, habitability and risk

You should not wait until damp and mould become severe before you complain firmly, because both health risks and repair costs usually get worse over time. Early, calm escalation shows that you are taking the issue seriously and gives everyone a better chance to sort it out before it turns into a dispute. It also gives you time to collect evidence, explore support routes and avoid last‑minute, high‑stress decisions about whether you can stay in the property.

How damp and mould can affect health and day-to-day life

Damp and mould affect more than just how your walls look; they can change how you use your home and how comfortable you feel living there. A clear description of which rooms you avoid, how often you are cleaning mould and whether belongings are being damaged helps others see the problem as more than minor staining. You do not need to be a doctor to describe the practical impact of damp and mould in your home; you can simply explain what you observe and then let others draw their own conclusions.

You can explain, for example:

• Which rooms you can no longer comfortably use.
• How often you are wiping mould from surfaces.
• Whether clothing, bedding or furniture is becoming musty or stained.
• Whether anyone in the home is coughing more, wheezing or using inhalers more often.

Health bodies consistently highlight that damp and mould can aggravate asthma and other breathing problems, especially for young children, older people and anyone with existing respiratory conditions. You do not have to prove that damp has caused an illness, but you can and should say if there are people in the home who could be more at risk.

Why delay usually makes the problem bigger

Time almost never improves a damp problem, and delay usually means both more disruption for you and higher costs for whoever pays for the work. Moisture that is left to linger often moves deeper into the structure, undermines finishes and turns a simple repair into a more invasive job. Making this clear in your complaint helps the agent and landlord see that acting early protects the building as well as your comfort.

Moisture does not politely stay on the surface. Left over months or winters it can:

• Move deeper into plaster, timber and floorboards.
• Damage finishes beyond simple cleaning and repainting.
• Increase the time and cost needed for drying and repair.

From a landlord’s and agent’s point of view, early diagnosis and targeted work nearly always cost less than repeated “wipe and paint” visits. From your point of view, early escalation lowers the chance that you end up living in one usable room while arguments continue around you.

You are more likely to be taken seriously if you describe damp and mould as a housing‑standards issue rather than a falling‑out with your agent. Councils, redress schemes and advice bodies assess risks and responsibilities, so they need clear information about how the building is performing, not only how annoyed you feel. Framing things this way also helps you stay calm and factual when emotions are running high.

It helps to talk about damp and mould as a housing-conditions risk, not a personality clash with the agent. Councils and ombudsman-style bodies look at whether a home is being managed in line with expected standards. If you describe:

• The condition of walls, ceilings, floors and windows.
• How many rooms are affected.
• How long it has been going on.
• Any vulnerability in your household.

you are giving them the information they need to treat your case as serious. That is more effective than focusing only on how frustrated you feel, even though your feelings are understandable.

Responsibility map: what the landlord must fix and what the agent must do

Understanding who is responsible for what turns a vague complaint into a focused request that is harder to brush aside. In law, landlords usually carry the duty to keep the structure, exterior and key services in repair and to make the property fit to live in. Agents are normally paid to manage those duties day to day, and you have your own “tenant‑like” responsibilities as well. When you know these buckets, you can frame your letters and follow‑up questions much more precisely.

Landlord duties around damp and mould

Landlords are expected to do more than hand over the keys; they must keep the structure, exterior and core services of the building in proper repair. That covers roofs, gutters, external walls, windows, doors and the installations that provide water, heating and hot water. Damp and mould that come from leaking fabric, defective services or building design usually sit inside these duties, so it is reasonable to link what you see to likely repair categories in your complaint.

Most private landlords must:

• Keep the structure and exterior in repair. That includes roofs, external walls, gutters, downpipes, windows and doors.
• Keep installations for water, space heating and hot water in repair.
• Make sure the property is fit to live in throughout the tenancy.

Damp and mould often fall under these duties where they result from:

• Leaks from roofs, pipes, bathrooms or kitchens.
• Failed or undersized extract fans in kitchens and bathrooms.
• Rotten or defective windows that allow water in or cold bridging.
• Defective pointing, render or damp proof courses.
• Poor insulation or other defects that leave surfaces cold and prone to condensation.

When you complain, it helps to connect the symptoms you see to likely repair categories. For example, “there is mould on the bedroom ceiling and a damp patch after rain, directly below the flat roof” points towards a building issue rather than only “lifestyle condensation”.

Letting agent responsibilities in practice

While the landlord holds the legal duty, letting agents are usually the people you deal with when you report damp and mould, and Letting agent responsibilities include managing that process competently. A good agent logs your report, passes it to the landlord, instructs suitable contractors where authorised, and keeps you informed about what is happening. When that does not occur, you can legitimately complain about the service you have received as well as the underlying repair.

The agent’s role is usually set out in their agreement with the landlord, not in your tenancy. In reality, where they manage the property they are expected to:

• Log your repair reports accurately and promptly.
• Pass them to the landlord and, if authorised, instruct contractors.
• Keep you informed about what is happening.
• Keep records of visits, findings and works.

You can complain about the agent if they:

• Fail to log or pass on reports.
• Repeatedly promise action that does not happen.
• Dismiss damp as “just condensation” without inspection.
• Lose track of which contractor saw what and when.

The fact that the landlord holds the legal duty for repairs does not stop you holding the agent to account for poor handling of your case.

Your own “tenant-like” responsibilities

You put your case on firmer ground when you show that you understand and are meeting your own basic responsibilities. Tenants are generally expected to behave in a “tenant‑like” way: using the heating and ventilation provided, reporting issues promptly and not doing things that obviously make damp worse. A short, factual description of what you already do makes it easier for others to see that the building, not just your habits, needs attention.

You are expected to look after the property in a normal, reasonable way. That usually means:

• Using heating and ventilation as provided and as you can sensibly afford.
• Not blocking air bricks or vents.
• Not deliberately drying washing in rooms with no ventilation if other options exist.
• Reporting leaks, heavy condensation and early signs of mould promptly.

Acknowledging these points in your complaint can actually help you. You can say, for example, “we open the bedroom window most mornings and run the bathroom fan after showers, but mould is still spreading on the ceiling and external wall”. That shows you are not refusing to take steps while still pointing to a likely building defect.

Where damp complaints go wrong: common agent replies and how to challenge them

When you report damp and mould, you are quite likely to hear familiar stock phrases rather than a thoughtful response. Being ready for those replies helps you stay calm, ask for evidence and push the conversation towards inspection and repairs instead of arguments about your lifestyle. Many renters hear the same stock responses, and you put yourself in a stronger position if you know how to ask better questions rather than getting drawn into circular debates.

“It’s just condensation, open the windows more”

When an agent blames everything on “just condensation”, they are often trying to close down the issue without proper investigation. You do not have to accept that as the end of the discussion. Instead, you can ask calm, practical questions about what has actually been inspected, what measurements have been taken and whether the ventilation is suitable for how the home is used, while also explaining what you already do to manage moisture. Condensation is real, but it is not a magic explanation that ends the conversation.

You can respond calmly by asking:

• What, exactly, has been inspected inside and outside the property?
• Have any measurements of humidity or surface temperatures been taken?
• Is the ventilation in the property considered suitable for the number of occupants and the way the rooms are used?

You can also explain what you already do to ventilate and heat the home. If you have been logging humidity and temperature, you can give those figures. That pushes the discussion towards evidence instead of assumptions about your lifestyle.

“We’ll repaint it; that will sort it”

An offer to clean and repaint can sound reassuring, but on its own it rarely deals with the cause of damp and mould. You are entitled to ask what has been found, what is being repaired and how anyone knows the underlying moisture has been dealt with. Framing your questions around cause and diagnosis, rather than refusing cosmetic work outright, helps you come across as reasonable while keeping the focus on the building.

Cleaning and repainting can be appropriate as part of a proper plan, particularly after repairs and drying. On its own, it rarely solves anything. Before you agree, you can reasonably ask:

• What does the agent or contractor believe is causing the moisture?
• Has any leak, defective gutter, missing pointing or similar issue been found and fixed?
• Have they checked for cold spots or bridging that might need insulation or other building work?

If you live in a solid-wall or older building, it is particularly important that the materials used are compatible with how the structure is meant to breathe. Hard, impermeable finishes can trap moisture in the wall and push damp elsewhere.

“We sent someone out; they found no issue”

Being told that a contractor “found no issue” when you still see mould or damp patches can be very discouraging, but you can respond in a way that builds your evidence rather than ends the conversation. Asking for a short written summary of what the contractor looked at, what they did and what they concluded gives you something concrete to compare with your own photos and notes. If symptoms continue, that contrast can be powerful when you escalate.

If a contractor has visited and you are told “no issue found”, you can request a short written note of what was actually done, such as:

• Where they looked.
• What they did or did not open up.
• Whether they tested any services.
• Whether they used any diagnostic tools.

You can then add your own dated photos and notes to show that symptoms are still present. That combination often carries more weight than your word against theirs.

Evidence that strengthens a damp complaint: what to collect before you escalate

A strong complaint about damp is not just a long story; it is a small, neat bundle of proof that a manager, redress scheme or council officer can check quickly. The more organised you are, the easier it is for others to see that you have been reasonable and the problem is real. Good evidence also helps any independent damp specialist, such as Sussex Damp Experts, to understand what has been happening over time rather than guessing from a single visit.

Build a simple damp timeline

A basic timeline turns scattered memories into a clear, dated record of how the problem has developed. You do not need any special software: a notebook, spreadsheet or simple document is enough if you use it consistently. By logging when you first noticed damp, when it spread, when you reported it and what responses you received, you make it much easier for someone else to see patterns and spot long gaps in action. Include:

• The date you first noticed the problem.
• Brief entries when things get worse or spread.
• The dates you reported issues and to whom.
• The dates and outcomes of any inspections or visits.

Alongside this, take clear, dated photos or short videos:

• One wider shot to show which wall, ceiling or room is affected.
• One close-up shot to show the detail of mould, bubbling paint, staining or damaged materials.
• Occasional repeat photos from the same angle to show progression.

Taken together, this gives anyone reviewing your case a quick visual and written overview of how long the issue has been present and how it has changed.

Add basic measurements if you can

Simple measurements can add weight to your complaint without turning you into a surveyor. If you have an inexpensive hygrometer or a thermostat, you can record temperature and humidity at roughly the same time each day, along with notes about whether windows were open or heating was on. These logs do not have to be perfect; they are there to show that you have tried to monitor the situation and that there is data available if someone wants to look more closely.

If you have access to an inexpensive hygrometer or thermostat, you can log:

• Room temperature and relative humidity at roughly the same time each day.
• Any notes on whether windows were open, heating was on or showers were taken.

You do not need to interpret those numbers yourself. The point is to show that you are monitoring conditions and that patterns can be checked later by someone with technical knowledge.

Keep proof of notice and access

Many disputes boil down to whether the landlord and agent were given a fair chance to inspect and repair, so it pays to keep a clear record of contact and access. Saving copies of emails, letters and text messages, along with notes of offered appointment times and who actually attended, helps you show that you have cooperated throughout. If a contractor reports “no access”, your records can quickly confirm whether that is accurate.

You protect yourself if you:

• Keep copies of messages you have sent and received.
• Note when you offered times for access and whether anyone attended.
• Save any contractor notes or “no fault found” comments.

When you are ready to escalate, you can assemble your evidence into a short index, the timeline, key emails or letters, and a photo sheet. That is much easier for someone to review than a pile of unlabelled screenshots.

Writing the complaint so it is taken seriously: structure, timescales and remedies

A complaint about damp and mould is more likely to be taken seriously when it reads like a concise report that someone outside the situation can follow. That means setting out who you are, what has happened, how it affects daily living and what you are asking for, rather than venting frustration. A well‑structured complaint reads like a clear report, not a rant, which makes it more likely to be logged properly, responded to by someone senior and respected if it is later reviewed externally.

Give your complaint a clear subject and shape

The way you frame your complaint on the page strongly influences how it is handled. A precise subject line and simple headings tell the reader that this is a formal, organised report, not a casual note. When you set out background, problems, actions so far, evidence and what you want in separate blocks, you make it much harder for anyone to claim they did not understand what you were asking for.

A subject line such as “Formal complaint: handling of damp and mould reports at [address] + repair request” tells the reader immediately that this is not a casual enquiry. In the body, you can organise your message under simple headings:

• Background: who you are, the tenancy start date and who you have been dealing with.
• Problem: where the damp and mould are, how long it has been going on, and how it affects day-to-day use of the home.
• Actions so far: who you told, when, and what responses or visits there have been.
• Evidence: the photos, logs and notes you have attached.
• What you are asking for: inspection, diagnosis, repairs, timescales and updates.

Numbering your requests makes it very obvious whether they have been answered.

Ask for diagnosis, not just decoration

A key line in your complaint can be along the lines of: “I am asking for a proper inspection and diagnosis of the cause of the damp and mould, and for repairs that address that cause, not just cleaning and repainting.” That keeps attention on the building and services, not only on surfaces.

You can also say that you are happy for the landlord or agent to appoint their own contractor, but that you would like findings in writing and an opportunity to see what has been concluded.

Set fair timescales and ask for an action plan

When you ask for action, it helps to show that you understand repairs take time but that you also expect progress. Suggesting reasonable timeframes for acknowledgement, inspection and a written plan tells the agent or landlord what “moving things forward” looks like in practice. Explaining how bad the impact is and whether anyone in the home is vulnerable gives useful context for why you think quicker or slower timescales are fair.

What is “reasonable” depends on how severe the problem is and whether anyone in your home is particularly vulnerable. As a starting point, many people ask for:

• An acknowledgement within a few working days.
• An inspection within one to two weeks, or quicker if the situation is clearly serious.
• A written plan with target dates once the cause is known.

If a room is effectively unusable, or there are clear health risks, you can say so and ask whether any temporary measures will be offered while full works are arranged.

Throughout, keep your language as calm and factual as you can. That does not mean you have to play down the impact, but it does mean focusing on what someone outside the situation would recognise as clear, checkable information.

If the agent still does not act: escalation routes that match your situation

If you have complained clearly, given a fair chance to respond and still see no meaningful progress, you can move beyond chasing emails. At that point, the question is whether your main problem is poor service, unsafe conditions or both, because different bodies deal with different issues. Knowing the main escalation routes – the agent’s redress scheme, the local council and independent legal or housing advice – helps you choose the next step that fits your situation so you do not stay stuck.

Using the agent’s redress scheme for service failures

The agent’s redress scheme is usually the right place to challenge poor service rather than the state of the building itself. If your main issues are being ignored, misled or bounced around, you can ask the scheme to look at whether the agent has followed expected standards once you have exhausted their internal process. Where the core problem is how the agent has behaved—ignoring you, misinforming you, losing records, failing to follow their own procedures—you can usually go to the redress scheme they belong to after:

• Using their internal complaints procedure.
• Either receiving a final response or reaching the time limit set in that procedure.

The scheme will normally look at whether the agent’s service met expected standards and may recommend apologies, changes in process or financial awards where poor handling and impact are evident. They do not usually order building works in the way a court or council can.

Involving the council for serious housing conditions

If the main concern is that the property itself is unsafe or clearly below acceptable standards, your local council’s private housing or environmental health team is often the stronger route. Councils can inspect, assess damp and mould as hazards and, in some cases, require landlords to carry out improvements. Going to the council is a serious step, so it usually makes sense once you have tried landlord and agent channels and can show that the problem is still affecting how you live in the home.

If the property itself is unsafe or clearly below acceptable standards and the landlord is not acting, your local council’s private housing or environmental health team may be the more powerful route. They can:

• Inspect the property.
• Assess hazards such as damp and mould.
• Order improvements in some circumstances.

When you contact them, your existing evidence pack is extremely useful. You can explain that you have already been through the landlord and agent channels and set out the risk to health and the way the home is being affected.

Getting advice before taking legal or high-risk steps

Steps such as withholding rent, moving out early or starting court action can have serious consequences if they are not handled carefully. Before you do anything that might be treated as a breach of your agreement, it is sensible to take independent advice on your options, protections and risks. Sharing your full timeline and correspondence with an adviser helps them give you a realistic view of what each route involves and how strong your case looks.

Some steps carry extra risk for you if they are not handled carefully, particularly withholding rent or ending the tenancy early. Before you do anything that might be treated as a breach of your agreement, it is wise to:

• Seek independent housing advice.
• Ask about protections against retaliatory eviction in your situation.
• Share your evidence so an adviser can see the whole picture.

If you are considering court action, a solicitor or advice agency can explain what kind of proof and process are involved, so you can decide whether it is proportionate.

Book Your Consultation With Sussex Damp Experts Today

When you book a consultation with a specialist damp company, you get clear guidance on whether you need a full damp survey, a lighter inspection or simply a better‑organised evidence pack to support your complaint. Instead of guessing what is “serious enough” or arguing in circles with your agent, you can speak to someone whose only job is to understand the building and help you choose the lightest, most effective next step that still protects your health, comfort and position.

You do not have to decide on your own whether your situation needs a full damp survey, a shorter inspection or simply a better-organised evidence pack. A focused consultation can help you choose the lightest option that still moves things forward.

How an independent assessment can support your complaint

An independent assessment gives you something more solid than opinion: it provides a clear description of what is happening in the building and what the likely causes are. A good survey or inspection will look at the structure, services, ventilation and how the home is used, then explain how those pieces fit together. When you ask a specialist to look at your home, the aim is not to win an argument; it is to understand what the building is doing so you can use that summary to support your complaint, to brief the council or to weigh up options if you are considering staying, negotiating or moving on.

A good assessment will:

• Identify the most likely sources of moisture (for example, leaks, penetration, bridging or condensation driven by building design).
• Explain how building features, ventilation and use interact.
• Set out practical options to tackle the cause, not just the symptoms.

You can then attach the summary to your complaint to show that your concerns are grounded in observed facts, not just personal opinion.

Making the most of a consultation with Sussex Damp Experts

You get more value from any consultation when you arrive with your information in order and a clear idea of what you want to understand. Bringing a brief timeline, a handful of key photos and copies of important emails means the discussion can focus on causes and options rather than trying to piece the story together from memory. In return, you should expect a plain‑English explanation you can share with your letting agent, landlord, adviser or council officer.

If you decide to involve a specialist damp company, you put yourself in a stronger position by coming prepared. You can bring:

• Your timeline of events.
• Key photos or short videos.
• Any humidity or temperature notes you have kept.
• Copies of important emails or letters with the agent or landlord.

That allows the inspection and discussion to focus quickly on what matters. You can then expect a plain-English explanation of what is happening and a set of suggested next steps, written in a way you can share with your letting agent, landlord, adviser or council officer.

Why a local, building-aware view matters in Sussex

Local, building‑aware insight matters because damp behaves very differently in a coastal Victorian terrace than in a modern flat with mechanical ventilation. Properties in Sussex see a mix of coastal exposure, wind-driven rain and older building types alongside newer construction, so “standard” treatments can easily be the wrong ones. A specialist who understands that context can help you avoid quick fixes that simply move the problem, clash with heritage requirements or create new damp risks elsewhere in the structure.

If you are at the point where messages to your letting agent are going nowhere, rooms are becoming hard to live in and you are not sure what to do next, it is reasonable to ask for help. Book a consultation with Sussex Damp Experts so you can turn a frustrating situation into a clear plan, backed by evidence, and give your complaint the weight it needs.
