What is an old gas meter?

An old gas meter is typically a traditional, mechanical device that requires manual readings. Unlike modern smart meters, these older models do not automatically send your usage data to your energy supplier. They often feature a series of dials or a mechanical display that needs to be read in person, either by you or a meter reader.

Identifying different types of older gas meters

You can usually identify an older gas meter by its appearance. Many have mechanical dials that rotate as gas is consumed, or a simple numerical display that updates manually. Some older meters might be prepayment meters, requiring you to top up a key or card to access gas. If your meter does not have a digital screen that shows real-time usage or is not connected wirelessly to your energy supplier, it is likely an older model.

Distinguishing functional old meters from antiques

It is important to differentiate between a functional old gas meter that is still in use and an antique meter that might be a collector's item. While antique meters are typically very old, often from the early 20th century or before, and are no longer operational, a functional old meter is simply an outdated model that still measures your gas consumption. The key difference is that functional old meters are part of your active energy supply and are subject to replacement programmes, whereas antique meters are not. This guide focuses on functional old meters that are due for an upgrade.

Why upgrade your old gas meter?

Upgrading your old gas meter is not just about getting a new piece of equipment; it is about unlocking greater control and efficiency over your home's energy. Sticking with an outdated meter can lead to several disadvantages, while a smart meter offers numerous benefits.

Implications of keeping an outdated gas meter

One of the primary issues with older gas meters is their reliance on estimated readings. If your energy supplier cannot get a regular actual reading, they will estimate your usage based on past consumption patterns. This often leads to inaccurate billing, meaning you could be overcharged or undercharged for the gas you have used. An estimated bill can cause confusion and may result in a large catch-up bill when an actual reading is eventually taken.

Furthermore, older meters do not provide real-time data, making it difficult to understand how much gas you are using and when. This lack of insight can hinder your ability to manage your energy consumption effectively and identify areas where you could save.

Benefits of a smart gas meter upgrade

Smart meters offer accurate, automatic readings, which means you will only pay for the gas you actually use, eliminating estimated bills. They also come with an in-home display that shows your energy consumption in near real-time, allowing you to track your usage in pounds and pence. This immediate feedback can empower you to make informed decisions about your energy habits.

Smart meters also open the door to modern, potentially cheaper tariffs, such as time-of-use tariffs, which can offer lower rates during off-peak hours. The average UK home uses around 9,500 kWh of gas per year, so understanding and managing this usage can lead to significant savings.

Safety and maintenance considerations

While older gas meters are generally safe if properly maintained, like any mechanical device, they can become less accurate over time. Energy suppliers are responsible for the safety and maintenance of your gas meter. Upgrading to a smart meter ensures you have the latest technology, which can also help in quicker identification of faults and power outages.

Getting a smart gas meter

The good news is that getting a smart meter installed is a straightforward process, and it will not cost you anything upfront.

Eligibility for a smart meter installation

Most UK households are eligible for a smart meter installation. Energy suppliers are mandated to offer smart meter installations to their customers as part of a national government programme. The UK government aims for suppliers to take all reasonable steps to achieve 100% domestic smart meter coverage by the end of 2030.

The smart meter installation process

To get a smart meter, you simply need to contact your current energy supplier. They will arrange a free installation appointment at your convenience. A trained engineer will visit your home to replace your old gas meter with a new smart meter. The installation usually takes a couple of hours, and your energy supply will only be off for a short period.

What to do if your current meter is unsupported

While most meters can be replaced with smart meters, some older electricity meters, such as those using the Radio Teleswitch Service (RTS), are being phased out. The RTS for electricity meters began its industry-wide phase-out on 30 June 2025. It is crucial to note that RTS meters are specifically for electricity and do not apply to gas meters. If you have an RTS electricity meter, your current electricity supplier will need to replace it with a smart meter. Once that is done, you will be able to enjoy the benefits of smart metering for both your electricity and gas.

Managing your energy with a smart meter

A smart meter is a powerful tool for energy management, putting you in control of your consumption and costs.

Real-time data and accurate billing

With a smart meter, you gain access to real-time data on your energy usage through an in-home display and often through your energy supplier's app or online portal. This means no more estimated bills; you will receive accurate statements based on your actual consumption. This transparency allows you to see the impact of your energy choices immediately, helping you to identify where you can make changes to reduce your usage.

Accessing modern energy tariffs

Smart meters enable access to a wider range of energy tariffs, including those designed to reward flexible usage. These can include tariffs with cheaper rates during off-peak hours, allowing you to shift high-energy activities like running washing machines or charging electric vehicles to times when energy is cheaper. This capability is a power play, shifting control and insight over energy usage directly into your hands.

Using the Fuse app for energy control

Once you have a smart meter, platforms like the Fuse app can further enhance your energy management capabilities. The Fuse app provides real-time data, accurate billing insights, and can help you understand your eligibility for dynamic tariffs. This integration allows you to monitor your energy usage on the go, track your spending, and make informed decisions to optimise your energy consumption.
