Electricity Bill Calculator FAQ
How do I find my kWh usage?
Check your electricity meter reading or recent bill. For monthly usage, take readings 30 days apart and subtract. Smart meters show daily/weekly usage in the display or app.
What is the current electricity unit rate?
Under the Ofgem price cap (Q1 2026), electricity costs 24.50p per kWh plus a standing charge of 60.10p per day. Fixed rate tariffs may offer different prices depending on the length and supplier.
How can I estimate future electricity bills?
Use your average monthly kWh usage from the past 12 months and apply current rates. Consider seasonal variations - winter bills are typically 20-30% higher due to increased lighting and heating.
