Do Garage Doors Use a Lot of Electricity in the UK?

For many UK homeowners, the garage door is an integral component of daily life, providing security, convenience, and even aesthetic appeal. As the trend towards electric and automated garage doors grows, a question emerges: How much electricity do these doors consume? In a world increasingly conscious of energy usage and sustainability, it’s a valid concern. In this article, we’ll break down the electricity consumption of garage doors and what that means for the average UK homeowner.

Understanding the Basics

First, it’s important to note that garage doors are not continuous power consumers like refrigerators or heating systems. They draw power when in operation, which, for most households, is just a few minutes each day.

Standby Power

Most electric garage door openers consume a small amount of electricity even when not actively operating, known as standby power. This power keeps the remote sensor active, awaiting the signal to open or close. However, this consumption is relatively minimal.

Operational Power

The bulk of electricity consumption occurs during the door’s operation. Factors affecting this include:

  • The size and weight of the door.
  • The type and efficiency of the motor.
  • The duration the motor runs (affected by door speed and height).

“Garage door openers don’t run constantly; they’re intermittent consumers of power.”

How Much Electricity Does an Average Garage Door Consume?

To understand consumption, we must break down the components of a typical electric garage door system.

Standby Consumption

Modern garage door systems use between 5 to 8 watts in standby mode. This equates to:

  • 120 to 192 watts per day (considering 24 hours).
  • Approximately 44 to 70 kWh per year.

Operational Consumption

A typical garage door motor is rated between 500 to 750 watts. Assuming a door takes 20 seconds to open or close, a single operation would consume:

  • Approximately 0.0033 to 0.0042 kWh.

If the door operates four times daily (twice open, twice close), the yearly consumption would be:

  • 4.8 to 6.1 kWh annually.

Combining both standby and operational power, an average electric garage door in the UK might use between 48.8 to 76.1 kWh annually.

How Does This Affect Your Electricity Bill?

Now that we’ve discussed raw consumption, what does this mean for your wallet?

Let’s use the average cost of electricity in the UK, which, as of my last update, is approximately 14.4p per kWh.

  • For 48.8 kWh, the annual cost would be £7.03.
  • For 76.1 kWh, the annual cost would be £10.96.

“While the operation of an electric garage door does have a cost, it’s relatively minor in the context of a household’s overall electricity bill.”

Reducing Electricity Consumption

For those keen on cutting energy costs further:

  • Upgrade to energy-efficient openers: Some modern garage door systems are designed with energy conservation in mind.
  • Regular maintenance: Ensuring your garage door is well-maintained reduces operational times and potential strains on the motor.
  • Turn off the system during vacations: If you’re away for extended periods, disconnect the opener from the power source.


Garage doors, while electrical, aren’t significant energy consumers, especially when viewed in the broader context of household appliances and systems. The convenience they offer far outweighs the minimal costs associated with their operation. However, with conscious choices and regular maintenance, homeowners can further reduce this already small footprint, aligning with both economic and environmental objectives.
