There are over 100 regulated commercial gas and electricity suppliers operating in the UK. While the majority of customers choose the “Big Six” for their business energy deals, there are also competitive rates available from the independent operators in the market.
Each supplier has a slightly different service offering to business users whether that be 100% renewable energy generation, online account management or the cheapest price. You should, therefore, compare the whole market before making a decision on your next contract.
The table below is a list of the “Big Six” business gas and electricity suppliers, their current commercial market share data and their original geographic region.
|Energy Supplier||Geographic Base||Market Share|
|EDF||South East, London||20.4%|
|E.ON (Powergen)||Central, East Midlands||15.9%|
|Southern Electric||South England||12.2%|
Data source: Cornwall Insight. All of these companies can supply any premises throughout England, Scotland, Wales and Northern Ireland. Eire has their own specific regulated market and arrangements.
If you use an energy broker for your quotes, then ask to see all market suppliers when you receive your prices. Not all suppliers compete in every region or for every type of meter. For example, some won’t tender for half hourly meters because of the time and data processing involved.
Some companies only supply electricity while others only deal with the light usage side of the industry for micro and small business owners like shops, offices, and restaurants.
All UK energy suppliers use a different mix of primary fuel sources to generate the electricity you use. The mix is vastly different from each supplier. The graph below shows the different classifications of coal, natural gas, nuclear and renewable sources.
Source: The Big Six suppliers and Ofgem. Each supplier submits their fuel mix data to Ofgem each quarter who also publically display the results.
Ofgem has licensed 128 different companies to provide domestic and commercial buildings electricity supplies. In addition to these organisations, a further 39 companies only provide non-domestic premises with electricity. These are listed below, together with the company registration number in parenthesis.
When you switch from your current energy provider only your invoicing terms change. The cables connecting your premises to the National Grid transmission system won’t change as they’re owned and managed by the grid.
Almost all the companies listed above can supply both gas and electricity either as a single fuel or a dual fuel contract. Changing your current plan by signing up to a new company could reduce your costs.
A single 2-minute telephone call is all it takes to start finding a cheaper gas and electricity supplier than your contract. We won’t pressurise you into accepting something that’s not right for you or bombard you with jargon you might not understand.
You can check your renewal prices against average electricity prices per kWh to see the indicative savings you could make. To provide you with an accurate quote we just need your full address including the postcode and your annual consumption.
Our automated system then provides a range of contracts you can switch over to lasting from one to five years. We don’t charge for this service as we receive a commission from your new supplier.
