When Should I Begin My Renewal Tender?
When Should I Begin My Renewal Tender?
For UK businesses, timing is one of the most important factors when it comes to energy procurement. One of the most common mistakes is leaving your renewal tender too late. Starting the process at the right time can be the difference between securing a competitive contract and being forced into a suboptimal deal.
Why timing matters
Energy prices are driven by wholesale markets that move daily. If your contract is approaching its end and you haven’t begun engaging the market, you risk being exposed to limited supplier options, reduced negotiating power, and potentially higher prices.
Suppliers typically price contracts based on forward market conditions, and the closer you get to your contract end date, the fewer options you may have. In some cases, businesses that fail to act in time can roll onto out-of-contract or deemed rates, which are often significantly more expensive than contracted pricing.
How early should you start?
As a general rule, businesses should begin thinking about their renewal tender 6 to 12 months before their contract end date.
This window allows enough time to:
- Monitor market conditions and identify favourable buying opportunities
- Engage multiple suppliers
- Review contract structures (fixed vs flexible)
- Align procurement with your business strategy and risk appetite
For larger or more complex energy users -- such as those with half-hourly meters or multiple sites -- starting even earlier can be beneficial, particularly if you are considering a flexible procurement strategy or aligning various meters to have the same contract and billing dates.
What happens during a renewal tender?
The renewal process begins with gathering accurate data, including your consumption history, current contract details, and site information. This data is used to approach suppliers and obtain pricing based on your business profile.
From there, quotes are compared on a like-for-like basis, ensuring all unit rates, standing charges, and additional fees are properly assessed. Timing the market then becomes a key factor, as prices can change daily.
Once the right opportunity is identified, contracts are secured.
The risks of leaving it too late
Delaying your renewal tender can limit your ability to act strategically. You may be forced to accept prices at a single point in time, rather than choosing when to lock in. This removes flexibility and increases exposure to market spikes.
Late tenders can also reduce supplier engagement. Some suppliers may be less willing to quote close to contract end dates, particularly for larger or more complex portfolios, or if the market is in a particularly volatile moment.
