Why is my electricity bill higher than last month?
Month-on-month jumps usually come from more usage, more billed days, a catch-up after estimates or a tariff change. The fix is to compare the kWh, reading type and days billed before you compare the pound total.
The month-on-month method
- Put the two bills side by side.
- Compare kWh, billed days and reading type.
- Then compare the tariff rates and standing-charge subtotal.
This is the fastest way to see whether the change is coming from usage, timing or pricing.

When the latest bill is the one that matters less
If the previous statement was estimated or unusually short, the latest “higher” bill may actually be the more accurate one. That is why month-on-month comparison needs context, not just instinct.

Frequently asked questions
Can a longer bill period alone make the bill higher than last month?
Yes. More billed days can increase the total even if your daily pattern barely changed.
What should I compare first?
kWh, days billed and reading type.
Does a higher direct debit mean the latest bill was higher too?
Not necessarily. They are linked but not the same thing.
