Your old gas meter and smart upgrades

An old gas meter can raise questions about accuracy, safety, and replacement options for homeowners and tenants. While your energy supplier is responsible for the gas meter they provide to your property, ensuring it is safe and accurate, understanding its condition and upgrade paths is key. This guide explains what an old gas meter is, potential issues it might present, your rights regarding its maintenance and replacement, and how upgrading to a modern smart meter can offer greater control over your energy use.

If you're looking to upgrade your old gas meter to a smart meter and take control of your energy, Fuse Energy offers a modern, digital-first experience. Click here to switch to Fuse Energy today.

What is an old gas meter?

An old gas meter is typically a traditional, mechanical meter that requires manual readings. Unlike modern smart meters, these older models do not automatically send readings to your energy supplier, often featuring a clock-like dial display or a numerical roller display that needs to be read in person.

Identifying your gas meter type

You can usually identify your gas meter by its appearance and functionality. Traditional meters will have a series of dials or a mechanical display that you read yourself, and you will likely receive requests from your supplier to submit readings periodically. Smart meters, on the other hand, usually have a digital display and automatically send readings to your supplier, eliminating the need for manual submissions. They often come with an in-home display (IHD) that shows your energy usage in near real-time.

The evolution of gas meters

Gas meters have evolved significantly since their invention. Early models were purely mechanical, designed simply to measure volume. Over time, they became more refined, but the fundamental principle of manual reading remained for decades. The most significant leap came with the introduction of smart meters, which integrate digital technology to provide automated readings, detailed usage data, and two-way communication with energy suppliers. This shift moves away from legacy metering technology, much like the phasing out of the Radio Teleswitch Service (RTS) for older electricity meters, which began on 30 June 2025.

Concerns with having an old gas meter

While many old gas meters function perfectly well, they can present several challenges compared to their modern counterparts.

Accuracy issues and estimated bills

One of the primary concerns with old gas meters is the potential for inaccurate readings or estimated bills. If you are not submitting regular meter readings, or if there is a fault, your supplier might estimate your usage, which can lead to overpaying or underpaying for your energy. This can result in unexpected catch-up bills or a build-up of credit you were not aware of. Consistent, accurate readings are crucial for managing your energy consumption effectively.

Potential safety considerations

Although rare, very old or poorly maintained gas meters can pose safety risks. Gas meters handle a flammable substance, so any issue with the meter itself, such as a leak or damage, needs immediate attention. Energy suppliers are generally required to replace faulty or unsafe meters at no direct cost to the customer. If you ever smell gas or suspect a leak, you should contact the National Gas Emergency Service immediately on 0800 111 999.

Lack of modern features

Old gas meters lack the advanced features that smart meters offer. They do not provide real-time energy consumption data, making it difficult to understand how much gas you are using and when. This absence of information can hinder efforts to manage energy usage more efficiently and budget effectively.

Your rights and responsibilities

Understanding who is responsible for your gas meter and what you can do if you have concerns is crucial.

Who owns and maintains your meter?

Your energy supplier is responsible for the gas meter they provide to your property. This means your supplier is responsible for the installation, maintenance, and eventual replacement of that meter. You are responsible for providing safe access to the meter for readings, maintenance, or replacement, and for ensuring the meter itself is not tampered with.

Requesting an accuracy check

If you believe your old gas meter is inaccurate, you have the right to request an accuracy check from your energy supplier. Ofgem, the energy regulator in Great Britain, sets the rules for energy suppliers regarding meter accuracy, maintenance, and replacement. Your supplier will arrange for an engineer to test the meter. If the meter is found to be faulty, your supplier will typically replace it and may adjust your past bills. If the meter is found to be accurate, you might be charged for the test.

The gas meter replacement process

If your old gas meter needs replacing, either due to a fault, age, or as part of a smart meter upgrade, the process typically involves your energy supplier.

Contacting your energy supplier

The first step is always to contact your current energy supplier. Explain your concerns about your old gas meter, whether it is about accuracy, safety, or simply a desire to upgrade. They will guide you through their specific process for meter inspections or replacements.

What to expect during a replacement

When a replacement is scheduled, a qualified engineer will visit your property. They will safely disconnect the old meter and install the new one. This process usually takes a few hours, during which your gas supply will be temporarily turned off. The engineer will ensure the new meter is working correctly and safely before restoring your supply.

Addressing a faulty gas meter

If your gas meter is found to be faulty, your energy supplier is generally required to replace it at no direct cost to you. They will also investigate how long the meter has been faulty and may adjust your past bills to reflect accurate usage. This ensures you only pay for the energy you have actually used.

Upgrading to a smart meter

Upgrading from an old gas meter to a smart meter is a significant step towards modern energy management. Energy suppliers are obliged to offer and install smart meters to their customers as part of the nationwide rollout.

Benefits of a smart gas meter

Smart meters offer numerous benefits over traditional models. They send automatic readings to your supplier, eliminating estimated bills and the need for manual submissions. They also provide real-time data on your energy consumption, often via an in-home display or an app. This transparency allows you to see exactly how much gas you are using and helps you identify ways to save energy.

How a smart meter empowers you

Upgrading to a smart meter with Fuse puts you in control of your energy usage and billing. Fuse's app provides clear, real-time data from smart meters, moving away from estimated bills and the uncertainty associated with old meters. This empowers you to make informed decisions about your energy consumption, rather than operating with a "use less" mindset born from scarcity. It is a power play, giving you the capability to manage your energy effectively.

The simple upgrade process

Getting a smart meter is straightforward. Contact your energy supplier to arrange an installation. The installation is typically free of charge, as suppliers are rolling out smart meters across Great Britain to replace older, traditional meters. An engineer will install the new meter, and often an in-home display, explaining how it works. You can also learn more about the smart meter installation process.

Taking control of your energy

Moving from an old gas meter to a smart meter is more than just a replacement; it is an opportunity to gain control and transparency over your energy.
