Electricity price per kWh in the UK: what to compare
When people search for “electricity cost per kWh”, they often want one neat number. Real billing is messier. The price you should compare depends on region, payment method, tariff type and the time period of the bill.
Why a single national number misleads
Two households can both be on standard variable tariffs and still see different-looking charges because the comparison context is different. That is why generic “UK electricity price per kWh” articles are weak if they do not explain region tables and tariff periods.

The better comparison method
- Read the unit rate on your bill.
- Check which period the statement covers.
- Check whether the bill spans a tariff change.
- Use the official current region tables if you need external validation.
If the supplier rate looks wrong, ask for the tariff sheet and the rate period applied to your statement rather than arguing with a generic average from elsewhere.

Frequently asked questions
Is there one correct UK electricity price per kWh?
No. Comparison depends on tariff type, payment method, region and time period.
Should I use the price cap figure instead of my bill rate?
Use your bill rate first, then use the cap tables for context if you are on a standard variable tariff.
Why does the total still feel high when the unit rate seems normal?
Standing charge, billed days and usage volume can still drive the total up.
