Meter readings

I entered the meter readings from my smart meter as a new client to bulb, should I have entered the readings from the gas meter and electric meter and not the smart meter?

Some clarification for you:

The devices physically attached to your incoming electric and gas supply are the smart meters.
The small display device is the In Home Display (IHD).

You need to take the readings from the meters, just like you would do for any other non-smart meter. Depending on the model of In Home Display you have, the raw meter values might be accessible through the display, rather than having to look directly at the meters themselves.

The key point is you need to enter the actual raw meter readings, not whatever your IHD is showing converted to whatever units.
