Thousands of Britons who have snapped up a 4K television in the Black Friday sale. Or even as a Christmas treat could be facing higher energy bills for using the technology, new research claims.

Energy bills from watching TV are likely to increase for the first time since 2011.  According to British Gas’s latest home energy report, thanks to the latest energy-sapping devices.

Two million UK homes are expected to have a 4K television by the end of the year. 

This figure will rise to nine million by 2019, the research in conjunction with Centre for Economics and Business Research suggests. 

Higher cost: The research from British Gas and Cebr suggests that 4K televisions can use up to a third more energy than an HD one

Greater image clarity via 4K televisions mean they use 33 per cent more energy than an high-definition model. According to a report.

As a result, collectively, people will pay an estimated £82million a year more in 2019 for their electricity bills. 


The report shows that in 2001, the average household spent £14 on powering its TVs for a year. By 2008 it had increased 44 per cent to £20.

This figure declined over the next seven years to £18 – driven by more energy-efficient TVs. But this is set to change in the growth of the 4K market.

Which? describes proper 4k TVs as having ‘so much detail and depth in the picture that it almost feels 3D at times.  You won’t need special glasses to watch it’.


The 4k revolution has taken a while to catch on. 

There aren’t many TV channels in 4k and this is a big challenge, according to experts. Part of the challenge is introducing them onto a subscription-free platform such as Freeview.

Meanwhile, 4k blu-ray players are starting to launch. Some internet video streaming content is available in 4k, such as via Netflix.

However, households will need to have high speed broadband to take advantage.

Some high street retailers may charge £90 for an HDMI cable to ‘make it work.’

But these leads can be bought for far less elsewhere. 

The TVs have a resolution of 3,840×2,160 pixels, more than 8million pixels in total. This, which is four times the number in full HD, which is 1,920×1,080.

The research suggests that 4K TVs use more power than HDTVs because the backlights used in the screens need to be a lot brighter in order to produce more vibrant colours.

A greater amount of energy is also needed for the processing power required to drive the more vibrant imagery.

The report shows that on average, energy consumption from a 4K TV is now more than three times that of a laptop. This is five times that of a games console.

They examined from an energy usage perspective, the total number of 4K TVs in UK households during 2014. These required an additional 11 GWh electricity compared to their HD counterparts.

This equates to £1.8million in higher energy bills around the country.

In 2019, however, this extra energy usage will leap dramatically by 4,264% (to 480 GWh).

Daniel Colford, smart energy expert at British Gas said: ‘TV has long been considered the nation’s favourite pastime. As such people will always look to upgrade to the latest technology to improve their viewing experience.

‘Living rooms now awash with technology and entertainment gadget. Many of these routinely use power even if on standby. We recommend taking a closer look at each device to see how its energy use can be reduced.’

The comprehensive research by Cebr used data from IHS Markit, Natural Resources Defence Council. Also the Department for Business, Energy and Industrial Strategy.

British Gas recommends turning off the TV completely when not in use. In standby mode, they still use a considerable amount of energy.

It also suggests doing your homework when choosing one – an energy efficient model will help keep costs down.

The Energy Saving Trust has developed a website to give a comparison of the country’s most efficient household appliances. This includes televisions.  shoppers may find the top ten most energy efficient models of a number of electrical goods.
