5 Reasons UK Businesses Overpay for Gas
Most businesses losing money on gas fall into one or more of these situations.
Rolled onto a rollover or deemed tariff
When a fixed contract expires without renewal, you move automatically to a rollover or deemed rate, one of the most expensive rates available, with no regulatory ceiling.
Accepted the supplier's renewal quote
Suppliers reserve sharpest pricing for businesses actively comparing the full market. Accepting the renewal quote without comparing means paying 15 to 30% more than necessary.
Signed during the 2022 to 2023 crisis
Businesses that fixed rates at the peak of the energy crisis are still locked into historically high unit rates. Wholesale prices have fallen significantly, comparing now could save thousands.
Never switched off the default rate
Businesses that have never compared are on the supplier's default tariff since moving in, often a deemed or out-of-contract rate that can be 50 to 100% above competitive market rates.
Not aware of the renewal window
Most UK commercial gas contracts allow you to agree a new rate 6 to 12 months before the current contract ends. Missing this window means rolling onto expensive default rates automatically.

Business Gas Contract Types Explained
Choosing the right contract type protects your business from overpayment.
Fixed Rate: Most Recommended
Unit rate and standing charge locked for 1 to 3 years. Protects against price spikes. Exit fees £50 to £150/fuel if leaving early.
Variable / Flexible Rate
Moves with market conditions. Can be cheaper when wholesale falls but exposes you to volatility. Best with active energy management.
No Standing Charge
Pay only for gas used. Higher unit rates compensate. Best for seasonal businesses using no gas for months at a time. Limited availability.
Rollover Tariff, Avoid
Auto-renews at inflated rates when your contract ends. Don't wait for a renewal notice, compare at least 3 to 6 months before expiry.

Business Gas Quotes: Special Situations
Different circumstances affect how you compare and switch. Here is what you need to know for each situation.
Multi-Site Businesses
Switch manages multi-site comparisons and can co-ordinate simultaneous switches across all your business premises, pooling total consumption for better unit rates and consolidated single-invoice billing.
Half-Hourly Metered Sites
Businesses with half-hourly (HH) meters have a different switching process and access to different tariff structures. Bespoke quotes are required, call Switch on 01926 942125 to discuss.
Micro-Business Protections
If your business uses under 293,000 kWh of gas per year and employs fewer than 10 people, you are a micro-business under Ofgem rules and qualify for enhanced protections including mandatory renewal notices and additional billing dispute rights.
Green Gas Tariffs
Certified green gas (biomethane) and carbon-offset tariffs are available from several UK commercial suppliers. Switch filters for certified green commercial gas deals in every comparison.
New Premises, Deemed Rate
If your business has just moved into new premises, you are on a deemed rate from day one, typically 30 to 100% above competitive market rates. Compare and fix a contract as soon as possible.
Outstanding Debt
Business energy debt does not automatically block switching. Most suppliers will quote a business with minor outstanding balances. Significant debt may need resolving first, Switch advisors can identify which suppliers will quote in your circumstances.
