The end of a business electricity contract is one of the most important and most misunderstood moments in managing energy costs. What happens at that point can either keep your business on a competitive rate or quietly move it onto one of the most expensive rates available. Many businesses lose money simply because they do not understand or act on this moment. This guide explains what happens when your business electricity contract ends and how to handle it well.
The Moment That Decides Your Rate
A fixed business electricity contract locks your rate for its term. When that term ends, the fixed rate ends too, and what happens next depends entirely on whether you have arranged a new deal. If you have, you move smoothly onto your new contract. If you have not, your supplier moves you onto a default arrangement, and that default is rarely in your favour.
This makes the end of a contract a decision point, even if you do nothing. Doing nothing is itself a choice, and usually an expensive one. Understanding this is the key to avoiding the most common and avoidable overpayment in business energy.
Deemed and Out of Contract Rates
When a contract ends without a new one agreed, a business is typically moved onto a deemed or out of contract rate. These are the supplier’s default rates for customers without a contract, and they are usually considerably higher than a negotiated deal. They exist to cover the supplier’s position for customers who are, from its point of view, unaccounted for, and they are not designed to be competitive.
A business can end up on these rates simply by missing its renewal, and can stay on them for months without realising, paying a premium the whole time. This silent overpayment is entirely avoidable, but only if the business understands that letting a contract lapse leads straight to it.
Renewal Windows and Notice
Business electricity contracts often involve a renewal window, a period before the end date within which you can arrange your next deal. Some contracts also have notice requirements. Understanding your contract’s terms tells you when you can act and what you need to do to avoid either rolling onto a default or being tied into another term unintentionally.
Missing the window is how businesses get caught. If you leave it too late, your contract ends and you fall onto a deemed rate. This is why knowing your end date and any notice period, and acting within the window, is so important. It is the difference between choosing your next rate and having an expensive one chosen for you.
What to Do Before Your Contract Ends
The right approach is to act in good time. A couple of months before your contract ends, gather your recent bills and compare the market. Comparing through a service such as business electricity comparison lets you see current rates matched to your usage, so you can identify a competitive new deal. Agree your new contract within the renewal window, and you move straight onto it when the old one ends, never touching a default rate.
This preparation turns the end of a contract from a risk into an opportunity. Instead of drifting onto an expensive default, you use the moment to secure a fresh competitive rate, which is exactly what the end of a contract should be: a chance to review and improve, not a trap.

If You Have Already Rolled Onto a Default
If your contract has already ended and you are on a deemed or out of contract rate now, the priority is to act promptly. Every month on a default rate is likely an overpayment, so comparing the market and moving onto a proper contract as soon as possible stops the bleeding. Because deemed rates usually do not tie you in, you can generally switch away from them without the constraints of a fixed term, so there is no reason to stay a moment longer than necessary.
Frequently Asked Questions
What happens when my business electricity contract ends?
If you have arranged a new deal, you move onto it. If not, your supplier moves you onto a default deemed or out of contract rate, which is usually much more expensive.
What is a deemed or out of contract rate?
A supplier’s default rate for customers without an agreed contract. It is typically considerably higher than a negotiated deal and is not designed to be competitive.
What is a renewal window?
A period before your contract end date within which you can arrange your next deal. Acting within it lets you move onto a new contract rather than rolling onto a default.
How do I avoid rolling onto a default rate?
Know your end date, compare the market a couple of months before it, and agree a new contract within the renewal window so you move straight onto it when the old one ends.
What if I am already on a default rate?
Act promptly. Compare the market and switch to a proper contract as soon as possible. Deemed rates usually do not tie you in, so there is no reason to stay on one.
Final Thought
The end of a business electricity contract decides your rate, whether you act or not. Do nothing, and you drift onto an expensive deemed rate. Act in good time, compare the market, and agree a new deal within your renewal window, and you secure a fresh competitive rate instead. Understanding this moment, and preparing for it a couple of months ahead, is one of the simplest and most valuable habits in managing business electricity costs.
