Who is responsible for mould in a rented property?
Mould is caused by numerous factors, including everything from how the building was constructed through to how furniture is arranged within the home. This can be an issue when deciding responsibility for mould growing in a home. Tenants may find themselves in properties that have poor insulation and ventilation. Whereas landlords may have tenants that may not take basic steps to prevent mould.
According to Shelter.org, landlords must fix problems that cause mould and damp, such as:
structural problems
faulty installation
leaking internal pipes
not enough ventilation
broken boilers and heating systems
cracked walls or rotten window frames
leaking roofs, missing roof tiles or faulty guttering
extractor fans they've installed.
Tenants should take reasonable steps to prevent mould and damp, such as:
open windows regularly
cover pans when cooking
dry clothes outdoors or in a dryer
close internal doors when cooking or showering
use extractor fans in the kitchen and bathroom
leave a gap between furniture and external walls
wipe condensation from window sills each morning.
How to prevent mould
For those with mouldy homes, we discovered the percentage of people doing simple things around the home that may have contributed to mould growth. Try to avoid the following to prevent mould from growing in your home.
Financial help for heating the home
Having a warm home is one of the best ways to prevent mould from growing. However, as the cost of living crisis has taken hold, 69% of people have admitted that they've put their heating on less due to cost in the past two years. Over 54% of these people believe that this is a direct cause of mould becoming more of a problem in their homes.
But for the 367,119 homes without central heating in the UK, adequately heating the home consistently enough to help prevent mould can be even trickier. Our Energy Statistics page delves deeper into the number of households without heating.
If you’re struggling with your energy bills, there is help available. Energy suppliers are required to have plans in place to help customers who need it. There are also various government-run support schemes, such as the Warm Home Discount, Winter Fuel Payment and Cold Weather Payment.
You can also compare energy deals to see if there might be a suitable fixed tariff on offer that you could switch to.
FAQs
How to prevent mould
By making a few simple changes within the home, you can help prevent mould from growing in your home.
Try to dry clothes outdoors or in a dryer where possible.
When cooking or showering, keep the room door closed. Make use of any ventilation fans every time, or open a window.
Maintain a healthy airflow throughout the home by opening windows frequently.
Take furniture directly off walls. Having a small gap between an item of furniture and the wall can mean a healthier airflow.
Cover saucepans with a lid when cooking, and ensure the extractor fan is on, especially when removing the lid.
Try to declutter. Untouched items piled on one another can become a breeding ground for mould.
Straighten out the shower curtain when wet. This also applies to anything else that may be damp in the house.
Mop up spillages instantly, and dry the area as best as possible to avoid it evaporation in the air.
Clean the carpets frequently.
How to clean mould
Ensure that you have the correct safety equipment, such as goggles, rubber gloves and a mask that covers your nose and mouth.
Ventilate the area by opening windows, and doors, and turning on any extractor fans.
With warm water and a regular detergent, you can gently wipe away mould on walls. Don’t brush it vigorously. Alternatively, you can use a dedicated mould remover cleaner and follow its instructions.
It's important to dry the area after the mould is removed. Use a clean and dry cloth to remove the remaining moisture.
For soft furnishing, they should be shampooed or professionally dry cleaned.
Can I paint over mould?

To help prevent mould growth in the future, you can use specific anti-mould paint.
How can I get a cheap gas and electricity deal?
It's going to be difficult, given the current state of the energy market, for many customers to find a cheap gas and electricity deal. Energy prices have risen by a significant amount, with deals a lot more expensive than they were a few years ago.
A standard variable tariff, which is capped at £1,690 until 30 June, may be the cheapest deal available for many customers. But some fixed deals could offer price certainty. Consider your options carefully and check out our energy Q&A here for more information.
Methodology and sources
Methodology
An FOI was sent to the Housing Ombudsman asking for a breakdown of complaints about mould/damp and leaks/flood in English local authorities by year for local authority and housing association-run properties. Data returned covered Financial Years 2018/19 to 2022/23 for mould damp and 2018/19 to 2021/22 for leaks/floods.
To compare this to the number of properties, 2022 data from the Regulator of Social Housing was taken on the number of LARP (local authority-run) and PRP (privately-run, including housing association) properties to provide an estimate of the number of complaints per property.
Data on % of properties with damp/mould was taken from the English Housing Survey.
2004 adults in the UK were also surveyed on their experiences and opinions on mould between 06/11/2023 and 08/11/2023.
