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

A smart meter is a digital energy meter that automatically records your gas and electricity consumption and sends readings directly to your supplier. Unlike traditional meters, you won’t need to manually read your meter or estimate bills—everything happens automatically.

Smart meters offer several benefits for UK households. You’ll get real-time visibility of your energy usage, which can help you identify where you’re wasting energy and make adjustments to reduce your bills. Many people find that seeing their consumption in pounds and pence encourages them to be more conscious about energy use. Additionally, smart meters eliminate estimated bills and provide accurate charging based on actual consumption rather than supplier guesses.

The government and Ofgem have made smart meter installation a priority, and all energy suppliers in the UK are required to offer them to customers free of charge.

Are Smart Meters Really Free?

Yes, smart meters are completely free to install and free to own. Your energy supplier cannot charge you for the device itself, the installation, or any ongoing maintenance. This is a requirement set by Ofgem, the energy regulator.

However, you may pay slightly more for your energy if you’re on Economy 7 or other specific tariffs, as the meter itself is more sophisticated. But the meter hardware and fitting costs nothing. Don’t be suspicious if your supplier offers them free—it’s the law that they must.

Some companies may try to sell you additional services alongside smart meter installation, such as home energy audits or upgrade packages. These are optional and not part of the free smart meter offering.

How to Request a Smart Meter Installation

Getting a free smart meter is straightforward. Here’s how to arrange one:

• Contact your current supplier directly. Ring the number on your energy bill, visit their website, or pop into a local branch if they have one. Ask to book a smart meter installation appointment.
• Provide your details. You’ll need your account number, current address, and contact information. The supplier will check your eligibility and confirm whether you have a suitable installation location.
• Book a convenient time slot. Most suppliers offer flexible appointment windows, typically in two-hour slots during working hours. Some suppliers now offer weekend and evening appointments—ask about these if daytime doesn’t suit you.
• Prepare your home. Make sure you have clear access to your meter and that someone aged 18 or over will be present during the installation.

What Happens During Installation?

The installation process usually takes between 30 minutes and two hours. An engineer from your supplier (or a contractor working on their behalf) will visit your home and replace your existing meter with a smart meter.

The engineer will explain how to use the in-home display device, which shows your real-time energy consumption. They’ll answer questions about the new system and ensure everything is working correctly before they leave. You don’t need to do anything—the engineer handles the entire process.

Smart meters work for both gas and electricity, and many suppliers will install both at the same appointment if you’re a dual-fuel customer. After installation, your new readings will be transmitted automatically to your supplier, usually daily or weekly depending on your supplier’s setup.

Which Suppliers Offer Free Smart Meters?

All major UK energy suppliers are legally required to offer free smart meters to their customers. This includes:

• British Gas
• EDF Energy
• EON
• Octopus Energy
• OVO Energy
• ScottishPower
• SSE
• Utility Warehouse

Smaller suppliers and regional companies also offer smart meters. Check with your current supplier first—they’re most likely to have appointment slots available quickly. If you’re unhappy with your supplier for any reason, switching to a new one doesn’t prevent you from getting a smart meter; your new supplier will install one free of charge.

What If You’ve Been Waiting a Long Time?

The government initially aimed to install smart meters in every home by 2020, but this deadline was missed. If you’ve been waiting longer than expected, contact your supplier’s customer service team and ask for an update on your installation status.

If your supplier is dragging their feet or repeatedly cancels appointments, you can lodge a complaint with Ofgem. Suppliers are required to make reasonable efforts to offer meter installations, and persistent failures can result in regulatory action.

Making the Most of Your Smart Meter

Once your smart meter is installed, here’s how to maximise its benefits:

• Check your in-home display regularly. Use it to monitor which times of day you’re using the most energy and adjust your habits accordingly.
• Review your bills. With accurate readings, you can spot any unusual spikes in consumption and investigate the cause.
• Compare your usage month-to-month. This helps you track improvements and see the impact of any energy-saving measures you’ve implemented.
• Use the data to switch tariffs if beneficial. If you’re on Economy 7, the smart meter makes it easier to track whether you’re actually benefiting from off-peak rates.

Privacy and Data Security

You might worry about who has access to your energy data. Rest assured that Ofgem has strict data protection rules in place. Your supplier can only use your consumption data for billing and to contact you about your account. They cannot share this data with third parties without your explicit consent. All data transmission is encrypted and secure.
