The structure of the UK energy market makes it seem quite difficult to switch business energy supplier. As businesses much switch their business electricity and gas supplier separately, it usually means double the work for the person responsible in the business.

In this guide, we’ll provide you with advice on how you could save time, terminate your current contract and initiate a new agreement for a contract better suited to your business and its energy requirements.

The Process of Switching Business Energy Supplier – Overview

Unlike the residential market, it’s not usually straightforward to switch to new energy rates for your business. Every business tariff is for a fixed length of time of at least 12 months. Some contracts last three years or more, and you’re tied to this agreement until it expires. It is not possible to exit your business electricity or gas contract earlier than agreed.

Thanks to rules set out by the Energy market Regulator Ofgem, smaller businesses receive reminders from their current supplier about contract endings and renewals.

This comes in the form of a two-page letter which includes details about terminating your current contract and the potential pitfalls of ignoring its contents.

If you don’t fall under the “micro business” clauses, then the onus is on your company to manage the terms and conditions set out.

What Happens If I Don’t Switch When My Business Contract Ends?

If you fail to change suppliers or at least renegotiate rates with your current energy supplier, you are likely to be placed on out-of-contract rates. These rates are set by business energy suppliers. These rates can cause an increase of up to 50% on your energy bills and could lead to you spending significantly more than needed for your business energy.

What do I need before comparing business energy?

Before you begin to compare business energy deals, you should ensure that you have a recent bill or your contract to hand. This will contain all the information you need, including your annual usage and meter numbers. You will have a separate meter number for your gas and electricity. You can read more about these here.

If you decide to use our comparison engine, having this information to hand will provide you with a true reflection of the savings you can make on your business energy.

How soon can I switch business energy suppliers?

It’s usually recommended that you switch business electricity suppliers when your contract ends to avoid any large penalty fees. You should also consider switching your business gas supplier at the same time so you can take care of your business utilities in one go.

The process for changing energy suppliers usually takes between four and six weeks. You should ensure that your new supplier has all the information they need in order to avoid any delays.

It’s important for you to select the right business energy deal. Here’s a list of our top tips for switching business energy suppliers:

  2. Be open to using a smaller, independent supplier as they often offer cheaper rates.
  3. Use a comparison tool to find out which energy suppliers can offer you the best deal.
  4. Be wary of renewal offers as they aren’t usually as cheap as rates offered elsewhere
  5. See if suppliers offer additional services and products such as smart meters, which can be used to help you monitor your energy usage.

In 60 seconds, you can compare business electricity prices and select the tariff that’s right for your company.

Switching Instructions

There are just three basic steps to change your energy supplier:

The Three Steps to Switch Business Electricity Supplier

Once you have completed these steps, your new rates are effective when your new contract begins.

Step 1: Terminate Your Existing Agreement

Contract termination notice window of opportunity

If you don’t terminate your existing agreement, your current energy supplier will extend it for another term.

This extension usually involves an increase in your rates. Increases of 100% have been reported for these follow-on contracts, although 30% increases are more common.

If you don’t exit your contract, you’ll see substantial increases in your unit price and standing charge.

Pitfalls in the Termination Process to avoid

  1. You only have a specific time to invoke the termination.
  2. If you don’t terminate, your contract will be rolled over for at least 12 months.
  3. An expired contract with no new agreement invokes “out of contract” rates.

Rollover and Out of Contract Rates

The worst case scenario for a business owner is if the termination goes ahead, but you haven’t signed a new contract. In these circumstances, you’re in no contract at all, and the energy companies have special rates that they will apply.

These are termed “out of contract” rates, and these are even higher than the rollover rates. These tariffs are the most expensive available and will be paid until you sign up for a new contract.

Most business and commercial customers have energy contracts for fixed periods lasting one year or longer. Within the contract wording, there will be a specific period of time when you can invoke termination and switch to another supplier.

These terms are also shown in your renewal letter that is sent by some suppliers. If you miss these deadlines, you’ll be automatically rolled over for another year.

Step 2: Check the Latest Prices Available

Set of balancing scales

Once you have the termination process in hand, you can start to check for the latest energy prices.

You have the option of obtaining the data yourself, using an online comparison service or using an accredited energy broker. Brokers can often find cheaper dealsthrough their extended relationships with a wide range of energy suppliers.

At Business Electricity Prices, we can quickly help you find the energy suppliers offering great prices for your business and manage the whole process on your behalf.

Ways in Which to Obtain Quotes

Here are the choices you have to find the latest and the best available prices in the marketplace.

  • Visit or telephone each of the big six suppliers and ask for a quote. There are other companies available that may offer lower prices, however, this can be time consuming.
  • Use an online service of a specialist who has the expertise and knowledge to know the best time of year to strike a deal. If you enter your details here, we’ll find you great energy prices your business.
  • Contact an energy broker who can help manage the entire process on your behalf. Their services include pricing; help with reducing your consumption through efficiency and carbon offset credit obligations you may have.

Step 3: Move to Your New Provider

Say Yes to switch your contract

The actual switching process can be longer for a business customer versus the residential market.

Your new contract cannot begin until your existing agreement has expired. If the expiration date is three months from now, then that’s when the new agreement commences.

Obtain meter readings to confirm your final invoice.

The new contract needs to be legally signed by a signatory that’s authorised to do so. There are services that now allow electronic signatures which are accepted by energy companies, although they are limited.

Checklist Summary

Prices do rise and fall during peak demands for power as the wholesale market adjusts to the UK’s energy requirements.

The winter months usually have the highest prices during the year. Price quotes are usually only valid for 24 hours because of the volatile nature of the industry. If you receive a quote that’s suitable, then it’s best to take advantage of it at that time.

Here’s an overview to switching your electricity:

  1. Terminate your contract within the terms outlined to avoid rollover contracts.
  2. Get new price quotes and compare them to find the cheapest available.
  3. Ensure you sign up to a new agreement to avoid out of contract rates.
