Gas usage

Can I have my smart metre checked ?

You can have it checked but if found to be not faulty then you will be billed for it.
What do you think is wrong with it?

I think you’ll need to switch to a smart foot first.

If you want the meter calibration checked, contact Bulb directly using the contact information in the help pages and ask. If it turns out there is no problem, you’ll be charged for the check service. What makes you think your meter is wrong?
