Sorry to hear of the issue you had with your gas boiler after getting a smart meter installed, this could be down to an air pocket in your gas pipes.
Whenever there is a disruption to your gas pipes, such as the installation of a new gas appliance or in this case a new meter, there’s a chance that air may enter the system which would affect the gas supply. To prevent this happening our engineers purge your gas system after replacing the meter/ This involves releasing gas into the system, which forces removal of air. Once the air is fully removed, we’re able to relight your appliances.
See advice from Transparent here as well:
If you have a gas cooker @Kolonics.Terez, you could try lighting those burners to "pull" any air pockets out of the internal pipework. They are still likely to work ok.
The reason a boiler is less likely to work is because it has a "flame sensor" which shuts off the gas supply if the flame isn't detected within a few seconds.
Occasionally even after purging, trace amounts of air may remain which later cause a disruption to your supply, as happened in your case. We’d recommend contacting a gas-safe engineer if you experience any issues with your supply following a gas meter installation. An engineer would be able to carry out a full check of your appliances if another purge fails to get things sorted.
I hope once these installation issues have been resolved, you can begin enjoying the benefits of your new Smart Meters.
