What is a smart meter?

A smart meter is an electricity or gas meter that can automatically send your meter readings to your energy supplier. If you have a smart meter, you’ll no longer have to remember to take and send manual meter readings each month. And your bill will always be based on real readings rather than estimates, making it more accurate. 

How do smart meters save energy?

Smart meters run on a tiny amount of electricity – just 1kWh over an entire year. But the information they provide could help you save much more than that by having more control over your energy.   

Because you can see how much energy you’re using in real time, as well as track your usage over the past day, week or month, you’ll be able to easily see the impact of energy saving actions. Making simple changes like turning down the temperature on your boiler, or swapping to LED bulbs, can all make a difference to your bill.

How do smart meters help the environment?

 As well as helping you save energy, smart meters are key building blocks for a more flexible, efficient energy system.  

By providing a clearer picture of how much energy is used throughout the day, smart meters help energy suppliers and the National Grid match supply and demand more closely. This means the grid will be better able to make the most of energy from renewable sources, rather than relying on big fossil fuel generators.  

The information that smart meters provide will also enable energy suppliers to offer more flexible types of tariff, which will support people to use clean technologies such as electric vehicles and heat pumps.
