What does my (UK) gas meter actually measure?
In the UK, your gas meter measures the volume of gas used by your home or business in a given time period. It is typically located outside and near your property's entrance, where it receives fuel from a local utility supplier.

The gas meter consists of two parts: a valve and a sender unit. When you use gas appliances, such as a stove or boiler, the gas flow meter measures the amount of gas that enters the house and turns on the gas supply to the appropriateappliances. The sender unit sends a signal to your electricity supplier, which records the usage information in your electricity bill.

As an example, if the volume of gas used during a particular hour is higher than what your meter indicates, this could indicate that there may be a problem with the gas supply line, such as a leak or blockage. Your electrician can check the lines for any problems and fix them if necessary. Alternatively, you might also notice that your water or heating bills are more expensive than usual, which could indicate a leak or other issue with your plumbing system. In either case, it's important to have your gas meters checked regularly so you can ensure safe and efficient operation of your appliances and systems.
