Understanding the £75 referral credit for businesses

One of the biggest attractions for new business customers is Octopus Energy’s special referral credit.

Here’s how it works:

• £75 Credit for business customers: While households get £50 when they join using a referral, businesses get £75. This is a straightforward credit on your Octopus account, which you can use to lower your energy bills.
• Why this matters: Energy bills can be a significant expense, especially for larger companies. Knocking £75 off is a nice bonus that can help you manage your costs more easily when you first switch.

To qualify for the business reward, complete the sign-up directly online through the valid affiliate link. Octopus’s current terms say that phone, comparison-site, broker and retrospective sign-ups are not eligible for the reward.

Step-by-Step: How to switch and get your £75 credit

Even though the process might feel new or complex, switching to Octopus Energy is usually quite straightforward. Follow these steps to make sure you get the full referral bonus:

1. Check your existing contract
   Before making any moves, have a look at your current energy contract. Some suppliers have exit fees or notice periods that could affect the overall cost of switching. Switching is often much easier if you’re near the end of your contract. If you have large exit fees to pay however, it may be worth waiting until closer to the end of your contract before switching.
2. Find the right Octopus business tariff
   Visit the Octopus Energy website and look at their business tariffs. They usually offer a few different types, ranging from fixed rates (where your price stays the same for a set time) to flexible or variable rates (which can go up or down with the market). The site will give you an estimate of your monthly or annual bills. Octopus now even offer a business energy tariff with zero standing charges.
3. Sign up for a business account
   Start the sign-up process online by choosing the right tariff for your company. You’ll provide basic details, like your business address and your estimated usage. This helps Octopus Energy set up the correct plan for you.
4. Use the valid affiliate link
   Complete the business sign-up directly through the referral link so Octopus can track the reward. Do not sign up by phone, through a comparison site or through a broker if you want the affiliate reward.
5. Octopus handles the switch
   After finalising everything, Octopus will contact your existing supplier and handle the transition. You shouldn’t experience any interruption in your energy supply. Once the switch is complete, you’ll see the £75 credit appear in your new account.

What makes the £75 referral credit so valuable?

• Instant bill relief: The credit reduces your immediate outgoings, helping manage cash flow. This is especially helpful if your business uses a lot of energy and faces larger bills.
• A larger business offer: Households get £50 when they join through a referral, but business customers get £75. That’s a real boost right from the start!
• Ongoing savings: If you like Octopus Energy, you can share your valid business referral link with other eligible companies. Reward values and terms can change, so check them before each referral.

Tips to make the most of Octopus Energy

Getting a £75 referral credit is a nice perk, but there are other ways to keep your costs low and your business running smoothly:

• Track your usage: Octopus Energy provides various online tools and dashboards to see how much energy you use daily (or even hour by hour). Keeping an eye on this data might help you find ways to reduce consumption.
• Choose the right tariff: Some businesses prefer fixed tariffs for budgeting certainty, while others benefit from variable or “time-of-use” tariffs if they can shift energy-hungry tasks to off-peak hours.
• Watch for promotions: Octopus occasionally runs additional offers or new tariff deals. It’s good to check their site or social media channels to see if anything could further lower your bills.
• Consider green credentials: If you take pride in operating sustainably, mention you’re powered by 100% zero-carbon electricity to your own clients and customers. This can set you apart from competitors.

Potential pitfalls to avoid when switching

Although switching to Octopus Energy is usually painless, here are a few things to watch out for:

• Using the wrong sign-up route: Octopus’s terms require you to complete the sign-up through a valid affiliate link. The reward cannot normally be added retrospectively.
• Ignoring your current contract: If you’re locked into a long-term deal, you might face exit fees. These can sometimes be higher than your referral credit. So, make sure you weigh up the costs before committing.
• Mixing up domestic and business tariffs: Be clear that you want a business tariff. If you accidentally sign up as a domestic customer, you’ll only get the £50 credit and may not have the correct tariff for your business.
• Not checking usage: After you switch, don’t just forget about your energy usage. Paying attention to when and how you use power can save more money in the long run than any one-off credit.

Why “Green” energy is a big deal

Many customers now look for companies that do their part for the environment. Choosing a zero-carbon-focused supplier like Octopus Energy shows a commitment to reducing carbon emissions. This can strengthen your brand’s image and appeal, especially if you’re in an industry where customers care about sustainability.

Beyond the image boost, going green can also inspire other positive changes, like installing energy-efficient lighting or exploring ways to cut waste. Sometimes, switching to a sustainable energy supplier is the first step toward a more eco-friendly business model overall.

Sharing your referral link with other businesses

If you find Octopus Energy beneficial, you may want to share the valid referral link with other businesses in your network. Always check the current programme terms before promoting or relying on a reward.

This can help you maintain lower bills while also helping peers and partners discover a reliable, green supplier. Everyone wins.

Switching your business energy account can feel like a big step, but with Octopus Energy, it’s designed to be as smooth as possible. They offer a blend of competitive pricing, zero-carbon energy, and strong customer service. Plus, the chance to get £75 off through the valid referral link makes the move even more attractive.

Just remember: if you’re switching as a business, complete the sign-up directly through the valid affiliate link. Once you are actively supplied and your first successful Direct Debit has been taken, the £75 credit can be applied to your account under the current terms.

If you decide you like Octopus Energy’s service, you can share the referral link with other eligible businesses. Reward values and eligibility can change, so check Octopus Energy’s current terms before each referral.
