How Much Electric Does a TV Use

Televisions are one of the most common appliances in UK homes, and with energy bills rising, many people are asking how much electricity they really use. The amount of power a TV consumes depends on its type, size, and how often it is switched on. While televisions are generally more efficient today than they were in the past, they can still contribute noticeably to household electricity bills, especially when used for long periods each day.

Different Types of Televisions and Their Power Use

The technology inside your TV plays a big part in how much energy it uses. Older plasma televisions are known for being power-hungry, often consuming between 200 and 400 watts depending on screen size. In contrast, modern LED and OLED models are far more efficient, often using between 30 and 100 watts for average-sized screens. LCD televisions fall somewhere in the middle. Screen size also matters, as a larger display requires more power to operate. For example, a 55-inch LED TV might use twice as much electricity as a smaller 32-inch model, even if both are from the same brand and year.

How Usage Patterns Affect Electricity Consumption

The way a household uses its TV has just as much impact as the type of television itself. A family that watches television for several hours each evening will naturally use more electricity than a household that watches only occasionally. Streaming high-definition or 4K content may also increase energy use compared with standard definition, as the TV’s processor and display work harder to deliver the higher quality picture. In addition, leaving a TV on in the background when no one is watching can add up to unnecessary electricity consumption over time.

Calculating Running Costs in the UK

To work out how much electricity a TV uses, you can look at its power rating in watts, usually found on the back of the unit or in the manual. Multiplying this by the number of hours it is used each day gives you the total watt hours. For instance, a 70-watt LED TV used for four hours a day would consume around 280 watt hours daily, which equals just over 100 kilowatt hours across a year. With average UK electricity prices around 28 pence per kilowatt hour, this means the annual cost of running that TV would be roughly £28. While this may not seem excessive, it becomes more significant when multiple TVs are used around the home.

Standby Power and Hidden Consumption

Even when switched off, most televisions still use a small amount of electricity in standby mode. This powers remote control sensors, timers, or network connections. Modern TVs are designed to use less than one watt on standby, which usually adds up to only a few pounds per year. However, if your household has several TVs and other devices such as set-top boxes and games consoles left on standby, the total hidden electricity use can become more noticeable on your bill.

The Role of Energy Efficiency Standards

UK and EU regulations have played a big role in reducing the amount of electricity TVs consume. Manufacturers must ensure their products meet strict efficiency standards. As a result, the average power use of a television today is far lower than a decade ago, even as screen sizes have increased. Many TVs now come with energy labels that show their estimated yearly consumption, which helps buyers compare models before making a decision. Eco modes and automatic brightness controls are also designed to reduce electricity use without affecting picture quality too much.

Practical Steps to Reduce TV Electricity Use

For households looking to cut costs, there are simple steps that can help manage how much electricity a TV uses. Switching the television off at the wall when not in use eliminates standby power completely. Adjusting brightness settings, using eco mode, and avoiding leaving the TV on as background noise can all make a difference. If you are considering upgrading, choosing a modern LED or OLED model with a good efficiency rating can save energy in the long term. Using smart plugs or timers can also help manage electricity consumption more effectively, particularly in homes with multiple devices.

Final Thoughts

A modern television is not the biggest energy consumer in a household, but it does contribute to overall electricity costs, particularly when used for long periods. The exact amount depends on the type of TV, its size, and how often it is used. While a single LED TV may only cost around £25 to £40 per year to run, larger plasma or older models can cost considerably more. By being mindful of usage habits and making use of modern energy saving features, households can keep costs under control while still enjoying their favourite programmes.
