When can you switch energy supplier?


Whether you run a tiny tea room, or a group of gastropubs, you’ll need a good deal on business gas to make sure you’re not paying over odds for your energy – but if you’ve not switched supplier recently, that’s exactly what you’ll be doing.

Before you switch, though, it’s worth knowing a bit more about how business gas contracts work – although the switching process is pretty much the same as when you switch domestic supplier, there are a few differences you’ll need to be aware of.

Our switching service is completely free and impartial, so it won’t cost you a single penny or a second more of your time to search the entire energy market. Give us a call now on 0800 088 6986. Or, if you prefer, leave us a few details, and we’ll give you a call back.

When you speak with our energy experts, you’ll need to give them a few details about your business and its energy use - the more accurate this information the more accurate our quotes, so grab your latest bill and make a note of the following:

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

Once our energy experts have all this information, they will gather together the best value tariffs available, so you can make an informed decision on who will be supplying your gas. Simply let us know which deal you prefer, and we’ll set up your new contract with your new supplier.

It’s worth noting that you won’t be able to agree on a new deal until your current one has entered its ‘renewal window’ – for more information, check out How to switch business gas and electricity.

Why switch business gas supplier?

Unlike domestic energy deals, there are no off-the-shelf tariffs, and all commercial contracts are designed to meet the specific needs of each individual business.

But switching to a better-priced business gas tariff is a quick and easy way to cut costs, and it won’t impact 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’ve just moved into a new business premises, or been stuck with the same supplier for years, you’ll have been placed on an expensive deemed rates or rollover tariff, but making the switch means you can choose between a better-priced fixed or flexible rate tariff.

Fixed rate tariffs are generally the more popular option, as they protect against price rises and make for more straightforward monthly budgeting, as costs remain more or less the same (depending upon consumption).

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 decides to pass on these savings – unfortunately, even if there is a drop in wholesale prices, there’s no guarantee your supplier will lower the rate you pay.

One big advantage of flexible tariffs is that some allow you to give just 30-days’ notice before switching, which could be ideal if you’re at a premises with a short-term lease, or run a pop-up shop. If you’re on a fixed tariff, you often have to give up to six months’ notice.

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.

What happens when you switch business gas?

Once you’ve agreed to sign up with a new supplier, you can sit back and relax until the day of the switch - we’ll pass on your details to your new supplier, and they will then sort out the rest of the switch with your current supplier.

Your new supplier send you details of the switchover date and a copy of your energy contract – be sure to thoroughly check the details, as there is no cooling-off period with commercial deals. When everything is agreed, you’ll just need to take a meter reading on the day of the switch, and make sure any outstanding bills have been paid – your old supplier can block your switch if you owe them money.

Your new supplier will carry out a credit check will be carried out on your business, the results of which can affect the rates you’re offered and even the suppliers who will offer you a contract.
