How to Find the Best Business Electricity Rates
Gather your details first.
To compare business electricity fairly, you need your annual usage in kWh, your meter’s MPAN (the long number on your bill) and your contract end date. Use a year of bills, so every quote is priced on the same figures.
Look past the unit rate.
A quote with a low unit rate and a high standing charge can cost more overall, especially for a small site. Add both together for a year, and check whether each quote includes VAT and the Climate Change Levy.
Contract ending soon? Line up your next one now
Suppliers can quote ahead of your renewal date, so you can agree your next contract before you move onto out of contract rates. Roo shows quotes side by side with the terms laid out.
When to Compare Business Electricity
Business electricity contracts are not covered by the household price cap, so what you pay depends on the deal you agree. These are the moments when it pays to look.
You have moved premises.
Move in without arranging a contract and you will be on a deemed contract. Ofgem says deemed rates are usually higher than negotiated contract rates.
Your fixed term is ending.
Without a new deal you move onto out of contract rates, which Ofgem says are usually more expensive than fixed term contracts. A rollover contract renews by itself, usually for 12 months, and may be on a higher rate.
Your usage has changed.
New equipment, electric heating, EV charging or longer hours all change your usage, and usage is one of the biggest factors in the price you are quoted.
You want greener electricity.
Many suppliers offer renewable electricity contracts. Ask how the electricity is backed, so you know what you are paying for.
What Affects the Price of Business Electricity
The wholesale price is only part of a business electricity bill. These are the other parts worth checking before you sign.
VAT.
Business electricity is usually charged the standard 20% rate of VAT. HMRC treats very small supplies, no more than 33 kWh a day on average or 1,000 kWh a month, as domestic use for VAT. Ask your supplier which rate applies to you, because the household rate on qualifying electricity in Great Britain is temporarily 0% from 1 October 2026 to 30 June 2027.
The Climate Change Levy.
Business electricity carries the Climate Change Levy, which HMRC sets at £0.00801 per kWh from 1 April 2026. Homes do not pay it.
Contract length and end terms.
Citizens Advice says a business energy contract can last up to 5 years. Check what happens when it ends: renewal, rollover or out of contract rates.
How you agree.
You can agree a business energy contract over the phone or online without signing anything, and there is no cooling off period. Our guide to the best business electricity rates explains what to check first.
Types of Business Electricity Contract
Ofgem lists several types of business energy contract. Not every supplier offers all of them.
Fixed-Rate Tariff
Fixes the unit rate and standing charge for the length of the contract.
Variable-Rate Tariff
Prices can go up or down during the contract, for example as wholesale prices move.
Deemed or Out of Contract Tariff
Starts automatically if you move in without a contract or your supplier goes out of business. It also applies when a fixed term ends without a new deal. Ofgem says these rates are usually higher than a negotiated fixed term contract.
Green Electricity Tariff
Perfect for sustainability focused businesses. Your supplier matches your usage with renewable energy generation or offsets your carbon output.
Rollover Contract
Renews by itself at the end of a fixed term if you have not agreed a new deal, usually for 12 months and possibly at a higher rate.
Flexible Purchasing Contract
Lets a business buy energy in smaller portions over time. Ofgem says these suit large businesses that use a lot of energy.

Does my business get the electricity VAT cut?
The temporary 0% rate runs from 1 October 2026 to 30 June 2027 on qualifying electricity in Great Britain. HMRC treats business supplies of no more than 33 kWh a day on average, or 1,000 kWh a month, as domestic use for VAT. Ask your supplier whether your account qualifies.
