With the rise of holiday homes and short-term rentals like Airbnb, property owners are increasingly asking: “How does seasonal occupancy affect Energy Performance Certificates (EPC)?” Understanding the impact is crucial for compliance, marketing, and energy efficiency planning.
1. How EPCs Are Assessed
EPCs measure a property’s energy efficiency based on heating, insulation, hot water, lighting, and ventilation. Assessors model energy usage based on typical occupancy patterns.
For seasonal properties, this poses unique challenges because:
Energy usage is irregular.
Heating and cooling may only be required for short periods.
Hot water demand fluctuates depending on guest occupancy.
2. Seasonal Occupancy Considerations
Low Occupancy Periods
Properties left unoccupied for long periods may still require:
Minimum heating to prevent damp or freezing pipes.
Maintenance of appliances or ventilation systems.
EPC assessments may assume a baseline energy use, meaning low seasonal occupancy doesn’t automatically improve EPC scores.
High Occupancy Periods
Short-term rentals often experience high energy spikes during stays. EPC modeling may not capture these short-term peaks, but total efficiency measures—like insulation, efficient heating, and smart controls—still influence the rating.
3. Key Factors Affecting EPC Ratings
Insulation & Airtightness: Well-insulated walls, floors, and roofs maintain temperature during both occupied and unoccupied periods.
Heating Systems: Efficient boilers, heat pumps, or zoned heating reduce energy use, even for intermittent occupancy.
Hot Water Efficiency: Instantaneous or on-demand systems help lower unnecessary energy consumption.
Lighting & Appliances: LED lighting and energy-efficient appliances help, but their contribution is modest compared to heating and insulation.
4. Best Practices for Holiday Homes & Airbnb Properties
Install smart thermostats or programmable heating systems to minimize energy use during unoccupied periods.
Schedule maintenance to optimize energy efficiency, such as checking insulation and sealing drafts.
Consider renewable energy solutions, like solar panels, to offset peak seasonal consumption.
Provide energy guidance to guests, encouraging responsible usage.
