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.

With consumer spending declining and OFGEM raising their price cap, you would be forgiven for seeing February as a month where negative news was at the forefront, but in the energy markets, this was not the case.

In a year that began with falling energy prices, there were recurring catalysts that led to prices climbing steadily higher. Geopolitical uncertainty and the perennial threat of escalating conflicts meant fear would maintain a constant presence in the wholesale markets. We will look back at the key energy stories from 2024, and how the energy markets are likely to shape up in 2025. Quarter 1  The year began with cautious optimism as the UK’s gas reserve levels were healthy and prices for the Summer’24 season were in freefall. In February, prices pulled back to their lowest levels since 2021, and for the first time in a while, we identified that there was greater potential for upside risk than for further downward price movement: “ there now (exists) an asymmetrical element of risk should the market encounter a supply-side problem of significance. ” During February we had advised customers on flexible contracts that this was an ideal time for making purchases. March would see prices begin to ascend again as international conflict would create problems with LNG imports, and we would highlight the geopolitical risks as an area for concern moving forwards: “ fears remain and there are potential negative catalysts that could lead to prices rising further, with the main factors to watch out for being based on geopolitical unrest. “ For a business that purchases their energy in advance, this quarter was the optimal time for purchasing during 2024. In February, electricity prices for Winter’25 were down to 7.75p/Kwh, and as low as 6.05p/Kwh for Summer’25. Winter’25 ended the year with prices above 11.1p/Kwh, with Summer’25 prices exceeding 9p/Kwh. For a company that uses 500,000Kwh of electricity per month, the difference between buying at the February low point compared to today’s prices would represent a yearly saving of over £200,000.
