What Is a Smart Meter and Why Should You Get One?

A smart meter is a modern gas and electricity meter that automatically sends readings to your energy supplier, eliminating the need for manual meter readings. Unlike traditional metres, smart metres transmit usage data digitally, typically via a secure wireless network, allowing you to monitor your consumption in real-time through an in-home display.

Getting a smart meter installed is one of the best decisions you can make for managing your energy bills. By understanding exactly how much energy you’re using and when, you’ll be better positioned to identify where you’re wasting money and adjust your habits accordingly. Many UK households report saving between £11 and £35 per year simply by becoming more aware of their consumption patterns.

Are Smart Meters Really Free?

Yes, smart meters are completely free to install under UK law. Ofgem, the energy regulator, requires all energy suppliers to offer free smart meter installations to eligible customers. You won’t pay for the metre itself, the installation labour, or any subsequent maintenance related to the smart meter’s operation.

However, it’s important to note that smart meters won’t automatically reduce your energy bills. They provide the information needed to help you make better decisions about your usage, but the savings come from your own behaviour changes. Some suppliers may offer incentives or rewards for upgrading to a smart meter, so it’s worth checking with your provider.

Who Is Eligible for a Free Smart Meter?

Nearly all UK households and small businesses are eligible for a free smart meter. Your eligibility depends on a few basic criteria:

• You have a standard domestic electricity and/or gas supply
• Your property is accessible for installation
• You’re not in a high-rise flat above the 10th floor (these present technical challenges with wireless signals)
• You’re a customer of a participating energy supplier

If you live in a flat above the 10th floor or in a building with unusual structural features that might prevent signal transmission, contact your supplier directly to discuss alternative options. Some suppliers have developed workarounds for these situations.

How to Request a Free Smart Meter Installation

Step 1: Contact Your Current Supplier

The easiest way to arrange your free smart meter is to contact your current energy supplier directly. Most major suppliers, including British Gas, EDF, E.ON, Octopus Energy, and Scottish Power, are actively rolling out smart metres across their customer bases. You can request installation through:

• Your supplier’s website (usually under the ‘My Account’ section)
• Their customer service phone line
• Their mobile app if they offer one
• In writing to their customer services department

Step 2: Book Your Installation Slot

Once you’ve requested a smart metre, your supplier will contact you to arrange a convenient time for installation. The process typically takes between 30 minutes and 2 hours, depending on your property layout and whether you have both gas and electricity metres to upgrade. Make sure someone is at home during the appointment, as the installer will need access to your metres and to set up your in-home display.

Step 3: Prepare for Installation Day

Before your appointment, ensure the installer can safely access your metres. Clear any obstructions and make sure the area is well-lit. If you have pets, consider confining them to another room to prevent any disruptions during installation.

What Happens During Installation?

On installation day, a qualified engineer from your supplier’s approved contractor will arrive to install the smart metre(s). They’ll replace your existing metre with a new smart metre and provide you with an in-home display device. This display shows your real-time energy consumption in pounds and pence, helping you understand which appliances are using the most energy.

The installer will explain how to use the device and answer any questions. They’ll also provide information about your new smart metre and how to access your usage data online through your supplier’s portal.

Switching Suppliers with a Smart Meter

One common concern is whether switching suppliers will affect your smart meter. The good news is that smart metres are designed to work with any licensed supplier in the UK. However, when you switch, your new supplier may need a period to establish the connection—sometimes a few weeks. During this time, you might revert to sending manual readings temporarily, but this is a brief inconvenience for the savings you could make by switching.

Always compare energy tariffs before switching. You might find better rates with a different supplier, which could lead to savings far exceeding the modest benefits of awareness alone.

Maximising the Benefits of Your Smart Meter

To get the most from your smart meter, check your in-home display regularly and look for patterns in your usage. Most suppliers also offer online portals where you can view detailed breakdown of consumption by appliance and time of day. Use this information to:

• Identify energy-hungry appliances and replace them with more efficient models
• Adjust your usage patterns to avoid peak times if you’re on a time-of-use tariff
• Detect unusual spikes that might indicate a fault
• Set consumption targets and track progress

What If Your Supplier Hasn’t Offered a Smart Meter Yet?

All suppliers are required to have rolled out smart metres to all eligible customers by the end of 2025, though many are ahead of schedule. If your supplier hasn’t contacted you yet, don’t wait—reach out to them proactively. Getting your smart metre sooner means you can start benefiting from better energy awareness immediately.

If you’re unhappy with your current supplier’s pace or service, switching to a supplier that’s already completed their smart metre rollout could be worth considering.
