What is business dual fuel?
Dual fuel simply means getting quotes for both your gas and electricity at the same time. Some businesses choose to take both fuels from one supplier for the convenience of a single account and aligned renewal dates; others prefer separate suppliers for each fuel. Comparing both together helps you see all your options.
Our free service passes your enquiry to the partners listed on our Our Partners page, who will contact you with quotes. We're a comparison and introduction service, not an energy supplier.
Benefits of comparing both fuels
Comparing gas and electricity together can help you:
- Line up your contract end dates so you only need to renew once
- Manage your energy from a single account if you choose one supplier
- See the full picture of your energy costs in one go
- Save time with one enquiry instead of two
Fixed vs variable contracts
A fixed-price contract locks in your unit rate (the price per kWh) and standing charge (the daily fee) for the length of your agreement, typically one to five years. Your bills still rise and fall with how much energy you use, but the price you pay per unit stays the same. That makes budgeting simpler and protects you if wholesale prices climb.
A variable or flexible contract tracks the market more closely. Prices can fall as well as rise, which may suit larger businesses with the appetite and expertise to manage risk. For most small and medium-sized businesses, a fixed-price contract offers welcome certainty.
Why your contract end date matters
Business energy contracts don't usually have a cooling-off period, and many renew automatically if you don't act. Your contract end date is when your current agreement finishes. Most suppliers will let you agree a new contract well before that date — often up to 12 months in advance — so you can secure a price early and switch seamlessly when your current deal ends.
If your contract ends without a new one in place, you may be moved onto out-of-contract or deemed rates. These are typically much higher than fixed contract prices. Knowing your end date means you can compare in good time and avoid paying more than you need to.
What affects business energy prices?
Business energy is priced individually rather than from a published price cap, so quotes vary from business to business. Common factors include:
- Wholesale market prices at the time you agree your contract
- How much energy you use each year, and when you use it
- Your location and the network costs for your region
- Your business's credit rating and trading history
- The length of contract you choose
- Your meter type (for example half-hourly or smart meters)
- Government levies and network charges, which are passed through by suppliers
Tips for finding your contract end date
If you're not sure when your contract ends, try the following:
- Look at a recent bill — the end date is often shown on the first or second page
- Check your original contract or the renewal letter your supplier sent you
- Log into your supplier's online account or app
- Call your supplier and ask; have your account number ready
- Not sure? You can still request quotes — the contract end date is optional on our form
