Here’s what you will find in this guide:


Over recent years the business energy market has seen increasingly lower barriers to entry, which leads to more competition and lower tariffs. As a business, this is great news. You have a greater selection of available gas tariffs that make it possible for you to browse and, if necessary, switch to the best-value tariff.

Problem is, most businesses are unaware of these potential savings. It also often seems much easier to simply stick with your current business gas provider.

But actually, Ofgem reports that customers are paying up to £300 more on their gas bills because they are using a poor-value tariff.

At this point, you are probably thinking to yourself. “Even if there are lower business gas prices in the market, switching is a costly and complicated process right?”


Generally, providers are more than prepared to accommodate you switching to them, even if it is on short notice. They ensure that your business continues to have uninterrupted access to gas at all times, whether or not you have entered into a contract with them.

So now that you know there aren’t really any downsides to finding and switching to a better business gas tariff, let’s crack on.


Business Gas Rates Comparison

Business gas prices consist of the Unit Rate (p/kWh) and a Standing Charge (p/day).

The Unit Rate is the price of each unit of gas that is used, calculated in pence per kilowatt hour or p/kWh. Typically, the unit rate ranges from 2p/kWh to 7p/kWh between suppliers.

The Standing Charge is the daily cost of keeping your gas supply open. You can also think of the standing charge as a rental fee you pay to the supplier.

In general, business gas suppliers offer 3 types of rates: fixed, variable, and deemed (or out-of-contract).

You find fixed and variable rates as part of a contract, with fixed-rate contracts offering cheaper prices since you are also agreeing to a longer-term (usually starting from 1 year).

Deemed rates, or out-of-contract rates, apply when you haven’t entered into a contract with a supplier. As a result, they are usually more expensive than fixed and variable rates. You may find yourself using deemed rates when you are considering a switch and don’t wish to commit to anything just yet.

In the table below, you will find a comparison of the deemed rates between the best business gas suppliers in the UK.

Think of them as the maximum possible prices you would face with each supplier, and it should also give you an idea of their fixed and variable rates.

Business Gas Suppliers

If you are wondering why some of these suppliers sound familiar, it’s because 6 of them are responsible for supplying 79% of the gas market in the UK.

These business gas are known as the ‘Big Six’, and their market shares are as such*:

  • British Gas (31%)
  • SSE (11%)
  • E.ON (11%)
  • EDF (9%)
  • ScottishPower (9%)
  • Npower (8%)

*by end of Q4 2017

What Affects Business Gas Rates?

Business Size

In short, larger businesses typically use more energy which allows suppliers to offer lower rates, compared to the rates for smaller businesses that don’t use as much energy.

Suppliers use your previous gas usage data as an indicator of your business size and gas rate. If your usage is above a certain number, you’ll qualify as a large business and receive lower rates.

Therefore, you need to have an accurate idea of how much gas your business uses each month. If you are unsure, check your previous billing statements and meter readings, and you should be able to find out your monthly usage.


Contract Length

Longer fixed-rate contracts, such as those lasting over 1 year, generally have higher rates. This is because your business gas rates will remain fixed for a long period of time, and so suppliers need to accommodate for the potential loss by charging a slightly higher rate than their short-term contracts.

On the other hand, short-term fixed-rate contracts that last for only a year or less will almost always see prices going up each year, which means that they may have to constantly switch suppliers every year to get the lowest business gas rates.



Businesses that operate in city areas usually receive lower rates compared to those in rural areas, because they are in areas with better access to distribution networks for gas supply. The higher rates for businesses in rural areas reflect the increased effort by the supplier to get the gas to the business.


Payment Method

In general, suppliers offer discounts when businesses make payments through certain channels such as monthly direct debit. This allows you to reduce your costs, while the supplier receives faster payment by directly debiting funds from your account.


How to Choose the Right Business Gas Plan and Supplier

Know your gas usage

Before deciding on a business gas tariff and supplier, the first step you should take is to find out how much gas you use. This gives you an idea of your business size and makes the selection process much easier when you know which rates apply to your business.

Having this information on hand also allows suppliers to understand your business better and suggest the most suitable tariffs for you.


Understand your business needs

You need to also consider what type of tariff and contract is the most in line with your business needs. For example, if your gas usage fluctuates throughout the year then you may want to go for a flexible contract that allows you to pay-as-you-go, based on how much gas you use.

Moreover, you may want to enter a long-term fixed-rate contract that guarantees a certain price over time. But you could also take your chances and switch providers every year to ensure you always have the lowest rates in the market.

Once you are certain about what type of contract you want the search process becomes much easier.


Type of Energy

Finally, make a firm choice on the type of energy you want to use. If you want to be environmentally-conscious, then you select a provider that offers business gas tariffs from 100% renewable energy sources.

Well done.

At this point in time, you are ready to begin selecting the best gas tariff for your business. Equipped with the information in this guide, you can bet that soon enough you’ll be saving big on your monthly gas bills.
