Switch your business energy supplier and save thousands
The UK has one of the most deregulated, competitive energy markets in the world. Business owners and UK households struggle to choose between all the options on the market. Our energy experts have created a comparison generator that solves this issue of finding and comparing business energy and home energy.
When you compare energy suppliers with SwitchWhiz, you get the best of both worlds. Our intelligent comparison tool will show you the best energy suppliers for your home or business. Small, medium, and large businesses, as well as domestic customers can find affordable rates and packages that suit their needs.
Energy suppliers don’t reward loyalty like they used to. If you stay with the same supplier year after year, all you’ll get is a heftier bill.

We have created a comparison engine that contains a trusted panel of 14 energy suppliers on the market. Even better, it only takes a few minutes!

The UK energy market has changed substantially over time. In 2010, just six business energy suppliers controlled the entire energy market, but gradually other companies started to make an impact What’s more, the acquisition of npower by E.ON means that as of 2022 the traditional Big Six became a Big Five, although the largest six energy suppliers still share 70% of the UK electricity market.
Whether you choose a Big Six supplier for your business electricity is up to you. You may trust the stability of a larger company more, or prefer the competitive tariffs or customer service that a smaller supplier can provide - although these smaller suppliers can go bust from time to time!
However, challenger energy suppliers are known for offering great customer service whilst still providing some great deals on gas and electricity in comparison to other suppliers on the energy market.
For example, Valda Energy may be a challenger to the business energy sector, compared to heavyweight British Gas, however their business electricity rates are very competitive for business owners.
The current “Big Six” of domestic electricity suppliers is as follows, according to Ofgem's data:
If you own a large business, the chances are that your energy expenses are through the roof. The consensus is that big businesses have to be with the Big Six suppliers, but the truth is that there are lots of options out there. To find the best business energy suppliers for your needs, you have to compare the market. You can start with our comparison tool, which provides impartial advice to business owners who want to take control of their finances.

Green energy is more important than ever before. The UK government has committed to hit Net Zero by 2050, and big energy suppliers have a responsibility to reflect that.
Suppliers can show their commitment to green energy in all sorts of ways. Some suppliers will plant trees for every year that you sign up for an eco-friendly contract, and others provide 100% renewable electricity as standard.
Our comparison tool will find the best business energy suppliers for environmentally-conscious business owners. Just add your details, wait for 30 seconds, and choose from a range of green deals.

No, you don’t have to worry about that. Suppliers can turn off your electricity or gas supply, but only if you haven’t paid your bill.
It shouldn’t take more than 14 days to switch from one supplier to another. We will assign a dedicated agent to your account who will make the switch as easy as possible. If you have any questions or concerns, you can give them a call.
The Energy Switch Guarantee is a set of promises. Suppliers can voluntarily sign up for the Energy Switch Guarantee to commit to 10 promises. One of the biggest promises is that your service will not be interrupted.
Opus Energy has not gone bust, and still exists, but the energy supplier is no longer taking on any new customers nor renewing existing customers. In September 2024, the majority of Opus Energy business customers were sold to EDF Energy, with some customers continuing to be served by Opus, although in terms of switching to Opus Energy, the energy supplier has ceased trading.
Customers unaffected by the sale will remain with Opus until their contracts end, after which point they will remain with Opus on a variable tariff, however they can choose to switch to a new business energy supplier for a fixed rate.
