Gas meters are essential devices used to measure the volume of gas consumed in homes and businesses in the UK. Understanding how gas meters work can help consumers monitor their gas usage, identify potential issues, and ensure accurate billing.
Key Facts
- Gas Flow: The flow of gas always enters the gas meter through the inlet on the left and exits through the outlet on the right.
- Measurement: Gas meters measure the volume of gas used as it flows through the meter. The volume is registered on the meter index, which can be read to determine the amount of gas consumed.
- Types of Gas Meters: There are different types of gas meters used in the UK, including digital metric gas meters, digital imperial gas meters, and dial gas meters.
- Digital Metric Gas Meters: Digital metric gas meters measure gas usage in cubic meters (m3) and usually display ‘m’ or ‘m3’. The numbers before the decimal point are recorded, while any numbers after the decimal point are ignored.
- Digital Imperial Gas Meters: Digital imperial gas meters measure gas usage in cubic feet (ft3) and typically display ‘cubic feet’ or ‘ft’. The four numbers from left to right are recorded, and any numbers shown in red are ignored.
- Dial Gas Meters: Dial gas meters have a series of clock-style dials with numbers from zero to nine. To read the meter, start with the left dial and record the number indicated by the pointer on each dial, moving towards the right. If the pointer is between two numbers, record the lower number. Ignore any red dials.
Gas Flow and Measurement
Gas meters operate on the principle of gas flow measurement. Gas enters the meter through the inlet on the left side and exits through the outlet on the right side. As the gas flows through the meter, its volume is measured and registered on the meter index. The meter index displays the amount of gas consumed in cubic meters (m3) or cubic feet (ft3), depending on the type of meter.
Types of Gas Meters
There are three main types of gas meters commonly used in the UK:
-
- Digital Metric Gas MetersThese meters measure gas usage in cubic meters (m3) and typically display ‘m’ or ‘m3’. To read the meter, record the numbers before the decimal point and ignore any numbers after the decimal point.
-
- Digital Imperial Gas MetersThese meters measure gas usage in cubic feet (ft3) and usually display ‘cubic feet’ or ‘ft’. To read the meter, record the four numbers from left to right and ignore any numbers shown in red.
- Dial Gas MetersDial gas meters have a series of clock-style dials with numbers from zero to nine. To read the meter, start with the left dial and record the number indicated by the pointer on each dial, moving towards the right. If the pointer is between two numbers, record the lower number. Ignore any red dials.
Accurate Readings and Maintenance
Gas meters are designed to provide accurate readings of gas consumption. However, it is essential to ensure that the meter is properly maintained and calibrated to avoid inaccurate readings. Regular inspections and maintenance by qualified gas engineers can help ensure the meter’s accuracy and prevent potential issues.

How do I read my gas meter?
The method for reading a gas meter depends on the type of meter you have. For digital metric and imperial gas meters, record the numbers before the decimal point and ignore any numbers after the decimal point. For dial gas meters, start with the left dial and record the number indicated by the pointer on each dial, moving towards the right. Ignore any red dials.
What should I do if I suspect my gas meter is faulty?
If you suspect your gas meter is faulty, you should contact your gas supplier immediately. They will arrange for a qualified gas engineer to inspect and test the meter to determine if it is faulty. If the meter is found to be faulty, it will be repaired or replaced.
How can I ensure accurate gas meter readings?
To ensure accurate gas meter readings, it is essential to keep the meter clean and free from obstructions. Regular inspections and maintenance by qualified gas engineers can also help ensure the meter’s accuracy and prevent potential issues.
What are the safety precautions I should take when using a gas meter?
Gas meters are generally safe devices, but it is essential to take certain safety precautions. Never attempt to tamper with or modify the gas meter, as this can be dangerous and illegal. If you smell gas, leave the premises immediately and contact the National Gas Emergency Service on 0800 111 999.
How can I reduce my gas consumption and save money?
There are several ways to reduce your gas consumption and save money, such as:
- Using energy-efficient appliances
- Insulating your home properly
- Turning off lights and appliances when not in use
- Taking shorter showers
- Using a programmable thermostat
