cost of energy at Bulb

Why is the actual cost of my Bulb supplied electricity so much more than the estimate? i was very precise with the usage levels i gave… and now i am paying 15% more than i did with my previous supplier!
i will be moving my supply

Are you saying you are paying 15% more per kWh ?
When did you join as prices have risen?
Usage levels are not fixed they fluctuate based on your usage.

When you sought an estimate did you enter your previous 12 months annual usage in kWh or purely on the size and type of your home?

It sounds like you’re confusing your monthly payment with the bill. They are not the same.

Check your unit cost (pence per kWh) and daily standing charge (pence per day) before moving supplier.
