The scale of the problem
- Around 2 million homes in England are affected by significant damp and/or mould (around 3–4% of housing stock)
- Up to 1 in 3 UK adults report mould in their home frequently or occasionally in the past year, particularly in colder months
- An estimated 15 million people live in homes affected by damp, mould, or excessive cold
- Mould is not always visible - it can release microscopic spores into the air
- The UK is a cold, damp country - mould is an ongoing perplexing problem that affects many.
You are not alone!
Getting to the nitty gritty of mould...
Who does it affect?
- Around 5% of the population have a true mould allergy, but many more experience sensitivity, especially those with:
- asthma or respiratory conditions
- allergies
- eczema
- immune vulnerability
- chronic inflammatory or fatigue-type illnesses
- Sensitivity does not require visible mould or a formal allergy diagnosis.
Mould is often invisible
It can exist:
- behind furniture
- inside walls or ceilings
- under flooring
- behind cupboards
- around windows and insulation
- as airborne spores only
A home can feel “damp”, musty, or trigger symptoms before mould is visible.
