How Much Electric Does a TV on Standby Use

For many households in the UK, leaving appliances on standby has become second nature. Televisions are one of the most common devices left in this state, glowing with a small red light even when no one is watching. With rising energy bills and greater awareness about energy efficiency, it is important to understand exactly how much electricity a TV uses when left on standby, how it affects your overall energy costs, and whether it is worth switching the device off fully when not in use.

Understanding Standby Power Consumption

Standby mode, sometimes called vampire power or phantom load, is a low power state that allows a television to start up quickly or remain connected to the internet for updates. While the TV may appear off, it is still drawing electricity to power internal circuits, remote control sensors, and smart functions. Most modern televisions use far less energy in standby than older models, as they must meet strict EU and UK efficiency regulations. However, even small amounts of power can add up when multiplied across several devices and months of usage.

How Much Electricity Does a TV on Standby Use

The exact electricity consumption of a TV on standby depends on its age, size, and technology. Older plasma models might use as much as 5 to 10 watts in standby, while modern LED or OLED televisions typically use less than 1 watt. At less than 1 watt, the annual consumption is around 8 kilowatt hours if the TV is left on standby continuously throughout the year. With average UK electricity prices around 28 pence per kilowatt hour, this works out to about £2.25 per year for a single television. Although this may seem small, the figure rises if you have multiple TVs or other appliances left on standby.

The Cumulative Effect in Households

While a single TV on standby may not make a huge difference, many homes have several televisions, set-top boxes, game consoles, and smart devices left in standby mode around the clock. When added together, the standby load can amount to 50 watts or more across a property. Over the course of a year, this can use several hundred kilowatt hours of electricity, adding tens of pounds to a household bill. For larger households, particularly those with a lot of entertainment technology, the impact of standby use is worth considering carefully.

Modern Regulations and Efficiency Improvements

The good news for homeowners is that efficiency standards have made a big difference. UK and EU regulations require that televisions and most household appliances use less than 1 watt in standby. Smart TVs with advanced networking features are allowed slightly more, but still far less than older models. Manufacturers have responded with energy saving circuits, automatic power down features, and eco modes that cut unnecessary electricity use. If your TV is more than ten years old, replacing it with a modern model could reduce standby costs as well as improve overall efficiency while in use.

Reducing Standby Electricity Use

If you are concerned about the amount of electricity your TV and other devices use on standby, the simplest solution is to switch them off at the wall. Plug-in timers or smart plugs can help automate this, turning off power completely when not needed. Some households choose to leave smart TVs on standby to allow for software updates, voice commands, or scheduled recordings. In these cases, the energy use is still relatively small, but being aware of the overall effect helps households make conscious choices. Using extension leads with an on-off switch is another easy way to control several devices at once without unplugging them individually.

The Balance Between Convenience and Cost

For many people, the convenience of instant start-up outweighs the small cost of leaving a TV on standby. A modern television costing around £2 a year to keep in standby may not feel like a major concern compared with the cost of running appliances such as tumble dryers or ovens. However, at a time when energy bills are high, every saving matters. By managing standby use across multiple devices, households can cut costs without losing much convenience. It is about finding the right balance between efficiency and practicality.

Final Thoughts

A modern television on standby uses very little electricity, often less than 1 watt, which equates to just a few pounds per year. While this is not a significant drain on its own, the combined effect of multiple devices on standby can raise household energy costs noticeably. Regulations have made modern TVs much more efficient, but turning devices off at the wall or using smart plugs is still the most effective way to eliminate unnecessary energy use. For UK households looking to control bills, understanding and managing standby power is a simple step that contributes to overall energy savings.
