Why Compare Dual Fuel?
Dual fuel means taking both your gas and electricity from the same supplier under one plan. While it’s not always the cheapest in every case, it often simplifies your bills and can unlock competitive pricing compared with taking separate single-fuel tariffs.
Key benefits
- One supplier, one bill, one point of contact
- Potential savings versus standard variable rates
- Access to green and smart-ready tariffs
- Convenient account management and online billing
Good to know
- Prices depend on your region, usage, meter type and payment method
- Fixed tariffs provide price certainty for a set term; early exit may incur fees
- Variable tariffs can move up or down with wholesale and regulatory changes
- Standing charge (p/day) + unit rate (p/kWh) together determine your total cost

Understanding Dual Fuel Tariffs
Fixed vs Variable
Fixed tariffs lock in unit rates and standing charges for a set term (e.g., 12 months). Early termination fees may apply. Variable tariffs can change, typically with notice from your supplier.
Payment & Meter Type
Monthly Direct Debit often attracts the most competitive pricing. Tariffs may differ if you have a smart meter, Economy 7 (multi-rate), or prepayment meter.
Green Energy
Some plans match your electricity with renewable certificates or source a portion of gas from green alternatives (e.g., biomethane). Check the supplier’s fuel mix and green policy.

Smart Meters and Prepayment
Smart meter tariffs
Some dual fuel tariffs are designed for smart meters, enabling half-hourly reads, accurate billing and optional time-of-use rates. If you don’t have a smart meter, many suppliers can arrange an installation at no extra upfront cost, subject to availability.
Prepayment (Pay As You Go)
Prepay customers can compare too. If you have outstanding debt with your current prepayment supplier, specific rules may apply and switching might be possible within certain limits. Always check the latest supplier and regulatory guidance at the time of switching.
