How to Choose the Right Business Energy Supplier

The right supplier fits how your business uses energy. Check these points before you sign.

  1. 1Compare the Full CostThe unit rate is only part of your bill. Ask for the standing charge and any levies, then compare the total annual cost rather than the price per kWh alone.
  2. 2Pick the Right ContractA fixed contract locks in your rate and makes budgeting easier. A flexible contract follows the wholesale market, so it can save money when prices fall but costs more when they rise.
  3. 3Check Your MeterConfirm the supplier supports your meter type, whether traditional, smart or half-hourly. Use real readings from the last 12 months rather than estimates.
  4. 4Confirm Green ClaimsIf renewable supply matters to you, look for electricity backed by REGO certificates. Also check whether it is the default or a paid add-on.
  5. 5Review Support and Exit TermsCheck whether support runs 24/7 or only in office hours. High exit fees can trap a growing business, and a missed renewal date can move you onto costly out-of-contract rates, so note your end date and start comparing several months ahead.

Find the Supplier That Fits Your Business

Every business uses energy differently, so the best supplier is the one that suits how you work, not just the one with the lowest quote. Choose two or three names from the table, compare real prices side by side and read the contract terms carefully before you commit. A little time spent now can save you a lot over the length of your contract.

Frequently Asked Questions

1Is there a price cap on business energy?

No. Unlike household energy, business energy has no price cap. Suppliers set their own prices from wholesale market costs, your usage, location and contract length, so rates can change daily and quotes differ between businesses.

2Can I switch business energy supplier before my contract ends?

Yes, but your current supplier may charge an exit fee for leaving early. It is often cheaper to wait until the contract ends, so compare the fee against what the new deal would save you. Once you agree a switch, it usually takes around three weeks, and your supply is not interrupted.

3Is there a cooling-off period for business energy contracts?

Most business energy suppliers do not offer one, unlike household contracts. That makes it important to check the price, length and terms before you agree, because you may not be able to cancel without a cost.

4What happens if my business energy supplier goes bust?

Your gas and electricity should keep flowing while your account is moved to a new supplier. Do not switch tariff or supplier until that transfer is complete, and check the new terms once it happens.

5Why is business electricity so expensive?

The energy itself is only part of the bill. Network, environmental and other non-commodity costs make up a large share of electricity bills, and wholesale prices, your usage and your contract length all affect the rate you pay.
