Whether working from home or investing in business energy for a massive corporation, switching to business energy comes with its fair share of considerations, one of which is energy usage.

Unlike the majority of people, who leave their house as early as 6 am and don’t return until 6 pm, business energy is often on all day, every day. However, this isn’t to say electricity and gas business energy contracts are higher in cost per unit.

In this guide, we’ll discuss the differences between business energy contract and domestic energy contracts, the additional costs you will need to consider and how to find the best energy suppliers.

What Are Business And Domestic Energy Tariffs?

Business energy contracts differ a great deal from the tariffs sought out by domestic energy customers. Why? Because business gas and electricity usage has different necessities to that of domestic energy usage.

Despite the unit measurements of business and domestic energy tariffs amounting to the same, they quite simply aren't the same. The business energy contract plans vary in both cost and contract particulars.

One of the biggest differences for domestic customers? They find it relatively easy to switch from one domestic energy provider to another, whilst choosing the correct and most cost-effective gas and electricity supplier for your business can be a time consuming and often confusing process.

We’ve created this handy guide to help you pick the best gas and electricity deal possible, one that is suited to both your needs and the requirements of your company.

Which Energy Tariff Is Cheaper?

All in all, business energy tariffs are cheaper than domestic energy tariffs, particularly in terms of the average unit rate. The bigger the business, the less the unit rate will be. However, you need to consider more than the gas and electricity unit rate alone.

For example, additional costs businesses will incur that domestic energy customers won’t, such as VAT. Domestic energy tariffs are privy to just 5% VAT, while businesses energy tariffs must succumb to 20% VAT.

Other costs businesses must consider include CCL, which is also known as the Climate Change Levy. At present, this equates to a rate of 0.188p per kWh for gas and 0.541p per kWh for electricity.

Although the unit rates are lower for business energy tariffs, it is the additional charges you will need to take into consideration if you wish to find business energy cheaper. These costs can have the effect of pushing up costs on a whole. This is when shopping around for the best deal is a must.

It’s also important to consider other types of energy, for example, those using renewable energy will be privy to CCL and VAT exceptions, both of which could make a huge difference to your overall energy tariff, we discuss this in more detail below;

  • Businesses are not required to pay CCL charges on renewable energy usage.
  • Those who use less than 33 kWh of electricity on average per day and 145 kWh of gas per day are not required to pay CCL and will only be privy to 5% VAT. (To sum this up, this is equal to a total of 52,925 kWh of gas per year and 12,045 kWh of electricity – this is a vast amount more than domestic energy usage.)
  • Business customers who own business’ that boast a residential aspect are not required to pay CCL and will only have to pay a total of 5% VAT. This is true for those who own campsites, run B&B’s, or own a care home.

How Do Business Energy Contracts Differ From Domestic Contracts?

One of the key differences between business customers and domestic energy contracts is that businesses must pick a gas and electricity supplier for a set period. Domestic energy tariffs on the other hand tend to come in the shape of rolling energy tariffs and as such, there is no expiry date for domestic customers.

The supplier will continue to supply energy to domestic customers on their current tariff until the homeowner decides to switch or upgrade their domestic energy tariff.

Here are a handful of ways business energy and domestic tariffs differ:

Cheaper bulk energy

Business energy suppliers have the option to purchase business energy in bulk, which means the supply will last the entire contract duration. Domestic gas and electricity suppliers on the other hand will purchase energy month by month.

What does this mean? Business energy suppliers are privy to energy at a better rate, which the business owner is also able to benefit from. As we have mentioned, both VAT and surplus charges can increase business energy costs quite significantly, which is why it’s important to learn more about these additional costs first.

Longer & more complex contracts

The majority of modern-day businesses choose energy contracts that span a lengthy period - usually around five years. What does this mean? First and foremost, the price is often more competitive as the supplier can buy energy in bulk, thus lowering costs on a whole and making business energy cheaper.

One downside of this? It means the business owner is tied into the deal for a set amount of time, which is why it’s important for business customers to pick the best contract from the onset.

Price fluctuations

When you invest in business energy, you’re investing in a bespoke contract, designed to suit the needs of your company and staff. The cost of this contract will be a one-off fee that won’t (unlike domestic contracts) change throughout the year.

This gives business customers peace of mind when it comes to repayments, as there will be no proven fluctuations to deal with. To ensure you get the best energy tariff from the onset, visit https://www.businessenergyuk.com and request a quote within 60 seconds.

No "cooling-off" period

Business energy contracts don’t tend to come with a cooling-off period. This means that when the contract is signed, no changes can be made. It also means commercial energy deals are privy to a set payment, rather than one that fluctuates, which often makes them cheaper than domestic energy on a whole.

For more information, read the electricity supply terms and conditions before making a decision on your business electricity to ensure you get the best business energy deals.

No contract termination

If you’re happy with your business electricity tariff, this will continue to roll over year on year without you having to lift a finger. It’s only if you wish to change your commercial energy tariff, that you will you need to terminate the contract when your tariff is up for renewal.

Higher VAT charges

VAT, or Value Added Tax, comes in the shape of a government tax, which is applied to all goods and services purchased or sold for consumption or use by individuals or businesses. In a nutshell, this means your commercial energy is privy to VAT, and as such, all companies are required to pay a percentage of VAT on business energy prices.
