Power Usage in Most Homes
Understanding Power Usage in Most Homes (kVA)
In residential settings, power is typically measured in kilovolt-amperes (kVA), which represents the apparent power in an electrical system. Most houses in the UK use between 9-12 kVA of power, depending on the size of the property and the number of appliances being used.
Here are a few common factors that can affect a home’s power requirements:
Household Size: Larger homes with more rooms and more electrical devices will generally need higher kVA levels.
Electrical Appliances: High-consumption appliances like electric ovens, heating systems, air conditioning units, and electric showers can significantly increase the power demand.
Energy-Efficient Devices: Homes with energy-efficient appliances and lighting typically consume less power, meaning lower kVA requirements.
Here’s a list of common household appliances and their approximate power consumption in kVA. Keep in mind that actual power usage may vary depending on the make and model of each appliance:
Common Household Appliances and Their kVA Ratings

Total Household Power Usage
Most homes, depending on the appliances in use, typically require between 9-12 kVA to run all devices simultaneously, but this can vary based on individual usage and efficiency.
For events or temporary power needs, understanding the kVA requirement is crucial in choosing the right generator size
