The figure on the rhs of the statement is only an estimate and may not be very accurate.
Here’s what to do
If electricity (gas is different)
find your first PP statement look at the start reading used for electricity start example 15792
find latest statement write down last reading. example 18322
Count the number of statements overall (9 or 10?) say 10
subtract first from second 18322-15792=2530
divide by number of statements, 2530 divided by 10 = 253 then multiply by 12 = 3036kW
Then compare with what statement says.
Do the same for gas using the cubic metre gas readings then multiply the final answer by 11.4, that will be near enough, again compare with statement
(this isn’t perfect, because of where we are in the year it may overestimate slightly )
