Read articleWhat out of contract and deemed business energy rates are, why they cost more, the renewal rules that protect small businesses and how to avoid them.

When a fixed business energy contract ends and nothing new is agreed, your supplier does not cut you off. Instead it moves you onto its out of contract rates, and for many small businesses that is where bills jump.
Below we explain what out of contract and deemed rates are, why they cost so much, the rules that protect small businesses and the simple steps to avoid them.
Out of contract rates are the prices your supplier charges once your fixed term ends without a renewal or switch. They are sometimes called rollover, default or variable business rates.
Because there is no price cap for business energy, suppliers set these rates themselves. They are usually well above the rates on a new fixed contract, and they can change at short notice. A business that ignores its renewal letter can end up paying far more for exactly the same energy.
Deemed rates apply when you use energy at a premises with no contract at all. This usually happens when you:
Like out of contract rates, deemed rates are among the highest a supplier charges. If you have just moved in, contact the supplier straight away and compare deals rather than staying on deemed prices.
| Out of contract rates | Deemed rates | |
|---|---|---|
| When they apply | Your fixed contract ends with no new deal | You use energy with no contract in place |
| Typical cause | Missed renewal date | Moving in or taking over a business |
| Cost | Usually higher than a new fixed deal | Usually the highest rates on offer |
| How to get off them | Agree a new contract or switch supplier | Agree a contract or switch supplier |
Ofgem has extra protections for microbusinesses, which broadly means firms with fewer than 10 employees and a turnover or balance sheet under €2 million, or that use a relatively small amount of energy.
Larger businesses have fewer protections, so the details in your own contract matter even more.
The most common reasons we see are simple:
You can usually move to a new fixed deal at any time, as out of contract tariffs rarely have exit fees. The sooner you act, the less you pay. Compare business electricity and business gas prices, or see what typical business electricity rates look like today.

They are the prices a supplier charges when your fixed business energy contract ends and no new contract is in place. They are usually much higher than the rates you could get on a new fixed deal.
Out of contract rates apply when your fixed contract ends with your current supplier. Deemed rates apply when you use energy at a premises without any contract, for example after moving into new premises. Both are usually the most expensive rates a supplier offers.
For microbusinesses, a supplier can only roll you onto a new fixed contract if it sent you the renewal terms in time and you did not tell it you wanted to leave. Any automatic rollover is limited to a maximum of 12 months.
Start as soon as you know your contract end date. Many suppliers will quote up to a year ahead, which gives you time to compare and to fix a price when the market is favourable rather than in a rush.
No. Unlike household energy, business energy contracts usually have no cooling off period, so check the rates, length and notice terms before you agree.
