1. What is the Energy Saving Calculator?

The Energy Saving Calculator estimates potential cost savings by comparing old and new energy consumption levels. It helps UK consumers understand the financial benefits of energy efficiency improvements.

2. How Does the Calculator Work?

The calculator uses the energy savings formula:

Where:

• \( Old\ kWh \) — Previous energy consumption in kilowatt-hours
• \( New\ kWh \) — Current or projected energy consumption in kilowatt-hours
• \( Rate \) — Electricity rate in GBP per kWh

Explanation: The equation calculates the monetary savings achieved by reducing energy consumption at your current electricity rate.

3. Importance of Energy Savings Calculation

Details: Calculating energy savings helps households and businesses understand the financial return on energy efficiency investments, make informed decisions about energy upgrades, and track progress toward sustainability goals.

4. Using the Calculator

Tips: Enter your previous energy consumption (kWh), current or projected consumption (kWh), and your current electricity rate (GBP per kWh). All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Where can I find my electricity consumption data?
A: Check your energy bills or smart meter readings for historical consumption data in kilowatt-hours (kWh).

Q2: How do I determine my electricity rate?
A: Your electricity rate is shown on your energy bill, usually expressed in pence per kWh. Convert to GBP by dividing by 100.

Q3: What are typical energy savings from efficiency measures?
A: Savings vary widely but can range from 5-30% depending on the measures implemented (LED lighting, insulation, efficient appliances).

Q4: Does this calculator account for standing charges?
A: No, this calculator only calculates savings from reduced energy consumption. Standing charges remain constant regardless of usage.

Q5: Can I use this for business energy calculations?
A: Yes, the same formula applies to both domestic and commercial energy savings calculations.
