Damp and Mould Landlord Responsibility in Peterborough: Inspection and Repair Checklist
In most cases, a landlord must investigate reported damp and mould and repair any property defect causing or worsening it. This can include leaking pipes, roof or gutter defects, failed seals, damaged external walls, inadequate fixed ventilation or problems with the heating system. Tenants should use the heating and ventilation provided and report problems promptly, but advice about opening windows or changing daily habits is not a substitute for fixing the property.
The correct response is to identify the source, remove the health risk, complete the necessary repairs and check that the mould does not return.
In most cases, a landlord must investigate reported damp and mould and repair any property defect causing or worsening it. Tenant ventilation and heating practices can reduce condensation, but they do not replace necessary property repairs.
Peterborough landlords: If a tenant reports damp or mould, record the report, assess any health risk, arrange an inspection and deal with active leaks or other urgent hazards immediately. Do not simply paint over the affected area.

What is a landlord responsible for when damp or mould appears?
Under English housing law, landlords have duties relating to the condition, safety and fitness of rented homes. The precise responsibility depends on the cause, the tenancy and the facts of the case, but a landlord will normally need to act when damp or mould is connected to:
- a leaking roof, gutter, downpipe, window or external wall
- leaking water, waste or heating pipes
- defective bathroom or kitchen seals
- a damaged damp-proof course or another building defect
- faulty or inadequate fixed extractor fans or ventilation
- a heating system that does not work properly
- insulation defects or severe cold surfaces that make condensation difficult to control
- water damage that has not been properly dried and repaired
Government guidance says landlords should assess damp and mould urgently, remove the mould, identify the underlying cause and repair it. It specifically warns that removing surface mould alone will not stop it returning. See the government's guidance on damp and mould in rented homes .
Is damp and mould ever the tenant's responsibility?
A tenant may contribute to excess moisture by not using working extractor fans, blocking vents, drying large amounts of washing indoors without ventilation or failing to report a leak. However, that does not justify automatically describing the problem as “tenant lifestyle”.
The landlord should first establish whether the home has defects, inadequate ventilation, insufficient heating, poor insulation or another factor that makes condensation and mould more likely. Tenant guidance should be practical and specific to the property. It should accompany necessary repairs, not replace them.
A landlord considering charging a tenant for damage should obtain evidence of the cause, review the tenancy terms and deposit rules, and take legal advice where responsibility is disputed. Visible mould by itself does not prove tenant negligence. For a broader breakdown of who fixes what, see our landlord repair responsibilities guide.
Common causes of damp and mould in Peterborough rental properties
Peterborough City Council identifies four main causes: condensation, penetrating damp, rising damp and defective plumbing. More than one cause can exist at the same property.
| Possible cause | Common signs | Appropriate landlord response |
|---|---|---|
| Condensation | Black mould around windows, external-wall corners, ceilings or behind furniture; water on glazing | Check heating, extractor fans, trickle vents, insulation and cold surfaces. Give tenants practical moisture-control guidance and correct property defects. |
| Penetrating damp | Defined damp patches on an external wall or ceiling, often worse after rain | Inspect roof coverings, flashing, pointing, render, gutters, downpipes, windows and external seals; repair the source before internal redecoration. |
| Plumbing leak | Localised wet patch, staining, damaged ceiling or persistent damp near a bathroom, kitchen or pipe route | Stop the leak, check hidden damage, dry the structure and replace materials that cannot be safely dried or cleaned. If water is actively leaking through a ceiling, follow the immediate steps in our water-leaking guide. |
| Suspected rising damp | Low-level tide marks, salt deposits or damaged plaster at ground-floor level | Arrange a competent assessment. Do not assume every low-level damp patch requires chemical damp-proof injection. |
| Poor ventilation | Persistent high humidity, ineffective extractor fans, blocked vents or mould in wet rooms | Test existing ventilation and repair, clean or upgrade it where required. Controlled work must comply with applicable Building Regulations. |
| Cold bridging or insulation defects | Repeated mould in the same cold corners or wall junctions despite normal heating and ventilation | Investigate thermal defects and select a repair that does not create new ventilation or moisture problems. |
Why landlords should treat damp and mould as urgent
Damp and mould can affect the airways and lungs and may also affect the eyes, skin and mental health. Children, older people, pregnant women, people with respiratory conditions and people with weakened immune systems can face greater risk. A landlord should not wait for a tenant to provide medical evidence before investigating or acting.
If a tenant reports breathing difficulties or other symptoms, advise them to obtain medical help. Property repairs should continue without waiting for a diagnosis.
Treat the situation as particularly urgent where there is:
- extensive mould in a bedroom or main living area
- a baby, young child, older resident or medically vulnerable occupant
- an active leak near electrical fittings
- a bulging or waterlogged ceiling
- sewage-contaminated water
- a failed heating system during cold weather
- rapid deterioration or water entering during rainfall
Where there is immediate danger to life, occupants should call 999. A wet electrical installation should not be touched; use a qualified electrician and isolate the supply only if it is safe to do so. For ongoing or developing hazards needing a fast contractor response, see our emergency repairs in Peterborough page.
Damp and mould landlord responsibility under English law
Several legal standards can apply at the same time:
Landlord and Tenant Act 1985
Section 11 generally makes landlords responsible for keeping the structure and exterior in repair and maintaining installations for water, sanitation, heating and hot water. The fitness provisions added by the Homes (Fitness for Human Habitation) Act 2018 require relevant rented homes to remain fit for habitation. Serious damp and mould can make a home unfit.
Housing Act 2004 and HHSRS
Councils assess housing hazards through the Housing Health and Safety Rating System. Damp and mould can be assessed as a hazard. Councils must act when they identify a category 1 hazard and have powers to act on category 2 hazards.
Environmental Protection Act 1990
Severe damp or mould may amount to a statutory nuisance where the condition is prejudicial to health or a nuisance. The application of this law depends on the evidence and circumstances.
Renters' Rights Act 2025 enforcement
From 22 June 2026, councils gained power to issue civil penalties of up to £7,000 where private landlords fail to address serious hazards. This sits alongside other enforcement powers. The government explains the current measure in its June 2026 announcement on dangerous rented homes .
Does Awaab's Law apply to private landlords?
As at 19 August 2026, Awaab's Law's fixed damp-and-mould response times apply to social landlords. Its extension to the private rented sector is planned under the Renters' Rights Act, but the government's implementation roadmap says the timing remains subject to consultation.
Private landlords should therefore not advertise the social-housing deadlines as current private-rental law. They must still respond promptly under existing repair, fitness and hazard rules. Read the government's Renters' Rights Act implementation roadmap .

Peterborough damp and mould inspection and repair checklist
Ten steps from the first tenant report to the post-repair inspection.
Record the tenant’s report
Record the date, affected rooms, photographs, smells, visible water, recent weather and any health or vulnerability information the tenant voluntarily provides. Confirm in writing that the report has been received.
Triage the immediate risk
Ask whether water is still entering, whether electrics are affected, whether a ceiling is sagging and whether heating or ventilation has failed. Arrange an emergency response where the condition presents an immediate risk.
Inspect the property
An in-person inspection is normally more reliable than making a diagnosis from photographs. Check both inside and outside, including:
- roof and chimney junctions
- gutters and downpipes
- pointing, render and external cracks
- window and door seals
- plumbing, waste pipes and bathroom seals
- loft insulation and ventilation
- extractor fans and trickle vents
- radiators and fixed heating
- the pattern, height and location of damp or mould
Moisture-meter readings can assist an assessment, but a reading alone does not identify the cause.
Document the findings
Photograph the affected areas before cleaning. Record the likely cause, immediate action, proposed repair, contractor, access arrangements and target dates. Retain invoices and completion photographs.
Stop the moisture source
Repair leaks and external defects before treating internal finishes. If the cause is uncertain or involves possible structural, roofing, drainage or damp-proofing failure, use an appropriately competent specialist.
Dry the affected area properly
Plaster, timber, flooring and insulation may retain moisture after a leak is repaired. Allow sufficient drying time and monitor the area. Water-damaged materials that cannot be safely cleaned and dried may need removal.
Remove mould safely
Use suitable protective equipment, isolate the work area where appropriate, follow product instructions and avoid spreading spores into unaffected rooms. Large, recurring or concealed growth may require specialist remediation.
Repair damaged surfaces
Replace failed plasterboard, repair plaster and prepare surfaces only after the moisture source has been controlled and the area is sufficiently dry. Anti-mould coatings can support a complete repair but cannot compensate for an unresolved leak, cold bridge or ventilation problem.
Explain prevention measures
Show the tenant how to use extractor fans, trickle vents and heating controls. Ask them to report condensation, leaks or equipment failures early. Keep instructions realistic for the property and occupants.
Reinspect after the work
Government guidance recommends inspecting the home at least six weeks after remedial work to confirm the repair has worked and the mould has not returned. Recurrent mould requires further investigation, not another coat of paint.
What Peterborough landlords should not do
- ✗Do not paint over active mould or damp plaster.
- ✗Do not close a job after wiping the visible surface.
- ✗Do not diagnose the cause from one photograph.
- ✗Do not automatically blame the tenant.
- ✗Do not delay because the tenant has not supplied medical evidence.
- ✗Do not install ventilation, windows or heating equipment without checking applicable Building Regulations.
- ✗Do not describe a treatment as permanent unless the moisture source has been identified and corrected.
Local licensing and enforcement in Peterborough
Peterborough has selective licensing in designated private-rental areas. The council states that 3,141 inspections identified more than 17,000 health and safety hazards during the scheme's first 18 months, including damp and mould. Since 26 January 2026, Peterborough's additional licensing scheme has also covered HMOs occupied by three or four people forming multiple households, while national mandatory licensing applies to qualifying larger HMOs.
Landlords should check whether each property needs a selective, additional or mandatory HMO licence. Licensing does not replace the general duty to keep the home safe and in repair. See Peterborough City Council's selective licensing information .
If a council or Home Safe inspection identifies damp, ventilation or other repairs, our Selective Licensing Support service can help you plan agreed remedial work and organise completion records. Our Home Safe inspection repair-list guide explains how to request itemised quotes and retain evidence. The council decides whether licensing applies.

Frequently asked questions
Is a landlord responsible for black mould?
›
A landlord is normally responsible for investigating the cause and correcting property defects that cause or worsen mould. Tenant actions may contribute to humidity, but black mould alone does not establish who caused the problem. The property, heating, ventilation, insulation and occupant circumstances all need to be considered.
How quickly must a private landlord fix damp and mould?
›
There is no single fixed private-sector deadline covering every damp and mould case as at 19 August 2026. The response must be prompt and proportionate to the risk. Active leaks, electrical exposure, serious mould and risks to vulnerable occupants require urgent action. Awaab’s Law’s specific deadlines currently apply to social housing.
Is condensation always the tenant’s fault?
›
No. Condensation results from moisture meeting a cold surface. Occupant activities can increase moisture, but inadequate ventilation, ineffective heating, poor insulation, cold bridges and building defects can make the problem difficult to prevent. A proper inspection should assess all relevant factors.
Can a landlord just use mould-resistant paint?
›
No. Mould-resistant paint may form part of the finishing work after the cause has been corrected and the surface has dried. It will not repair a leak, failed extractor fan, cold bridge or other underlying defect.
Should a landlord inspect between tenancies?
›
Yes. Check behind furniture, inside cupboards, around windows, beneath sinks, around baths and showers, under roof spaces where accessible, and near external walls. Repair the cause and allow materials to dry before the next tenant moves in.
Can 360 diagnose damp from photographs?
›
Photographs can help identify urgency and plan an initial visit, but they may not show concealed leaks, external defects, retained moisture or ventilation performance. A site inspection or specialist assessment may be required.
