1. What is the UK Energy Price Calculator?

Definition: This calculator estimates the cost of electricity usage based on appliance power, usage time, and current energy rates.

Purpose: It helps UK residents understand and predict their electricity costs for better budgeting and energy conservation.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( \text{Cost} \) — Total cost in pounds (£)
• \( P \) — Power consumption in watts (W)
• \( t \) — Time in hours (h)
• \( \text{Rate} \) — Electricity rate in pounds per kilowatt-hour (£/kWh)

Explanation: The formula converts watts to kilowatts (by dividing by 1000) then multiplies by hours and the rate to calculate total cost.

3. Importance of Energy Cost Calculation

Details: Understanding energy costs helps in budgeting, identifying energy-hungry appliances, and making informed decisions about energy usage.

4. Using the Calculator

Tips: Enter the appliance power in watts, usage time in hours, and current electricity rate (default £0.34/kWh). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Where can I find my appliance's power rating?
A: Check the label, manual, or manufacturer's website. Typical examples: LED bulb (10W), laptop (50W), fridge (200W), kettle (3000W).

Q2: What's the current UK electricity rate?
A: As of 2023, the average is about £0.34/kWh but check your energy provider for exact rates as this varies.

Q3: Can I calculate daily/monthly costs?
A: Yes, enter the total hours used per day/month or multiply the result by the number of days.

Q4: Does this include standing charges?
A: No, this calculates usage costs only. Standing charges are fixed daily costs from your provider.

Q5: How accurate is this calculator?
A: It provides estimates. Actual costs may vary based on real-world usage patterns and tariff structures.
