Damp and Mould in UK Rented Homes: What Landlords Must Do and What Tenants Can Ask For

Damp and mould are among the most common complaints in UK rented homes, and a poorly handled case can lead to enforcement action, compensation claims and a lost tenant. For an overseas landlord who is not on site, the risk is higher because problems can grow unseen.

This Banke UK guide explains where a landlord's duties come from in England, how to deal with a report, and what to check on a property before you buy it to let.

The Short Answer

In England, a landlord must keep the structure and exterior of a rented home in repair and must let a home that is fit for people to live in. A home with serious damp and mould can be a hazard under the Housing Health and Safety Rating System, which councils use to inspect and enforce. Landlords should treat every report as a repair issue, find the cause and fix it, instead of blaming the tenant's lifestyle. Rules are changing, so check the current position for your tenancy.

Where the Duties Come From

  • Landlord and Tenant Act 1985, section 11. For most short tenancies the landlord must keep in repair the structure and exterior, and the installations for water, gas, electricity, heating and sanitation.
  • Homes (Fitness for Human Habitation) Act 2018. The home must be fit to live in at the start and throughout the tenancy. Serious damp and mould can make a home unfit.
  • Housing Health and Safety Rating System (HHSRS). Local authorities use it to assess hazards, including damp and mould growth, and can require works.
  • Awaab's Law. This follows the death of a toddler from mould exposure in social housing. It began in social housing in England in stages. The government has said it intends to bring similar duties to private renting, so confirm the current rules and dates.

Why Damp Happens

A fix starts with the cause. There are usually three kinds:

  • Penetrating damp. Water gets in through a defective roof, gutter, wall, window or pointing.
  • Rising damp. Moisture rises from the ground because a damp-proof course is missing or has failed. It is less common than people think.
  • Condensation. Warm moist air meets cold surfaces. It is linked to heating, ventilation, insulation and how the home is used.

Avoid assuming condensation without a survey. A report from a qualified surveyor or a damp specialist is stronger evidence than a guess, and it protects both sides.

How a Landlord Should Respond

  • Acknowledge the report in writing promptly.
  • Arrange an inspection and find the cause. Photograph the affected areas.
  • Fix defects first, such as leaks, gutters and failed ventilation, then deal with the mould.
  • Keep records of dates, contractors and what was done.
  • Follow up with the tenant after the work and check the problem has not returned.
  • Use a managing agent if you live abroad, and make sure they report faults to you quickly. Our guide to flood risk, damp and subsidence checks before buying helps with the purchase stage.

What Tenants Can Ask For

  • A prompt inspection and a repair plan in writing.
  • Work done within a reasonable time, taking account of the risk to health.
  • Advice from the landlord on ventilation and heating that is fair and practical.
  • To contact the local council's environmental health team if the landlord does not act.
  • Possible compensation or a rent reduction in serious cases, usually after legal advice.

Checks Before You Buy to Let

  • Commission a RICS survey at an appropriate level and read the damp findings.
  • Look at the roof, gutters, windows and external walls for signs of water ingress.
  • Check ventilation in kitchens and bathrooms, including extractor fans.
  • Check insulation and heating. Poor energy performance links to condensation. See new EPC rules for landlords.
  • Ask the seller about past damp, repairs and any council notices.
  • In a flat, ask the managing agent about leaks from neighbours or the building.
