Smart meters were first invented in 1974 as a means of managing and tracking energy consumption. Fifty years later, government and industry experts view them as a key tool to keep consumer costs down and tackle climate change.

As the rollout of smart meters ramps up, what better time to collate the definitive UK smart meter statistics report? This page will cover the number of smart meters installed in the UK, the government rollout scheme, and survey results sharing how the UK public feels about smart meters.

Top UK smart meter statistics for 2024

  • Almost all domestic smart meters (99%) are installed by large energy suppliers.

  • More than a quarter (28%) of non-domestic smart meters in the UK are installed by small energy suppliers.

  • Between Q1 2019 and Q3 2023, the number of smart meters in the UK more than doubled (+114%).

How many smart meters are installed in the UK? 

At the end of September 2023, there were 33.9 million smart and advanced meters in UK homes. Statistics indicate that the number of smart meters in the UK has steadily increased since they were first rolled out in 2008. More than 800,000 homes had installed a smart meter since the energy crisis began in the summer of 2021, and the numbers since they have continued to rise. 

Number of domestic smart meters in the UK

According to the latest data from 2023, more than 32 million domestic smart meters are installed in the UK, compared to just 24.2 million in Q1 2021.

Between Q1 2021 and Q1 2022, the number of smart meters increased by nearly a quarter (24%) from 21.7 million to 26.9 million. Q1 2022 was the first time there were more smart meters in the UK than non-smart meters.

Throughout 2022, the number of UK smart meters grew by 12%, while the number of non-smart meters fell by 10%.

UK smart meter rollout

The UK government first announced its intention to mandate suppliers to install smart meters in 2008. A full smart meter rollout would enable consumers to actively keep track of their energy usage to help reduce costs. In turn, this would help raise consumer awareness and reduce consumption as part of the wider net zero strategy for reducing the impacts of climate change. 

In 2011, the government set out a vision for every home and small business in Great Britain to have a smart meter by 2019. In 2012, it placed a legal obligation on suppliers to take all reasonable steps to install smart meters in all homes. However, the 2019 target has since been pushed back to 2025.

UK government smart meter rollout installation targets 

As of 2023, the government remains short of its 2025 target, with just 60% of homes equipped with a smart meter, and the deadline has been described as “not helpful” by a deputy director of the industry's trade body.

In 2012, just 1% of all households had a smart meter. This figure doubled to 2% in 2013 before staying stagnant in 2014.

By 2015, the percentage of homes with a smart meter had shot up to 6% before almost doubling to 11% in 2016. The figure came close to doubling again as, in 2017, the percentage reached 19%.

In 2019, take-up rose again by 52%, growing from 19% in 2017 to 37%.

2021 was the first year in which more than half of all meters were smart meters. Take-up rose five percentage points in 2022 to 55%.

Our smart meter data shows that incorrect energy meter readings are rare. Less than one in 20 (95.4%) smart meters fitted in the UK provided incorrect readings to their energy supplier.

By having a higher level of accuracy, smart meters mean you’re only being charged for the energy you use. Providing you keep up-to-date with your payments, this means your less likely to get into debt with your energy supplier as you’re not being hit with potentially large, estimated bills or future energy back billing.

Before having a smart meter fitted, many people feared that having one fitted would cause their bills to go up. However, our survey data suggests that this is not the case.

With around one in 20 (5.6%) reporting a rise in average energy bills since the installation of a smart meter, this shows that the vast majority of UK residents with a smart meter should see their energy bills go down or remain the same as a result of installing a smart meter. 

UK energy statistics indicate that the average combined energy bill in Q1 2023 was £2,654, and represented a rise of more than three-quarters (77%) from the average annual cost for 2022. Smart meters can help become one part of the solution to help customers reduce their energy bills and help save money.
