When Shouldn't I Switch?

Honesty is our policy. While most businesses benefit from switching, there are two scenarios where you should stay put:

1. High Exit Fees

If your current contract has hefty penalties for early termination that outweigh the potential savings of a new deal.

2. Binding Contracts

If you're already in a low-rate fixed contract that doesn't expire for another 12+ months, market rates might currently be higher.

Understanding Business Energy Tariffs

Not all business energy contracts are created equal. Here are the main types you'll encounter.

Fixed Rate

Lock in your unit price for 1–5 years. Offers budget certainty regardless of market fluctuations.

Variable Rate

Prices track the wholesale market. Can be cheaper when market drops but risky during price spikes.

Deemed Rates

Applied when you move into new premises without a contract. Usually the most expensive option.

Out-of-contract

Default rates when your fixed term ends and you haven't switched. Can be double standard rates.

Half-Hourly (HH)

For high-energy users. Meter sends usage every 30 mins for highly accurate billing.

Green Tariffs

Energy matched by 100% renewable sources like wind or solar. Great for CSR goals.

Can't Switch Just Yet?

If you're still in contract, here are 3 things you should do right now to prepare.

Diarise It

Mark your contract end date and renewal window. We can set a reminder for you.

Meter Readings

Submit monthly readings to ensure your current bills are accurate and not based on estimates.

Track Usage

Identify patterns in your energy consumption to see where you can implement efficiency measures.

Business Energy FAQs

Business energy FAQs

Comparing quotes takes under a minute. The switch itself usually completes within two to four weeks once your new contract is agreed, though it can vary by supplier. We handle the transfer and the paperwork, so there's very little for you to do.

Usually not mid-contract without paying an exit fee — business energy generally can't be switched partway through a fixed term. But you can almost always line up your next deal in advance and have it start the day your current one ends. Tell us your contract end date and we'll make sure you don't roll onto expensive rates.

These are the most expensive rates a supplier charges. You land on out-of-contract rates when a fixed deal ends and nobody renews it, and on deemed rates when you move into premises without agreeing a contract. If you're on either, you're almost certainly overpaying — and switching should be your next move.

No. The Ofgem price cap only protects household customers. Business energy prices are set entirely by your contract, which is exactly why comparing matters even more for a business than it does for your home — two firms on the same street can pay very different rates for identical usage.

Not at all. The same gas and electricity flow into your premises — only the company billing you changes. There's no interruption, no engineer visit and no rewiring. The new supplier manages the switch behind the scenes.

Just the basics to start: your business postcode and roughly what you spend or use. To lock in an accurate quote it helps to have a recent bill handy, as it shows your meter details and current rates — but you can begin with just a postcode.

Business energy is contracted differently: there's no price cap, gas and electricity are usually separate contracts with separate end dates (so no "dual fuel"), contracts tend to run one to five years, and you generally can't switch mid-term. It sounds more complex, but it's exactly why getting the right deal up front saves so much.

Our comparison service is free for you. When you switch to a deal through us, the supplier pays us a commission — it never affects the price you're offered, and you never pay us anything.
