The problem
Poor renewal timing can leave UK businesses paying more than they need to.
Poor renewal timing, rollover contracts and lack of visibility leave many businesses locked into higher rates, often without realising until it is too late.
Many businesses only review their energy position after renewal deadlines have already passed, reducing flexibility and increasing rollover risk.
Contracts nearing renewal are prioritised for fastest response
Most businesses do not overpay because of price. They overpay because of timing.
If you miss the right window, you can be locked into higher rates for months or even years.

What does a business energy broker do?
A business energy broker helps companies review energy contracts, understand renewal options and avoid poor out of contract or rollover rates.
When should I review my business energy contract?
Most businesses should start reviewing around six months before the contract end date. This gives more time to understand options and avoid rushed decisions.
Can I upload my energy bill for review?
Yes. Uploading a recent bill helps CNG Switch review your rates, usage and contract position more accurately.
Is CNG Switch a comparison site?
No. CNG Switch provides adviser-led business energy support rather than unreliable live-price comparison promises.
What happens if my contract ends?
If no new contract is agreed, your supplier may move you onto rollover or out of contract rates, which can be more expensive.
Is the review free?
Yes. The initial review is free and there is no obligation to proceed.
