Damp Survey for Tenants — Your Rights and What to Do

Damp and mould in a rented home is not something you should have to live with — and increasingly, it’s not something your landlord can ignore. Here’s what you need to know about your rights, what evidence helps, and when an independent survey is useful.

Your landlord’s obligations

Landlords in England have duties relating to the condition and safety of rented homes, but the exact legal route depends on the type of tenancy and the circumstances. The Homes (Fitness for Human Habitation) Act 2018 can be relevant where a rented home is not fit for human habitation, including because of serious damp or mould.

If you rent social housing, Awaab’s Law is already in force. Since 27 October 2025, social landlords have had prescribed duties and timeframes for emergency hazards and damp and mould hazards that present a significant risk of harm. Phase 2 comes into force on 30 November 2026 and extends the significant-hazard requirements to further hazard types.

If you rent privately, Awaab’s Law does not yet apply to the private rented sector. The Renters’ Rights Act 2025 provides for it to be extended to privately rented homes, but the government’s implementation roadmap says the detailed requirements and commencement date are still subject to consultation. Other existing landlord duties may still apply, so tenants should use current official guidance or obtain advice about their particular situation.

How to document the problem

Before escalating a complaint, build a clear record:

• Report it in writing — email your landlord or letting agent so there’s a dated paper trail. Keep copies of all correspondence.
• Photograph everything — date-stamped photos of mould growth, damp patches, peeling wallpaper, and water ingress. Show the extent, not just the worst spots.
• Log when you reported it — the date of your first report matters if the case escalates. If Awaab’s Law applies, the landlord’s investigation window starts from this date.
• Keep a note of how the conditions affect use of the home — for example, rooms or belongings affected, recurring mould after cleaning, water ingress, or times when the problem becomes worse. If you have health concerns, seek appropriate medical advice rather than relying on a building survey to assess health effects.

When an independent survey helps

An independent survey can be useful where the cause of damp or mould is disputed or remains unclear. The aim is to document the building conditions and relevant evidence rather than start from an assumption that either the tenant or the landlord is responsible.

Depending on the property and symptoms, an investigation may consider moisture patterns, leaks or water ingress, ventilation, heating, insulation, cold surfaces and thermal bridging, construction defects and internal environmental conditions. Where appropriate, instrument readings can support that assessment, but they should be interpreted in context.

A written report may be useful when communicating with a landlord, managing agent, housing officer or professional adviser. If you are considering legal proceedings, ask your solicitor or adviser what form of evidence is required for your particular case.

What the survey covers

• Moisture readings where appropriate, interpreted alongside the wider evidence
• Environmental measurements such as temperature and relative humidity where relevant
• Ventilation provision considered where relevant to the reported problem and survey scope
• Assessment of the likely moisture source or contributing causes, based on the evidence available
• Written reporting where the relevant reporting tier is selected
