Freezing conditions have brought a troubling trend to light: over 60% of people in the UK have reported experiencing mould in their homes, up from 58% last year.
This pervasive issue affects all types of housing and highlights the financial strain many face in maintaining adequate heating.
In response, Uswitch has produced the latest Mouldy Nation Report exploring the prevalence of mould across local authorities, our attitudes towards it, and the habits that may contribute to its growth. The report also offers practical tips to help combat mould and save on energy costs.
Key findings from the study:
Prevalence of mould: Over 60% of respondents have experienced mould in their homes, with 31% encountering it more than once.
Accommodation types: Mould issues span across various housing types, including owned homes (43%), privately rented accommodations (28%), local authority housing (16%), housing association properties (12%), and student accommodation (7%).
Complaint dynamics: About 55% of respondents raised complaints about mould, primarily to landlords (22%) and local authorities or housing associations (around 15% each).
Responsibility for mould: A significant majority (69%) believe landlords are responsible for mould in rented properties, while 33% have been blamed for mould by landlords or management.
Impact of heating costs: Over 68% have reduced heating due to costs, with 56% believing this contributed to worsening mould problems. Additionally, 60% struggled with paying for adequate heating during mould occurrences.

Ben Galizzi, Uswitch energy expert, comments: “Living in a mouldy home is both unpleasant and a health hazard. Yet many of us have had to deal with mould at some point.
“Whether you rent or own, mould can be a constant problem if the root cause isn’t fixed. With poor insulation and rising energy costs, it’s harder than ever to keep it under control.
“Both landlords and tenants need to do their part in tackling mould. Tenants might need to adjust some habits at home, while landlords take care of bigger repairs to the property.
“Keeping your home warm, especially in the winter, can really help prevent mould. If you’re on a standard variable tariff and struggling with your energy costs, though, it might be worth checking out fixed energy deals to see if you could switch to a cheaper tariff than the one you’re on.”
