Prices are highly individualised in the business energy market. Providers can give you a quote to get a better sense of what your energy cost will be. This will be based on your postcode and your average consumption, but companies might want a little more information about you and your business.

If you’ve just moved into a new premises and you haven’t sorted out a new energy deal, you’ll be moved onto a deemed/out of contract tariff with the previous occupant’s supplier. And yes, the rates are higher than on regular tariffs.

Your cheapest option is to go on a fixed term deal, but some like the flexibility of a variable tariff which has a fluctuating price to reflect the market.

What should I be looking for from my business energy supplier?

Now, there a few features which set energy suppliers apart from each other, but a lot of features are largely the same.

Being able to give you a smart meter and having an online platform or app to manage your account are standard features so you shouldn’t be wooed by them.

Instead, focus on price and the flexibility of your tariff as well as the firm’s reputation and customer service record. Plenty of providers offer an eco-friendly service now which is a plus if becoming greener is a goal for your business.

We’ll run you through some of the best providers for smaller businesses in the UK and what they can offer you. For the sake of simplicity, we’ll stick to the fixed and variable tariffs.

British Gas

You don’t need us to tell you that British Gas is one of the biggest energy suppliers in the UK.

They can install, maintain and repair your commercial gas boiler as well as maintaining your plumbing and drainage. They also have a business moving team to make switching easier.


British Gas have a mix of fixed term and variable tariffs.

Fixed rate energy plans means that the unit rate stays the same for one, two or three years of your plan.

On the 30-day rolling tariff, your unit rate and standard charge could go up and down but you’ll have at least 30 days’ notice before these change. This tariff is only available to customers agreeing a new supply contract. However, you can upgrade to a fixed price plan by giving 30 days’ notice and paying all of your outstanding bills.

If you have a half-hourly energy meter, you’ll get a tailored price based on how and when you use electricity.

To get a multi-site and multi meter electricity deal, you must be new to British Gas and use more than 100,000 kWh a year.

The Commercial Landlords plans are suitable for those with one property or a portfolio. Choose from fixed or 30-day rolling contracts above. Additional safety checks are available from British Gas.

Unlike some of the others, npower has a few different tariffs to suit different businesses.

Npower offers up fixed term contracts up to four years. You do have the option of cash or cheque payments, but they come with a 5pc surcharge. The Direct Debit option doesn’t come with a surcharge.

The Business Online Saver is fixed is for 12 months.

The variable tariff lets you change suppliers with 30 days’ notice, energy prices move up and down with the market. You can pay by cash or cheque, but you’ll dodge the 5pc surcharge if you pay by direct debit.

If you generate your own energy – say, through solar panels – you can sell it with the Smart Export Guarantee tariff. It replaces the previous Feed-In Tariff (FIT). You’ll need to apply through E.ON who have eligibility criteria of their own.

The Standard Fixed is fixed for up to one year and comes with a 30-day termination notice period. It lets you move to a new product any time with no fees.

As is the nature of these deals, the price varies on a Standard Variable tariff, but you can move to a new ScottishPower product without an exit fee.
