Why the Timing of Your Renewal Matters
Most suppliers send renewal letters when prices are at their highest — often in Winter.
By waiting, you can miss cheaper dips that usually appear in the Summer months.
Leaving it late means fewer options, rushed decisions, and less negotiating power.
By planning ahead, you give yourself more chances to lock in a lower rate.
No more last-minute stress — know the best time to act, months in advance.
Your Questions, Answered
We understand energy contracts can be confusing.
Here are answers to the questions businesses like yours ask most often
Why shouldn’t I just wait for my renewal letter?
Most suppliers send renewal letters when the market is at its most expensive — often in Winter. By waiting, you risk fewer options and higher prices. Checking the market earlier gives you more choice and often better rates.
When is the best time to renew my business energy contract?
There isn’t a single “best” date for everyone, but wholesale prices often trend lower in the Summer months (April–September). Our tool helps you see your exact timing window based on your contract, so you can plan ahead.
How far in advance can I lock in a new deal?
Most suppliers allow you to renew up to 12 months before your current contract ends. That means you can often secure a good rate well before your renewal letter even arrives.
What happens if I miss my renewal window?
If you don’t agree a deal in time, you’ll usually be moved onto expensive out-of-contract rates. These can be up to 70% higher than fixed-term contracts. That’s why we recommend acting at least 21 days before your end date.
Can I switch suppliers before my contract ends?
Yes, but you can only agree a new deal that starts once your current one finishes. You won’t be penalised if you time it correctly — your new supplier simply takes over on your contract end date.
Why do energy prices change so much?
Prices are influenced by global gas and oil markets, weather, storage levels, and supply risks. That’s why timing is so important: small shifts in the market can add up to big differences in your renewal cost.
Do I need to upload a bill to use the tool?
No — you’ll get personalised timing advice just by entering your contract end date. If you upload a bill, we can also show you how your current deal compares against the market to see if you’re already paying too much.
Is Summer cheaper than Winter for energy contracts?
As a general rule of thumb — yes. In Winter, energy demand spikes because businesses and households use more gas and electricity for heating. Higher demand plus tighter supply usually means higher prices.
In Summer, demand drops, storage levels are often healthier, and prices tend to ease. Think of it like buying strawberries: in peak season (Summer), they’re abundant and cheaper. Out of season (Winter), they’re scarce and more expensive. Energy markets follow a similar supply and demand cycle.
