Energy bills cover more than just the cost of electricity and gas—you also pay for network maintenance, environmental obligations, and supplier fees. Understanding the differences between gas and electric bills and knowing when to compare energy suppliers can help you reduce costs and avoid overpaying.
In this guide, we’ll break down the key components of gas and electricity bills and share practical tips to help you save money.
What’s Included in Your Gas vs. Electric Bill?
Both gas and electricity bills contain several cost components that affect your overall charges. Below is a breakdown of what you pay for in each bill.
1. Unit Rates (kWh Pricing)
A unit rate is the price you pay per kilowatt-hour (kWh) of energy consumed.
Gas tends to have a lower unit rate than electricity, but you may use more of it for heating.
Electricity has a higher unit rate but is typically used for a wider range of appliances.
Some energy contracts have multiple unit rates, such as off-peak pricing for nighttime use.
Tip: The timing of your contract can affect unit rates. Fixed-rate contracts secure a price for a set period, while variable tariffs fluctuate with market prices.
2. Standing Charges
The standing charge is a daily fee that keeps your home or business connected to the energy network. It covers:
- Maintaining power lines and gas pipes
- Meter readings and billing administration
- Government environmental and social obligations
Even if you don’t use any energy, you still pay this charge. Some suppliers offer tariffs with no standing charge, but these may have higher unit rates instead.
3. Taxes (VAT on Energy Bills)
VAT on energy bills varies based on usage and business type:
Households & Charities: 5% VAT
Most Businesses: 20% VAT
Low Energy Usage Businesses: 5% VAT (if consumption is under 33 kWh/day for electricity or 145 kWh/day for gas)
Tip: If your business qualifies for a reduced VAT rate, ensure your supplier applies the correct rate to your bill.
Additional Costs That Affect Your Gas & Electricity Bills
Beyond basic consumption charges, other factors influence the cost of your energy bills.
1. Wholesale Energy Costs
Energy suppliers buy gas and electricity in advance based on market conditions.
Prices fluctuate due to fuel costs, demand, and geopolitical events.
Suppliers pass these costs onto customers, making timing crucial when locking in a contract.
2. Network Maintenance Costs
Covers the cost of maintaining and upgrading power lines, substations, and gas pipelines.
Includes balancing charges to stabilize energy supply and demand.
3. Environmental & Social Obligation Costs
Your bill includes charges to fund government energy programs, such as:
- Renewable Energy Support (e.g., Feed-in Tariff, Renewables Obligation)
- Carbon Reduction Initiatives (e.g., EU Emissions Trading Scheme)
- Support for Low-Income Households (e.g., Warm Home Discount)
4. Supplier Operating Costs & Margins
Covers customer service, billing, and administrative costs.
Suppliers set profit margins to ensure business sustainability.
