Calculator

Calculator notes:

Multi-tariff Functionality: Works for both Standard Variable-rate tariffs that change according to market conditions as well as those with fixed-rate tariffs (i.e. homes who locked their electricity rates until 2024).

Not for multi-rate tariffs: Does not work with multi-rate tariffs (e.g. Economy 7, Time-of-use Tariff) that vary periodically within the day according to peak and off-peak supply and demand.

Energy Price Cap: We use the latest (01 April 2024 – 30 June 2024) Energy Price Cap figures –which we painstakingly compiled from official sources– to auto-fill your unit rate and standing charge for standard variable tariffs.

VAT: We include the reduced 5% VAT charged on all home energy bills to make sure you’re aware of all charges on your bill.

Customisable calculation period: We let you choose the calculation period because suppliers provide your electricity consumption (in kWh) at different time periods depending on your meter type, and households may keep their electricity usage records using different time periods, depending on their preference and again, their type of meter.

Updates: This calculator was last updated in April 2024. The Energy Price Cap figures are due for revision on 30 June 2024.

Limitations: Note that any electricity bill calculations beyond this Price Cap period (1 April – 30 June 2024).

In this section, we answer some frequently asked questions regarding your typical electricity costs in the UK!

How much is electricity in the UK?

This will depend on many things, but the three factors with the most weight on your bill are (1) your electricity use, (2) your tariff, (3) your electricity rate, standing charge and payment option.

According to our simple electricity cost calculator, a typical couple living in a studio flat in Liverpool expects to consume 1,000 kWh of electricity over October, November and December 2023 and pay the maximum unit rate and standing charge according to the most recent Energy Price Cap by Direct Debit, should expect to pay around £338.56.

If they were paying by credit, this would be as much as £359.89, and if they were living in London instead of Liverpool, they’d be paying as little as £318.90.

This shows the large difference in rates depending on where you live and how you pay!
