Reading your electricity smart meter is easy, simply press the "9" key, the end of a pen or pencil is best for this. First off the display reads "IMP KWH" followed by a number for example "0001889.6" which is the number you need to be able to check your usage.
if you have solar panels, the next reading is useful "EXP KWH" is the total electricity exported to grid for example "0000272.4" then a load of other readings which you don'y need.
Reading the gas meter is similar, first it gives you the volume in cubic meters which is again what you need to check your usage, followed by the kWh and other details you don't need
