What is a smart meter and what does it do?

A smart meter is a next-generation gas and electricity meter that automatically sends your energy readings to your supplier, significantly reducing the need for manual submissions and the likelihood of estimated bills. These devices provide real-time data on your energy usage, and an In-Home Display (IHD) is often provided, giving you greater control and insight into your household consumption. They are a key component in modernising the UK's energy grid, supporting more efficient energy management and offering the potential for savings through informed decisions.

What exactly is a smart meter?

At its core, a smart meter measures the gas and electricity you use, much like a traditional meter. However, its "smart" capabilities go far beyond simply recording a running total.

More than just a meter

Unlike older meters that require someone to physically read them, a smart meter uses a secure data network to send your energy readings directly to your supplier frequently, often daily, and can be set to half-hourly intervals. This automated process ensures you are only billed for the energy you actually use, significantly reducing the likelihood of estimated bills. Smart meters are typically installed for both gas and electricity, often during a single appointment.

The In-Home Display (IHD)

Many smart meter installations include an In-Home Display (IHD), a portable device that shows your energy consumption in near real-time, expressed in pounds and pence. This display updates frequently, allowing you to see how much energy you're using and what it's costing you.

How smart meters work

Smart meters operate through a sophisticated system designed to provide accurate data and enhance communication between your home and your energy supplier.

Automatic readings

The primary function of a smart meter is to automatically measure your gas and electricity usage and send these readings wirelessly to your energy supplier. This secure data transmission means you no longer need to submit meter readings yourself, ensuring your bills are based on actual consumption, significantly reducing the reliance on estimates.

Two-way communication

Smart meters facilitate two-way communication. Not only do they send your usage data to your supplier, but they can also receive information, such as tariff updates or changes between prepayment and credit modes, without needing a physical visit. This connectivity is managed through a secure national communication network, often referred to as the Data Communications Company (DCC) network.

Gas and electricity smart meters

If you have both gas and electricity supplied to your home, you will typically receive a smart meter for each fuel. Your supplier will usually aim to install both meters during the same visit for convenience. The accompanying IHD will then display usage data for both your gas and electricity supplies.

Benefits of having a smart meter

Installing a smart meter offers several practical advantages for households, from clearer billing to greater control over energy use.

Accurate bills

One of the most immediate benefits is the significant reduction in estimated bills. Because smart meters send automatic readings to your energy supplier, you'll only pay for the energy you've actually used. This accuracy helps with budgeting and avoids unexpected charges.

Understanding your energy use

The In-Home Display provides a clear, real-time view of your energy consumption in pounds and pence. This visibility can help you identify energy-intensive habits or appliances, making it easier to understand where your money is going and make informed decisions about reducing usage.

Potential for savings

While a smart meter doesn't automatically save you money, it provides the tools to do so. By understanding your energy usage patterns, you can actively look for ways to reduce consumption. Smart meters also open the door to flexible tariffs, such as time-of-use tariffs, which can offer cheaper rates during off-peak hours or when renewable energy is abundant. Shifting some energy use to these times can lead to potential savings.

Supporting a smarter grid

Smart meters are fundamental to modernising the UK's energy infrastructure. They help the National Grid better understand and manage Britain's energy needs, leading to a more efficient system that can integrate more renewable energy sources. This contributes to a greener, more reliable energy supply for everyone.

Addressing common smart meter concerns

Many households have questions about smart meters, particularly regarding their mandatory nature, data privacy, and what happens when switching suppliers.

Are smart meters compulsory?

No, smart meters are not compulsory. While the UK government has set targets for energy suppliers to offer and install smart meters in homes across Great Britain, you have the choice to accept or refuse the installation. However, if your existing traditional meter is faulty or at the end of its life, your supplier may replace it with a smart meter, as traditional meters are becoming less common.

Data privacy and security

Concerns about data privacy are understandable, but smart meters are designed with security in mind. They record how much gas and electricity you use, similar to traditional meters, and transmit this data securely to your supplier. Your smart meter does not store personal information like your name, address, or bank details; these are linked to your account held by your supplier and are subject to strict data protection laws, including GDPR. Ofgem, the energy regulator, oversees suppliers to ensure they adhere to rules on smart meter operation and data privacy.

What if I switch suppliers?

If you have a smart meter, you can switch energy suppliers without disruption to your energy supply or billing. Modern second-generation smart meters (SMETS2) are designed to switch seamlessly between suppliers, with your meter automatically updating with your new supplier's details. Some older first-generation smart meters (SMETS1) might temporarily lose some smart functionality after a switch, meaning you might need to submit manual readings for a short period, but this functionality is typically restored.

Getting a smart meter for your home

If you're ready to take advantage of the benefits a smart meter offers, the process is straightforward.

Eligibility and installation

Smart meters are installed free of charge by energy suppliers as part of a national rollout programme. To get one, simply contact your energy supplier, who will arrange an appointment for installation at a convenient time. Most homes in Great Britain are eligible.

What to expect during installation

The installation process is usually straightforward. A qualified engineer will replace your old meters with the new smart meters and set up your In-Home Display. They will also show you how to use the IHD to monitor your energy usage. You do not need a broadband connection for the smart meter to work, as it uses its own secure wireless system.

Making the most of your smart meter

Once installed, your smart meter becomes your first "power play" for ultimate energy control. Actively engage with the data it provides through your IHD or your energy supplier's app. Monitor your usage patterns, identify opportunities to reduce consumption, and explore flexible tariffs that reward you for using energy at off-peak times. Fuse Energy's integrated app experience and 24/7 human customer support are designed to help you understand and maximise the benefits of your smart meter data, ensuring a seamless experience as you take control of your energy.

The future of smart energy
