Business Energy Comparison

The expert guide: ensure your business has the
best energy provider to fulfil your needs

The complete business energy comparison guide


UK businesses currently boast the overall lowest energy prices throughout Western Europe, but if you made a business energy comparison, would you be confident you’d find that you’re on the most cost-effective tariff for your business?


Of course, energy prices rise and change continually too, so you may have been with the most suitable supplier 12 months ago, but now, you may stand to reduce costs considerably by switching.

Subject to your contract, you have the right to change your energy supplier whenever you want, so keeping an eye on the changes in energy supplier tariffs could save your business a lot of money.

Are business electricity rates cheaper than domestic?

When comparing average unit rates, businesses typically use a lot more energy than domestic residences. In fact, the average small business spends over £12,000 on electricity and over £7,000 on gas per year.

That’s a lot of expenditure, so if you’re paying more, you should compare business energy suppliers to see how much you could save.

You should also take into consideration VAT and the Climate Change Levy (CCL). For a domestic energy tariff, you’ll only pay five per cent VAT on your energy, while businesses typically pay 20 per cent.

For businesses, the current CCL rate is 0.541p per kWh for electricity and 0.188p per kWh for gas.

If you’re working from home, there are a number of factors you should consider, many of which you can benefit from when you choose a business energy tariff over a domestic energy tariff:

  • A cheaper business ‘profile’

 

There’s no need to install a new meter when you switch to a business energy tariff, but your meter will be given a new ‘profile’. This will assess your consumption differently than a normal household energy tariff. That’s good news for your expenditure as the profile will assume you use more energy in the day – when it’s cheaper.

  • Fixed tariffs and flexibility

 

Tariffs from business energy suppliers are usually fixed price. This means you can pay the same rate from the start to the end of the contract. And this doesn’t mean you have to be tied into a long contract – business energy supplier contracts can be anything from one month to five years. This can help with your budgeting and helps protect you from price rises.

  • Energy usage and business status

 

If you want to switch to a business tariff, you need to be using about 50 per cent of the energy in your home for business purposes. And you need to be a registered business. Proof you’ll need to provide to a business energy supplier may be as simple as a business rates document or even your website or a compliment slip.

How much does electricity cost per month for a business?

When measuring how much you should be paying for electricity from your business energy supplier, you should assess the price per kilowatt-hour (kWh).

For SMEs, recent rates have varied from 13.2p to 16.7p plus VAT for unit prices per kWh. A standing charge is also added.

What is the average cost of energy for a small business?

As well as comparing electric usage for your business, it’s a good idea to look at the typical overall energy you’re likely to be using, and how much it will cost.

If you’re paying too much for business energy, you could save hundreds of pounds by switching. But before selecting the right energy supplier for your business, it’s best to look at the averages for companies of similar size.

Here, we compare business energy costs for small businesses to large businesses.

BEWARE OF THE CONTRACTUAL TERM

When choosing your business energy supplier, you’ll probably be offered a fixed price for a fixed term – how most business energy prices are calculated. As wholesale prices are likely to fluctuate, it may benefit you to try to negotiate for a one-year contract. This means, if you spot an energy deal that’s better than your current provider offers, getting out of your contract to switch will be much less difficult.

Some tariffs come with a standing charge while others have a split tariff where the initial units are charged at a higher rate. Whether or not a standing charge applies to you will depend on the amount of electric consumption you have per month.But not all companies need business internet. And it doesn’t just depend on your business size, it could be the type of work you do.

The big six energy suppliers

Who is the best business energy supplier?

Although there are currently over 50 business energy suppliers in the UK, most company’s choose one of the big six as their supplier of choice. Undoubtedly, a big part of this is opting for a trusted and well-reviewed brand. However, although there are obvious benefits to choosing one of the big six, it’s always worth comparing them against some of the other energy providers in the UK who may be able to give you a more personal service and even lower costs.

Here, we’ve listed some of the main benefits of the big six business energy providers as well as some of the independent, smaller energy suppliers.

Who is the cheapest business energy supplier?

So, let’s get down to cost – who is the cheapest energy supplier? After all, reducing your cost is probably what you’re here for.

Customer service is also important, so we’ve included the consumer rating (calculated by combining the Which? consumer rating and Trustpilot score), and you can also see the time taken to speak to customer services over the phone for each of the energy suppliers.

As well as comparing the big six energy suppliers for cost, we’ve also looked at some of the cheapest independent business energy suppliers.

The best independent business energy suppliers

For decades, the big six monopolised the market, with customers automatically assuming they offer the most competitive deals. But that was not always the case, and it certainly isn’t now with the emergence of some genuine independent rival business energy suppliers. And these new energy companies are finding it easier to connect with a public that is increasingly savvy, and increasingly dismayed by the big corporate energy companies.

Since 2005, the big six have enjoyed between 10 and 30 per cent of the electric market each. But although independent energy suppliers were almost non-existent in terms of market-share around 2005, over the years they have grown to take just under 20 per cent for themselves combined.

A similar trend is evident with gas (although British Gas had over 55 per cent in 2005, steadily dropping to just over 30 per cent in the last couple of years).

Independent business energy suppliers don’t have the stature any of the big six can boast, which is why the focus their efforts on making sure their service is the best and cheapest it can be.
