3 Tips to Reduce Humidity and Prevent Mould in Your Home
As we gear up for another hopeful yet unpredictable UK summer, it’s time to prepare for a surprising seasonal issue many homeowners overlook. While mould is often associated with colder months, the combination of increased humidity and warmer temperatures can turn summer into a hotspot for mould growth, particularly in less ventilated spaces like bathrooms, kitchens and utility rooms.
A recently commissioned YouGov survey by leading British heating experts Wunda Group found that, in a bid to tackle damp and mould, over a quarter (29%) of homeowners turn on their conventional heating. The research also revealed that just over a quarter (26%) of UK homeowners use their heating to dry clothes indoors, a figure that rises significantly to 39% among 25–34-year-olds. While this may seem like a practical solution, it can actually contribute to excess moisture and worsen damp conditions within the home.
This behaviour reflects a wider issue. Approximately 904,000 homes in England were reported to have a damp problem in 2021 alone, and the number continues to rise. Although radiators produce warm air that can hold moisture, they do not distribute heat evenly across a room. This imbalance allows colder surfaces to remain, where condensation can form and mould can develop. While conventional heating is often used as a quick fix, more advanced solutions such as underfloor heating combined with smart controls offer a more effective, long-term approach.
Tom Edmunds, General Manager at Wunda Group, shares three key actions homeowners can take to help prevent mould and damp problems during the summer months.
How to Improve Ventilation Throughout Your Home for Healthier Air
Ventilation remains one of the simplest and most effective ways to reduce the risk of mould. Allowing fresh air to circulate helps prevent moisture from building up, which is a key contributor to mould growth. This is particularly important in areas that naturally generate more humidity, such as bathrooms, kitchens and utility spaces. During the summer, homes can quickly become stagnant, especially if windows and doors remain closed while occupants are away. On returning home, opening windows and internal doors can help reintroduce airflow and rebalance humidity levels.
Monitor and Manage Indoor Humidity Levels to Stop Damp and Mould
Keeping track of humidity levels is essential in preventing both mould growth and potential health issues. Many homeowners are unaware of rising moisture levels until visible signs of damp appear. Smart heating systems, which include room-by-room thermostatic control, provide a more precise way to monitor conditions throughout the home. By using smart thermostats to measure humidity in individual spaces, homeowners can take early action before moisture develops into a more serious problem. This proactive approach helps maintain a healthier indoor environment throughout the year.
Consider Underfloor Heating (UFH) for Long-Term Mould and Damp Protection
While installing underfloor heating may seem like a significant investment, it offers a highly effective solution for managing moisture and preventing damp over time. Unlike traditional radiators, which heat specific areas, underfloor heating distributes warmth evenly across the entire floor surface. This consistent heat reduces cold spots where condensation typically forms, helping to minimise the risk of mould growth.
Because warm air can retain more moisture than cold air, maintaining a stable, evenly heated environment makes rooms less susceptible to damp conditions. This is especially beneficial in moisture-prone areas such as bathrooms and utility rooms. Modern underfloor heating systems also offer retrofit solutions that are easier to install than many homeowners might expect, making them an increasingly accessible option for improving comfort and protecting against damp.
By taking a more informed and proactive approach to humidity and heating, homeowners can stay ahead of mould issues this summer, creating healthier and more comfortable living spaces all year round.
