Business Energy Contract Renewal: What to Do Before Your Contract Ends
Independent guidance on reviewing your commercial electricity and gas contract before it expires — from Free Energy Help.
If your business energy contract is approaching its end date, start by checking the contract end date, any notice or termination requirements, your current supplier, annual consumption and supply details. You can then compare renewal and switching options before agreeing a new contract. What happens at the end of a business energy contract depends on the individual contract terms.
I need to renew my business energy contract — where do I start?
Working through these steps before your contract ends will help you understand your current position and the options available to your business.
Find your contract end date
Check your current energy contract document or your most recent bill. Your contract end date is the single most important piece of information — everything else depends on it.
Check any notice or termination requirements
Your contract may include a notice period — a window during which you must inform your supplier of your intention to switch or renew. Notice periods vary by supplier and contract; check your contract terms carefully.
Gather your latest electricity and gas bills
Your bills contain the key information you will need to compare options: your current unit rates, standing charges, annual consumption, and supplier account details.
Confirm your MPAN and/or MPRN where available
Your Meter Point Administration Number (MPAN) for electricity and Meter Point Reference Number (MPRN) for gas uniquely identify your supply points. These are shown on your bill and are required by suppliers when providing contract options.
Check annual consumption and current supplier
Note your annual electricity consumption (in kWh) and annual gas consumption (in kWh or cubic metres) from your bills. Confirm which supplier currently holds each supply.
Compare renewal and alternative supplier options
With your contract details and consumption figures to hand, you can compare what your existing supplier is offering at renewal against options from other suppliers. An independent broker can help you access a broader range of options.
Review the contract terms before signing
Before agreeing a new contract, check the unit rates, standing charges, contract length, notice period, rollover clauses, and any exit terms. Make sure the contract suits your business before you commit.
Rollover, Out-of-Contract and Deemed Contracts: What Is the Difference?
These three terms are sometimes used interchangeably, but they describe different situations. Understanding the distinction matters for your business.
Contract Rollover
A rollover occurs when your existing contract includes an automatic rollover clause. If you do not give notice of your intention to switch or renew within the specified window, your supplier may automatically extend your contract for a further fixed term — often on new rates set by the supplier. You remain on a fixed-term contract, but one you may not have actively agreed to. Always check your contract for rollover clauses and the notice period required to prevent one.
Out-of-Contract Rates
If your contract expires without renewal or rollover, you move onto your supplier's out-of-contract rate. This is a variable rate set by the supplier, typically higher than negotiated contract rates. You are not locked into a fixed term and can switch at any time, but the rates you pay while out of contract may be significantly higher than those available on a new fixed-term contract.
Deemed Contracts
A deemed contract applies when a business takes supply at a premises without having agreed a contract — for example, when moving into new premises where a supply is already active. Deemed contract rates are set by the supplier and are generally higher than negotiated rates. They are intended to be temporary. If you are on a deemed contract, you can switch to a negotiated contract at any time.
Why Contract Renewals Matter
Understanding what happens at renewal — and what can go wrong — helps your business stay in control of its energy costs.
Automatic Rollover Clauses
Some commercial energy contracts include an automatic rollover clause. If you do not actively renew or switch before the notice deadline, your supplier may automatically roll you onto a new contract term. Reading your contract terms carefully is essential to understand whether this applies to your supply.
Out-of-Contract Rates
If your contract expires without renewal or rollover, you will move onto your supplier's out-of-contract rate. These rates are set by the supplier and are typically higher than negotiated contract rates. Avoiding out-of-contract rates should be a priority for any business approaching its contract end date.
Notice Periods
Commercial energy contracts often include notice periods — a window during which you must inform your supplier of your intention to switch or renew. Missing this window can lock you into a further contract term with your existing supplier. Notice periods vary by supplier and contract; check your contract terms.
Wholesale Market Conditions
The rate your business is offered at renewal is influenced by wholesale energy market conditions at the time you negotiate. Wholesale gas and electricity prices fluctuate based on global supply and demand, seasonal factors, and other variables. Businesses that compare the market in good time are better placed to make an informed decision.
Planning Ahead
Businesses that plan their energy renewal in advance have more options and more time to compare than those that act under time pressure. Starting your renewal review early gives you the best opportunity to make an informed decision — the right lead time depends on your individual contract and switching window.
When Should You Start Your Renewal Review?
The right time to begin depends on your individual contract — including the switching window, notice requirements, and any exit terms. Acting early gives your business more time and more options.
Starting early gives you the most flexibility. You have time to understand your contract terms, check your switching window, compare options across the market, and consider different contract structures without time pressure.
Ofgem notes that fixed business energy contracts normally have a switching window that opens a few months before the contract end date. Check your contract to confirm when your window opens and what notice is required.
If your contract end date is approaching, check your notice period and switching window immediately. Time pressure can limit your options and affect decision-making — act promptly once you have confirmed your position.
If your contract is ending very soon, contact us as soon as possible. We will review your position and do everything we can to help you understand your options and avoid moving onto an out-of-contract rate.
