A guide to small business energy and micro business energy

Micro business energy contracts work a little differently from those offered to bigger businesses. We'll dive into that soon, but one thing never changes whether you run a tiny tearoom or a group of gastropubs - you need to find the lowest rates on business electricity and business gas to make sure you’re not paying over the odds for your energy.

If you’ve not switched suppliers recently or you've let a fixed-rate contract expire, there's a good chance you're paying too much to power your business. Let's take a closer look at how much the latest rates are, and find out how business energy works differently for micro businesses.

How does small business energy differ from home energy?

Unlike household tariffs, which offer a range of ‘off-the-shelf’ tariffs, business energy suppliers offer bespoke contracts that fit the needs of each business, depending on size, location, and energy usage.  

For example, micro business gas suppliers may offer competitive rates for smaller consumption brackets, while larger companies may get tailored options with different rate structures. 

The rates you’re quoted depend on things like how and when your business uses energy and where it’s located. The size of your business also has an impact – remember, a small business can have up to 50 employees. 

When you’re a business owner, every penny counts. Comparing quotes and switching to the cheapest business energy supplier can have a big impact on your bottom line.  

It's also worth noting that non-domestic energy contracts don't come with a cooling-off period, and prices aren't capped. This is why it's so important to make sure you're completely happy with the contract before you sign. 

If your business operates across multiple locations, such as a small chain of coffee shops or a few salons, you may qualify for a multi-site energy contract. This is a good way to consolidate all of your energy supply into one package, with one supplier and one renewal date.  

As a business owner, you may also use energy at different times. This is why it’s important to find an energy contract that’s suited to the needs of your business. 

What is a micro business, and how does it affect your energy options? 

Micro business energy contracts can sometimes be more flexible, offering rates based on lower consumption levels that are ideal for smaller operations. 

If you qualify as a micro business, energy suppliers will consider how and when you use energy, and you may not be bound by restrictive switching windows. 

In the UK, your business is classified as a micro business if: 

• It uses less than 100,000 kWh of electricity per year 
• It consumes less than 293,000 kWh of gas annually 
• It has fewer than 10 employees or a turnover below €2 million 

These thresholds help suppliers better tailor gas and electricity contracts to meet the specific needs of micro businesses, offering lower rates and simpler switching processes. 

Bigger businesses have a limited “switching window” which is set by the existing supplier and can restrict when they can switch.  

But micro businesses can switch with 30 days' notice. This offers a greater opportunity to find better rates without worrying about missing a specific timeframe. 

What are the benefits of switching energy suppliers for small businesses? 

Switching energy suppliers can help small businesses and micro businesses save money. Finding a supplier that offers lower prices and locking in those rates means you should save money compared to what you might pay if you roll onto your supplier’s out-of-contract rates. 

Signing a new contract to start as soon as your current one ends also means you’ll not risk an expensive gap between contracts. 

It’s not all about cost, though. If you’re not happy with your current supplier’s service levels - say they bill you incorrectly and the customer service team is impossible to get hold of - switching to a more suitable supplier can save you a lot of frustration. 

How to cut your small business energy bills 

Switching to a better-priced contract is just one way to cut your business energy bills. Here are a few other things you can do to help cut your bills further and keep costs as low as possible. 

• Monitor your usage: Regularly check how much electricity and gas you’re using. Fitting a smart meter can help with energy monitoring. 
• Compare regularly: Regular small business energy comparison helps you stay updated on the best rates and options. The energy market is dynamic, so even a small shift in rates can mean big savings. For more information, check out our guide to how the UK energy market affects your energy bills.
• Negotiate multi-site contracts: If you operate multiple locations, look into a multi-site contract. Suppliers often provide better deals when covering several locations. 
• Stay informed of contract details: Ensure you understand your current energy contract’s terms. By knowing your end date and notice period, you’ll be ready to switch to a cheaper business electricity supplier at the right time. 

How to get the best energy rates if you work from home 

If you work from home but need a commercial energy tariff, you’ll typically need to prove that at least 50% of your energy usage is for business purposes. If you meet these criteria, you may qualify for small business electricity rates. 

Remember, lighting, heating, and specific office equipment dedicated to business activities contribute to this threshold. Many suppliers offer competitive rates for home-based businesses, so it’s worth discussing your options to secure cheap business energy. 

What if your business energy supplier goes bust?

If your business energy supplier goes bust, you'll automatically be placed with another supplier that is chosen by Ofgem, the energy regulator. If this happens, you won't be tied in and can arrange a fixed deal with that supplier or switch to a new supplier. For more information, check out our guide to what happens when your business energy supplier goes bust.

How to switch small and micro business energy suppliers 

If you're a small or micro business owner looking to switch suppliers, get in touch with the team at Bionic a couple of months before your existing contract expires. As a rule of thumb, start collecting quotes as soon as your current supplier gets in touch with a renewal offer. 

MoneySuperMarket has teamed with Bionic to make sure you benefit from their years of helping business owners find the best small and micro business energy rates.  

Getting quotes early means our energy experts can check out the latest deals from our panel of suppliers and lock in your new contract to start when your current one expires. This can help you avoid the problems of price volatility.

If you're not currently under contract, then you should arrange a new deal as soon as possible to secure cheaper rates and lower your bills 

Securing the best business gas and electricity prices doesn’t need to be complicated. By comparing rates from our panel of suppliers, you can find an option tailored to your unique needs.

Small business and micro business energy meter installation FAQs

Still unsure about how energy contracts work for small businesses and micro businesses? Check out the answers to our most frequently asked questions.

Can small businesses negotiate energy prices in the UK?

Yes, some suppliers offer bespoke energy quotes for small businesses, especially if you have consistent usage or are willing to sign a longer contract. Comparing multiple suppliers increases your chances of finding more competitive or flexible pricing options.

Why do small business energy prices vary so much?

Small business energy prices vary due to factors like location, energy usage, credit history, and contract length. Suppliers also adjust rates based on wholesale energy costs, which can change frequently, meaning quotes can differ significantly between providers.

What is the cheapest way to get business energy for a small company?

The cheapest way is to compare multiple suppliers and switch to a fixed-rate deal when prices are competitive. Avoid rolling onto out-of-contract rates, as these are usually much higher than negotiated or newly agreed tariffs.

Do small businesses pay higher energy rates than larger companies?

In most cases, small businesses pay higher unit rates than large companies because they use less energy and have less negotiating power. Larger organisations often benefit from bulk purchasing and bespoke contracts.

What happens if I don’t renew my business energy contract on time?

If your contract ends and you don’t switch or renew, your supplier will usually move you to a deemed or out-of-contract rate, which tends to be significantly more expensive than fixed or negotiated deals.

Can switching energy suppliers reduce costs for small businesses?

Yes, switching energy suppliers is one of the most effective ways to reduce costs. Many businesses save by moving to a cheaper tariff or supplier, especially if they haven’t reviewed their contract in over 12 months.

Are fixed or variable tariffs better for small business energy?

Fixed tariffs provide price certainty by locking in rates for the contract term, while variable tariffs can go up or down depending on market conditions. Most small businesses choose fixed deals to avoid unexpected cost increases.

Does energy usage time affect small business energy prices?

Some business energy tariffs offer different rates depending on when you use energy, particularly for electricity. Shifting usage to off-peak hours can help reduce overall costs if your tariff supports time-of-use pricing.
