1. What is the UK Energy Bill Calculator?

The UK Energy Bill Calculator helps you estimate your electricity or gas bill based on your energy usage, unit rates, standing charges, and VAT. It provides an accurate calculation following standard UK energy billing practices.

2. How Does the Calculator Work?

The calculator uses the standard UK energy bill formula:

Where:

• \( kWh \) — Energy consumption in kilowatt-hours
• \( Unit\ Rate \) — Cost per kilowatt-hour in pence
• \( Standing\ Charge \) — Daily fixed charge in pence
• \( VAT \) — Value Added Tax percentage

Calculation Steps: Multiply kWh by unit rate, add standing charge multiplied by number of days, then add VAT to get the total bill amount.

3. Understanding Your Energy Bill

Details: UK energy bills consist of two main components: unit rates (cost per kWh used) and standing charges (daily fixed costs). VAT is applied to the total amount at the standard rate of 5% for domestic energy.

4. Using the Calculator

Tips: Enter your energy usage in kWh, your unit rate in p/kWh, daily standing charge in pence, billing period in days, and VAT rate (typically 5%). All values must be positive numbers.

5. Frequently Asked Questions (FAQ)
