Condensation occurs when warm moisture-laden air contacts cold surfaces, releasing water droplets. In UK homes, this typically manifests on windows and external walls during colder months, potentially leading to mould growth and structural damage if left unaddressed.
Understanding Condensation in UK Homes
The Science Behind the Drips
Condensation forms through three key mechanisms:
- Temperature Differential: UK homes average 18-21°C internally vs. external winter temperatures of 0-7°C
- Moisture Production: Daily activities generate significant moisture:
- Showering: 1.5L water vapour
- Cooking: 0.5L per meal
- Drying clothes: 2.5L per load
- Ventilation Deficit: 65% of UK homes lack adequate ventilation systems (BRE Group, 2023)
Health & Structural Impacts
- Mould Growth: Begins at 70% relative humidity – 45% of UK rentals report mould issues (Shelter, 2023)
- Respiratory Risks: NHS reports 32% increase in asthma admissions during high-humidity winter months
- Property Damage: Average repair costs for condensation-related damage: £2,800 (RICS, 2022)
