When Should I Renew My Business Energy Contract?

The best time to renew depends on when your contract ends and market conditions at that time. Generally, Summer and early Autumn often offer lower rates than Winter. However, wholesale prices are constantly changing. Our timing tool predicts when your renewal window is opening based on your contract end date, so you can act strategically rather than reactively.

Waiting for your supplier's renewal letter means you're accepting their timing and their renewal rates. By then, you've already missed the opportunity to shop around or lock in better rates earlier. Proactive renewal gives you control — you can compare suppliers before receiving an offer and secure better deals on your terms.

Most suppliers allow you to fix rates up to 12 months in advance of your contract end date. However, contracts fixed too early may not give you the best price — you want to lock in rates during a favourable market window, typically 3–6 months before your end date. Our timing tool helps you identify the optimal window to fix rates.

If you miss your renewal window and your contract expires without a new deal in place, you'll roll onto out-of-contract rates. These are significantly higher — often 30–50% more than fixed rates — and can cost your business thousands monthly. This is why timely renewal is critical. Our reminders help you never miss this deadline.

Yes, you can switch suppliers before your contract ends. Your new supplier will typically arrange for the switch to happen on your contract end date, so there's no gap or overlap. This is often the best strategy — you exit your current contract on schedule and start your new contract immediately with better rates locked in.

Historically, Summer and early Autumn often see lower wholesale prices than Winter because energy demand decreases. However, this isn't guaranteed — wholesale prices depend on global factors like fuel costs, weather forecasts, and geopolitical events. That's why we track live market data to identify the best renewal window for your specific contract end date, regardless of season.

Energy prices are driven by wholesale commodity costs (gas and electricity prices on global markets), supply and demand, fuel availability, weather forecasts, and geopolitical factors. Business energy contracts are typically fixed for 12 months, so your renewal rate reflects the market price at the time you lock in. This is why timing matters — locking in during a lower market cycle saves significantly.

No, you don't need to upload a bill. We only need your contract end month and year to predict your renewal window and provide personalised timing advice. If you later decide to get a quote for a new contract, we may ask for additional details like your annual consumption, but the timing tool requires minimal information.

Our renewal timing tool and market insights are completely free. We only earn a commission if you decide to take out a new energy contract through us, which is transparent and declared on all quotes. This commission is typically lower than if you went directly to suppliers, so you save money compared to contacting them independently.
