Where:
Explanation: The calculation accounts for both your energy usage and the fixed daily charge that appears on most UK electricity bills.
Details: Understanding your electricity costs helps with budgeting, comparing energy tariffs, identifying energy-saving opportunities, and managing household expenses more effectively.
Tips: Enter your energy consumption in kWh, your electricity rate in GBP per kWh, and your daily standing charge in GBP. You can find these values on your electricity bill or from your energy provider.
Q1: What is a standing charge?
A: A standing charge is a fixed daily amount you pay for electricity, regardless of how much energy you use. It covers the cost of maintaining the energy network and supplying electricity to your property.
Q2: How can I find my electricity rate?
A: Your electricity rate is shown on your energy bill, usually expressed as pence per kWh. Divide by 100 to convert to GBP per kWh for this calculator.
Q3: Are there different tariffs in the UK?
A: Yes, common tariffs include standard variable tariffs, fixed-rate tariffs, economy 7 (with day and night rates), and green energy tariffs. Check which tariff you're on for accurate calculations.
Q4: Does this calculator include VAT?
A: This calculator uses the pre-VAT rates. VAT is typically added at 5% for domestic electricity in the UK, which would be an additional calculation.
Q5: How often should I check my electricity costs?
A: Regular monitoring helps track usage patterns. Consider checking monthly to identify seasonal variations and potential savings opportunities.
