Compare business gas prices and fix your rates

Whether your small rural restaurant is cooking on gas or you have gas-powered boilers to keep the heating on in a big city office, you don’t want to overpay for business gas. That’s where comparing quotes is key. 

If you’ve not switched business energy suppliers recently, it’s almost certain you’ll be paying more than you need to. Fixing your rates is the only way to protect against price volatility and take control of your energy bills. That’s why it makes sense to compare business gas prices to see if you can find fixed rates that are cheaper than what your current supplier is offering. 

But before you run a business gas comparison, it’s worth learning how the switching process works and what contracts are on offer. There’s usually a bit more to do than when switching home energy suppliers. 

How to compare business gas rates and switch 

Comparing business gas prices is simple when you get some expert help. Just give us your postcode and we’ll use smart data to find out the basics about your business and its energy needs.  

One of our energy experts will then give you a call to fill in any blanks and talk you through the quotes. This is important as there is no cooling-off period on business energy contracts.  You need to be completely happy before you sign, or you’ll be locked into a contract you don’t want. 

MoneySuperMarket partners with Bionic to make sure you benefit from their expert energy advice. Give the Bionic team a call now on 0800 088 6986. Or, if you prefer, give us your postcode, and we’ll give you a call back. 

To save time and hassle, the Bionic energy experts use smart data to learn about your business and its energy needs. But there are sometimes gaps in the data, so it’s good to have the following information ready if you can: 

• The name of your current gas supplier 
• The name of your tariff and its end date 
• How much gas your business uses 

Once Bionic has this information, an energy expert will gather the best business gas tariffs from a panel of suppliers to help you make a more informed decision on what’s best for your business.  

Just let your energy expert know which deal you prefer, and they’ll start the switch.  

If you have a fixed contract with your current supplier, you won’t be able to sign a new deal until your current one is in its ‘renewal window’. And your new contract won’t start until your current one ends. 

If you’re paying your supplier’s out-of-contract rates you can sign up with another supplier at any time and the switch could take as little as five days (depending upon the size of your business). For more information, check out our guide to small and micro business energy. 

Why switch business gas suppliers? 

Unlike with domestic gas contracts, there are no off-the-shelf tariffs for business gas. This is because there are huge differences in how and when businesses use gas and commercial contracts are designed to reflect these differences and meet the specific needs of each business. 

But switching to a better-priced business gas tariff is a quick and easy way to cut costs that won’t impact on the day-to-day running of your business. The gas still makes its way in through the existing pipes, meaning there’s no need for any digging or drilling at your workplace, and there’ll be no interruption to your supply. 

Switching to a new deal also means you can choose the type of tariff you’re on.  

If you move into a new business premises without sorting a new contract, you’ll be placed on deemed rates with the previous occupant’s supplier. 

If you’ve not switched for a while and let your last contract end without lining up a new one, you’ll be on your supplier’s out-of-contract rates. Both deemed and out-of-contract rates are more expensive than the rates you’ll get on a fixed contract. 

Switching to a fixed-rate contract usually means you’ll get the best business gas prices available. This type of contract also protects against price volatility and can help with your monthly budgeting. This is because the costs remain more or less the same (depending upon the amount of energy you use). 

On the other hand, you might prefer a flexible tariff, which could see your energy bills drop if there is a fall in wholesale gas prices, and your supplier passes on these savings. This type of tariff is riskier as your rates will go up if market rates increase. 

One advantage of flexible tariffs is that some allow you to give just 30 days’ notice before switching. This could be ideal if you’re at premises with a short-term lease or run a pop-up shop. If you’re on a fixed tariff, you usually can’t get out of your contract until it expires. 

What are the latest business gas costs in 2025? 

So, what’s the typical cost of business electricity rates per kWh? It depends on how much energy your business uses. Here’s a quick guide to the latest business electricity prices by business size: 

April 2025 business gas usage, rates, and bills

Business size	Average annual usage (kWh)	Average unit rate (per kWh)	Average standing charge (per day)	Average annual bill
Micro business	5,000 to 15,000	7.7p	40.3p	£917
Small business	15,001 to 30,000	7.1p	43.3p	£1,756
Medium business	30,0001 to 65,000	7.2p	54.4p	£3,619
Large business	More than 65,000	8.5p	89.9p	£5,853

_{Note: Prices are correct as of April 2025. Rates and bill size may vary according to your meter type and business location. The prices you’re quoted may be different from the averages shown. The figures shown are the average unit rates and standing charges on contracts sold by Bionic from April 1 to April 7, 2025.}

These are averages, so your actual business gas costs might be higher or lower depending on factors like your location or energy efficiency. 

How to get the cheapest business gas prices 

The first thing you need to know about switching business gas and electricity is that you can’t even consider changing supplier until your current deal is in its renewal window, which usually opens between one and six months before its end date. 

Don’t worry if you’re unsure when this renewal window starts, your supplier will write to you with your contract's end date and an offer to extend your existing deal or a new fixed contract. Don’t accept this offer before you compare quotes to see if cheaper business gas rates are available from another supplier. 

Instead, use this letter as an opportunity to serve notice on your current deal and compare energy plans to find the cheapest business gas supplier.  If you line up a new contract to start when your current one ends, you'll automatically be placed on your supplier’s more expensive out-of-contract rates. 

Once that’s done, get in touch with our energy experts who will compare business gas plans to find a tariff that meets the needs and budget of your business. One call is enough to give our experts the information they need to compare business energy tariffs from our panel of suppliers. 

Once you’ve found a deal that suits, we’ll start the switch and support you through the process. 

What happens when you switch business gas? 

Once you’ve agreed to sign up with a new supplier, you shouldn’t have anything to do until the day of the switch (although your supplier might get in touch beforehand to confirm some details). Remember, your new contract won’t start until your current one ends, so it could take a few months before you start paying your new business gas rates.  

Once your details have been passed to your new supplier, they will then sort out the rest of the switch with your current supplier. 

Your new supplier will send you details of the switchover date and a copy of your energy contract. Be sure to thoroughly check the details, as there’s usually no cooling-off period with business energy contracts. 

When everything is agreed, you’ll just need to take a meter reading on the day of the switch and make sure you’ve paid any outstanding bills. This is important as your old supplier can block your switch if you owe them money. 

What if you run your business from home? 

If you work from home, you won’t be eligible for a business gas deal unless more than 50% of your energy use is for your business. This threshold can vary, between suppliers though, so it’s worth contacting your supplier to find out if a commercial tariff could save you money. 

If you can’t take out a business tariff, just make sure you’re on the best domestic energy deal. 

How can MoneySuperMarket get you cheaper business gas rates? 

We make it easy for you to compare gas quotes from a panel of suppliers, so you can choose the best one for your business. 

Business energy can be complex, and different businesses use energy in different ways and at different times. Costs can vary between suppliers, tariffs, regions, and types of business. To reflect that, quotes are bespoke to each business – and can take a while to gather if you do it yourself.  

Although you might be able to get your gas from the same supplier, dual fuel tariffs aren’t available. This means you’ll need to sort a separate business electricity contract. Ringing around several suppliers to compare rates can be time-consuming as you’ll need to repeat your details to each supplier. If you use both gas and electricity, you’ll need to do this twice with each supplier. 

What contributes towards the cost of business gas? 

Suppliers calculate the cost of your business gas based on a few factors. They include: 

• The type of business 
• The sector you operate in 
• The size of your business 
• Your location 

Costs can also depend on the type of tariff you choose. The main kinds of business energy tariff are: 

• Fixed term – Charges are set at a fixed cost for a certain length of time, usually one to four years 
• Variable rate – Rates can go up or down depending on the state of the market 
• Extended – When your contract runs out with your supplier, they may offer you an extended or blend tariff 
• Flex approach – You bulk-buy energy in advance, giving you access to wholesale rates 
• Pass through – Your bill is split between fixed wholesale rates and other charges like National Grid and Transmission Network Use of System 
• Deemed – If you move into a property without arranging a new contract you’ll be placed on more expensive deemed rates 
• Out-of-contract – This is the (often expensive) tariff you’re automatically put on if you don’t take out an energy contract 

Should you fix your business gas rates? 

Fixing your rates is the only way to shield your business from price volatility and rising rates. Energy prices usually rise gradually and in the same way other prices rise with inflation. This is why agreeing a new contract early can save you money. 

Remember, it’s unlikely that the new rates you agree will be less than those you’re currently paying, but will almost certainly be less than your supplier’s out-of-contract rates. That’s where you save money by switching. 

Business Gas FAQs 

To help you better understand how business gas switching works, here are the answers to some frequently asked questions.

Should you pay VAT on your business gas bills? 

It’s most likely your business will be charged the standard rate of 20% VAT for its gas, but discounts are available for some businesses, as well as certain not-for-profit and charities. You might also be in line for a reduced rate of just 5%. Learn more at our guide to VAT and business energy. 

How to get the best gas rates for multi-site and high-consumption businesses 

If your business is located across several sites, and each location has its own meter, it could be more cost-effective, and certainly more convenient, to have one provider overseeing your energy supply – you’ll have one bill showing the energy consumption of each site, and one renewal date. 

Speak to the Bionic energy experts about gas supply for large businesses and we will help you find the most suitable and cost-effective multi-meter and multi-site energy plan. 

Are business gas prices capped? 

Unlike domestic gas prices, which have been subject to a price cap to keep bills relatively low, business gas prices are not capped. This is why it’s important to compare business gas prices and fix your rates. 

How to cut the cost of your business gas bills

• Install efficient tech. Try appliances with higher efficiency ratings, upgraded boilers, and other eco-friendly technology 
• Invest in your premises. Make your premises as green as possible. You can insulate the walls, ceilings, and floors, or install double glazing
