Choosing the right electricity contract is an important decision for any business. Prices can change quickly, suppliers offer different terms, and the cheapest-looking quote is not always the best option once all charges are considered.
A business electricity tender helps businesses compare the market in a structured way. Instead of relying on one renewal offer, it allows suppliers to compete for your contract based on price, terms and overall value.
This guide explains how the electricity tender process works, what information is needed, and how businesses can avoid common mistakes when procuring electricity.
A business electricity tender is the process of asking multiple energy suppliers to provide prices and contract options for your electricity supply.
Businesses usually do this when an existing contract is coming up for renewal, when they are moving premises, or when they want to check whether their current supplier is still offering good value.
The aim is not just to find the lowest unit rate. A good tender compares the full contract, including standing charges, payment terms, contract length, pass-through costs and supplier service levels.
A business should usually go out to tender before its current electricity contract ends. Leaving this too late can reduce the number of options available and may increase the risk of moving onto expensive out-of-contract or rollover rates.
Tendering can also be useful when a business is growing, opening new sites, changing its energy usage, or reviewing costs across multiple locations.
For high energy users, timing is especially important. Market conditions can change quickly, so starting the process early gives the business more time to compare options and make a better decision.
The electricity tender process usually starts by gathering key information about the business. This includes electricity usage, meter details, contract end dates and any specific requirements.
Once the information is ready, suitable suppliers are invited to quote. The offers are then compared based on price, terms and suitability. This stage may also involve asking suppliers questions, clarifying charges and checking whether any conditions apply.
After the preferred supplier is chosen, the contract is reviewed and signed. The new supplier will then manage the switch or renewal process so the new agreement starts at the right time.
Suppliers should be compared on more than price. While the unit rate is important, it is only one part of the overall cost.
A proper electricity supplier comparison should also look at standing charges, contract length, payment terms, renewable energy options, pass-through charges, customer service and renewal conditions.
For some businesses, flexibility may also matter. A multi-site business, for example, may need aligned contract end dates, consolidated billing or support across different meter types. The best supplier is not always the cheapest on paper, but the one that offers the best overall fit.
To start an energy contract tender, businesses usually need recent electricity bills, annual consumption data, meter point numbers, current contract end dates and site details.
For larger or more complex sites, half-hourly data may also be useful. This gives a clearer picture of when electricity is being used and can help suppliers price the contract more accurately.
It is also important to understand the business requirements before going to market. This could include contract length, green energy preferences, budget priorities, payment terms or plans for future growth.
One of the most common mistakes is leaving the tender too late. If there is not enough time to compare suppliers properly, the business may end up accepting a poor renewal offer or falling onto expensive default rates.
Another mistake is comparing only the unit rate. A contract with a lower unit rate may still cost more overall if the standing charges, pass-through costs or terms are less favourable.
Businesses can also overlook contract end dates, notice periods and renewal terms. This can lead to missed deadlines, automatic renewals or less control over future procurement decisions.
The length of a business energy tender depends on the size and complexity of the business.
For a simple single-site business, the process may be relatively quick if all the information is available. For multi-site businesses, high energy users or sites with complex meters, the process can take longer because there is more data to review and more supplier questions to resolve.
As a general rule, businesses should avoid waiting until the final weeks of a contract. Starting early gives more time to gather data, compare offers, negotiate terms and avoid rushed decisions.
Many businesses choose to use an energy procurement consultant because the commercial electricity market can be difficult to navigate.
A consultant can manage the tender process, approach suppliers, compare quotes, review contract terms and explain the options clearly. This can be especially useful for businesses with multiple sites, high usage or limited internal time.
Procurement support can also help businesses look beyond the headline price. The right consultant will consider contract structure, risk, supplier suitability and long-term cost management, not just the cheapest quote on the day.
