Just like domestic energy, the best rates are usually offered to new customers. If you signed up to a fixed rate business energy tariff and the plan has ended or ends soon, you could be automatically rolled onto a new contract. This contract might not offer the best value for you, so it’s important to shop around.

If you moved to a business premises without agreeing a contract with a supplier, you might be on a deemed contract. These types of business energy contract are on average 80% more expensive than negotiated contracts, so you could make significant savings by running a business energy comparison and switching.
