Business Dual Fuel Contract Types
With UK wholesale prices broadly stable through 2027 to 28, 24 to 36 month fixes are the recommended option for most UK SMEs. The right choice depends on your usage profile, cash flow, and risk appetite.
Fixed-rate 24 to 36 Month
Cheapest blended option with stable wholesale. Best for most SMEs. Exit fees apply mid-contract. Price certainty for financial planning.
Fixed-rate 12 Month
Slightly higher unit rate vs 24 to 36m but lower exit fee exposure. Best for short-term premises and high-growth SMEs.
Variable-rate
Rolling monthly. No exit fees but bills move with wholesale market. Very short-term needs only. Not recommended for most businesses.
Green Dual Fuel
100% REGO-certified electricity + biomethane gas. Minimal 0 to 1p/kWh premium. Ideal for ESG-focused, B Corp, and public sector organisations.
6 Key Benefits of Business Dual Fuel Energy UK
Why UK SMEs choose dual fuel over managing separate gas and electricity contracts.
Single Monthly Bill
One invoice covering both fuels reduces reconciliation time and simplifies accounts payable, valuable for small finance teams.
One Renewal Date
No costly out-of-contract rollovers from missed notices. Dual fuel aligns both renewal dates in a single agreement.
Single Point of Contact
Billing disputes, smart meter queries, and change-of-tenancy all go through one supplier. No bouncing between separate account teams.
Potential Combined Discount
Some suppliers offer 2 to 5% combined discount. Switch verifies whether the bundled deal beats the sum of the cheapest separate contracts.
Price Certainty on Both Fuels
Fixed-rate dual fuel locks both gas and electricity rates for the full term, complete cost certainty for financial planning.
Green Dual Fuel Options
Renewable-matched dual fuel tariffs increasingly available. REGO electricity + biomethane gas with minimal 0 to 1p/kWh premium.

Yes. UK business energy switching carries multiple Ofgem-enforced protections. Every supplier on the Switch platform is fully Ofgem-licensed.
Who Should Choose Business Dual Fuel Energy?
Dual fuel is not right for every business. Here is who benefits most: and when separate contracts work better.
Best suited: SMEs with single premises
Maximum billing simplicity for small teams. Offices, retail units, restaurants, warehouses, light industrial.
Best suited: Hospitality and food service
High combined gas and electricity demand. One-bill management simplifies complex energy usage patterns.
Separate may be better: Multi-site businesses
Large industrial users (150,000+ kWh/year per fuel) and businesses where gas/electricity cheapest suppliers differ by over 1p/kWh typically save more with separate contracts.
