When should I renew my business energy contract?
Short answer
Start looking at your business energy renewal 6 to 12 months ahead of contract end. Most UK B2B suppliers will let us lock in pricing up to 12 months in advance. Waiting until the contract end-window risks auto-rollover to deemed or out-of-contract rates, which are typically 30 to 50% more expensive than negotiated tariffs.
